SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,961, dated November 10, 1896.

Original application filed June 24, 1892, Serial No. 437,876. Divided and this application filed February 20, 1893. Renewed August 6,1896. Serial No. 601,925. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM D. RUNDLETT, of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Sewing- Machines; and I do hereby declare the following specification, taken in connection with the accompanying drawing, forming a part of the same, to be a full, clear, and exact description thereof.

The present application is a division of pending application, Serial No. 437,876, filed June 24, 1892.

The invention hereinafter described relates to that class of sewing-machines in which an 'awl is employed to puncture a hole in the stock for the entrance of the needle, and in which the work is fed by means of such awl, and the invention is especially adapted for use in that class of machines in which a curved needle and a curved awl are arranged to be oscillated about a common center.

The object of the invention is to provide proper supports for the needle-head and the awlhead,respective1y, whereby they will both be prevented from tilting or cramping, and

' whereby they will always be held in accurate therein.

alinement with each other. To that end the invention consists in the combinations of parts hereinafter described.

Referring to. the drawings the figure is a view, partly in section, illustrating the invention.

B is a portion of the fixed frame of a sewing-machine.

6 is the needle-carrier, carrying the needle 7.

13 is the awl-carrier, carrying the awl 14.

The needle-carrier 6 and the awl-carrier 13 are each provided with elongated hubs and are both loosely mounted on a common shaft 15, as shown in the drawing, and so that both the needle and awl will move about a common center, but from opposite sides of the work. The shaft 15 is free to oscillate, as hereinafter more fully described. The hub of the needle-carrier 6 is loosely mounted in the frame B, so as to 'be capable of turning The hub of the awl-carrier 13 is loosely mounted in the arm 16, projecting from the feed-slide 118, arranged to be moved in its supporting-bracket 119 by suitable mechanism. The hub of the 'awl-carrier is' held in position in said arm- 16 by the check.- nut 17, the arrangement being such that the awl-carrier can oscillate in its supporting-arm 16 and about the shaft 15, and also be capable of a longitudinal movement upon said shaft 15 for the purpose of feeding the Work. The needle-guide 18 is rigidly secured to the shaft 15, which said shaft is free to oscillate, but has no end wise movement. Said needleguide is operated in one direction by a projection from the needle-carrier in a wellknown manner, and is operated in the other direction by the spring 19 acting upon the crank 20, which is rigidlysecured to the shaft 15, the opposite end of the spring 19 being secured to the frame of the machine.

As shown in the drawing, the hub of the needle-carrier is held between the hubs of the needle-guide 18 and the crank 20, which are rigidly secured to the shaft, 15, and is thus held against longitudinal movement upon said shaft, the needle-carrier, however, being free'to oscillate about said shaft.

It will be understood that the needle-carrier and the awl-carrier are each to be oscillated, and the awl-carrier moved to feed the Work by proper mechanism in the usual manner.

By the construction and arrangement of parts above described both the needle-can rier and the awl-carrier are supported both exteriorly and interiorly, and being each provided with elongated hubs are entirely prevented from cramping or tilting, notwithstanding that they are both loose and free to oscillate upon their supporting-shaft. Moreover, said needle-carrier and awl-carrier, being mounted upon a shaft common to both, are always maintained in accurate alinement with each other.

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

1. The combination of a shaft, a needlecarrier loosely mounted on said shaft and capable of being oscillated thereon, but having no lengthwise movement in relation thereto, an awl-carrier likewise loosely mounted on said shaft and capable of oscillating thereon and also of beingmoved lengthwise with relation to said shaft, both said needle and awl carriers beingprovided with elongated hubs surrounding said shaft, and an exteriorsupport for each of said hubs, the support for the needle-carrier hub being fixed and immovable, and the support for the awl-carrier hub being capable of lengthwise movement to move said awl-carrier and the awl held therein to feed the Work, substantially as described.

2. The combination of a shaft free to oscillate, but incapable of lengthwise movement, a needle-guide secured to said shaft, aneedlecarrier loosely mounted onsaid shaft 'andc'apable of being oscillated'thereon, but having no lengthwise movement in relation thereto, an awl-carrier likewise loosely mounted on scribed.
