Application October 22, 1947, s 'erial No. 781,271

My invention relates to hoists, and more particularly to a hoist for lifting the licker of a cotton card or other roll shaped member.

When it becomes necessary to lift or remove the licker of a cotton card, two or more men are required to manipulate the licker manually. It is therefore an important object of this invention to provide a hoist for the lickers of cotton cards which requires only one operator.

A further object of the invention is to provide} a licker hoist which straddles the frame of a card, adjacent to the licker and has lifting means disposed directly over the licker. V A further object is to provide a hoist of the above mentioned type having means to support the licker in a horizontal raised position after it has been lifted from the card.

, A still further object of the invention is to provide a device of the above mentioned class which is extremely simple and sturdy, portable, and well adapted for inexpensive manufacture.

Other objects and advantages of the invention:

will be apparent during the course of the following description. 7

"In the drawings, where for the purpose of ilends include upwardly converging sides [3, pref erably formed of angle iron, and rigidly conhosted at theirtop ends, and bottom transverse horizontal bars, rigidly connected to the bottom ends (of thesides. .13. ..The. top. ends of the 2 Claims. (01. 214565) triangular frame sections II and I2 are rigidly connected by a top horizontal longitudinal beam,

15. Parallel longitudinal braces 16 are disposed a short distance beneath the beam 15, and parallel thereto, and rigidly connected at their opposite ends to the sides l3 of ends H and I2. Short diagonal corner braces I! are provided, and are rigidly secured to the beam l5 and sides 13.. beam l5 and longitudinal braces l6 form. a tophorizontal frame section, rigidly connecting the ends H and i2. Disposed near the vertical cen-' ter of the frame I0 and rigidly connected at its ends to corresponding sides l3 of the frame sections or ends II and I2 is a longitudinal horizontal angle member or lower beam IS. The ends II and I2 are provided at their lower cor-' here with wheels or casters l9."

Arranged below the longitudinal braces l6 and above the lowerbeam I8,'and parallel to the samefis a longitudinal horizontalrotatable shaft 2?), upon which grooved pulleys'2l are rigidly mounted for rotation therewith. The pulleys 2| are disposed near the opposite ends of the shaft 28 and inwardly of and near the ends H and l2.

The shaft 20 is arranged directly beneath the top beam I5, and is at thetransverse center of the frame [0. One end of the shaft 26 is journaled in an opening at the center of a horizontal support bar or brace 22, rigidly connectedto the sides I3 of end H. A similar horizontal support bar or brace 23 is rigidly secured to the outer sides of the sides l3 of end l2. The braces 22 and 23 are arranged in alignment. Rigidly mounted upon the outer side of the brace 23 is an outward 1y offset support bracket 24, including inner portions or feet 25, rigidly connected to the brace 23. The brace has an opening 26 rotatably receiving the end of shaft 20 therein, andthe opening 26" is in axial alignment with an opening 21 in the bracket 24. The endof the shaft 20 extends through the opening 21, as shown. Cotter pins 28, or the like, and ajwasher 29 are provided to prevent axial 'orendwise movement of the rotatable shaft 20. A vertical passage 30 is formed betweenthe oifs'etbracket 24 and brace 23. Rigidly' mounted upon the shaft 20 for rotation therewith, and disposed in the passage 30, is a gear 3|, having an inner annular flange provided with ratchet teeth "32, and formed integral with the gear. The gear 3| is in meshed engagement with a small drive gear 33, rigidly mounted upon a short rotatable shaft 34'journaled in openings inthebrace 23 and offset bracket 24. The shaft 34 is provided with a crank or handle 35, rigidly connected therewith, and arranged outwardly of 3 the offset bracket 24. A pawl 36 is pivotally mounted upon the end |2 above the gear 3|. This pawl is adapted to engage the ratchet teeth 32 for preventing rotation of the shaft 20 in one direction. A hand lever 31 is pivotally mounted upon the end l2 at its side opposite to the pawl 36, by means of a pivot pin 38, or the like. The inner end of the lever 31 extends near the pawl 36 and is disposed at the inner side of the same, and is provided with a laterally projecting pin 39, to engage beneath the pawl and lift the same out of engagement with the teeth 32. The pulleys 2| have chains permanently connected to them, and these chains 40 engage in the pulley grooves and are adapted to be wound upon the pulleys. The chains 40 are preferably of the proper length to be wound about the pulleys once, but they may be longer. The chains 40 are provided with circularly curved lifting hooks 4| at their free ends.

Disposed directly beneath the pulleys 2| and pivotally connected at one end to the lower longitudinal beam l8 are horizontal support arms 42. These support arms are adapted to swing horizontally, and are connected to the beam |8 by bolts 42'. The support arms 42 are preferably formed of angle iron. Each of the pivoted support arms 42 has disposed upon its top side a V- shaped member or bearing 43, rigidly secured in place by means of welding, or the like. The bearings 43 are in vertical alignment with the chains 49, as the same are unwound from the forward sides of the pulleys 2|, see Figure 2. Rigidly mounted upon the forward sides l3 of ends H and I2 and projecting longitudinally inwardly from such ends are short horizontal stationary support arms 44. Diagonal braces 45 are rigidly secured at opposite ends to the support arms 44 and adjacent sides I3, and these diagonal braces serve to strengthen the support arms 44. When the pivoted support arms 42 are swung outwardly and at right angles to the beam l8, the outer ends of the arms 42 engage upon the outer ends of the arms 44, and are supported thereby, Figures 1 and 3. The inner vertical webs of the angle sections forming the arms 42 are notched at their forward ends, as shown at 46, to provide clearance when the arms 42 are swung outwardly toward the ends H and l2, Figure 3.

The operation of the licker hoist is as follows:

The hoist is wheeled into position with relation to the frame 48 of a cotton card, and the hoist is adapted to straddle the end of the frame 48 adjacent to the licker 49 supported thereby. The forward side of the hoist, remote from the lower beam H3, is open, and this facilitates moving the hoist inwardly with respect to the card frame 48 until the rotatable shaft 20 is directly over the licker 49, Figure 6. Since this side is open, the comb drum A and the comb belt B of the card, and associated elements, may enter the frame, passing beneath the brace l6, and between the short arms 44. With the hoist in this position, the hand lever 31 is depressed for lifting the pawl 36, and the chains 46 are cranked downwardly so that the hooks 4| may engage beneath the shaft 59 of the licker. The tops of the bearings which hoid the shaft 50 are of course removed to free the shaft. The pivoted support arms 42 are swung outwardly toward the adjacent ends II and I2, and assume positions shown in dotted lines in Figure 3. The crank 35 is then turned in the direction for winding the chains upon the pulleys 2| and the licker 49 is raised from the card frame 48. Since the arms 42 are swung outwardly, the

licker may pass upwardly and between the same until the shaft 50 is slightly above the bearings 43. When this occurs, the arms 42 are swung inwardly to their positions of Figure 1, and the licker is again lowered until the shaft 50 is seated in the bearings 43. The hooks 4| may then be disengaged, and the hoist supporting the licker may be pushed to the desired location. The pawl 36 engaging the teeth 32 prevents unwinding of the chains 40 while they are supporting a load. Obviously, the hoise may be used when it is desired to place the licker back upon the frame 48 of the cotton card.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:
