FOOT-GOVERNING DEVICE Application filed July 14, 1924. Serial, No. 725,817.

To all whom it may concern:

Be it known that Monnrs EPSTEIN, subject of the Government of Russia, residing at New York city, in the county of New York and State of New York, has invented certain new and useful Improvements in F oot- Governing Devices for. Sewing and Embroidering Machines Having Universal F eed- Motion, of which the following is a specification.

This invention relates to sewing andembroidering machines, and more particularly to machines of this character operating with universal feed-motion and in which the feed is governed by means of a crank handle positioned on the under side of the machine table top.

The general practice ofoperating powerdriven machines of the character described is to conduct the crank handle for governing the feed with the right hand, to guide the material with the left hand, and to control the driving of the machine with one or both feet, the feet thus remaining comparatively idle while the hands bear the brunt of the work.

An object of the present invention is the provision of a device which shall enable the operator to controlthedriving of the machine with one foot, and to conduct the movement of the crank-handle governing the feed-motion with the other foot-so as to leave both hands free to guide the material.

Another object of the invention is the provision of a device of the character describedv comprising few and simple parts,

which may be readily attached to any sew-' ing or embroidering machine having a universal feed-motion governed by a crank handle, which is comparatively inexpensive to manufacture and which serves to improve the efficiency of the control and operation of the machine to a high degree.

Other objects of this invention will in part. .be obvious and in part hereinafter pointed out; y i

The invention accordingly-consists in'the features-of construction, combinations of ele ments and arrangement of parts which will be exemplified in the construction hereinafter described and of which'the scope of ap plication will be indicated inthe following claims. 7 V

In the accompanying drawing, in which is shown oneof the various possible illustrative embodiments of this invention,

Fig. 1 is a front elevational view showing in outline a machine of the character described, a motor drive and control therefor, and adevice embodying the invention applied thereto;

Fig. 2 is a plan View of the stirrup guide plate; T

Fig. 3 is a sectional view taken on line 33 of Fig. 2;

Fig. 4 is a front elevational view of the stirrup and swivel mounting therefor; and

Fig. 5 is a view partly .in section of a modified form of a foot control device.

Referring in detailto the drawing, 10 denotes a sewing or embroidering machine having a universal feed-motion governed by a crank handle 11, said machine being of any standard make such as described in Patent No. 148,182 to E. Cornely, dated March 3, 1874. The machine 10 as seen in Fig. 1 is mounted on a top 12 of a con ventional sewing machine stand 12, the crank handle 11 for controlling the feed-motion being positioned on the under side of the top 12 as is the general practice. For simplicity, machine 10 is shown to be driven by an individualmotor equipment 13,.the speed and operation of which is controlled by pressure on foot treadle 14 in the usual manner. It is to be understood that in case of group drive, which is quite com-v mon', the motor equipment 13 maybe replaced by any form of clutch-control driving device installed in the well known man ner;

A device for conducting the crank handle 11' governing the feed-motion by the foot instead of by the hand is designated as a whole in 1 at 15, and comprises a downwardly extending rod 16 which replaces the usual handle portion of crank handle 11, a stirrup 17 mounted on the lower end of rod 16, and guide plate 18 for engaging with downwardly projecting portion'17 of stirrup 17 I The ends of rod 16 are preferably threaded to permit the proper adjustment of the rod 16 with stirrup 17 between crank handle 11 and plate 18, and said rod 16 may be rigidly'secured to the upper end of the crank handle 11 by the lock nuts 19, as shown in Fig. 1. The stirrup 17 may be swivelly mounted in any suitable manner at the lower end of the rod 16 and preferably has an anti-friction mounting 17 as shown in Fig. 4, the upper portion of said mounting being fixedly secured to rod 16 by any suitable means as for example by a lock nut 20.

' The guide plate 18, as shown in Figs. 2 and 3, is formed of an inner circular disc 21 and an outer annular disc 22 fitting therearound, there being a circular raceway 23 having a groove 23 extending upwardly to the outer surface of plate 18 formed between said discs 21 and 22. Holes 21 and 22 formed in discs 21 and 22 respectively provide means for fastening guide plate 18 in position on the floor under the machine.

The projecting portion 17 of the stirrup is adapted to extend down into the groove 23 and is provided with a ball end 17 to restrict the movement of the stirrup 17 to the path of the raceway 23.

The operation of device 16 is quite simple and as seen from Fig. 1, the left foot of the operator by pressure of treadle 14 controls the drive and speed of the machine 10, the right foot inserted in stirrup 17 governs the movement of universal feed-motion through crank-handle 11 and both hands of the operator are left free to guide the material being worked on.

If desired, by simply interchanging the relative position of treadle 14 and stirrup 17, the machine may be arranged to'have the machine drive controlled by the right foot and device 15 by the left.

In Fig. 5 is shown a modified form of guiding connection for the lower end of stirrup 17 comprising a plate 2 1 on whch a crank arm 25 is pivotally mounted prefer- V ably in a ball bearing 26. The outer free end of said arm 25 engages with a suitable downwardly extending stud 17 and is arranged to guide the stirrup 17 in a circular path corresponding to the crank handle 11.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is Well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and notin a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent i 1. In combination, a sewing or embroidering machine having a universal feed motion and a device having foot receiving means adapted to move in a circular path for governing the feed motion.
