3 Claims. (Cl. 2MP-1391) This invention relates to portable hoists 'and is `particularly adapted to be used in connectionv withV the handling of excavated dirt, markers and theA like in cemeteries.
The primary object of the invention is to mount a hoist upon wheels adapted `to handle burial vaults and thev like by straddl-ing grave openings.
Another object of the invention is to providea hoist mounted on wheelsl that can-be moved about by hand or trailedl lbehind tractors or vehicles. Y
Another object of'theinventfion isto 'provide a movable hoist adapted to support a boxffl-ikeV container used in the transferring of dirt re- `moved from graves to-a upoint Iadjacent Athegra-ve. A further object of the invention is 13o-providemeans for dumping ythe container and itsv contents into the grave after the vault has 'beenlowered by the said' hoist.
A still further objeotofv` the i'vention is the provision of means within the hoist for increasingV its lifting power while under heavy load and increasing its speed of operation under light loads.
.And a.stifllturtherlobjectnof theinventionis to provide a hand brake control. mechanism. foru controlling the Yhoist when being moved by hand from place to place.
These and other incidental objects will be apparent in the drawings, specica'tion and claims.
Referring tothe drawings: ,A Figure l isa'sideview of our-new and improve portablel hoist. y

Figure 8 is an end sectional view, taken on line 8 8 of Figure 2.
Figure 9 is an enlarged detail sectional view, taken on line 9 9 of Figure 5.
Referring more specifically to the drawings:
Our 'new and improved `portable* hoist consists of aliorizontal U-shaped frameA I;,consist'ingV 0f the tubular sidev membersz terminating 'in the" cross channelV member 3y by anysuitable'moan's, as for4 instance wel-ding. ExtendingJ upwardly from the sidek frames 2 are apairof pedestalsil. These pedestals may be wel-ded to the-side frames 2 at 5' having recnforcing gussets 6- associated.-V
therewth; Running' from the forward@ end ad jacent 'the cross channel l and approximately at a forty-five degree angle are bracing frames 1 connecting the upper ends of thepedestals' `#with the side frames `2, best illustrated` in Figure 1;
The U-shapedirame-i is mounted upon wheels 8 by stub axles 9; and having its forward end mounted -upon theV casterw'heels l0. Stub shafts Ii are xedly secured to thel crossl channelY S'by` The sleeves I2 are ro-V welding or other means. tatably mounted to theV said stub shafts-and form apart of 'theupper bearing I3-ofvthe caster-whee1 assembly. This upper bearing is secured toV ther goose neck |4- o the* caster wheel' assemblies by the king bolt F5, operating `on the ball bear-- ings I6.
A locking pin Il passes through the sleeve l2 and the stub shafts-I I, best illustrated in Figures 3 and 4, holding'thecaster wheels either down `as illustrated inv Figure 1 when the Asame is beingk operated by hand, or `in the broken line position when the same is being towed by a tractor orv vehicle; Handle bars It are rotatably mounted within thesockets I9, forming part of 'the' channel beam 3, referring to Figure 9, and' locked in place by the set screw 20 operating withinthe annularigrooves 2| of the handle bars. 'These handlebars can bemoved around tothe Vbroken line position as indicated in Figure 5 while the hoist is being towed by a vehicle.
Mechanical brake drum assemblies 22 are associated with the wheels 8. These brakes are controlled by the cables 23 trained about the idler pulleys 2d Within and underneath the cross channel 3. The ends of these cables connect to the pivotally mounted lever 25, which in turn is operated by the cable 26 running up through the handle bars, as best indicated in Figure 9 to the hand lever 2, which is held in any desired position by the quadrant 28, referring to Figure 1. The brake can be set regardless of the position of the handle bars I8.
The hoist mechanism proper is housed in the horizontal housing 29, referring to Figures 6, 7 and 8. This hoist mechanism consists of a drum 30, which is journalled to the cross shaft 3|, which in turn is mounted within the housing 29 the event that the load supported by the cable 39 is relatively light, the crank 31 is applied to the countershaft 42 which rotates the large gear 43, which in turn revolves the shaft 36 through the small gear 44 at a relatively high rate of speed. This saves time, and is Van important feature relative to our hoist. Due to the fact that a worm wheel and a worm is used the hoist is self-locking requiring no additional braking.
Referring to Figures 1 and 2 particularly, we show a container 44 in the form of a box. This box is supported through the U-shaped strap 46 into which the hooks 41 of the cross beam 4l are hooked. This is only one illustration of how the hoist can be applied to the load supported.
In the case of raising or lowering vaults, chains are usually looped around from each end coming together midway the length of the vault, a hook associated with thecable 39 is hooked into the same. Again we do not Wish to be limited to the exact use to which our hoist is adapted to be used for.
In'the operation of our new and improved hoist in the removing of dirt from a grave, the hoist and the container 45 i5 wheeled up adjacent the grave and the dirt shoveled therein, after which the hoist and load of dirt is pulled back a suilcient distance from the grave to clear the burial operations. The hoist is removed from the container, which is then covered over by a, cover, the hoist then being applied to the vault for lowering thesame, the wheels being far enough apart to straddle the grave while rolling the vault thereover. These operations are usually done by hand through the use of the handle bars I8.
If a vault or load is to be removed to any great distance, we have supplied a trailer hitch 48 for connecting to a tractor or vehicle.
Afterthe burial operation has been completed tl'ie'dirt container box 45 is then picked up by the hoist and brought to the edge of the grave, V
the end 49 of the container 45 is raised, dumping the dirt into the grave, the braking system of the hoist securely holding the hoist in the desired location.
Our hoist is admirably adapted for the transferring of marker stones and the like while yplacing the said stones. Our new and improved hoist would be equally well adapted in garagework, removing motors from vehicles or the like transferring the same to other parts of the shop.
Although certain specific embodiments of the invention have been shown and described, it is obvious that many modifications thereof are possible. The invention, therefore, is not to be restricted except in so far as is necessitated by the prior art and by the spirit of the appended claims.
.What We claim is:
l. A portable hoist comprising a U-shaped frame open at its rear end and including parallel spaced apart side bars connected at their front ends by a channel bar, vertical standards extending upwardly from the rear free ends of the side bars, a housing supported on the vertical standards, inclined braces connecting the upper ends of the standards and the forward end of the side bars, wheels mounted on the rear free ends of the spaced apart parallel side bars, stub shafts extending from the ends of the channel bar, front wheels mounted on the stub shafts, means for holding the front wheels in raised or lowered position, hoisting mechanism in the housing, includingra drum and a cable, a U- shaped support to hold a container between the spaced apart side bars, a bar at the end of the cable, and hooks at the ends of the bar to engage the free ends of the U-shaped support.
2. A portable hoist as defined in claim 1, where-V in the vertical standards are located in advance of the rear wheels, whereby When a container is held in the support the rear of said container extends beyond the rear ends of the spaced apart side bars.
3. A portable hoist as dened in claim 1, wherein the ends of the channel bar extend beyond the side bars and the stub shafts are fastened to the underside of the channel bar.
