7 Claims.

This invention relates to an article manipulating apparatus and more particularly to a fixture for holding a terminal plug in which the terminal plug may befirmly held in any one of a number of positions.

In fastening a plurality of conductors forming parts of a multi-conductor cable to terminals carried by a component of a cable plug, it is necessary to hold the component firmly while attaching one of the conductors to a terminal and then turn it to and firmly hold it in another position while attaching a second conductor to a second terminal. If a stationary vise is used to hold the insert, it must be loosened to rotate the component to the second position and tightened again, which is time-consuming. If the component is held manually, the tool employed by the operator might slip and injure his hand.

It is an object of this invention to provide a new and improved article manipulating apparatus.

An apparatus for holding cable plugs embodying the present invention comprises a frame carrying a rotatable ring provided with a plurality of circumferential openings, a detent which engages the openings to selectively position the ring, and a releasable clamp mounted on the ring for securing a cable plug within the rotatable ring.

This invention may be completely understood from the following detailed description and the accompanying drawing, in which Fig. 1 is a perspective view of an article manipulating device embodying the invention, and

Fig. 2 is a sectional view thereof taken along the line 22 in Fig. 1.

In the particular embodiment of the invention disclosed in the accompanying drawing, there is provided an L-shaped frame I!) (Fig. 1), which may be secured to a work table. The frame ID has a semicircular cut out portion ll therein (Fig. 2). A companion frame member l2, which is adapted to be secured to the L-shaped frame ID by bolts 5-15, has a semicircular cut out portion l6 of the same radius as and complementary to the semicircular portion l I, so that these cut out portions form a circular opening when the frame member I2 is joined to the frame ID.

A bushing l9, having a circumferential groove 20 therein which conforms to cut out portions II and I6 in the frames l0 and I2, is rotatably secured in the opening formed by the cut out portions of the frames l0 and I2 which fit into the groove 20. The bushing l9 has a plurality of spaced radial apertures 2l-2l therein. The

top of a pin 22 is engaged by a leaf spring 25 which tends to urge the pin downwardly through an aperture 24 in the frame l2 into one of the apertures 2|-2| to secure the bushing l9 against rotation. The pin 22 is provided with a socket 23 into which is inserted a reduced portion 3| of a lever which is pivoted on a pin 21 mounted in ears 26-26 of the frame l2.

A semicircular shoulder of the flanged bushing 28 has a semicircular article gripping surface 36 thereon and a slot 38 formed therein in which alatch 40 is pivotally secured by a pin 4!. A collar 42 is adjustably secured on the pivoted latch 40 by set screws 43-43 and has a cam surface 44 formed thereon. An arcuate lamp 45 is pivotally mounted on a pin 46 projecting therethrough and through a lug 41 formed on the semicircular shoulder 35. The clamp 45 has a semicircular article gripping surface 50 and is provided with a pair of rounded tongues 5i-5|, forming a slot 52 therebetween through which the latch 40 enters, and on which the cam surface 44 slides to draw the clamp 45 against the shoulder 35.

In the operation of the above-described fixture, a cable plug 53, to which conductors are to be secured, is inserted between the

article gripping surfaces

36 and 50. The clamp 45 is drawn down and secured by swinging the latch 40 into the slot 52 and forcing the cam surface 44 of the collar 42 over the arcuate tongues 5l5l. The lever 30 is pressed downwardly to raise the pin 22 from the particular aperture 2| in which it has been inserted. and the bushing l9 and the plug 53 held therein may then be rotated to any suitable.

ing I9 holding it may be rotated to another position, as previously described, without unclamping the plug. Very little time will be consumed in changing to a position in which one of the other of the conductors may be more conveniently attached to another terminal 54. The operation is repeated until all of the conductors are attached to the terminals 54-54. The latch 40 is then removed from the slot 52 to release the clamp 45 and the plug is removed from the fixture. Another plug may then be clamped in the fixture and the operations repeated.

If it is desired to substitute another bushing having the shoulder 35 and clamp 45 thereon 5 the substitute bushing is rotatably secured between the frames and I2 similarly to the original bushing.

Many variations from the particular embodiment of the invention disclosed in the accompanying drawing may be made without departing from the scope of the invention, which is limited only by the claims.

What is claimed is:

1. An article manipulating apparatus comprising a frame consisting of an L-shaped base having a semicircular cut out portion therein, a frame member removably secured to the base and having a semicircular cut out portion therein which coacts with the semicircular out out portion in the base to form a circular opening, a double flanged bushing rotatably secured in the circular opening and having a plurality of radial holes spaced about the periphery thereof, a semicircular shoulder formed on the bushing, a semicircular clamp pivoted on the shoulder and having a slot in the end thereof, a latch pivotally connected to the shoulder and designed to enter the slot in the clamp and having a cam thereon for engaging the clamp .above the slot to secure an article between the shoulder and the clamp, a detent, a spring for urging the detent into one of the radial holes in the bushing to prevent rotation of the bushing, and means for withdrawing the detent from engagement with the radial hole to permit the bushing to hemtated.

2. An article manipulating apparatuscomprising a frame having a circular opening therein, a bushing rotatably mounted in the opening and having a plurality of radial apertures formed in the periphery thereof, a detent secured to the frame for entering any of the apertures to electively secure the bushing against rotation, and an article clamping means secured to the bushing adjacent to the circular opening, said article clamping means having work engaging surfaces extending around the axis of the bushing for securing an article extending into the bushing.

3. An article manipulating apparatus comprising a bushing having a plurality of radial apertures formed therein, a detent, a frame having a circular opening formed therein in which the bushing is rotatably mounted and also bein provided with a bore extending from the opening to th outer periphery thereof through which the detent extends for entering any of the radial apertures, wherebythe bushing may be secured an unobstructed passage against rotation in any of a plurality of positions, an arcuate projection extending from the bushing, and an arcuate member pivotally secured to the projection for cooperating therewith to secure an article therebetween, said arcuate projection and member forming a. work clamping surface of the general contour of the bushing opening and in alignment therewith.

. 4. An article manipulating apparatus, which comprises a frame, a cylindrical bushing rotatably secured to the frame for rotation about the axis thereof, said bushing having an article gripping surface thereon, a latch pivotally mounted on the bushing and having an article gripping surface thereon for cooperation with the firstmentioned gripping surface to secure an article, said gripping surfaces being located around and in alignment with the axis of the bushing, whereby the opening of the bushing will afford clearance for a secured article, and means to releasably secure the bushing against rotation.

5.
