NTE STATES PATENT OFFICE,
IIOlVARD E. IIARBAUGH, OF KENOSHA, \VISCONSIN, ASSIGNOR TO THE CHICAGO-ROCKFORD l-IOSIERY COMPANY, OF SAME PLACE.
lVl ECHAN ICAL IVIOVEM ENT.
SPECIFICATION forming part of Letters Patent No. 552,527, dated January 7, 1896.
Application filed September 15, 1894. Serial No. 523,165. (No model.)
of Wisconsin, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.
My invention relates to mechanism for automatically regulating the speed of ratchetwheels; and it consists of certain new and useful features of construction and combinations of parts specifically devised to that end, all of which are hereinafter fully described, and particularly pointed out in the claims.
Referring to the accompanying drawings, which form a part of this specification, Figure 1 is an isometric view of mechanism embodying my improvement. Fig. 2 is a detailed view of parts of the same.
Like letters of reference indicate correspondin g parts in both views.
Ais the bed-piece of the machine, provided with an upwardly-projecting annular flange A, preferably integral therewith.
B is a ratchet-wheel mounted on the bedpiece A, concentrically with the annular flange A, provided, with a device B, the
function whereof will be hereinafter fully described.
O is a standard for supporting parts of the machine, and is fast to the bed-piece A.
E is a rock-shaft mounted in the bed-piece A and bearing E on the standard 0.
1 is a walking-beam, mounted on the rockshaft E, provided with a pallet G, pivotjointed thereto at F. The point of the pallet G is rendered longitudinally adjustable by means of the socket G and set-screw G 11 is a stud rigidly connected with the part F by means of a socket H and a set-screw H The stud l-I obviously might be integral with the part F, but for the convenience of adjusting the same, with reference to the part B, the construction shown is preferable.
I is a rotatable shaft, having a wheel 1 fast thereto provided with a cam I projecting from the inner face thereof,
J is an arm fast by one end to the rock-shaft E and provided at its other end with. a roller J mounted on a bearing J 2 thereon,
K is a spring normally maintaining the pallet G into engagement with the ratchetwheel B and the roller J into engagement with the inner face of the pulley I.
The operation of my machine is as follows: Rotate the wheel I, and the cam 1 impinging against the periphery of the roller J, will, through the media of the arm J and rockshaft E, oscillate the-walking-beam F, which will drive the pawl G, thereby rotating the ratchet-wheel B. WVhile the part H is opposite the device B, as shown in the drawings,
' the pallet G will only pass one tooth of the ratchet-wheel B at each impulse thereof; but after the device B has traveled out of reach of the part H the oscillations of the walkingbeam F will increase in length until the pallet G will pass two teeth of the ratchet-wheel at each impulse. Obviously the device B may be of any desired width or length within the limits of the mechanism, its width determining the number of teeth that the pallet G will pass at each impulse thereof, and its length determining what part of each revolution of the ratchet-wheel shall be made at its minimum rate of speed, from which it will be seen that the mechanism may be caused to automatically increase or diminish the speed of the ratchet-wheel B at predetermined intervals by employment of the device B, which may be multiplied in number or increased or decreased in width or length, as already stated.
The cam I on the wheel I is shown of sufficient width to permit an extreme stroke length by the pallet G of two teeth of the ratchet-wheel B. Obviously if the cam I were diminished one-half in width the stroke length of the pallet Gr would be diminished one-half, and if it were doubled in width the stroke length of the pallet would be doubled in length. By width of the cam I the distance taken transversely through its center parallel to the axis of the wheel I is meant.
The herein-described mechanism, as illustrated in the drawings, is employed as a pattern-wheel for knitting-machines. lit obviously might, however, be adapted for use wherever it is requisite to automatically regulate the speed of a ratchet-wheelthat is, cause it to perform a part or parts of a revolution either more or less rapidly than the remainder thereof.
I claim 1. In a mechanical movement, in combination, a pallet for driving a ratchet-Wheel, a ratchet- Wheel, a device carried by said ratchet-Wheel for regulating the stroke-length of said pallet and a part acted upon by said device and connected to the pallet, substantially as and for the purpose specified.
2. I11 a mechanical movement, in combination, a walking-beam provided at one end With a pallet, a rotatably-mounted ratchetwheel adapted to be engaged and driven by said pallet, a device carried by said ratchetwheel-acting through the free end of the Walking-beamf0r regulating the length of the stroke of the pallet, and means for oscillating said walking-beam, substantially as and for the purpose specified.
