FRED (.7.l FANTZ, OF PORT ARTHUR, TEXAS, ASSIGNOR TO THE TEXAS COMPANY, A CORPORATION OF TEXAS.

BARREL-'HOISTING APPARATUS.

Application led December To all whom t may concern Be it known that I, FRED C. FAN'rz, a citizen of the United States, residing at Port Arthur, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Barrel-Hoisting Apparatus, of which the following is a specification.

My invention relates to hoisting apparatus for elevating and loading-barrels, bales or packages and particularly to such as is adapted for loading heavy barrels or bales into freight cars.

One object of my invention is to provide a simple, durable and efficient hoist of the aforesaid character that shall be power operated, readily portable, and capable of continuous and rapid operation.

It is a comparatively simple and easy matter to load barrels into box cars from a loading platform substantially flush with the car floor up tothe point when a single tier `of barrels lcovers the entire car oor. It is then diicult and a relatively slow process to raise barrels of oil or other heavyl barrels or bales onto the upper tier.

According to my invention `I provide a simple hoist which is adapted to raise vthe barrels, bales or the like, very quickly and easily, and, if desired, at a, continuous and uniform rate to the level of the upper tier or to some other predetermined height thereby decreasing the cost and increasing-the speed of loading. The apparatus is also well adapted for unloading and for various other purposes.

In order that my invention may be thoroughly understood I will now proceed to describe an illustrative and preferred embodiment of the same in the following specification, and will then point out the novel features in appended claims:

Referring to the drawings:

Figure 5 is a sectional-detail of the same apparatus drawn to a larger scale.

Figure 6 is an enlarged sectional detail of a clutch mechanism embodied in the apparatus.

In the drawings, like parts are designated by the same reference characters throughout all the figures. Y

The apparatus constitutes a self-contained unitary structure of portable character and comprises a supporting structure embodying a pair of A-shaped endframes 10 and 11 which are interconnected at the rear by

rods

12, 13 and 14 and by cross bars 15. supporting structure is so arranged that the lower front thereof is free and open to permit of an unobstructed introduction of a barrel or the'like at the floor level while The to allow the discharge of the barrel at a higher level. A rotatable drum 16 is mounted in suitable bearing brackets 17 which are offset so that the 'drum 16 is entirely outside of the space between the A frames and consequently does not interfere with the up and down sliding' motionV of a vertically movable hoisting bar 18. lAs clearly shown in section in Figures 2 and 5 this bar is relatively thin in respect to its width and terminates at each end in blocks or projections 19 which lit into and are adapted to slide in channels 20 formed 'in the front sections ,ofthe respective A-frames 10 and 11. These sections may conveniently be formed of channel-irons so as to form the track or channels in 'which the blocks 19 run from the bottom to the top of the sup- /porting structure. The bar 18 may be provided with rollers 19a or other friction reducing devices at the point of contact with guides 20.

The hoisting bar 18 is connected at its respective ends to hoisting cables or chains 21 which extend upwardly in the channels 20 over sheaves or pulleys 22, on a transverse'shaft 23 at the top of the frame, and downward at the front of the apparatus onto the drum 16 to which they are attached, as clearly indicated in Figure 4. The arrangement of parts is such that when the drumV is turnedin one direction the chains or cables are wound thereon and the hoisting rod or bar 18 is lifted, this motion being guided by the channels. The weight of the bar is sufficient to descend by gravity (fai) and rotate the drum in the opposite direction unless it is suitably restrained.

The drum has a shaft extension 24 which is provided with a gear wheel 25 in mesh with the pinion 26 on a driving shaft 27. This driving shaft has at its opposite end a driving pulley 28 which runs 'idly on the shaft except when engaged by a clutch, controlled and operated by a hand lever 29, which is interposed for the purpose ot connecting or disconnecting the drum to or from the pulley 28 at the will of the operator. rlhc clutch mechanism may be of any suitable type. For example, it may comprise a cone friction clutch such as is illustrated in detail in Fig. 6 wherein the driving pulleyV 28 is shown as being keyed to a driving clutch member 54 which runs idly on the shaft 27. A driven. friction block or cone 55 vis secured to a brake wheel 56 that is pinned to the shaft 27. The hand lever 29 is arranged to operate a clutch screw 56 which may work longitudinally through a stationary nut bearing 57.` By means of the lever 29 and screw 56, the clutch cone 55 may be brought into driving engagementI` nected by a beltm31 to the pulley 28.

In the arrangement illustrated the motor and a control switch 32 are mounted on the supporting structure and a'current conthe apparatus.

The barrel hoisting mechanism perse withl which my invention is particularly concerned, will now be described. -It consists of a pair of spaced channel guides 36 which ext-end in an inclined plane across the lower back corneroi' the frame between the cross bar 13 and a cross tie 37 which is disposed between the rod 14 and the front of the apparatus. The arrangement of the guides is clearly shown in Figures 2 and 4.

' These guides 36 are adapted to receive and position a pair of flexible hoisting members or chains 38 having their upper ends secured to the cross member 13 at the top refranes to form a cradle or sling which is adapted to receive a barrel B, bale or other article to be hoisted. These llexible supports are spaced so as to engage a barrel, for example, not far from its ends. Oi course, any number oi flexible hoisting members may be used. The arrangement is such that when the hoisting bar 18 is lowered to the. bottom ot .the channels 20 and rests upon the floor or ground, the barrel may readily be rolled over it into the. cradle, it already having been pointed out that the supporting structure has its lower front portion entirely free and unobstructed for this purpose.

