MECHANISM FOR PROVIOING ROTATION AND RECIPROCATION FROM A SINGLE DRIVING-GEAR.

SPECIFICATION forming part of Letters Patent No. 762,719, dated June 14, 1904:.

Application filed July 17, 1903. Serial No. 165,973. (No model.)

To all whom ztmay concern;

Be it known that I, HARRYA. HOUSEMAN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Mechanism for Providing Rotation and Reciprocation from a Single Driving-Gear, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

I will first describe the embodiment of my invention as illustrated in the accompanying drawings and then point out the invention in I 5 the claims.

In the drawings, Figure 1 is a front elevation of a circular-knitting machine embodying my invention. Fig. 2 is a rear elevation of same with the top structure broken away.

Fig. 3 is a sectional plan. Fig. 4 is a sectional elevation on line 4 4, Fig. 3. i

X is the bed-plate of the machine.

A is the main driving-gear of the machine. This gear is supported on the vertical stud m,

supported by the bed-plate X. As shown in the drawings, this gear A is driven in the following manner: Connected with or formed upon one face of the gearA is the bevel-gear B, meshing with the bevel-gear B upon the shaft O. Upon this shaft is the fixed pulley D and the idle pulley D and the cranl; D D is the driving-belt. The gear A is supported upon the stud a. The gear A meshes with the gear E, loose upon the shaft E. 3 5 This shaft E projects vertically above and below from the bed-plate X, having its upper bearing on the bed-plate X. Fixed upon this shaft E is the gear E and the gear E the gear E meshing with the gear Fupon 4 the cam-cylinder F.

G is the needle-cylinder. Gr is a clutch feathered upon the shaft E. H is a crank-rod secured to one face of the gear A and connected to a crank H, connected to one end of the sleeve H upon the stud H", the segmental gear H* being connected to the other end of said sleeve. projects vertically from the bed-plate X and to a common clutch-rod H".

The stud H is supported at one end by said bed-plate. This segmental gear meshes with the gear H, 5 loose upon the stud H. The stud H projects vertically from and is supported by the bedplate X. Loose upon this stud H" is the gear H which meshes with the gear E The clutch G is provided with the lug g, which when the clutch is shifted into engagement with gear E alines with projection g upon the gear E, and thus the gear E is "brought into engagement with shaft E, and

.clutch G and clutch-pins 72, h for engagement and disengagement with their respective gears are with respect to each other in opposite directions, so that the gear E" cannot at any time be in engagement both with the rotary gear E and the reciprocating gearH G is a clutch-lever connected to clutch G, and H is a clutch-lever connected to the gear These two clutch-levers are connected The mechanism for operating this clutch-rod so as to shift the clutches to bring the gear E under the influence-of the rotary and reciprocatory motion at the proper times which I use is that shown and described in Letters Patent issued 8 5 to me April 30, 1895, No. 538,518, and therefore need not here be described in detail.

This mechanism for providing rotation and reciprocation from a single driving-gear I have shown and described as applied to drive 9 the cam-cylinder of a knitting-machine; but it is clear'that it can be applied to drive other mechanism, and unless specifically claimed in connection with a knitting-machine I do not intend it to be so limited.
