Application lcd June 27, 1900. Serial No. 21,829. (No model.)

To all 107mm/ '7T/ riz/(ty concern.'

lle it known thatl, LEOPOLD BERGER@ citizen ofthe United Astates, residing' at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Motors, of which the following;` is a specification.

'lhis invention relates to new and useful iinprovenients in foot-motors; and its primary object is to provide a device of this character especially adapted for use on sewing-machines and similar machines which are propelled oy foot-power and whereby the inotion of the foot reduced to the minimum.

To this end the invention consists `in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showingl the preferred form of my invention, and in which- Figure l is a front elevation thereof. Fig. is a side elevation, Fig. 3 is a plan View of the treadle and its supports. Fig. 1L is a Yfront elevation of a modified forni of the device. Fig'. 5 is a section therethrough, and Fig. (i is a plan view of the treadle and its support.

teferrinp; to said ligures by numerals of reference, I l are standards connected by a suitable top 2,'from which are suspended. hangers 3, Within which is iournaled a shaft 4I, having a weighted. ivlieci or pulley 6 secured thereto and also provided with a double crank 7, as shown. Itods S extend downward from the top and are secured at their lower ends to a strip 9, connected at each end by Wires or rods IO with the adjacent standards l. These rods may be provided with suitable tighteiiling ineanruas the turn-knuckles II. A treadle l2 is journaled upon the strip 9 and is provided with an eye I3 at each side of its bearing. Within each eye is mounted the end of a rod le, which extends upward to one of the cranks 7, an shown.

In Figs. 4, 5, and l I have shown a modified form of device in which the strip I5 is journaled in boxes lo, to which the brace-wires IO are fastened. fluitable collars, as 17, are secured to the strip I5 to prevent lateral movement thereof. arms 18 are secured to and extend outward from the strip l5,and a treadle 19 is suspended therefrom by means of pivoted hangers or brackets 20. One of these arms extends to the rear of the strip and is secured to the cranks 7 in a manner similar to treadle I2. A strip, as 2l, is connected to the standards l, and a treadle 22 is journaled thereon, as shown, said treadle being pro vided with a flange23 upon its upper surface, as shown.

rllhe operation of the device disclosed in Figs. l, 2, and 3 will be readily understood. By bearing,r upon the treadle l2 the two cranks 7 will receive power through the rods le, and the weight upon the Wheel will give a steady movement thereto and overcome all deadcenters.

In the construction shown in the modication the heel of the foot is placed on treadle 22 and the front of the foot upon treadle 19, thereby permitting' an easy movement of the foot with the utilization of the minimum amount of power.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without dcpartiugo)` from the spirit or sacriiicing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination With standards and a top connecting.,r the saine; of a double crankhinge hung from said top; a strip suspended therefrom; brace-rods connecting'the strip and standards; a pivoted lever upon the strip; and rods secured to the lever at opposite sides of its pivot and to the cranks.

2. The combination with standards and a top; of a double crank suspended from said top; strips; Wires supporting said strips from the top; brace-wires connectingthe strips and standards; pivoted levers upon the strips; rods secured to one of the levers at opposite sides of its pivot and to the cranks; and a treadle suspended between and from said levers.

3. The combination with standards and a IOO top; of a double crank suspended from the top; strips; hanging rods connecting said strips With the top; braces Connecting the strips and standards pivoted levers upon the strips; rods connected to the cranks; and to one of the levers at opposite sides of its pivot; a treadle pivotally supported from said le- Vers; a second strip secured to the standards;

and a treadle mounted upon said strips adjan cent to the treadle of the levers. 1o

In testimony whereof I affix my signature in presence of two Wit-messes.
