ATTACHMENT FOR SEWING-MACHINES.

To all whom it may concern:

Be it known that I, MARY MOCABE, a citizen of the United Statesfresid'ingat New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Attachments.

for Sewing-Machines; and I do hereby*declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments for sewing machines and more particularly to that class of portable machines operated by hand and my object is to provide a support for the hand sewing'machine.

A further object is to provide means for operating the machine by foot power and a further object is to provide means for folding the support and power applying mechanism, whereby when stored away it .will occupy a minimum amount ofspace.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claim.

In the accompanying drawings forming part of this application, Figure 'l is a front elevation of my improved supporting de vice, and, Fig. 2 is an'edge elevation thereof.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a frame which is preferably made in sections 2 and 3, the meeting ends of said sections having brace bars 4: and 5, which are secured together by means of hinges 6, so that when desired, the section 3 may be folded down against one face ofthe section 2 and in order to retain the section 3 in its extended position, a pin 7' is introduced through sockets '8 and 9 on the section3 and similar sockets 10 and'll on the section 2, the sockets 8 and 11 being attached to vertical brace bars 12 and 13 on the sections 3 and 2, respectively, while the sockets 9 and 10 are attached to the brace bars 5 and 1, respectively. 1

Rotatably mounted at the upper end of the section 3 is a belt wheel 14, which is 1'0- tatably mounted on a stub shaft 15, saidwheel being provided with a socket 15 into which the end of the handle employed in connection with the hand operated machine is to extend and "as said socket is eccentrically mounted, the rotation of the wheelwill edge of'the section 3 adjacent the is provided with a guard 27, which is adapt- Specification of Letters Patent.

operate the machine, the same as when the machine is operated by hand.

A belt 16 passes and around a driving wheel'17, which-is rotatably mounted on the vertical bracebar 13 of the section 2, said wheel having a around the belt wheel 14 crank shaft 18, to the-,gcrank portion of which is attached a pitman 19, the lower end of said pitman being hingedly secured to a foot treadle 20 and by means of which power is'applied to the driving wheel 17.

The treadle 20 is mounted upon 21, one end of which is attached to the sec tion 2 by means of a hinge 22, while the tapposite end thereof is, mounted in a support 23 and it will be readily seen that when the device is not in use, the shaft 21 and 'treadle mounted thereon may be swung upwardly and placed in alinement with the'face of the section 2 after the withdrawal of the usual connecting pin between the treadle and the pitm an 19.

Hingedly secured adjacent the upper end of the section 3 is a platform 24:, upon which the machine is adapted to rest, said platform being held in its elevated. position by meansof'a brace arm 25, one end of which is hingedly secured to the lower face of the "platform, while the opposite .nd thereof is adapted to engage a lug 26 on the brace bar 12, said arm and lug being so arranged as to holdthe platform in a horizontal position when the arm is engaged with the lug. One wheel 17 ed to ,keep the garments or articles being sewed from coinin'gin contact with the driving wheel and belt, one section of the uard also-having'an ear 28 thereon, which 'orms a support for one end .of'the crank shaft 18.

In operation the section 2 of the frame 1 is raised to a vertical position and the shaft 21 then. lowered to a horizontal position or uhtil the support 23 at the outer end thereof engages the floor, the shaft 21 being held in this position by any suitable means, such as a curved arm 29, the freeend of which is to be swung into engagement with the brace bar 13 when the shaft is' in its lowered position and the section 3 is then swung upwardly and the pin 7 introduced through its respective sockets, thereby. holding the sec tion 3 in alinement with the section 2. The platform 24; is then raised to a horizontal position and the arm 25 placed in engage- .ment with the lug 26, when the machine may be placed on the platform and attached to the socket In order to prevent the machine from being turned backward, ratchet .30 is'fixed to the wheel 17 and with said ratchet coiiperates a latch 31, which latch is prererably located upon the brace bar 13 and in position cooperate with the ratchet 30 and hold the wheel against reverse rotation, 7

It will thus be seen that 1 have provided a convenient support for the machine and means for applying foot power thereto and I one that will occupy but a minimum amount of space when in use, and further that when the sewing operation is completed, the frame and operating parts may be compactl fold-- ed together and readily transporte from lace to place or stored awe the wei ht V ands ize tifthe frame being such as to permit of transbortation in a suitcase or similar object if desired, and it will be readily apparent that the frame may be quickly set up for use or folded together for transportation. 7

What I-claim is: In a combined supporting and power appll ying mechanism, the combination with a ame formed in sect1ons,sa1d sections being hlngedly secured together and a securing dey vice adapted to hold said sections in vertical alinement; of a shaft hingedly mounted ad- 'jacent the lower portion of said frame, means to normally hold said shaft extended at right angles to the frame, a support for the'outer end of the shaft, a treadle mounted on the shaft, a driving Wheel rotatably mounted on the frame, a crank shaft for the wheel, a pitman connecting the driving treadle with the crank shaft, a belt wheel at the upper end of the frame, a belt extending In testimony whereof I have signed my name to thisspecification-in the presence of two subscribing witnesses.
