1 Claim. or. 280-713) ther, many roller skates are manufactured in the same manner. I

It will be seen that this arrangement, when one derives pleasure both fromice skating and roller skating, proves rather expensive, in view of the necessityof purchasing both of these articles. Accordingly, the broad object of the present invention is to provide a generally improved item of sports equipment, that will reduce the cost ordinarily involved in purchasing ice skates, and roller skates separately. t

To this end, the invention, summarized briefly, comprises a single pair of shoes having means on the underside thereof designed to receive either an ice skate or roller skate attachment. The invention includes locking devices designed to fixedly connect the selected attachment with the shoe, said attachment in one form of the invention comprising a transversely extending pin or shaft lockably engageable with both the attachment and the shoe. In another form of the invention, the locking means comprises a flat plate .connectible to the blade or roller skate attachment in such a position as to interengage the attachment-receiving means of the shoe, to hold the shoe and the attachment against relative movement.

One object of importance is to provide a device of the character stated that will be particularly characterizedby its relatively low cost, while at the same time being rugged, durable, and relatively simple in construction.

Another object is to so form the device that the attachment or detachment of the blade or roller means can be effected with maximum facility, and without requirement of special tools.

Still another object is to so form: the attachment as to permit any of various roller and ice skates to be connected to the shoe, as for example, both indoor and outdoor roller skates, roller skates of the racing type, racing type ice skates, hockey skates, figure skates, etc. By per-.

mitting any of these various types of roller and ice skates to be connected to a single pair of shoes, manufacturing costs are reduced measurably, and the purchaser can selectively buy any particular type of ice skate and roller skate combination, or for that matter, a full or partial set of ice and roller skates, as desired.

. Still another object is .to so form the device that when the ice or roller skate attachment is connected to the shoe, there will be no interference with proper skating movements, and no tendency of the attachment to become loosened or wholly separated. from the shoe. 7

. For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings,

gangsta a 2 and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a side elevational view of a device according to the present invention, in which an ice skate attachment has been connected to the shoe, ready for use.

Fig. 9 is a View similar to Fig. 8 in which the ice skate attachment has been connected to the shoe by a modified type of locking device. t

Fig. 10 is a sectional view substantially on line ltl1tl of Fig. 9. i

Fig. 11 is a view similar to Fig. 9 showing the attachment at an intermediate step of connecting the same to the shoe, the locking means being illustrated in exploded relation to the remaining components of the'device, portions being broken away and other portions being shown in section.

A single pair of shoes is used with both the ice and roller skate attachments. The shoe, generally designated 10, includes a reinforced upper 12, connected to a sole A rectangular front support or connecting plate 16, formed from a single piece of rigid, metal material, is permanently and fixedly attached to the underside of the toe portion of sole 14, by means of rivets 18 or their equivalents, uniformly spaced along the longitudinal medianof the sole. The rivets pass through correspondingly spaced openings 2d of plate lid (see Fig. 7).

The dimensions of the plate to, and also of the other components to be described hereinafter, will of course be varied according to the size of the particular shoeon which the device is to be mounted, that is, a smaller plate 16 might be used for childrens shoes, with a larger one being used for adults shoes. in any event, integrally formed upon the opposite longitudinal edges of the plate 16 are downwardly and inwardly turned guideflanges 22, said flanges being comparatively wide as shown in Figs. 2 and 5 and extending the full length of plate 16. At the forward extremity of plate 16, there is integrally formed aligned longitudinally with the front connecting plate 16 (Fig. 5). integrally formed upon opposite longitudinal edges of plate 26 (see Fig. 6) are guide flanges 30 corresponding to and aligned with flanges 22. Intermediate its ends, plate 26 is integral at opposite sides thereof with depending, fiat ears 32, said ears being for the purpose of receiving a locking means, to be described hereinafter. The ears interrupt the continuity of the guide flanges 30 along each side of the plate 26, as shown in Fig. 5, but do not interfere with the adaptability of the flanges 30 components shown in Fig. 1.

or otherwise fixedly secured at their upper ends to the underside of an elongated; rectangular, planiform attachmerit plate 44. g

It will be readily seen that in attaching the ice skate attachment 3 5 to the shoe, one shifts the attachment 34 from the right in Fig. 1, guiding the forward extremity of the plate 44- into the rear ends of the guide flanges 30. Then, the attachment 34- is moved to the left in Fig. 1, with the side portions of the plate 44- sliding in the flanges 3t) and ultimately engaging and sliding, in the flanges 22. Eventually, the front end of the plate 44 will abut the stop or abutment plate 24, in the relative position of the Referring now to Fig. 4,,to lock the shoe and the attachment against relative movement, there is provided an opening 46 in leg 4-}. Opening 46 is transversely aligned in the use position of the parts with openings 48 formed in ears 32, to receivea lock pin 50 inserted from the left in Fig. 4- and having a head 52'engageable. with one car 37.. The other end of pin 56 projects beyond the opposite car 32, and has an opening adapted to receive a cotter pin 54 which bears against said other car 32.

