GEORGE T. REED, OF BALTIMORE, MARYLAND, ASSIGNOR TO JOHN B. H. JEFFERSON AND VICTOR H. KLINEFELTER, BOTH OF SAME PLACE.

HAND DRIVING MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 431,994, dated July 8, 1890.

Application filed March 14, 1890. Serial No. 343,827. (No model.) I

1'0 all whom it may concern.-

Be it known that I, GEORGE T. REED, of the city of Baltimore, in the State of Maryland, have invented certain Improvements in Hand Driving Mechanisms for Sewing and other Machines,of which the followingis a specification.

This invention relates to an improved attachment to a sewing-machinewhereby the same may be driven by hand-power without interfering with the treadle mechanism, as

' will hereinafter fully appear.

In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which Figure 1 is a side elevation of a sewing-machine table, the fly-wheel, and the treadle mechanism, together with the improved handpower attachment. Figs. 2 to 11, inclusive, are details of the invention on an enlarged scale.

Similarletters of reference indicate similar parts in all the views.

In the said drawings, A represents the top of the table, and B the legs thereof.

C is the fly-whecl, having the crank-pin a, and D the treadle. The pitman which con- 'nects the trcadle with the crank-pin is denoted by E.

The above-described parts embody no part of the present invention.

F is a hanger secured by means of screws (not shown) to the under side of the table A. G is a lever fulcrumed to the hanger F at Z).

H is a connecting-rod pivoted at one end to the lever G and at the other hinged to a clamp I adapted for attachment to the head of the pitman E. The connecting-rod II is in two parts 0 and (Z, fastened together by means of a set-screw e. The part chas a threaded hole to receive the set-screw e, and the other d is slotted, as shown, and fitted with projections f between which the part c fits. These projections are shown in Figs. 7, 8, and 9, which are respectively a front view, a side view, and a cross-section of the connecting-rod. IVith the above-deseribed construction of the connecting-rod H it is evident that it may be lengthened or shortened to suit the machine to which the invention is to be applied, and also to change the angle of the lever G. The outer or front end of the lever G is made short in order that when the machine is to be run by means of the treadle D it will not be in the way of the operator; but when the machine is to be driven by hand-power the arm of the lever is lengthened by means of a handle J, which is inserted sidewise in a socket g in which the said arm terminates. The front face of the handle is notched at h to receive the cross-bar t' of the socket, and thereby prevent its withdrawal endwise, and its removal from the socket laterally is prevented by means of the button One jaw of the clamp I is furnished with teeth 7; and the other with a set-screw m, all of which form slight depressions in the head of the pitinan, which is made of wood.

The handle J is operated by the right hand of the operator, who guides the work with the left.

I claim as my invention In combination with the table A and the head of the pitman E, the hanger F, lever G, with its socket extensible connecting-rod H, clamp I, and removable handle J, substantially as and for the purpose specified.

GEORGE T. REED.
