HOISTING APPARATUS.

Specification of Letters Patent. Patented My 21 1912. Application filed August 28, 1911.

Serial No. 646,430.

.To all whom 'it may cof/wem:

Be it known that I, EUGENE BROWN, a citizen of the United States, residing at Colfax, in the county of lVhitman and State of lVashington, have invented a new and useful Hoisting Apparat-us, of which the following is a specification. v

This invention has reference to improvements in hoisting apparatus and is designed more particularly' to provide a hoist-ing apparatus which may be attached to the frame of a wagon whereby heavy articles are readily lifted into and deposited on the Wagon, the hoisting apparatus being attached to and detached from the wagon in whole or in part with the greatest facility.

The present invention is especially adapted for the handling of grain which in the far western portion of the United States is threshed out in the field and deposited on the ground in bags holding approximately two bushels each and weighing from one hundred and thirty to one hundred and forty pounds apiece. It is customary to load the bagged grain into wagons and so carry the grain to the point o f shipment instead of storing the loose grain in granarles or elevators. The lifting of such bags of grain from the ground-into the wagonusually takes the labor of two men and 1s an exhausting labor` and if attempted by one man alone is too exhausting to be kept up for any length of time. Heretofore no device has been available for the ready lifting and deposition of the bags of grain in the wagons by which the grain was transported to the shipping point. For such purpose the present invention provides a crane and a supporttherefor which may be attached tothe side of a wagon frame with t-he greatest ease and with the aid of such tools as are custolnarily found on a farm.

To keep the cost of -production of the struct-ure of the present invention, and con- 5 sequently the price at which it may be sold to those needing such devices, within reasonable limits, the structure is made ofas few parts as may be and such parts in the main as can be bought in the open market. Furthermore, the device is constructed in a manner to permit the handling of such bags of grain as have been mentioned, or like weights, by a single man or boy as expeditiously as the can be handled in the ordinary manner y two men, and the structure of the hoisting device permits its partial dismantling when the wagon is being moved over considerable distances, so that the parts are not in the way, or substantially the whole structure may be removed from the wagon when it is not desirable to transport it.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that while the showing of the drawings is of a practical form of the inven- /tion the latter is by no means limited to strict conformity with such showing of the drawings, for it is susceptible of various changes and modifications so long as the salient features of the invention are retained.

In the drawings :-Figure 1 is a perspective view of the invention as applied to a wagon. Fig. 2 is a section on the line 2 2 of Fig. 1 but drawn to a larger scale. Fig. 3 is an elevation of the upper end of the crane omitted from Fig. 2 but drawn to the same scale. Fig. 4 is a diametric section through the windlass structure in the line of the longitudinal axis thereof, some parts being shown in elevatio-n, but drawn to a larger scale'than Figs. 1, 2 and 3. Fig. 5 is a section on the line 5-5 of Fig. 4 and showing the back stop pawl in position. Fig. 6 is a section similar'to Fig. 5 but with the outer ratchet wheel broken away and showing the inner pawl in a position substantially diametric to that of Fig. 5.

Referring to the drawings, there is shown in Fig. 1 a wagon 1 which may be taken as typical of any suitable structure for the purpose, and which is designed to receive a load, such7 for instance, as bags 2 of grain, as already referred to. To a side bar 3 of the wagon on the under side thereof, considering the wagon in ordinary position, there is secured al strip 4 preferably of angle steel, and this striplis made fast to the bar 3 b screws 5 or otherwise. Approximately mi way of the length of the strip 4 the bar 3 has fast thereto a bracket 6 with a terminal portion 7 projecting in a substantially horizontal direction beyond the front face of the bar 3, the bracket 6 being made fast to the rear face of the bar 3 by screws 8 or in any other appropriate manner.k These two parts just described are the only parts ofthe whole Y struct-ure made ydirectly fast to the wagon termediate brace member 11 approximately parallel with the end members 10 but spaced therefrom, being nearer to theupper end member 10 Vthan the lower end member 10, the terms of position being-with respect to the parts when in normal Working position. The side members 9 of the frame carry angle clips or brackets 12 made fast totheframe members by bolts 13 or. in any other apl propriate manner, and each bracket 12 has an angle extension 14 parallel with but spaced from the correspondlng slde member 9,. so that the side members 9 may rest l against the outer face of a wagon side bar 3 with the angle portion 14 of the bracket 12 engaging the inner face of sald bar, there- I by holding the frame to the bar. The bolts different thicknesses.

