OABLEWAY CARRIAGE.

Application filed February 28, 1925.

To all 107mm it may concern:

Be itiknown that I, KnXNs'rH B. NOBLE. a citizen of the United States, and a resident of Hartford, in the county of Hart iord and State of Connecticut, have invented new and Improved Cableway Carriages, of which the following is a specification.

My invention relates to the class of devices that are employed for carrying loads to diti'erent positions along a cableway and for elevating and lowering said loads ir different positions in which the cable may be placed, and an object of my invention, an'iong others, is to provide a device of this class that shall be simple in construction and particularly eiiicient in operation, simplicity in operation also being insured.

tine ii'orm oi device embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation of my improvec cableway carriage, aportion of the load suspending and releasing mechw nism being shown in section.

Figure 2 is a view in side elevation of a portion of the load suspending and releasing mechanism looking in a direction at right angles from the point of view or Figure 1.

Figure 3 is a view in side elevation of a portion of said mechanism illustrating the operation of the levers in releasing a load.

My improved apparatus contemplates a structure that may be employed for use on a cable or rope irrespective of the directio in which said cable or rope may be inclined. or whether it be placed in a level position, the device being so arranged and constructed as to involve extreme simplicity in its operations, all of which operations, including; movement of the carriage to any desired position, the raising of the load thereon, with the locking thereof in a raised position. and the unlocking of the; same, are accomplished by means of two lines or cables extending from opposite ends of thecarr-iae'e and wound upon non-reversing rotatable drums, and by the use simply of the customeryc'lutch "and brake for the drums of a hoisting device of ordinary and well'known construction.- Aside from such parts any other devices, cables, stops, springs or other adgusteble e rie-re tel lPPi5i aar .pia'ay lie-secured; Fi

lockin or raisin the load at an I selected point are not required.

In the accompanying drawings the numeral 5 indicates a cableway that may be susiended in any ordinary and usual manner and along which the carriage is moved for the purpose of locating the load in any desired position. This carriage comprises two side plates 6 that are suitably spaced apart to receive the cable 5 between them, suitable spacers being employed and the parts being secured together as by bolts 7 (arrier sheaves 8 are rotatably mounted between the side plates at the upper edge of the carriage, said sheaves being adapted to roll along the cable 5, and a hoisting sheave 9 is also rotatablymounted between the plates at a point below the cable 5, and as illustrated in Figure l 01'. the drawin A main carriage cable 10 is secured to the carriage at its front end, said cable passing to and being wound upon one of the drums of any suitable hoisting apparatus common to devices of this class for moving the carriage along the cable'way This hoisting apparatus may be comprised of two nonreversing drums, manually or power operated, as may be desired, mounted upon a suitable base and relatively located in a mannerthat will be readily understood by those skilled in this art, and for which reason a showing thereof is omitted herein, said drums being provided with means for in dependently rotating them, to permit either to remain at rest independently of the other and to retard their free rotation in a manner common to apparatus of this kind. Such an apparatus is illustrated in my C0-- pending application, the oath in which bears even date herewith, and to which reference may be had for a more thorough understanding of the apparatus if desired.

An operating line 11 extends to and-is wound upon the other drum of said hoisting apparatus for hauling purposes and said line extends over the sheave 9 and downwardly between the side plates 6 through the bottom of a yoke 12, through the top of a housing 13 for a load. supporting catch block 14, and through said catch block to which it issecured in any suitable manner, as by means of a Wedge in a recess in the supportheld therein by means of a clampingscrew 1.5, through which s ;rew;tl 1e line extends and to the free end of which a hook the drawings. This catch block may be of a size and weight to serve as a fall line ball dotted lines in Figure 1. Only the carriage,-

however, is shown in dotted lines to indicate this inclined position, but in such position the operating and load supporting mechanism will be suspended vertically, asv

shown in full lines in this figure, although in a little different position from that shown.

The housing 13 has supporting lugs 17 on opposite sides thereof and supporting rods 18 secured to said lugs extend through guide lugs 19-20 projecting from the side of the yoke 12, the rods 18 being provided with any suitable means, as nuts in the construction herein shown, to limit the downward movement of the housing 13, Locking levers are pivotally supported in lugs 21 onopposite sides of the housing 13, these levers comprising load supporting latches 22 at their lower ends and latch disengag ing cams 23 at their upper ends, said cams being located inposition to make contact with the end of the yoke 12 when the housing 13 is raised, as by a pull upon the operating line 11. Said cams are offset, as shown in Figure 2 of the drawings, so that they will not interfere with the operating line 11 in its movements through the hole in the top ot'thc housing 13 and said cams. are oi; such weight with respect to the latches 22,-

and areso disposed relatively to said latches, that a slow swinging movement thereof is obtained, as compared with the movement of the catchblocl-r from within the housing, so that when the operating line 11 is loosened to permit the catch block to fall the latter will readily, pass its lower edge below the engaging portions of the latches 22 before the latter have'tinie to swing to their closed and locking posit on. 4 s

It \Vlll'bG understood that the cable 1.0 is

. eassed around asheave and from thence in ing line 11, with or without a load suspendedtherefrom, or a haul upon the main carriage cable 10. If the load is in its lowered po sition the drum upon which the cable 10 is wound is held against rotation thereby resisting the pull upon the carriage as the load is being raised by a haul upon the op erating line 11. A continued haul upon the operating line, after the load has been raised and locked in its raised position, will serve to move the carriage in one direction, the drum upon which the cable 10 is wound be ing released for such purpose and the drum upon which the line 1]. is wound being rotated. A movement 01"- the carriage in the opposite direction may be obtained by reversing this operation of the. drums. lVhen the carriage has been placed with the load in the desired position the release of the load supporting catch block is effected by a haul upon the line 11 through its operating drum that raises the housing 13 and the cam lever locks carried thereby, the latter into ongagement with the yoke 12 whereby said lever locks are opened as shown in Figure 3 of the drawings. The operating line being now quickly released by a release of its operating break the catch block quickly passes its lower edge below the engaging portions of the supporting latches, and the load is lowered by a breaking action upon the drum. When the load is raised, as here inbe'fore described, the latches will be engaged by the catch block and opened suf fieiently to permit its passage and said latches will then automatically close to catch and hold said block.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other i'neai'is" said carriage, a catch blo'ck'semii'ed to said line'and relativelyinnnovablc thereoi, amen'iber to engage said block to retain it"in a raised POSIUOYLHYQEHYS locates in the path of movement or said member to-engage it" when; moved and idisengage' it. from said bloek a11d means to engage said member when it is stationary to engage it with said block.
