UNITED STATES PATENT OFFICE.

JOSEPH V. MORTON, OF WINCHESTER. KENTUCKY.

SEWING-MACHINE MOTOR.

SPECIFICATION forming part of Letters Patent No. 225.627, dated March 16, 1880.

Application filed January 14, 1880.

To all whom it may concern Be it known that I, J OSEPH V. MORTON, of Winchester, in the county of Clarke and State of Kentucky, have invented a new and useful Improvement in Sewing-Machine Motors, of which the following is a specification.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sectional side elevation taken through the line a," m, Fig. 1. Fig. 3 is a side elevation, partly in section, of the jointed hand-lever.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish sewing-machine motors so constructed that sewing-machines may be driven by handpower or by foot-power, or by both handpower and foot-power, as desired.

The invention consists in the combination, with the sewing-machine treadle, of a handlever, a pivoted connecting'rod, and an adjustable clamping-rod, so that hand-power can be applied, in connection with the treadle, to drive the machine, and also in providing the hand-lever with a jointed hand-piece and a spring catch-bolt, so that the hand-piece can be turned down out of the way when not in use, as will be hereinafter fully described.

A represents an ordinary sewing-machine table. Bis the drivingpulley, which is designed to be made heavy, so as to serve also as a fly-wheel, and to which is pivoted the upper end of the pitman O, in the usual way. The lower end of the pitman O is pivoted to the treadle D, which is pivoted to the side frames of the table A.

As thus far described there is nothing new in the construction.

To the lower side of the table-top is attached a stud, E, the lower end of which is slotted to receive the lever F. The lever F is pivoted in place by two set-screws, G, which pass in through the jaws of the stud E, and the conical ends of which rest against the opposite sides of the lever F.

To the forward end of the lever F is pivot ed the upper end of a connecting-rod, H, the lower end of which is pivoted to the forward end of the rod I. The rod I passes through holes in the upper ends of two studs, J, attached to the treadle D, where it is secured in place by one or more set-screws, K, passing in through one or both the studs J, and pressing againstthe rod I, so that by loosening the set screw or screws K- the clampingrod I may be adjusted to regulate the leverage, as required.

With this construction the pulleyB may be rotated to drive the sewing-machine by operating the lever F by hand, so that the machine may be driven by hand and foot power alternately, if desired, or exclusively by handpower or by foot-power.

With this construction, also, the lever F may be operated to drive the machine by one person while another manages the work.

To the halved outer end of the lever F, or to an arm or bar attached to the said end, is hinged the handpiece L, so that the said'handpiece L may be turned down out of the way when not required for use.

The inner end of the hand-piece L is notched to engage with a catch-bolt, M, which works in a recess ill the lever F, or in a sleeve or keeper attached to the said lever. The catchbolt M is held forward by a spiral spring, N, placed in the recess in the lever F, and connected with the said catch-bolt M, as shown in Fig. or in any other convenient way.

The rear end of the catch-bolt M is bent outward and projects to serve as a handle for drawing back the said catch-boltM and allowing the hand-piece L to drop down.

The forward end of the catch-bolt M is beveled, so that it may be pushed back by the inner end of the hand-piece L when the said hand-piece is raised.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a sewing-machine motor, the combination, with the treadle D, of the hand-lever F, the connecting-rod H, and the adjustable rod I, substantially as herein shown and described, whereby the sewing-machine can be driven by hand-power, or by hand and foot power combined, as set forth.

2. In a sewing-machine motor, the combina- 'tion, with the hand-lever F, of the jointed hand-piece L and the spring catch-bolt M N, substantially as herein shown and described, whereby the hand-piece, when not in use, can be turned down out of the way, as set forth.

JOSEPH V. MORTON.
