SPEGIFIATION forming part of Letters Patent No. 657,598, dated September 11, 1900. Application led August 8, 1898. Serial No. 688,129. (No model.)

To @ZZ whom it may concern,.-

Be it known thatLEWIs HARRIS, deceased, late a citizen of the United States of America, and a resident of Rome, Oneida county, New York, did invent certainnew and useful Improvements in Hoists and Carriers, of which the following is a specification. f

The invention relatesto a hoist and carrier; and it consists in the mechanism hereinafter pointed-out and claimed.

Figure 1 is a side View of the operating mechanism of the apparatus. Fig. 2 is a side View of the apparatus of Fig. 1 looking at the opposite side thereof. Fig. 3 is a top View of the machine in position for operation, portions of the frame 'being shown in cross-section. Fig. 4 is an end view of the drum with the gears removed, showinga side view of the friction-band and the lever for operating the same. Fig. 5 is a vertical central section of the gear-drum and a full view of the shaft and mechanism for clutching the drumthe friction-band being shown in cross-section on the drum. Fig. 6 is a side elevation of the Inachine. Fig. 7 is an end View of the car, the rail or track being shown in cross-section. Fig. 8 is an end view taken from the left of Fig. 2, illustrating modilications of structure from that illustrated in Fig. 2.

In the'drawings the several reference-11u-v merals refer to correspondingY parts in the several views.

While the machine permits of several structural changes which may occur to one skilled in the art of manufactureof such machines, yet the best form in which the invention has been practiced is inthe details of construe` tion hereinafter more fully pointed out and claimed.

A track 1 is provided suitably supported In this instance the in an elevated position.

track is composed of I-beam steel. On the lower flanges 2.2 wheels 3 3 are mounted on on the car is desired to be moved, and the cable passing over one of the grooved pulleys 6 receives carrying-pulley 8, passes over the other .pulley 6 of the car, and is secured to and wrapped on cable-drum 11, which has on one edge liange 12 and on the other end has a frictionband 13. Cable-drum 11 is mounted to run loosely on shaft 14, which passes through hub l5 of the said drum, the shaft being mounted in suitable frame 1G, secured to stationary supports. On the inside end of drum 11 a beveled edge 17 is provided, which ts over the beveled surface 18 of drum-head 19, which in this instance is made of wood to increase the friction. The drum-head 19 is splined rigidly to the shaft 14 and iits into flange 20 of gear-wheel 21 and is rigidly secured thereto. The beveled overlapping rim of the cable-drum receives the beveled surface of the head, the two when Abrought in contact forming a frictionsurface to engage each other and forms the clutchingmechanism for controlling the drum. The clutching and unclutching mechanism' for bringing the surfaces into or out offriction engagement with each other is' operated by incline shoulder 22 on shaft 14 and loosely secured thereto. Rigidly secured to shaft 14 is a flange having on its side an incline shoulder 23, which is in contact with shoulder 22. Alever 24, depending from theshoulder22, operates the latter, so that t-he drum is moved into or out of contact with the friction-head, either securing the drum to the friction-head or withdrawing it from contact therewith. When the cable-drum is loose from the frictionhead, the load may be lowered through the operation of gravity. For regulating or controlling the motion of the drum band 13 is provided, which is rigidly secured to the frame at 27 and partially surrounds the drum and is attached at 29 to shaft 30. Lever 2S is rigidly attached toshaft 30, so that by drawing down on cord 31 the speed of the drum is controlled by the operator-by friction engagement of the band with the drum, which is best illustrated in Fig. 4 of the drawings.

Power is imparted to the machine through fly-wheel 32, (best illustrated in Fig. 3,) which IOO carries small driving-gear 34, splined to the shaft 33-a-ndvmeshing into the drum-gear The gear-35 on the shaft 33mesh'e's ihtgear is applied to shaft 37.

36, splined to'shaft 37,'mounted on the frame 16.' Through these gears a reversed motion For reversing the rotation-of the parts shaft 38 is provided,mountled to rotate in brackets or standards-39 39,

, friction-drums 35a on shaft 33 and 36 on shaft 37 for reversing the rotation `of the shaft 38, on which is splined grooved-face v,rope-pulley 42, which drives rope 43, which isv attached at opposite sides of the ear 44 at 45 45, the rope extending over idle pulley-46' and groove-pulley 42, to which it is held. The rock-shaft 38 is operated to throw the drum 41 4into or out of engagement with frictiondrums 35L or `36a through the medium of arm Rigidly fixed orl 47, mountedon shaft 38. y rigidly secured'to arm 47 is lever 48. Friction-drum 4l `is alternately brought into engagement with drum 35a or 36a, and by this mechanism an alternate reverse motion is imparted to shaft 38 and pulley 42 and to car 44 through the rope and the mechanism driven by themachine'ry already pointed out. If the operator desires to hoist the load into an elevated positionghe moves the lever 24,v thereby driving the drum onto the drum-head into friction therewith and connecting mechanism which drives the drum, wraps the cable on the drum, and liftsthe load. If theoperator desires to lower the load, he operates level` 24 in away to move the drum out of friction-contact with the head, and at the same time the load will drop by gravity. Whenthe load is hoisted to vthe required height, the operator moves lever 24 to discon- -nect the drum from the gear and pulls ou cord 31 and applies the pressure of the friction-band 13,/andthus holds the load and drum. When the load is at the requisite height and it is desired to carry the same' either to or from the machine, it is accomplished by operating lever 48 in the direction to which the load is desired to be transferred. By the movement of the lever either to the right or to the left the friction-drum 42 is thrown into contact either with drum v35a and out of contact with friction-drum 36a, or it is thrown out of contact with friction-drum 35a and into contact with friction-drum 36a,which moves grooved drum 42 or reverses the same, so that the load can be driven out or drawn in at the will of the operator. I

In the mechanism illustrated in Fig. 8 the grooved-face pulley 42, which carries and drives rope 43 for operating the car in or out, is mounted on a journal supported on the framey at 40, Fig. 2, so that the center of the pivotal point of the swinging arms 39 and the center of the journal are the same, and

on this-journal gear 42ais -mounted,1which is rigidly-secured tof groove-pulley 42',-b'nth running together freely on'the journal, which su pports them. On the end of shaft 38, which carries the wood friction pulley, which is mounted-to be swung into cont-actwith'the two .friction-rollers forreversing the' movement of une pai-ts, ,gametes-14mm mounted, .splined to the shaft. The gear 42b meshes into gearl 42fand imparts to it and thegroovepulley an alternate rotary motion` when the wood friction pulley or drum is swunginto `or` out of `eontact with the two friction rollers ,or drum yfor reversing vthe movement of the parts. Vlfy this ari-angement.` the location of the groove-pulley 42 is sustained on theframe in a given space land not moved with the friction drum.V By this arrangement. the sametesion isalways maintainedon the rope or cable for moving the car. l ,i

g Itis obvious that linstead of using the gearwheels already described pulleys and belts vmay be substituted in their place and accomplish the same end. The gears, however, are preferred because of their positive engagement and freedom from slipping, which might occur if belts were used.
