HOIST DERRICK Filed April 8, 1931 2 Sheets-$heet 2 Zlmnmtoz v PatentedNov. 15, 1932 PATENT oFF Ic FRANK n. STONER, or Mormon, MICHIGAN HOIST DERRICK Application filed April 8,

My invention has for its object to provide an exceedingly convenient and eflicient hoist derrick forraising and lowering heavy Weights and, .while hoisted, moving them from place to place as may be desired. .The invention particularly has for its object to provide a small derrick that is particularly convenient for use in factories and garages and the like, for lifting Within small spaces heavy Weights and moving them through confined areas, such as lifting transmission gear from within the closed body of an automobile and moving the gear while hoisted through the door of the car. The invention thus provides a readily movable derrick or crane having an adjustable beam that may be lowered and raised as Well as a hoisting mechanism, that operates at the end of the beam to raise and lower relatively heavy Weights. The derrick is also provided with wheels and casters or pivoted trucks and a base that extends well beneath the beam of the crane to afford stability and enable insertion of the base beneath low hanging parts, such as beneath the chassis of a truck or automobile.

The invention consists in other features and advantages which will appear from the following description and upon examination of the drawings. Structures containing the invention may partake'of different forms and may be varied in their details and still embody the invention. To illustrate a practical application of the invention, I haveselected a crane embodying the invention as an example of the various structures and the details of such structures that contain the i11- vention and shall described the selected structure hereinafter. It is understood that varia 40 tions may be made and that-certain features of my invention may be used to advantage Without a corresponding use of'other features of the invention and without departing from the spirit thereof. The particular structure selected is shown in the accompanyin drawings.

Il ig. 1 illustrates a perspective view of the crane hoist. Fig. 2 illustrates the hoisting gear and lockin dog that operates the drum of the hoist. ig. 3 is a front view of the 1931. Serial No. 528,512.

gear and drum of the hoist. Fig.4 is a side view of the hoist. Fig. 5 is a top view of the gear that adjusts the height of the crane and also the end of the beam with reference to its location above the base of the hoist. In the particular. formof construction shown in the drawings, the hoist comprises a base 1, a derrick 2 and an adjustable beam 3. The parts of the hoist are formed of chan nel and L-irons, in skeleton form, to produce gear rigidity of structurecomparable to the weight of the hoist. The baseis formed of a pair. of channel irons 5 that are bent substantially to form a V, the channel irons being tied together by suitable braces formaint'aining them in their relative positions. They are also riveted and braced tothe derrick 2. The more separated ends of the channel irons 5 are provided with flanged wheels 6, and the derrick and the smaller end of the base 1 are supported by a pivoted truck 7 having flanged wheels 8. At the. smaller end of the basel and at the lower end of the derrick 2, there is secured a bearing member 10 in Which the truck 7 is swiveled. For convenience of handling the hoist and conveyance of articles supported thereby, a handle bar 11 ispivotallylconnected to the truck 7. The handle bar 11 is preferably bent to form the portions 12, 13, and 14 that o are inclined relative to each other in order that the handle bar 11 may be confined within a small floor area'and in close proximity to the base 1 andthe derrick2 ofthe hoist, substantially as shown in Fig. 14. Preferably the derrick 2 is provided with a suitable latch 15 for securing the handle in position. Preferably the handle bar 11 is provided with a cross bar 18 and the uprights of the derrick 2 are provided with a pair of brackets 19 to prevent angular movement of the truck 7 when the handle is secured by the latch15. When the handle bar 11 is secured in position by the latch 15, the bar18 engages one of the rear edges of the bearing member 10 which extends across the rear or smaller end of the base 1. This locks the truck 7 from angular movement relative to the base 1 and thus provides a means for securing the base in position and prevents. lateral swinging of the truck by reason of any pull on the beam along a line inclined to the vertical andin a direction towards the lateral sides of the base 1. The brackets 19 cooperate with the cross bar 18 to rigidly secure the handle bar 11 in its non-rotative position.

