KNOCKER FOR TRAVELING CARRIERS.

SPECIFICATION forming part of Letters Patent No. 767,652, dated August 16, 1904.

Application filed Afigust 6, 1963.

To all whom it may concern.-

Be it known that 1, DAVID M. MOTHERWELL, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented a new and useful Improvement in Knockers for Traveling Carriers, of which the following is a specification.

My invention relates to stops or knockers for traveling carriers, and is especially adapted for use with carriers which operate to raise a load vertically, convey it horizontally along a horizontally-suspended ropev or cable, and release it at a desired point beneath the rope or cable.

The .object of my invention is to provide a stop or knocker which may be coupled over the rope or cable (without the necessity of taking down the latter) and locked thereon against longitudinal movement, while left free to swing from side to side thereon, thereby contacting properly with the releasing mechanism of the carrier in the different positions which-the carriers and stops are likely to assume when the rope is kinked or turned.

A further object is to provide a stop or knocker which may be readily removed from the cable or shifted from point to point thereon without taking down or otherwise disturbing the cable.

In the drawings, Figure 1 is a side view of astop embodying my invention adapted to operate the releasing mechanism of the traveling carrier shown. Fig. 2 is a top view of the frame of the carrier on line 2 of Fig. 1.

Fig. 3 is a central longitudinal section of the stop and carrier. Fig. 4 is a sectional view on line 4 of Fig. 3. Fig. 5 is a view on line 6 of Fig. 1 looking in the direction of the arrow. Fig. 6isasimilar view on line 7 ofFig. 1.

A indicates any suitable carrier adapted to operate with the stop E. ,It consists, preferably, of the two parts 8 and 9, fastened together by bolts or rivets 10, 11', 12, 13, 14, and 15, the bolts 14 and 15 being the axes about which the flanged wheels 16 and 17 turn. The bolts 12 and 13 support the flanged pulleys 18 and 19, while the bolts 10 and 11 support the detents 20 and 21. The frame and wheels may be of Serial No. 168.494. (N0 model.)

any suitable construction adapted to travel upon the track or cable and support the .pulleys and detents.

B indicates the track or cable, adapted to be stretched between points of support and to afford a rail-support and guide for wheels 16 and 17 It is usually constructed of steel or iron and is adapted to support considerable weight. Where the weightis less or where for other reasons it is desirable, the trolley may be run on ropes, rods, wires, or other suitable ways. The track may be suspended in any suitable manner, preferably by securing the ends to uprights. Figs. 1, 6, and 8 illustrate my preferred form of movable stop E, secured to the cable or track. This I construct in two the stop to be turned over or swung about freely and to be coupled around the rope or cable from the sides. 'At any point on the stop, preferably near the end, is cut out the eye or arched opening 36, and to the portion of the cable thus exposed are bolted the clamps 37 and 38 by means of bolts 39 and 40. Each clamp is curved or cut away about the rope B to afford a better grip around the rope. The insertion of these clampingmembers preventslongitudinal movement of the stop along the cable or rope. By removing these the stop may be shifted to other points along the cable or track and secured by again aflixing the clamp within the opening 36, or the two is also desirable to flare the ends of the guideway so that if the trolley should become twistedout of the vertical the head 42 will still be forced into the guideway and the trolley and stop brought into the same vertical plane. The stop or knocker and the carrier will operate upon ropes of different sizes. In the smallest sizes the semitubular stop- sections 30 and 31 are held by the cross-bolts 32, 33, 34, and 35 in close contact, while with the large size ropes a space may be left between them.

0 indicates the trip through which the hoisting-rope D is passed and which has the hook or coupling 22 depending from it for engaging and securing the load and the knob 23 pro jecting upward adapted to operate detents 20 and 21. While the drawings show two pulleys 18 and 19 on the frame A and the hoisting-rope D knotted to prevent its passing between the frame and the flanged pulley 18, thence passed beneath the flanged pulley 24 in the trip (1, and over the flanged pulley 19, the load being supported by the hook 22 on trip C, it is obvious that any combination of ropes and pulleys which will raise and lower the load and cause the knob on the trip to operate'the detents and any means for attaching the load to the trip may be used to advantage. Detents 20 and 21 are pivoted to turn about bolts 10 and 11, respectively. They are so placed that when their lower portions are brought together the parts 25 and 26 form jaws which engage or bolt the knob 23 and support the load secured to trip C. On the upper or heel portion of each detent are the notches or click-surfaces 27 and 28, each adapted to em brace the block 44 of the drop-bolt 29. This drop-bolt consists of a shank having the head 42 and the block 44 large enough when resting in notches 27 to hold the jaws 25 and 26 together. The bolt is also provided with vertical side guides 45, sliding in channels 46. Having thus described my device, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, the track, a knocker, a sleeve secured to the knocker and extending up over the track and forming a supplemental track-section and a clamp on the track, said knocker having a head loosely engaging the clamp, substantially as described.

2. In combination, a knocker, a clamp on the track comprising the two members secured together by bolts and a head on the knocker loosely engaging the clamp the said head being formed of open-work to permit access to the clamp, substantially as described.

3. In combination with a cable track a knocker comprising a plate extending below and laterally on each side of the track and means for securing the said knocker adapted to support the knocker on tracks of different sizes, substantially as described.

4. In combination a knocker comprising a plate extending below and laterally on each side of the track and suspending means therefor adapted to fit cable-tracks of different sizes, substantially as described.

5. A knocker for hay-carrier or like tracks comprising a parthaving a catch or lug and having means for suspending it from the track and means on the knocker having jaws reaching up alongside the track to engage a projection on the track to hold the knocker against movement longitudinally of the track, substantially as described.

6. Aknocker for hay-carrier or like tracks comprising a part having a catch or lug with a sleeve for suspending the said part from the track and means independent of the sleeve for engaging a projection on the track to hold the knocker against longitudinal displacement.

7. A knocker for hay-carriers or'the like comprising a sleeve forming a supplemental track-section and a part suspended thereby and having a catch thereon and means at one end only of the knocker to engage a projection on the track for holding the knocker against movement in both directions.
