HOISTING AND CARRYING MACHINE.

SPECIFICATION forming part of Letters Patent l\Io. 641,508, dated January 16, 1906. Application filed August 81 1898- Serial No. 6 88,180. (No model.)

T at whom it may concern:

Be it known that LEWIS HARRIS, late a citizen of the United States of America, and a resident of Rome, Oneida county, New York,

did invent certain new and useful Improvements in Hoisting and Carrying Machines, of which the following is a specification.

The invention relates to hoisting and carrying machines; and it consists in the novel IO features hereinafter more fully pointed out and claimed.

In the drawings, Figure 1 is a front or side elevation of the machine, taken from the machine as illustrated in Fig. 2 when the same is reversed and supported on the ceiling or other elevated support. Fig. 2 is a bottom or lower side view of the machine looking upward when the machine is supported on the ceiling or other elevated support. Fig. 3 is a view taken from the opposite side of the machine from Fig. 1 when the machine is in the position stated in the description of Fig. 1. Fig. 4 is an end view of the car and a cross-section of the track. Fig. 5 is a view taken from the reverse side of Fig. 3. Fig. 6 is a front end View of the machine, taken from the left of Fig. 2. Fig. 7 is an end view taken from the right of Fig. 2. Figs. 8 and 9 are detailed views illustrating the worm-gear. Fig. 10 is avertical cross-section of the clutching mechanism, taken on line a a of Fig. 3. Fig. 11 is a sect-ion taken on line b b of Fig. 2, and Fig. 11 is a side view of the same. Fig. 12 represents a side view of the details of con- 3 5 struction of a friction-clutch for holding the load when the clutching mechanism is operated.

The hoist and carrier have heretofore been generally used in canning-factories where the steam processing is in chests or tanks open at their tops, through which open top crates are inserted or taken out containing the cans sealed, with their contents, the crates being of the size of the opening in the steam-chest, and these crates ordinarily contain from eight hundred to one thousand ordinary one-pound fruit-cans and their contents. The invention, however, is not limited to this particular use, as this system of hoist and carrier can be ap- 5o plied to any place or locality whereit is de- .the ceiling or overhead timbers or other elevated support. On rail 2, with flanges 3 3, Fig. 4, are mounted car-wheels or antifriction-rolls 4 between the car side walls 5 5, which wheels are mounted on the axles 6. (Illustrated in Fig. 4.) On the axles 7 7 of 7c the walls of the car are mounted grooved pulleys 8 8, Figs. 1 and 4. The car-wheels are placed on the flanges of the rail, and the car runs in either direction on the track at the will of the operator by the mechanism hereinafter more fully pointed out. The car is moved backward and forward on the track through the instrumentality of the rope 9, Fig. 1. The ends of the rope are secured to the sides of the car at 10 10, Fig. 1, and pass over the

grooved pulleys

11 and 11, supported by hangers 12 12 on the ceiling or otheroverhead support. The grooved pulley 11, Fig. 2, is mounted rigidly on the shaft 13, which latter carries two beveled friction-pulleys 14 14, rigidly secured thereto. The said shaft is mounted in hearings in the machine and is capable of end adjustment for throwing the face of the friction-pulleys on the shaft into and out of contact with the driving frictionpulley alternately. This alternate movement is accomplished by providing diagonal open ing 16, Fig. 2, in the shaft-bearing.

In diagonal opening 16 in the bearing 17 there is provided a projecting pin 15, secured to a sleeve or collar (not shown) on the shaft within the bearing. The sleeve 0r collar should be made to fit in a groove on the periphery on shaft 13 and so arranged that the sleeve has no end motion on the shaft, while the end of the sleeve or collar there is rigidly secured lever 18, so that when the lever is moved to the right or left the sleeve or collar carrying pin is worked in inclined groove 16 in the bearing, the incline being at an angle to the line of the shafting and also at an angle to the line of the rotation of the shaft, so that the shaft carrying beveled pulleys is moved endwise, so as to carry pulleys 14 14 into and out of contact with the face of the beveled pulley 19, which beveled pulley 19is mounted on the end of driving-shaft 20, so that the faces of these beveled friction-p ulleys can be engaged by alternating adjustment of shaft 13 through the operation of lever 18, already described.