The derrick 2 is secured between the ends of the channel bar 5. The derrick has suitable hoist mechanism for manipulating a cable that extends over pulleys or sheaves located in the end of the beam and over pulley blocks having suitable means for connecting the hoist with the weight that is to be lifted. In the form of construction shown, a suitable drum 25 is rotatably supported in the derrick 2, on which may be wound a cable 28 that extends to the outer end ofthe beam 3. The

drum 25 is supported on a shaft 26 that is rotatably supported in theparts of the plane of the derrick 2 and the beam 3 is oscillatively supported on the shaft 26. Preferably, the shaft 26 is rotatably supported in bushings 27 that extend through the frame of the derrick 2 and the side bars of the beam 3. The bushings 2'? thus operate to pivotally support the beam 3 on the derrick 2 and prevent any binding on the shaft 26 by reason of the pull or tension of the cable 28 and the weight that may be supported at the end of the beam. The drum 25 is rotated by the gear wheels 30 and .31 that may be operated by a suitable crank 32 to produce rotation of the drum 25 and to consequently wind and unwind the cable 28.

In order to prevent unwinding of the cable 28, the drum 25 may be secured as against rotation by any suitable brake mechanism that may be manually controlled. In the particular form shown, a dog 35 is pivotally connected to theframe of the derrick 2 and is adapted to engage the teeth of a ratchet 36 that is connected to the shaft26. As the drum 25 isrotated to wind up the cable 28 on the drum, the dog rides on the ratchet wheel 36 and on cessation of the lifting rotation of the drum 25, the dog will engage and hold the drum and thus hold the weight in its raised position. The weight may be lowered by reverse rotation of the crank 32 and the drum 25 when the dog is manually releasedfrom the ratchet wheel 36.

The beam 3 extends over the base 1 and is formed of a pair of L-bars 38 that are interconnected and braced by suitable cross members 39. The elevation of the outer end of the beam 3 is adjusted by means of a telescoping rod 40 that is connected to the upper end of the derrick 2 and to the outer end of the beam and consequently the distance between the derrick 2 and a vertical line extending through the outer end of the beam 3 will be increased or decreased as adjustment in the elevation of the outer end of the beam is made. The telescoping rod 40 is formed of. a sleeve 41 and a screw 42.

The sleeve 41 has female threads and the shortens the length of the telescoping rod 40 and thus draws the upper end of the beam 3 towards the upper end of the derrick 2 and, since the point of connection of the telescoping rod 40 with the derrick 2 is above the pivot point of connection between the beam 3 and the derrick 2, the beam 3 is raised and the distance between .the vertical line, through the outer end of the beam 3, and the derrick 2 will be decreased. If a weight is swung from the end of the beam gill bring the weight towards the derr1c The telescoping rod 40 is bifurcatedat one end, it being provided with arms 43. The ends of the arms 43 are located on the outsideof the L-bars 38 and are pivotally connected thereto by means of the pin 44. A yoke 45 is connected to the threaded rod 42 and to the upper end of the derrick 2 by means of the shaft 47. The threaded rod 42 is rotatably supported in the yoke 45 and bevel. gear wheels 48 are connected, one to thethreaded rod 42 and the other to the shaft 47. They intermesh within the yoke .45 to produce rotation of the threaded rod 42 by the rotation of the shaft 47. The shaft 47 may be operated by means of the crank 32 that may be placed on the squarevend 49 of the shaft. Preferably, the shaft 47 is pivotally supported in a pair of bushings 50 that extend through the frame of the derrick 2 and the yoke 45 to prevent the pulley of the telescoping rod-40 from binding the shaft 47.

The outer endof the beam 3 is provided with a pair of sheaves and the cable 28 extends from the drum 25 over the sheaves ,means of the cable and, if desired, it may be further raised by shortenin the tele scoping rod 40. The height of the outer end of the crane mayalso be readily adjusted by' shortening or extending the length of the telescoping rod.

The construction may thus be readily shifted from point to point and the base may be located beneath an article and thus afford an overhanging crane that may be conveniently used in shops for manipulating heavy weights within relatively small heights.

I claim:

1. In a hoist, a base part having a swiveled truck and supporting wheels, a derrick, a cable suspendedfrom the end of the beam,

a shaft supported in the derrick'and for oscillatively supporting the beam and rota- 'tively supporting the drum, sleeves surrounding theishaft and extending through the derrick and the beam for preventing binding of the shaft by the pressure transmitted through the beam, and means for changing the angle between the beam and the derrick.