13 may carry between the bracket 12 and thecorresponding face of the respective side member 9 washers 15 to accommodate the structure to wagons having side bars 3 of The frame made up ofthe members 9, 10 and 11 also carries a strap 16 havingapproximately right angle extensions 17 at the ends, and these extensions are riveted or bolted to the side members '9,-so that the strap 16 is opposite the brace member l1 in spaced relation thereto andon the opposite face of the frame from said brace member.- Moreover, the strap 16 lis held to the frame by braces 18 in a manner to render the strap 16 rigid with relation to the frame. l,

Near one endof the frame, such end being the one more/distant fromv the strap member 16, are latch levers 19, each lever being of the first order and having its longer arm bent into an approximate right angle,'.

whilev the shorter arm terminates'in a toe 20 projecting from said 'shorter arm of the-lever in a direction opposite from the direc-l tion of the vangle portion of the longer arm. When thel frame'is placed on the bar 3 the toe 20 may beengaged behind the dependingweb of the angle vstrip 4, the latterbeing attached t'o the bar 3 sothat one web will depend therefrom substantially flush with the outer face of the bar 3. Inthis'manner theJ frame made up of the members 9 and 10 and the 'parts carried therebyl may'be locked to the bar 3 as firmly as-necessary for the purposes of the invention by the latch levers 19 but by properly mani ulating the longer arms o f the levers the rameis readily unlatched and liftedfrom the bar 3.

However, it' isdesirableithat the rframe be positively locked against accidental displacement from shocks and ars to which the Wagon may be subjecte drawn over a field. upon which thel bags of grain are deposited. For this purpose the two levers 19 have their longer arms joined by a strip 21 and this -strip is provided with when being a longitudinal slot 22 inrsuch position as to be traversed by the end 7 of the bracket 6 when the latchlevers are in the locking position, and the-said end 7 is perforated for the passage ofa pin 23 which may be held vfast to the strip 2l by a vchain 24 or otherwise to prevent the pin .from` being lost. When the bracket end 7 is in traversing relation to the strip 21 andthe pin 23 is in place, the latch levers cannot move to the unlatchedpo'sition and the frame is therefore locked against accident-al displacement on the bar 3, but whenever it is desirable to remove the frameit is only necessary to withdraw the pin 23 and by grasping the strip 21 move both levers simultaneously to the unlatched position, whereupon the frame made up of the members 9 and 10 and other4 parts carried thereby may bel readily lifted from the bar 3.

The lower end member 10. carries about midway of' its length a step bearing 25 and the upper bar 10 about midway of its length carries a journal bearing 26, the end member 10 havingy a passage therethrough coincident withvthe bearing26 for the upright memberA of a crane 27, the lower end ofthe upright member having a' bearing in the step 25 and transversing the bearing 26.

The crane is prgvided with an angle or overhanging arm 28 at approximately right angles to the upright member, as is customary in cranes, and this arm 28 is'strengthened by an angle brace 29 made fast lat one end to a collar 30 on the u-pright member ofl the craneimmediately above the bearing 26, and at an appropriate point onl the arm 28 of the crane the brace 29 has a collar 31 made fast by a rivet 32 or otherwise. upright member lof t-he crane and the overhang member may both be made of pipe and the two parts joined together by an ordinary elbow coupling. l The brace 29 may also be made of piping.

The

. The intermediate member 11 at'one side crank '38 held lto the-shaft by a pin 39,V

which latter'ma' be a cotter pin and may be'made fast to .j e crank against accidental loss by a chainill.`

Mounted,olifthel shaft `35 is a drum 41 with end ilangest42,ji43,' respectively, the end ian s 43-being'flpf. greater diameter than the ange 42anl'formed on theJperiphery lwitha circulargseries of ratchet teeth 44 to be engaged by a-pawl 45 lpi'voted to a holder 46 in turn made fast to the adjacent side member 9 of the frame. Thedrum is hol- `low and open at one end, while the other pawl 51. Within the ,drum 41 adjacent the web 46 is an annular series of inwardly directed teeth 52 and these teeth and the pawl 51 are shaped for engagement one with the other, but the relation of the teeth to the pawl and its carrying ear 50 is such that the pawl may move away from and out of engagement with the teeth or may move into 'engagement with the teeth under circumstances to be described. Made fast to the drum for winding thereon is a rope or strand 53 of any suitable material, such as iexible wire rope and this rope is carried about a pulley 54 mounted in an angle ,bracket 55 made fast to the upright member V27 of the crane and the overhanging arm 28 thereof adjacent the connection between these two members, and from thence the rope is carried to another pulley 56 supported by a bracket 57 made fast to the outer end of the overhanging arm of the crane. The rope 53 is carried from the pulley 56 over another pulley 58 and the end ofthe rope is made fast by a ring 59 to' the bracket 57. The pulley 58 carries a pair of lifting tongs 60 which may be made `of angle metal and be appropriately shaped to grasp; a filled bag 2 without injury to the latter, or these tongs may be replaced. by other grasping means vadapted 4to the particular form of the material to be lifted. Of course, the pulley 54may be differently located so that the rope or cable will follow a different path from the Windlass to the pulley 56, as these are matters which may be varied within quite wide limits and do not affect'the general operation of the device.

