WLADYSLAW NIGBOROWICZ, OF GALLITZIN, PENNSYLVANIA.

MULTIPLE-SOCKET WRENCH.

To all whom it may concern:

Be it known that I, WLADYsLAW NIGBoRowIoz, a subject of the Emperor of Austria- Hungary, residing at, Gallitzin, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Multiple-Socket Wrenches, of which the following is a specification.

This invention relates to certain newand useful improvements in multiple socket wrench. 1

The primary object of the invention is to provide a ratcheting socket wrench that is readily reversible and easily adjusted for the accommodation of turn nuts of different versible socket wrench having an operating ratchet handle and provided with a plurality of different-sized receiving sockets selectively positionable for individual use and projectingly positioned when desired for operation. 7

A still further object isto provide amain socket wrench of the ratchet type carrying a plurality of telescoping socket members of graduated sizes, such socket members being preferably projected whenever the wrench is desired for use.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrange-.

ment of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a partof this application and in which like designating characters refer to corresponding parts throughout the several views ;F igure 1 is a face view of the device with the handle partially broken away and with parts shown in longitudinal section. elevation thereof. Fig. 3 is a perspective sectional view taken upon line IIIIII of Fig.2. Fig. 1 is a side elevation of the socket members removed from the device and in their projected positions, and Fig. 5

is a similar View of a different side of the same.

mediate threaded perforations 17 are-pro'-' vided therein at points adjacent its opposite end faces 18. A ratcheting pawl or 'dog 19 11 by means of a-transverse pin 21 and carries inwardly projecting teeth 22which are normally maintained within the path of travel of the outersurface ofthe hub 15 and ratchetingly' engageable with the grooves 16' by'means of a helical expansion spring 22 maintained within the socket 20 and in constant engagement with the heel 23 of the said pawl. By this'arrangement it will be seen that thehub 15 may be readily turned in one direction by means of the handle 11, while any resistance exerted upon the hub will allow the handle to ratchet thereover in its return movement, the inclined faces 24 of the pawl teeth 22 freely slipping over the edges of the said grooves 16 during. such forcible movement of the handle. I r

The hub 15 is provided with an axial opening 25 extending therethrough and forming a nut-receiving socket, the said opening being of any deslred shape and cor responding with the shape 'ofthe nut to be is'pivoted within asocket 20 of the handle i operated upon and herein illustrated as hexagonal in form. .A wrench sleeve 26' is slidably positioned being also hexagonal in form withinthe said hub opening 25 and is provided with a nut-receiving hexagonal opening 27 extending axially therethrough and being of less "dimensions than the huo Similarly, a second wrenchopening 25. v sleeve 28 is slidably mounted within .the afore-mentioned sleeve 26 and has a hexagonal nut-receiving opening 29 therethrough and in this opening an innermost wrench sleeve 30 is slidably positioned having a relatively small nut-receiving opening 31 I therein which is thereby arranged centrally of the hub 15. I j

The hub opening '25 is provided with a longitudinal groove 32 therein adapted to slidingly receive a longitudinal rib 33, while the sleeves 28 and 30 are provided with similar ribs 34 and 35 respectively adapted for sliding reception within corresponding grooves 86 and 37 respectively, of the sleeves 26 and 28. By reason of the hexagonalshape of the separate sleeves 26, 28 and 30 as well as the receiving hub opening 25 and the guiding lugs 38, 34k and 35 it will be seen that while the wrench sleeves and hub are relatively slidably positioned, all relative rotation between any of the said members is positively prevented.

A means is provided for the prevention of a separation of the hub 15 and the several wrench-sleeves which consists of interengaging screws and grooves, it being noted that the screw 38 is carried by the hub 15, being positioned within one of the grooves 16 thereof and freely extending within a longitudinal valley, 39 of the hub-carried sleeve 26 and while a similar screw 40 is carried by the sleeve 26 and extends within a valley 4C1 of the sleeve 28 and similarly, a screw 42 carried by the sleeve 28 extends within a valley 4:3 of the inner sleeve 31.

It will be thus evident that while the sev eral sleeves may be projected as illustrated in rigs. 4i and 5 the same will be retained from being disassembled from the hub 15 and it will be also seen that the hub opening 25 may operatively engage a turn nut when the sleeves 26, 28 and 30 are moved inwardly of either end of the hub opening, while the sleeve 26 may be readily adjusted by being projected for the reception of a nut within its socket opening 27, it being under stood that the sleeves 28, and 30 will then be allowed to, remain in substantially their normal closed position within the hub 15.

lso, the sleeves 26 and 28 may be projected and the sleeve 30 positioned inwardly of the sleeve opening 29 when desired to use the said opening 29 as a socket for receiving the nut, while of course, the central opening 31 may be operatively employed by projecting the inner sleeve 31 to its extreme outward position as illustrated in, Figs. 4 and 5 of the drawings, or in intermediate projected positions or even in its normal inclosed position within the hub as illustrated in Fig. 1.

When desired to look all of the sleeves in position within the hub 15, a set screw 14 maybe employed threaded within one of the hub openings 17 and passing through a similar opening d5 of the sleeve 26 and 16 of the sleeve 28 and bear within a socket 4:7

and at which time however the inner sleeve 30 will be freely positionable.

It will be evident that many different combinations of relative positions of the wrench sleeves may be arranged for adapting the device for use in connection with different sized nuts and for engagement at different sides of the wrench, it being seen that the Wrench hub 15 may be turned in opposite directions by using a reverse one of the hub faces 18 for engaging the nut, although the ratcheting pawl 19 allows the handle 11 to actuate the hub in a uniform direction. It will be also noted that a finger-hold 51 is provided upon the heel 23 of the pawl 19 whereby the teeth 22 of the pawl may be readily released from the groove 16 of the hub, and the hub thereby readily removed from the collar 10.

VVhile the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is l. A ratchet wrench comprising a hub having an engaging opening extending therethrough, a plurality of double-ended nut-receiving sleeves telescopingly adjustably positioned within the said opening, cooperating rotation preventing means carried by the sleeves, and means for locking he sleeves in extended and retracted adjusted positions.

7 2. A ratchet wrench comprising a collar, a cylindrical hub journale'd therein and having an angular nut-receiving opening therethrough, a plurality of telescoping Wrenchsleeves of similar configuration slidably positioned within the said opening, cooperatmg tongues and grooves formed on the opposed faces of the sleeves, and means for locking the sleeves in extended and retracted adjusted positions.

8. A ratchet wrench comprising a cylindrical hub, having a nut-receiving hexagonal opening axially extending therethrough and having spaced longitudinal grooves upon its outer surface, a sleeve encircling the said hub and removably positioned thereon, a spring-pressed releasing and ratcheting pawl attached to the said sleeve and in operative engagement with the said grooves, a plurality of telescoping wrench-sleeves slidably positioned within the saidhub opening and being each formed hexagonal in cross-section, guide tongues and grooves carried by the opposed faces of each sleeve, and means for locking the sleeves in eXtended and retracted adjusted positions.

a. A ratchet Wrench comprising a cylindrical hub, having a nut-receiving hexagonal opening axially extending therethrough and having spaced longitudinal grooves upon its outer surface, a sleeve encircling the said hub and removably positioned thereon, a spring-pressed releasing and ratcheting pawl attached to the said sleeve and in operative engagement with the said grooves, a plurality of telescoping wrench-sleeves slidably positioned within 10 the said hub opening and being each formed hexagonal in cross-section, longitudinal lug justable locking means between the sleeves 15 whereby the hub and sleeves may be locked in any adjusted position.

In testimony whereof I afiix my signature.
