UNITED STATES PATENT OFFICE.

WILLIAM H. \VATERMAN, OF PROVIDENCE, RHODE ISLAND.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 336,607, dated February 23, 1886.

Application filed June 26, 1885. Serial No. l69,805. (No model.)

T or whom it may concern:

Be it known that I, WILLIAM H. WATER- MAN, of Providence, in the State of Rhode Island, have made certain new and useful Improvements in Sewing-Machines; and I do hereby declare that the following specification,

taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a top view of a portion of the shuttlebox. Fig. 2 is a section on linezvm. Fig. 3 is a View of the bottom of the shuttleboX. Figs. 4 and 5 are side and top Views, respectively, of the shuttle. Fig. 6 is a view of the shuttle-pinion.

My invention is more particularly designed for and adapted to a machine for sewing leather, known in the market as the What Cheer sewingnnachine, which is provided with a horizontal box, within which at one end is located the shuttle device, which is operated by suitable pinions, to which motion is communicated by means of acam through a reciprocating rack engaging therewith.

The object of my invention is to so construct the parts that greater durabil ty in the machine itself will be secured, together with a more perfect and satisfactory operation; and it consists in the manner of strengthening and securing the shuttle pinion, hereinafter described.

In the drawings, A is the shuttle-box; B, the shuttle; WV, the shuttle-carrier; G, the carrier-pinion; D, a larger pinion which engages with the carrier-pinion G and the rack E upon the end of the reciprocating rod or bar F, the latter being operated by a suitable cam.

The shuttle-carrier W has a stud, G, around which the smaller pinion, O, is secured. The manner of securing the pinion G to the stud G has heretofore been to enlarge the diameter of the hole in the former upon one side and force in a wedge, screw, or spline, which would prevent any rotation upon the latter. The enlargement of such diameter, as described, so weakens the pinion that it often breaks and stops the machine until a new pinion can be procured and adjusted. If, however, the pinion does not break, it frequently becomes loose, which renders the machine faulty in its operation and prevents it from doing good work.

In my invention I construct the pinion C with a vertical collar, H, both of which sur' round the stud G, and are secured thereto by a pin or rivet passing through the collar and entering the stud, as will be readily understood. It will now be seen that the pinion G will be strengthened instead of weakened, and that, attached in the manner described, it will be impossible for it to work looseand affect the operation of the machine.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a sewing-machine, as described, the combination, with the shuttle-box A, having seats or depressions for the gears and a longitudinal groove for the rack-bar, of said rack-bar working in said groove, shuttle-holder WV, having an extended stud, G, Jinion O, lying in the depression in box A, and having an extended collar, H, fitting over stud G and extending out past the surface of box A, where it is secured upon said stud, and the idler gear or pinion D, connecting rack E and pinion C, also lying in the depression in box A, substantially as set forth.