The brackets or clips 12 are made adjustable lengthwise of the members 9, as well as to and from them, the lengthwise adjustment being accomplished by providing elongated slots in the clips 12 for the bolts 13, and the device is, therefore, lreadily adapted to wagons where the side bars 3 may vary in width and thickness. The crane is attached to either side of the wagon as may be desired.

Suppose, now, up sacks of grain which have been left by the harvesting machinery'on the lfield, so that such sacks of grain may be carried to the point of shipment. The wagon is driven to the appropriate point, the crane is swung outwardlyvfrom the wagon, this being permitted by the bearings 25 and 26, andl the that it is desired to `gather l tongs 60 are drawn downwardly until they may be caused to embrace a sack' of grain. The drawing down of the tongs necessitates the unwinding of the cable 53 from the drum 41 which is permitted by the lifting of the back stop pawl 45. Under ordinary circumstances when there is no'loadA on the crane the handle 38 will gravitate to the pendent position and in this condition the ear 50 with its pawl 51 is uppermost and the pawl 51 will fall until in engagement with the collar 48, such position being shown in Fig. 5. The drum is thereby disconnected from the shaft 35 and may freely rotate under the weight of the tongs or because of a slight force applied to the tongs tending to unwind the cable 53 from the drum, and there is no danger of the pawl 51 engaging the teeth 52 under such circumstances. In o'rder to lift the engaged sack, the operator grasps the crank and turns it. For a portion of a turn the crank is inactive, but as soon as the ear 50 is moved to the lower position the pawl 51 becomes pendent and drops into engagement with one of the teeth 52, and thereafter as force is applied to the crank the drum 49 participates in the rotative movement of the crank,

the pawl 51 being held against accidental escape from the teeth 52 by the applied pressure, and so long as rotative movement is applied to the crank the drum will turn and wind the cable 53 thereon and through the tackle provided will cause the lifting of the sack, which may be accomplished by a single person, even of comparatively little strength, because of the multiplying eect of the tackle. When the sack'has been raised to the desired height it will be there held by the back stop pawl 45 and the crane may be swun theubody of t e wagon, when the crank may be again rasped and by releasing the drum from the ack stop pawl 45 the sack may be gradually lowered on to the wagon. The sack is new released from the tongs and the crane may be swung to the first position, after which the tongs may be grasped and around until the sack is over l pulled to the lowered position, the crank 38 I' ing crank to possibly injure the operator and also to add its resistance to the ready.

` frictional resistance tothe rotation of the drum, so that itl will not rotate unless there be some force applied tothe tongs. This avoids any jliability of the cable 53 becoming unwound from the drum to too great an extent and therebybecomi'ng tangled.

When the load'on'the Wagon is completed, or all the sacks in a neighborhood have been gathered, the handle is readily ydisconnected from the shaft and the crane lmay be swung over the Wagon out of the Way or if it be desirable to use the crane upon other Wagons in the field While the loaded Wagon is being driven tothe point of shipment, the Whole structure is very readily removed from the Wagon by simply manipulating the latchv levers 19 to unlatched relation with the strip '4f When Athe entire crane structure may be lifted from the Wagon frame bar 3 and be applied to another Wagon to be locked there` to inthe manner already described.

While the foregoing description has beer.l

confined largely to a structure particularly v adapted for hoisting sacks of grain into Wagons, it Will be understood that by changes 'in the form of the tongs, or even Without' changes in the tongs the device may be employed for hoisting other things 4than sacks of grain into Wagons and may be utilized in other connections, but the device is designedmore particularly for the specific purpose described, and is especially adapted .for such Work, and the facility With which the device may be attached 'to or removed from Wagon frames of ordinary structure greatly enhances the value of the invention.
