Description
THOMAS J.HALL1'eAN,o-F NEW YORK, NL Y. Letters .Patent No. 70,835, dated November 12, 1 867; antedatecl November 1, 1867.
IMPRDVEMENT IN TREADLE FOB. SEWING MACHINES.
lTO ALL WHOM IT MAY CONCERN:
Be it known that I, THOMAS J. HALLIGAN, of the city, county, and State of New York, have invented a certain new and useful Im rovement on TreadleMotions for O cratinfr'Sewin Machines, and other ur cees,.-
P P s g P P of which the following is a full,lclear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a plan of a double-trcadle action or arrangement constructed according to my improvement. I
Figure 2, aside view of the same, and
Figure 3 a transverse section through the line a: :z: in fig. 1.
Like letters indicate corresponding parts throughout the several iigures.
My invention relates to what are vknown as double-treadle motions, in which two treadles,pworked by the right and left foot of the operator, are used for giving motion through separate connections to a common shaft; and the nature of myinvention consists in a peculiar construction and arrangement of the treadle-shafts, whereby the one is not only protected by but forms bearings for the support of the other; and in a combination of the same with suitable connections, and a double-throw crank for giving rotary motion to a common shaft.
Referring to the accompanying drawing, A B represent right and left-foot treadles, with rocking-foot pads ab attached. The one, A, of these treadles is connected with an outer hollow shaft, C, which not only serves as a cover to protect from injury an inner shaft, DJ to which the other treadle B is connected, but, .by a cylindrical formation of it at or near its ends, is supported by or has its bearings on said inner shaft. Intermediately of such bearings, the outer shaft-A may be only partially closed, or of V form, as represented in fig. 3, or itmay.
b'e of a closed form throughout its whole length. This construction and arrangement ofthe two treadle-shafts not merely cause the outer shaft to protect the inner one, and the latter to support the former, only rendering necessary two pedestals or outer bearings c c to the one shaft, but, by such arrangement, the same or nearly the same compactness is secured as a singlc-treadle action possesses. To add to this compactness, as far as consistent with a double-treadle motion, and to enhance the efficiency of such an arrangement, the two shafts C D have their driving-levers E F connected, by pitmen G H, with opposite ends of a double-throw crank, I, .carried by a iiywvheel. J, or other device made fast to or connected with a shaft, K, to which the treadles give a rotary motion, and which may represent the main or driving-shaft of a sewing machine; the standard L that forms Aone of the supports to said shaft representing the one-end portion of the frame of such a machine.
For sewing heavy work, this double-treadle arrangement will-be found very advantageous in sewing machines generally; the ease and regularity with which both treadles may be worked, economizing-time and labor, while, bythe special construction and arrangement of the parts herein described, great compactness and simplicity are secured. i
What I claim as my invention, and desire to secure by Letters Patent, is
1. The construction and arrangement, substantially as herein described, of the treadle-shafts C D with their'treadles A B for operation in unison, and whereby said shafts are made, the one to support and protect the other, essentially as herein set forth.
2. Thelcombination of the treadle-shafts C D, arranged as described, with their treadles A B, driving-arms or levers E F, pitmen G H, und double-throw crank I, of or to the revolving-shaft K, substantially as vshown and described.
