Description

No. 808,046. PATENTED DE 19 H. W. HADLEY. C O5 SEWING MACHINE.
APPLICATION FILED MAY 17,1905.
UNITED STATES PATENT OFFICE.
HORACE W. HADLEY. OF BELVIDERE, ILLINOIS, ASSIGNOR TO AMERICA COMPANY, OF ROCKFORD, ILLINOIS, A CORPORATION OF ILLINOIS.
SEWING-MACHINE.
Specification of Letters Patent.
Patented Dec. 19, 1905.
To all whom it may concern:
Be it known that I, HORACE WV. HADLEY, a citizen of the United States, residing at Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification.
The object of this invention is to impart the proper movements to the needle-bar and hook-shaft from a rotatable cam.
The further object of this invention is to impart to the needle-bar and hook-shaft a series of complete movements to each revolution of the cam.
In the accompanying drawings, Figure 1 is an elevation of a sewing-machine containing my improvements. Fig. 2 is a face elevation of the cam and the bar connecting the needlebar and hook-shaft.
The sewing-machine comprises the base 1,
overhanging arm' 2, supporting the guide 3 for the needle-bar 4. A shaft 5 is supported by the base 1, to one end of which is secured the hook 6 and to its other end is secured a crank-arm 7. The table or shelf 8 supports the work, the presser-foot 9, and the gagebar 10.
To the side of the overhanging arm 2 is pivoted needle-arm 11 intermediate its ends. One end of this needle-arm has a pivotal connection with the needle-bar 4. The end 12 of this needle-arm has a hole 13. From the overhanging arm 2 extends a lug 14, which supports a stud 15. A driving-wheel 16 is mounted on the stub-shaft 15 in a manner to ermit of its rotation. This wheel has a puley 18, over which a belt may be placed, and also has a handle 19, by which it may be turned. The inner face of this driving-wheel has a cam groove 17 formed therein, said groove being elliptical in shape for a purpose presently to appear.
A pitman 20 has one end ivotally connected to the crank-arm 7 on t e shaft 5, and its other end su ports a pin 21, which is located in the ho e 13 in the needle-arm 11. This pitman 20 has a lengthwise-extending slot 22, which receives the stub-shaft 15, supporting the driving-wheel 16. A frictionroller 23 is supported by the pitman 20 and is located in the cam-groove 17. As the driving-wheel is rotated the cam will rotate with it. This movement of the cam will impart a lengthwise movement to the pitman 20 and through its connection with the crank-arm 7 will oscillate the shaft 5 and the hook 6 connected with it. This movement of the pitman 20 will rock the needle-arm 1 1 on its pivotal connection with the overhanging arm 2, which will reciprocate the needle-bar and the needle carried by it. The cam will, by reason of its peculiar shape, as described, impart a series of complete reciprocations to the pitman 20 during each revolution thereof, and these reciprocations will cause a corresponding number of complete movements to be imparted to both the needle-arm 11 and the hookshaft 5. In other words, the needlebar 4 and hook 6 will be given two complete movements to each single revolution of the wheel and cam. I,
I claim as my invention- I In a hand-operated sewing-machine, the combination with the pivoted needle-arm, the needle-bar, and the oscillatory hookshaft, of a wheel arranged at right angles to said arm and having an elliptical cam-groove in its inner face and a hand-crank, a stubshaft on which saidwheel is j ournaled, a pitman having a connection at one end with the needle-arm, and at its other end with a crank on the hook-shaft, and a friction-roller journaled on one side of the pitman and traveling in the said cam-groove, the construction and arrangement of the parts bein such that a single revolution of said wheel will impart two complete up-and-down movements to the needle-bar and two complete oscillations to the hook-shaft.
HORACE W. HADLEY.