Assuming that the motor is in operation, it is then only necessary to manipulate the control lever 29 to throw the clutch in order to cause the drum to rotate and hoist the bar 18 which carries with it one end ot the flexible hoisting cradle 'or sling, thus elevating the barrel and finally discl'iarging it through the unobstructed rear portion ot the structure at the level desired. A pair of ways or discharge chutes 39 are hinged to the cross bar 13, as shown in Figure 3, and may be either folded up in the position ot Figure 1, or let down in a horizontal position as shown' in Figure 2. ln the latter position, the chutes 39 are adapted to receive and deliver the discharged barrel to the place of disposal. r,

During the hoisting operation. the operator stands by the machine to suitably gov ern its movements through the agency ot the control lever 29 and the brake lever 5?; As soon as the movable hoisting bar and consequently the cradle has been raised sulliciently to roll off and discharge the barrel at the desired elevation through the rear of the apparatus, the operator throws the conlos trol lever 29 to disconnect the clutch and' interrupt further upward movements of the cradle. Obviously. the hoisting bar and cradle immediately descend by gravity, the hoisting cables 21 being unwound from the drum 16. The speed of descent is under the control of the operator through the brake lever 52 as will be understood.

Of course, the apparatus is equally applicable for unloading purposes when it isdesired to lower barrels from one level to another. ln this ycase, the operation is merely reversed, as will be apparent without further description. v

The level of discharge is determined by the height of the cross bar 13 which may be made adjustable. so that barrels, bales or the like, may be unloaded at any desired height. Thus the rear sections of the A-frames may be providedwith a number of spaced holes 53 to coincide with a hole at each end of the cross bar 13 which'may be held in adjusted position by means of ,pins or bolts. The height of the guides 36 also may be made adjustable by constructing each of two members of telescoping sections.` Provision may be made on cross bar 13 for adjusting and holding the iexible hoisting members or chains 38 to theedesired length to suit the height of cross bar 13. A

The ent-ire structure 1s preferably mountedon-trucks or

wheels

40 and 40". The wheels 40- are mounted on an eccentric shaft 41 in such manner as to permit of their being raised to allow the frame to set firmly on the Hoor or lowered to make the device portable. The shaft 41 is mounted in suitable bearings on the frame and has its ends bent to provide offset or eccentric axles 56 for the

wheels

40, 40. A lever 57 for rotating the shaft 41 is secured thereto and is held 1n place when the wheels are in operative position by the lug 58. The wheel 40a is carried in a yoke 61 on the lower end of the rod 59 which is slidably mounted in thebrackets 60 and 60". A bent handle 62 having a oke member 63 is pivoted to the yoke member 61 upon the pin 64. A bearing block is loosely mounted on the rod 59 between the lower bracket 60a and the yoke member 63. The pin 64 acts as a fulcrum so that when the handle 62 is depressed the fingers of the yoke members 63 raise the bearing block 65 and the bracket 6()a so that that side of the apparatus is raised off the floor.

In order to provide against possible injury to the apparatus in the event that the operator fails to disconnect the clutch after the barrel is discharged, a safety mechanism is provided which is ada tedito automatically actuate the control ever 29 to throw j out the clutch and arrest the operation of the machine. This mechanism comprises a hooked projection 44 formed at the lower end of an extensibly adjustable rod 45 that has its upper end pivotally connected to one end of an arm 46 havingits other end pivotally mounted to thek upper front portion of the side frame 11. The arm 46f is'swingable in position about its pivoted end and its opposite end is suitably positioned by a guide frame 47 attached to side frame 10. A projecting lug 49 forms a part of the arm 46 and extends into the path of the hoisting bar 18 in such manner that as the bar approaches its upper limit of travel, it engages the lug 49 and raises the arm, which in turn elevates the hooked projection 44 of the rod 45. This projection 44 then engages and actuates the control bar 29 whereby the clutch is released to disconnect the hoisting mechanism from the source of power and thus prevent injury that might otherwise be caused.

When the apparatus is in use the electric motoris permitted tovoperate continuously and the attendant by means of the lever 29 actuates the clutch to raise thev cradle as fast as barrels are rolled on.or supplied to the hoisting cradle, using the brake lever 52 to control the lowering of the cradle.

I have found that by the use of m hoist heavy barrels can be raised steadi y and easily at the 'rate of ei ht barrels a minute for an indefinite perio Furthermore, the

apparatus is compact, self-contained and unitary 1n construction and moreover is easily portable to wherever it may be desired to be utilized. It is especially adapted for its work by reason of the fact that it is so constructed as to permit the barrels, or other loads, to be easily and quickly rolled into the machine' fromthe front and upon the hoistin 'cradle and, after beingelevated, to be rea ily and expeditiously discharged at the desired height through the rear of the machine. Apparatus of preferred form and contruction has been illustrated and described or the purpose of showing a way in which this invention may be used, but the inventive f/ thought upon whlch this application is based, is broader than this illustrative embodiment thereof, and I therefore intend no limitations otherthan those imposed by the appended claims.v .A
