PoGGfB. Wat Z76 Patented Apr. 1, 1947 TRAVELLER-APPLYING TOOL Roger B. Watts, Nashua, N. E, assignor to Vi/hitin Machine Works, Whitinsville, Mass, a corporation of Massachusetts Application October 14, 1944, Serial No. 558,766

2 Claims.

This invention relates to a tool for applying a traveller to a spinning or twisting ring, and relates more particularly to a tool for applying a relatively heavy traveller to a large ring of the vertical flange type. Such travellers are made of stiff and heavy wire and necessitate the application of substantial force to snap th traveller ove the vertical flange of the ring and into running position.

It is the general object of my invention to provide an improved hand tool for effecting the above defined operation.

A further object is to provide a tool having provision for storage of a supply of travellers and for semi-automatic feed of successive travellers to applying position, together with means to release the selected traveller and to force it over the vertical flange to operative or running position.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a side elevation of my improved tool, with a ring shown in section;

Fig. 2 is a sectional plan view thereof, taken along the'line 2-2 in Fig. 1;

Fig. 3 is a side elevation of a cam plate and lever to be described;

Fig. 4 is a plan view of a storage member;

Figs. 5, 6 and 7 are detail end elevations, looking in the direction of the arrow in Fig, 1 and showing successive positions of certain operative parts; and

Figs. 8, 9 and 10 are detail views showing successive steps in the application of a released traveller to a vertical flange ring.

In the drawings, I have shown a portion of a vertical-flange type twister ring R mounted in a. ring rail l5. My improved traveller-applying tool comprises a main bar or support 2 adapted to rest on the top of the ring R and having an offset end portion 2! engaging the inner face of the ring.

The travellers T may have the usual outline shown in Fig. 8 and are assembled on an upwardly extending storage bar which is secured to the top of the bar 2! in any convenient manner as by a screw 26.

A guard in the form of an inverted U- shaped member is mounted on th bar 2t, to the left of the storage bar 25 as viewed in Fig. 1. The guard supports a, cross-pin or stud 32 on which a feed lever as is pivoted. A spring 34 is centered on the stud 32 and acts to 'force the right-hand or operative. end of the lever 33 to the depressed or holding position shown in Figs. 5 or 7.

A cam plate 46 (Fig. 3) is mounted on a lever it, which lever is pivoted at 42 to a bracket 43 secured to the end portion 2! of the bar 20 and having a flange M projecting under the ring R. The cam plate Ml has a traveller-engaging end portion 45 and a cam-shaped pressure-applying portion 46.

A spring clip 5% may be provided to prevent displacement of the travellers in storage on the storage bar 25, and the

upper end portions

52 and 53 of the storage bar may be oppositely beveled to facilitate application of travellers thereto.

Having described the details of construction of my improved traveller-applying tool, the method of its operation and use is as follows:

The offset end portion 2! of the tool is inserted through the ring R and th flange 44 is hooked under the ring. The lever 4| is then pressed downward sufficiently to elevate the travellerretaining end 35 of the feed lever 33. The end 35 is thus moved to the position shown in Fig. 6 and the lowermost traveller T is released for movement to the advanced position also shown in Fig. 6, such movement being efiected by the weight of the travellers assembled on the storage bar 25,

The lever 4| is then swung upward, raising its cam plate all to the position shown in Fig 7. At the same time, the feed lever 33 is released and the spring 34 pushes the end 35 of the lever downward to th position shown in Fig. '7, permitting the lowermost traveller only to move under the cam plate ill (Fig, '7) and to then drop to the position shown in Fig. 8. At the same time, the end 35 of the lever 33 holds back the remaining travellers, as indicated in Figs. 5 and '7.

The lever 4| is then moved downward to engage its cam plate Ml with the released traveler T, as shown in Fig. 8, and substantial pressure is then applied to the lever M, as indicated in. Fig. 9. Such application of pressure causes the cam portion it of the cam plate to depress and distort the traveller sufliciently to snap the lower end of the traveller under the lower flange of the ring R to the running position shown in Fig. 10. During this application of downward pressure, the part of the cam plate prevents transverse displacement of the traveller.

The traveller T is shown in Fig. 9 at the point 3 where it is just about to snap under the lower edge of the vertical flange.

The traveller T is thus quickly and easily applied and placed in running position, after which the applying tool is removed and is available to apply another traveller to any other ring requiring traveller replacement.

The entire traveller-applying operation is carried out by first slightly depressing the lever 4|, then substantially raising the lever, and finally again depressing the lever and applying firm pressure thereto, all of which operations may be 7 quickly and easily performed manually by the operator.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. A tool for applying travellers to verticalflange type rings comprising a traveller storage, a feed lever, a spring to move said feed lever to traveller-retarding position, a hand lever effective to rock said feed lever and advance a single traveller, and a cam plate on said hand lever movable in one direction to release said advanced traveller and movable in a reverse direction to engage said released traveller and to transmit manual pressure from said hand lever to said traveller. to snap said traveller over the lower edge of said vertical flange.

2. A tool for applying travellers to vertical- 4 flange type rings comprising a traveller storage, a feed lever, a spring to move said feed lever to traveller-retarding position, a hand lever effective to rock said feed lever and advance a single traveller, and a cam plate on said hand lever movable in one direction to release said advanced traveller and movable in a reverse direction to engage said released traveller and to transmit manual pressure from said hand lever to said traveller to snap said traveller over the lower edge of said vertical flange, said cam plate when in lowered position preventing escape of the lowermost traveller from storage and said feed lever preventing advance of the next to the lowermost traveller when said lowermost traveller is released.
