MORRIS SAPO, OF NEW YORK, N. Y.

PIN-CLUTCH.

Application filed August 5, 1916.

To all whom it may concern:

Be it known that T, Monnis SAPO, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and improved Pinlutch, of which the following is a full, clear, and exact description.

My invention relates to a pin clutch. object thereof is to provide a simple, effective and inconspicuous clutch which can be fitted from either end and which will positively grip the pin so that the pin cannot be released accidentally.

\Vith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of a pin provided with an embodiment of my invention;

Fig. 2 is a vertical section on line 2-2, Fig. 4,;

Fig. 3 is a similar section showing the clutch in position releasing the pin; and

Fig. 4 is a transverse section on line 4i-, Fig. 2.

Referring to the drawings, 5 is a carrier, which is in the shape of a disk having an elliptical contour. It has a rectangular cutout 6 in the longitudinal axis thereof. The disk has also grooves 7 in the longitudinal axis thereof which are the bearings for a pin 8 to which the clutch is to be locked.

A longitudinally-grooved block 9 is mounted to slide in the cut-out 6, the groove fitting the pin 8 snugly. The block 9 has a transverse open notch 10 in one side thereof substantially midway between the ends of the block. This notch has substantially the depth of the groove in the block.

A tongue 11 has a circular head 12 which fits into a circular recess 13 in the carrier 5. The carrier has a triangular cut-out 14 one apex of which merges with the circular recess 13, and the base opposite the said apex merges with the cut-out 6. The triangular cut-out, as well as the recess 13, is disposed on the transverse axis of they disk which forms the carrier, and the slope of the sides of said triangular cut-out 14 are such that Specification of Letters Patent.

Serial No. 113,252.

the tongue 11 will not touch the sides when the block 9 is moved to abut against either end of the cut-out 6. The length of the tongue 11 is such that the end thereof enters the groove of the block 9. The said end is sharpened to jam the pin as the block is moved from either end of the cut-out (3 to the middle thereof.

The carrier 5 has alining recesses 15 entering the triangular cut-out 14 and disposed substantially at right angles to the transverse axis of the carrier. Each of said re cesses constitutes a pocket for a coil spring 16, one end of which abuts against the bot tom of the pocket and the other against the tongue 11. The tendency of the springs is to maintain the tongue in the short axis of the carrier and, therefore, move the block midway between the ends of the cut-out6. The block9 has a stud 17 which projects through a slot 18 formed in housing 19 which incloses the carrier and the various members thereon. The stud 17 is provided with a head 20 whereby the block may be moved within the cut-out 6.

The housing 9 has apertures in the peripheral wall registering with the groove 7 in the carrier through which the pin may be entered. In passing" the pin through either end of the clutch, the pin will come into engagement with the end of the tongue in the grooved block 6 and force the tongue, and therewith the block, to move to the position shown in Fig. 3, thereby allowing a free passage to the pin. When the casing of the clutch is released, the compressed spring 16 will move the tongue and therewith the block, bringing the sharp end of the tongue against the body of the pin and jamming the pin in the carrier. To release the clutch from the pin it. is necessary to displace the block 9 through the medium of the head 20, whereby the tongue is disengaged from the pin, which may then be withdrawn by simply pulling the clutch.

,imLclann:

1. A pin clutch comprising a carrier, a block slidably mounted in the carrier and having a passage for a pin, a tongue mounted to swing in the carrier and engaging the block, said tongue having a sharp end lying in the passage of block, a yielding member in the carrier engaging the tongue and normally tending to bring the said extremity of the tongue into the passage.

2. A pin clutch comprising a carrier in the shape of an elongated disk, said disk having a longitudinal rectangular cut-out, a grooved block mounted to slide in the cutout, means extending from the block for sliding the block, a tongue pivotally mounted in the carrier and engaging the block with the free end thereof, and oppositely disposed springs in the carrier engaging the tongue intended to bring the free end of said tongue into the groove of the block.

3. A pin. clutch comprising an ovalshaped disk provided with a rectangular cut-out in the longitudinal axis thereof, a grooved block mounted to slide in the cutout, said disk having slots alining with the grooved block, a tongue pivotally mounted in the carrier and engaging the block with the free end thereof, oppositely disposed springs in the carrier engaging the tongue for maintaining the free end of said tongue in the groove of the block, a housing inclosing the carrier, a slot in said housing, a stud projecting from the block through the slot in the housing, and a head on the pin outside the housing for facilitating the displacement of the block in the carrier.

a l. A pin clutch comprising a carrier in the shape of an oval disk provided with a cut-out in the longitudinal axis thereof, and a triangular cut-out in the transverse axis thereof to one side of the rectangular cut-out, one base of said triangular cut-out merging into the rectangular cut-out, a

tongue mounted to swing in the triangular cut-out of the carrier so that the free end thereof enters the rectangular cut-out, a slotted block slidably mounted in the rectangular cut-out and engaged by the free end of the tongue, said carrier having a1ining pockets entering the triangular cut-out and disposed parallelly to the longitudinal axis of the carrier, a spring in each pocket engaging the tongue whereby the tongue has a tendency to be disposed at right angles to the rectangular cut-out, said carrier having groo 'es in the longitudinal axis thereof alining with the grooved block, a casing for the carrier, said casing having a slot, and a stud projecting from the grooved block through the slot whereby said bloclc may be displaced, substantially as and for the purpose set forth.

A pin clutch comprising an apertured carrier for receiving a pin, a grooved block slidably mounted in the carrier, the groove of the hloclt aiining with the apertures of the block, a tongue mounted to swing in the carrier, said tongue having a sharp end adapted to enter the groove of the block, means engaging the tongue and normally tending to bring the sharp extremity of the tongue into the groove, and a stud for displacing the block in the carrier, substantially as and for the purpose set forth.
