3 Claims.

This invention relates to power transmitting mechanism for operating a glove turner, the said glove turner being of conventional form, in which one member is stationary and the other member reciprocates with relation to it, In general prac- 5 tice, the glove turner and its mechanism is actuated by a pedal or lever and its laborious -operation consumes considerable time,. as compared with the power actuating instrumentality of this invention.

It is an object of the invention to provide a driven member and a device for actuating a glove turner, which mechanism is intermittently actu ated by the power drive; means being provided for intermittently connecting the parts and' for l5 automatically disengaging the parts as the glove turner is being manipulated for a renewal of the operation.

It is furthermore an object to provide mechanism of this character which is comparatively 20 inexpensive, as well as efficient and satisfactory in use.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and' combination 25 of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like charac- 130 ters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a view in elevation showing a conventional type of glove turner and an end in elevation of the power transmitting mecha- 35 nism;

Figure 2 illustrates a plan view of a power drive for operating the glove turner;

Figure 3 illustrates a view in side elevation of the said driving mechanism;

Figure 4 illustrates a sectional view on the line 4 4 of Fig. 3; and

Figure 5 illustrates a sectional view of the clutch and drive.

In these drawings II denotes a suitably driven 45 jack shaft which may have power applied to it in any appropriate manner, but there is illustrated a pulley A which may be connected to the source of power. The jack shaft has another pulley I3 rotatable with it and it is to be belted 50 or otherwise connected to the pulley I5, which latter is secured on a shaft I6, it being shown that the pulley I5 has a sleeve IBa on the said shaft I6. The pulley I5 is in the nature of a disk and it has a clutch surface I 'I to be engaged by 55 mechanism for actuating the glove turner. The jack shaft, its mounting, and other parts arey of the more or less conventionaltype and need not, it is thought, be described in detail.

The means for actuating the glove turner, generally identified by the legend GT, comprises a rod I3 connected to an oscillating part I9 of the glove turner. The rod I8, in turn, has its lower end connected to an arm 2Q carried by a clutch member 2l which is preferably integral with a hub 22' loosely mounted on the shaft I6. The hub is actuated longitudinally of the shaft I6 through the employment of a collar 23 and operative t'o force the clutch member 2l longitudinally of the shaft to cause the lining 2 Ia, of the clutch member 2l to engage the clutch face Il, and when the members are clutched, the member 2| is partially rotated counter-clockwise from the position in which it is shown in Fig. 2, resulting in pulling the rod I 8 downwardly and operating the glove turner.

There is an arm 2?. mounted on a shaft 29, a part of the mechanism, having a hooked end 23a, as shown in Figure 3, and this engages a block 24 and arrests the rotary movement of the clutch member, and at this step of the operation, the clutch member is released and the glove turner, under the iniluence of the inherent spring 25, causes the clutch member to resume its initial position for a repetition of the operation. It is shown that a pedal or lever 26 is connected to a spring 21 and that the spring 2l is connected to the end of an arm 28, which is mounted on the shaft 29 and, of course, the shaft 29 is partially rotatable in suitable bearings. A two-armed yoke 30 is carried by a block 3| on the shaft 29 and the arms of the yoke each has a recess 30a in its outer end, in which lugs on the collar 23 are seated, so that as the yoke oscillates, it moves the clutch inwardly or retracts it, according t0 the direction of movement.

When the glove turner has been operated to a degree that the glove turning instrumentalities have coacted to turn the glove, which would occur when the rod I8 had drawn the lever I9 downwardly in the direction of the arrow, Figure 1, and the clutch had been released to interrupt further downward movement of the said lever, that part of the glove turner to which the lever i9 is pivoted would be subjected to the influence of the spring 25 which would have been extended during the said downward movement, and that part of the glove turner would be retracted under the inuence of the spring in the direction of the upwardly pointed arrow in Figure 1, and

to cushion the movement of the spring and arrest that part of the glove turner under the inuence of the spring, the machine of the invention would effect said cushioning. To accomplish that result, the clutch member 2| is provided with an arm Sla which encounters a brake band 32 eccentrically positioned with relation to the shaft I6. The brake band'has one end 33 anchored to an arm 34 extending from a standard or post 35 supported on a portion of the frame of the machine. The lower end of the brake band 32 has a lug 36, to which an end of a screw 31 is pivoted, and the said screw operates through a threaded bracket 38 on the base of the machine, and by manipulation of the screw the brake band may be adjusted t increase or diminish the frictional contact between the arm and the brake band, for the purpose of arresting the movement of the clutch member carrying the arm 20 which is connected through therod I9 to the glove turning mechanism.

I claim:

1. In a power drive for glove turners, a driven wheel having a clutch face, a shaft on which the Vwheel is secured, a clutch member slidable on the said shaft, means for moving the clutch member into engagement with the clutch face, including means for retracting it, an arm on the clutch member movable therewith, aconnection from said arm to a glove turning instrumentality, a lug on said clutch member, a second arm having its end in the path of travel of the said lug and operative for engagement therewith to arrest the movement of the clutch member in one direction, a third arm carried by the clutch member, and a brake band suitablysupported and positioned to engage the third arm at a predetermined zone .of travel of the said arm in an opposite direction of the clutch member.

2. In combination with a glove turner having a spring for retracting the glove turner after one step of an operation, means for operating the glove turner against the action of the spring, including a rod connected to said glove'turner, means for moving the rod longitudinally, including a suitably rotatable clutch element having a clutch face, a shaft on which the said clutch element is splined,Y a coacting clutch element turnable with said shaft, means for moving the first mentioned clutch element into and out of engagement With the second mentioned clutch element, an armv on the first mentioned clutch element to which the rod is connected, a lug on the rst mentioned clutch element, a second arm having an end in the path of travel of the lug for engaging the lug and arresting the first mentioned vclutch element, a third arm carried by the iirst mentioned clutch element, and a brake band in the path of travel of the third arm for braking the movement of the clutch element under the iniiuence of the spring of the glove turner.

3. In combination with a glove turner having a spring for retracting the glove turner after one step of an operation, means for operating the glove turner against the action of the spring, including a rod connected to said glove turner, means for moving the rod longitudinally, including a suitably rotatable clutch element having a clutch face, a shaft on which the said clutch element is splined, a coacting clutch element turnable with said shaft, means for moving the first mentioned clutch element into and out of engagement with the second mentioned clutch element, said means comprising a collar connected to the rst clutch element, a yoke having sliding connection with said collar, a shaft on which the yoke is mounted, a lever on the shaft for partially turning said shaft, a pedal and a yieldable connection between the pedal and the said lever for absorbing shock of operation, an arm on the first mentioned clutch element to which the rod is connected, a lug on the first mentionedclutch element, a second arm having an end in the path of travel of the lug for engaging the lug and arresting the rst mentioned clutch element, a third arm carried by the first mentioned clutch element, and -a brake band in the path of travel of the third arm for braking the movement of the clutch element under the influence of the spring of the glove turner.