It will be seen that in this way, the skate attachment 34 is releasably but fixedly interlocked with the con: necting means 16, 26 of shoe 10.

As previously noted, the skate attachment 34 can be of any desired type, and could be so designed as to provide a racing type ice skate, figure skate, hockey skate, etc. Any of these types could be purchased by a user for attachment to'the shoe 10, and in no event is it necessary to modify the shoe It) or the attaching means 16,

26 carried thereby to receive a particular type of ice skate attachment 34.

Referring now to Fig. 8, there is here shown a roller skate attachment generally designated 56, usable interchangeably with the ice skate attachment 34. Again, the roller skates could be of any desired type, and could be indoor or outdoor roller skates, racing skates, etc. Thus,

the roller skate attachment has the front and rear wheel hangers 58, 60 carrying wheels or rollers 62. The hangers are fixedly secured to the underside of an attachment plate 64 identical to the plate 454, with the roller skate attachment being connectible to and disconnectible from the connecting means 16, 26 of shoe It) in the same manner as the ice skate attachment 34.

in Figs. 9-11, a modified type of locking means is used in place of the locking shaft or pin 50. Otherwise, the construction is identical to that of the first form of the invention.

Thus, secured to the shoe 1%) is a connecting plate 16 identical in all respects to the plate 16 of the first form of the invention. A rear connecting plate 26 is identical in all respects to plate 26, except for omission of the cars 32, thus providing continuous guide flanges 30 along opposite sides of plate 26*.

In Figs. 9-11, an ice skate attachment 34 has been shown connected to the shoe 10. However, it will be understood that the modified locking means is of course usable with equal facility with a roller skate attachment such as shown in Fig. 8.

r 4 .6 s a a 9 the. d anc between. said, p tes 6., .6.:-

A locking screw 68 has a knurled head, and formed in the locking plate 66 and. in the attachment plate 44* are registering openings 72, 70, respectively. Opening '70 is threaded, while opening 72 is smooth-walled.

The attachment 34 is slid into place in the same manner as in the first form of the invention. This will be noted from Fig. 11, in which the attachment 34 is shown partly. moved. into. its operative position.

When the attachment 34E abuts the stop flange 24, the locking plate 66 is merely positioned against the underside of the plate 44?, abutting at its forward and leading edges against the, guide. flanges 22, 30 respectively.

The openings 70, 72' will be in registration at this time and screw 68 is extended upwardly through opening 72 and threadedly engaged in opening 70. This fixedly connects the plate 66 to the plate 44*, and it willbe readily observed that the plate 66 will now constitute an abutment engaging boththe plates 16 and 26 to prevent relative movement of the-attachment 34 and the shoe to which it is secured.

To disconnect the attachment, it is merely necessary to back the screw. 68 out of the opening '70.

In both forms of the invention, the device is characterized by the ease with which conversion is effected beembodiments of my invention, it is to be understood that I do. not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

A skate construction comprising support means attachable to the foot of a user, a skate attachment removably. connectible with the support means, and interlocking means releasably interengaging the support means and skate attachment against relative movement in the connected relationship thereof said supporting means including a shoe and spaced support plates fixedly con nected to the sole of the shoe, the forward supporting plate extending to the front of the shoe, the skate at tachment including an elongated attaching plate extending substantially the length of the attachment and being interengageable with the spaced plates of the support means and a supporting-surface-engaging means depending from the attaching plate, said spaced plates of the support means being formed'with longitudinally extendposite longitudinal portions of the attaching plate to effect the engagement of the attaching plate'with said spaced plates, said plates of the support means being spaced apart longitudinally of the shoe, the forward one of the spaced plates including at its front extremity'an' abutment flange engaging the attaching plate on the sliding of the attaching plate'to a use'position, to limit movement of the attaching plate beyond said use position,

said spaced plates including guide flanges on the under side thereof in confronting. relation, the attaching plate being slidably engageable with the guide flanges, the attaching plate'having an'opening, said interlocking means comprising a locking plate having an opening registering with that of the attaching plate and abutting the respec- 1 tive guide flanges in the space between said plates of the support means, said lock means further including a screw engageable in the registering openings of the locking plate and attaching plate to removably, fixedly connect the locking plate to the attaching plate.