The friction driving-pulley 19, mounted on the end of driving-shaft 20, which receives power through fly-wheel 21, is always driven in the same direction. On the driving-shaft 20 are mounted,loosely,two gears 22 22. On the inner vertical faces of the hubs of these two gears there is provided clutching mech anism, which in this instance is composed of notches 23 23, which are provided to engage corresponding notches on the vertical end of the rotating reciprocating clutch'24, which is held on the shaft 20 by a spline or feather 25 and rotates with the shaft and at the same time can be moved in the direction of the length of the shaft by lever 26, to which it is secured in a way not to interfere with its rotation, so that when lever 26 is moved to the right, Fig. 3, the vertical clutching mechanism on the hub of the clutch and the loose gear 22 are brought together and motion is imparted to the said gear and communicated to a corresponding gear on the shaft 27, lying parallel to shaft 20, and when the lever is moved to the-left of Fig. 3 the vertical cl utching mechanism on the end of the clutch and the loose gear are brought together and motion is imparted to gear 22, which communicates and connects with an intermediate gear, which will be more fully described later on. By sliding the clutch in either direction on the shaft 20 the ratcheted ends are brought into engagement with the corresponding ratchets on the hub for clutching the loose gears with the clutch which always rotates with shaft 20. By this alternating movement on the shaft a reverse motion is imparted to the parallel shaft 27. The

gears

22 and 31 do not engage each other, but power is communicated through intermediate gear 28, mounted on support 29, forming a part of the frame. The gear 28 meshes into gear-

wheels

22 and 31, and by this method a reverse motion is imparted to shaft 27 whenever the clutching mechanism is moved to the left to engage with gear 22, and when the clutching mechanism is moved toward the right into engagement with gear 22 a reverse power is applied to gear 31 on shaft 27, so that by reciprocating the clutch on the shaft an alternate reverse motion is imparted to shaft 27 through the mechanism already described. When the clutching mechanism is in the position shown in Figs. 2 and 3, the shaft 27 remains idle and shaft 20 continually rotates; but when the clutchin g mechanism is brought into engagement with either of the idle gears motion is imparted to shaft 27, and that motion is capable of being alternately reversed by shifting the clutching mechanism into and out of contact with the idle gears.

The shaft 27 is mounted in suitable bearings on the frame, and to this shaft is rigidly secured gear-wheel 31, which meshes into the intermediate gear 28, which also meshes into gear-wheel 22. A gear-wheel 3 l is also mounted on the same shaft and rigidly secured thereto, said gear meshing into gear 22 on the main driving-shaft. On shaft 27 a worm or spiral gear 32 is formed. (Best illustrated in Fig. 8.) In connection with this worm gear or shaft 32 agear-wheel 33 is rigidly mounted on shaft 34, so that whenever the rotation of shaft 27 is reversed the gear 33 is also reversed, and on the end of shaft 34 a grooved drum 35 is mounted and over which the hoisting-cable 36 is wrapped and on which it runs, cable 36 being secured at one end of the track, as best illustrated at 37, Fig. 1. This cable runs from this attaching-point over pulley 8, and between pulleys 8 8 on the cable the loose pulley 38 is placed, said pulley carrying hook 39, which is hooked into the load to be hoisted and carried. By shifting the clutching mechanism on the driving-shaft 20 the load can be lowered or raised at the will of the operator through the mechanism which has already been described. The load may be carried on the track in eitheir direction by operating lever 18 in either direction, by means of which friction-pulleys 14 14 can be alternately adjusted into or out of friction contact with drivingclutch 19 on the driving-shaft, and the movement of the car can be regulated in either direction and any desired location by operating lever 18 either to the right or to the left, depending on the direction in which it is desired to carry the load, and the moment the load arrives at the proper place by moving the friction-pulleys 14 14 out of contact with the driving friction-pulley the movement of the load can be arrested.

Automatic mechanism for arresting the movement of the load is also provided. This automatic mechanism consists in mounting on the end of shaft 34 the beveled gear 40, Figs. 2 and 3, which engages the beveled gear 41, rigidly secured to a stem provided with screw-threads at 42, which screw works in sliding stop 43. (Best illustrated in Figs.2 and 3.) This stop slides in guides of the frame, so that it may be driven in either direction by the screw-threaded stem into or out of contact with lever 26, which drives the lever carrying the clutch out of contact with the gear on the IIO driving-shaftand arrests the movement of the load. The stop 43 is moved in or out of contact with the lever 26 by the reverse mechanism already described.

The rope 9 should be wrapped on groovepulley 11 a sufficient number of times to secure proper friction on the pulley to move the load. The cable 36 must be secured on the drum 35 sufficiently strong to carry the load desired. A variety of changes will readily suggest themselves to one skilled in the art without departing from the spirit of the invention.

Referring to Fig. 12, there is illustrated the friction device for holding the load in an elevated position when the clutching mechanism is moved into the position shown in Fig. 2. To accomplish this, there is mounted rigidly on shaft 27, Fig. 12, a wheel which is illustrated in dotted lines in Figs. 2 and 3. On the under side of bearing 29 there is attached lever 2F) by means of a set-screw 29", which is tapped into bearing and so arranged that the lever can move freely on the set-screw, and in this instance the lever has a reverse spring-curve 29, the lower portion of the curve passing over friction-pulley 27 and has attached to its free end a cable 27 so located that it is within the reach of the operator. When it is desired to hold the load in an elevated position, the operator pulls down on cable 27, which brings the surface of the lever into contact with wood pulley 27 on the shaft, thereby creating sufficient friction to hold the load while the clutching mechanism for reversing the power is shifted.
