OVERHEAD CARRIAGE AND HOIST FOR MILK CANS Filed April 15., 1949 '2 Sheets-Sheet 2 Fig.4.
Inventor Patented Aug. 29, 1950 UNITED STATES I PATENT OFFICE OVERHEAD CAIRRIAGE'ANDHOIST FOR MILKCANS." Benson V. Culp, West I Application April;l5,1949,-Serial No'.'8 7,692 j I I zoiaims. (o1. 212 134)" The present invention relates to new and useful improvements in overhead carriages and hoists and more particularly to a device of this character for hoisting milk cans into and out of a cooler.
An important object of the invention is to provide a power operated hoist for raising and lowering the milk cans and mounting the hoist on a carriage supported from a overhead track to facilitate movement of the cans into and out of position with respect to a milk cooler.
A further object of the invention is to provide a novel hoist mechanism including a hoisting chain and a belt and pulley driven sprocket for raising and lowering the chain with brake means for holding the pulleys from idle rotation and to hold the can in a raised position.
A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational view;
Figure 2 is a top plan view;
Figure 3 is an end elevational view;
Figures 4 and 5 are enlarged transverse sectional views taken respectively on the lines 4-4 and 5-5 of Figure 2, and
Figure 6 is an enlarged perspective view of the brake.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a carriage generally which comprises a platform 6 supported by hangers I at each end having wheels 8 at their upper ends for traveling on an overhead track 9.
An electric motor I is mounted on one end of the platform 6 to the shaft of which a relatively small pulley II is secured driving a relatively large grooved or V-pulley |.2 by means of a belt I3. The pulley I2 is secured to one end of a shaft l4 journaled at the opposite end of platform 6 from motor I0 and a relatively small pulley I is secured to the other end of shaft I4 driving a larger pulley It by means of a belt H, the pulleys l5 and i6 and belt I! being positioned at an opposite side of platform 6 from pulleys I l and I2 and belt 13.
The pulley I6 is secured to one end of a shaft I 8 journaled on the platform 6 substantially centrally thereof and a sprocket I9 is secured to shaft I8 over an opening 20 in the platform. A chain 2| is trained over sprocket [9 with one end of the chain attached'to platform 6 and the other end of the chain extending downwardly and attached to a pair of tongs or hooks 22 for engaging the handles 23 at the opposite sides of the milk can 24.
A brake arm 25 is pivoted at one end on the platform 6 by means of a pin or the like 26, the arm 25 projecting outwardly from one side of the platform and formed at its outer end with a brake block 2'! provided with a V-brake shoe 28 for seating in the groove of pulley l2. The brake shoe 28 is held in engagement with the pulley by means of a coil spring 29 attached to arm 25.
A switch 29 for motor In is suspended from the carriage by an electric cord 30 within convenient reach by an operator to drive shaft [8 at reduced speed by the belts and pulleys whereupon to rotate sprocket l9 and raise and lower chain 21 and the milk can 24 attached thereto. The brake shoe 28 holds the pulleys from idle rotation by reason of the frictional engagement of the brake shoe 28 with the pulley l2 and also holds the can in a raised position when the motor is idle.
A pull rope or cable 3| is also attached to carriage '5 by means of which the carriage may be manually pulled back and forth on track 9 into a position for raising and lowering the milk cans into a conventional milk cooler 32.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. A can hoist and carriage comprising an overhead track, a carriage mounted for traveling on the track and including an elongated platform having a center opening, a transverse shaft journaled on the platform over said opening, a sprocket secured to the shaft, a chain trained on the sprocket and extending downwardly through the opening for hoisting an object attached to the lower end of the chain, a motor mounted on one end of the platform, a transverse shaft mounted on the other end of the platform, a belt and pulley reduction drive means from the motor to the last-named shaft and on one side of the platform, and a belt and pulley redrigid gin drive from the last-pained to the shaft and on the other side ofthe platform.
2. A can hoist and carriage comprising an over,-, head track, a carriage mounted for traveling on the track and including a platgorm an, opening, a shaft journaled on thep1atform,l a;
sprocket secured to the shaft, a chain traiged qn, 15 Number.
the sprocket and extending downwardly through the opening for hoisting an objegtgattachemto the lower end of the chain, a motor mounted on the 5 in the groove of the pulley, and spring means holding the brake shoe in braking position.
