TRAVELING CRANE OR CONVEYER.

SPECIFIOATION'fQrmingpart of Letters Patent No. 626,276, dated June 6, 1899.

Application filed JanuarylQ, 1399. Serial No. 702,685. (No model.)

To (ZZZ 1072,0121 it may concern.-

Be it known that I, ALEXANDER R. GOLDIE, a subject of the Queen of Great Britain, re-

siding at Galt, in the county of Waterloo,

Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Traveling Cranes or Conveyers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in traveling cranes or conveyers of the overhead type; and the object of the invention is to provide a simple, convenient, and positivelyoperating apparatus for preventing the sagging of the hose-pipe through which pressure is conveyed from a fixed point to the traveling carriage or, if the conveyer be not a hydraulically-operated conveyer,forsupporting the operating-cable or electrical conductors, as the case may be, so as to prevent any undue sagging of the same.

The further object of the invention is to so support the hose-pipe or cable as to cause a looping of the same at the end of the track or way instead of in proximity to the traveling carriage. Thus only that portion-of the pipe or cable is moved which is necessary to extend from the end of the track or way to the carriage.

In the accompanying drawings, Figure 1 is an elevation, of a diagrammatic character, showing my present apparatus in connection with a hose-pipe through which pressure is conveyed from a fixed point to a traveling carriage or crane. 'Fig. 2 is a similar View, on an enlarged scale, showing the hose-pipe or cable supporters and their controlling and operating devices. Figs. 3 and a are sectional views at right angles to Fig. 2, showing the mechanism for releasing the hose-pipe supporters from the operating-cable.

Like letters of reference in the several figures indicate the same parts.

Referring to Fig. 1, the letter A indicates a carriage supported to travel back and forth on any suitable track, cables, or ways-such as M, Fig. 1-of any ordinary or preferred type, and said carriage is adapted tobe moved back and forth by any ordinary or preferred mechanism, which is not shown in order to prevent obscurity or confusion in illustration of the present invention.

B indicates a track or way for the hose-pipe or cable supporters and is shown on an enlarged scale in Figs. 2, 3, and 4, being preferably a double -T girder supported in any suitable manner and extending parallel with the direction of movement of the carriage and from end to end of the shop or from end to end of the carriage-ways. At each end of this track B there is arranged a sheave O, and around these sheaves a wire or cable D passes, the opposite ends of this wire or cable being attached to the carriage, as at d, the wire or cable being thus caused to move in unison with the carriage in each direction.

Running on the track B, and preferably carried by rollers f, are a series ofv cable or hose-pipe supporters F, a sufficient number being employed to support the hose-pipe or cable at relatively short intervals to prevent any undue sagging of the same between the sides or ends of the track and the carriage. In the preferred arrangement the hose-pipe is clamped to the bottom or lower ends of these supporters by clamps f at the desired intervals, and the hose-pipe itself may be employed as a means whereby they are successively drawn away from the end of the track as the carriage travels away; but in the preferred construction and in order to relieve the hose-pipe or cable from strain the supporters are connected by light chains G, which will draw them successively along at the proper intervals to support the hose-pipe or cable. In order now to return the supporters to the end of the track as the carriage moves toward the end and in the reverse order to that in which they were drawn away, I provide the as indicated in the diagrammatic view, Fig.

1. As a convenient and practical means for connecting the cable or wire and its support ers tosecure this return movement the cable or wire D preferably passes th rough'apertures F in each of the supporters, such apertures being of a size sufficient to permit the buttons or enlargements D to pass therethrough as the cable or wire moves inone direction. On each of the supporters there is arrangeda catch or shutter H, having a slot which will permit the wire or cable D to pass therethrough, but which will not permit passage of the buttons orenlargements D. These shutters lI slide vertically in slots or openings extending down through the supporters F, and when in initial position these catches or shutters H are held up or out of operative relation to the wire or cable by means of a catch or shutter supporting track or incline K, thus permitting the cable and button to pass forward through the supporters; but when said supporters are drawn off or away from the incline K the shutters or catches will drop and prevent the passage in the reverse direction of the buttons or enlargements until the shutters or catches are again raised by riding up on the incline K.

V In the practical arrangement of the apparatus two inclines K are preferably employed, as illustrated in Figs. 3 and 4, one at each side of the supporters, and the catches or shutters have a T-head h, the two ends of which ride up on the inclines and prevent any lateral deflection which might. occasion a catching or jamming of the apparatus. .The shutters or catches in this practical form of' apparatus illustrated are also preferably provided with a slot or slots of different diame- 'terthat is to say, referring to Figs. 3 and 4, the slot 7t is of larger diameter at the bottom than at 77, at the top. Thus when the shutter or catch is elevated in relation to the supporters the cable, with its buttons or enlargements, is free to pass back and forth; but

when it is lowered, as in Fig. 4, the cable or wire D is confined in the narrow upper portion of the slot and the buttons cannot pass,

but will move the supporters along until the shutter or catch is again, elevated. The T- heads h of the shutters will rest on the supporterF when moved off the inclines K, thereby limiting the downward movement of the shutters, and at the same time the said T- 'heads will be held in position to cooperate with the inclines K to raise the shutters when the supporters are moved back to the starting-po'int.

Obviously the narrow portion of the slot may simply grip the cable or wire D whenever the shutter or catch is lowered with sufficient pressure to move the supporters backwardly catches orsh'utters on the supporters, it will be noted, are located at the end of the track or way, and consequently no looping of the hose-pipe or cable takes place in proximity to the carriage, but only at the end of the shop or track, as the case maybe, and thus only that portion of the hose-pipe or cable is moved which is necessary to extend from the end of the track or way to the carriage. Thus not only is the unused port-ion not subjected to wear and tear, but the carriage is left free from any complication due to the accumulation or festooning of the hose-pipe or cable about the same, advantages which will be at once appreciated by those skilled in the practical use of this class of apparatus.

Having thus described my invention, what 'I claim as new, and desire to secure by Letters Patent of the United States of America, is

1. In a travelingcrane or conveyer,the combination with a traveling carriage, a track or way and a series of supporters mounted on said track or way and a returning-cable connected with said carriage for simultaneous 1 movement therewith, means apart from said cable for loosely connecting said supporters and carriage for moving the same successively along said track or way, catches or shutters on said supporters for connecting said supporters to the returning-cable and a cast-off at the end of the track or way for disconnect ing said catches or shutters and cable; substantially as described.

2. In a conveying apparatus, the combination with a traveling load-carriage, a track or way, a series of supporters on said track or way and a flexible connection joining said supporters and the carriage whereby the supporters will be drawn along the track in one direction by the carriage, of a supporter-re turning cable moving in unison with the carriage, catches on the supporters cooperating with the cable to connect them when returning to initial position, and a cast-off for releasing said catches at the end of the track; substantially as described.

3. In a conveying'apparatus, the combination with a traveling load-carriage, a track or way, a series of supporters on said track or way and a power-conductor connected at one end with the carriage, and carried by the supporters between the carriage and end of the track or way whereby when the supporters are in proximity, the power-conductor Will be looped between them, of a cable moving in unison with the carriage for moving the supporters to one end of the track in advance of the carriage and means for connecting and disconnecting the cable and supporters; substantially as described.
