SPECIFICATION' forming pari: o Letters Patent N o. 380,029, dated March 27, 1888.
Application filed December 2, 1887. Serial No. 256,823. (No model.)
- full, clear, and exact description yof the inven- 1 tion, such as will enable others skilled in the art to which it appertains to make and usethe same. A
lVIy invention relates to certain new and useful Improvements in swinging treadles for sew- Ing-machines or other mechanism requiring power.
It consists of a swinging lever adjustably connected to one or more swinging arms, that are in turn connected to a crank-arm of a revolving shaft or to a crank-pin on drive-wheel,
or connected in any other suitable manner to mechanism to which it is desirable to impart motion.
The object of my invention is to impart motion to machines by means of a swinging footlever, one or more swinging arms, and suitable connections. I attainthis object by means of the peculiar construction and arrangement of the various parts of my device, which will be more fully pointed ont and described in the specification and claim, reference being had to the drawings accompanying this application and forming part of the same, in which- Figure 1 is a View of my invention taken from the end of the sewing-machine. Fig. 2 is a front elevation, and Figs. 3 and 4 are detail views.
Similar letters refer to like parts throughout the drawings.
Referring to the drawings, A represents a sewing-machine frame, and B the bed or table.
C represents the drive-wheel, and D the belt.
which connects with sewing-machine. (N ot shown.) Metal plates E and E are formed with inwardlyinclined end projections, a, adapted to fit tightly the edges of table B. Their opposite ends are formed with right-angular projecting lugs b, having perforations b', through which is passed a screw-bolt, c, and by means of which said plates are drawn tightly against the edges of table B, and are thus held rigidly in place to the under face of said table. Near the end of plate E a projecting ear or lug, d, is secured to its under face. Said lug is provided with a perforation, d', to receive pivot-holte. A swing-arm, F, is pivoted to lug d by bolt e and projects downward, and 'its lower end is perforated to receive bolt f. The upper portion of said arm is provided with a slot, g, adapted to receive a set-screw bolt, h. The lower end of arm F is pivoted to one end of pitman-rod G, andthe opposite end of said rod G is perforated to receive crank-pin z', which is formed on crank-arm H, that is secured to shaft H', on which is secured` drivewheel C. Y
Plate E is formed'with a dovetail-shaped slot, j, extending inward from its outerend, said slot being adapted to` receive and hold loosely an ear-piece, 7c, which is formed with an extension, k', having a perforation to receive a thumb screw bolt, k2, by means of which said earpiece may be held at any desired position within the slotj. A perforation is formed in the ear-piece k, and a bolt, Z, is inserted, to which the lever I is connected at one end, and the opposite end is provided with a footpiece, J.
' The upper end of lever I is slotted to receive l set-screw m, to which is pivoted one end ofthe connecting-rod K, and the opposite end of said rod is perforated to receive screw-bolt h. The center of said connecting-rod K is formed with holes n and made to lap over, and is held by set-screw o, that passes through said holes when they register, the purpose being to lengthen or shorten said rod K when desired to conform to the change of the position of the ear k, holding the end of lever I, as shown in Fig. 1. A similar construction is used when tw levers are 'connected to the ears k, as shown in Fig. 2, the foot-piece J extending across and joining the lower end of each of said levers. v
In the detailview, Fig. 3, the inclined groov or slot j is shown, and Fig. 4 represents the beveled edges of the ear-piece 7c. This conpower to operate.
i struction herein described, though shown and IOO rfhe operation of my device is obvious and pivoted at `one end to the free end of said needs no description. f swing-arm and its opposite end to a crank-pin,
Having thus described my invention, what I and a foot-board on the free end of said lever, claim, and desire to secure by Letters Patent, substantially as set forth.
