HOIST.
Application filed April 8, 1926. Serial No. 100,753.
The invention generally relates tohoists and has for its object to provide a simple and economically manufactured hoist strucport framing, a lifting frame pivoted to the support framing and having provision for connection with the thing to be lifted, and a piston plunger and pressure cylinder connected to the supporting frame and the lifting frame adapted to efiect a movement of the latter frame relatively to the former to provide the hoisting action, the parts being so constructed and arranged that the hoisting action is accomplished in an efficient manner and whereby the hoist parts will not interferewith the workmen using the same but will provide ample room for them to accom lish their task unhampered.
Witli the above and other objects new that will hereinafter appear, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described, then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which: Figure 1 is a side 'elevation of the hoist, the lowered and elevated positions thereof being shown in full and dotted lines respectively.
Figure 2 is a plan view of the invention.
Figure 3 is a front end elevation of the invention.
Figure 4. is a detail perspective view of the front end of the lifting frame.
Fi e 5 is a detail perspective View of the front end of one side beam of the lifting frame, the lifting fork thereof being removed.
Figure 6 is a central vertical longitudinal section illustrating the connection of the piston plunger with the arched cross brace.
In carrying out my invention, I provide a pair of side base beams 1 and a pair of uprights 2, one being secured to project vertically from the rear end of each of the beams 1 and which are suitably braced as at 3. 'At least one cross brace beam 4 is rovided intermediately of the ends of the ase beams 1, the purpose for which will presentl appear. Y
T e parts thus far described comprise what I term the base frame of the invention and upon this frame is pivotally mounted a lifting frame, suitable extensible elements being interposed between the two frames and means provided for extending and retractin .the extensible elements to provide for a .li ing and lowering of the lifting frame in the manner later to be described.
The lifting frame is constructed to comprise a pair of side arms 5 pivoted at their rear ends as at 6 to the uprights 2 and each composed of a pair of flat bars spaced slightly apart by suitable spacers positioned at intervals and at their front ends by spacer lugs 7. The front end of each said arm 5 is equipped with an axle receiving fork rest 8, and a cross brace 9 is secured across between the beams 5 intermediately of the ends thereof and approximately in vertical alignment with the cross brace 4: of the base frame. It will be observed that the cross brace 9 is upwardly arched, the purpose for which will later be described, and is suitably braced as at 10, the rear ends of the braces being secured between the bars of the arms 5 to secure and space the same.
The front ends of the beams 5 are also joined by a cross brace and lift extension member 11, the purpose for which will later be described.
In the adaptation of the invention herein disclosed I have illustrated the extensible elements-referred to as being in the nature of a pressure cylinder equipped with a fluid actuated plunger.
For effecting the lifting and lowering of the lifting frame, in the accomplishment of the purposes for which the invention is designed, the pressure cylinder 12 is mounted upon the cross beam 4 of the base frame by having its bottom cap 13 pivotally mounted upon the cross beam as at 14. The top cap 15 of the cylinder is provided with an upwardly extending guide sleeve 16 adapted to guide the plunger 17 which projects through the said top cap and is secured to the piston l 18 reciprocable in the cylinder 12.
The upper end of the plunger 17 is ballind-socket connected as at 1-9 to the arched race 9.
By providing the arched brace the positionin of the ressure eylinder as illustrated is made possib e and the device so compacted that a minimum of space is necessary for the operation and positioning of the device, with the front ends of the liftin frame presenting the fork rests 8 thereof 1n suitable position for receiving the axle of an automobile the end of which it is desired to elerate for purposes of inspection or repair. Obviously, as the piston and plunger are forced upwardly in the cylinder by flu1d pressure admitted in a manner soon to be described, the lifting frame will be elevated, swinging on its pivotal connection at 6 and causing the fork rest equipped ends thereof to swing in a wide are for lifting the machine end or other article to be lifted. So long as pressure is held in the cylinder the frame will be held securely at its elevated position and when the'pressure is permitted to bleed out of the c linder the lifting frame will be slowly an safely lowered to its normal position.
' For admitting and exhausting fluid pressure into and out of the cylinder 12 'an inlet and exhaust pipe 20 is provided and connected in communication with the interior of the cylinder beneath the piston 18. The pipe 20 is connected with a pressure pipe line 21 through the three-way control valve 22. By adjusting the valve to one position fluid under pressure may be admitted to the cylinder to effect an elevation of the frame, when the valve may be shifted to a holding position for holding the pressure and maintaining the elevated position of the lifting frame, and when the purpose for which the frame has been lifted has been accomplished the lever may be moved to a third or pressure bleeding position to permit bleeding of the fluid out of the cylinder and the gradual return of the lifting frame to its normal lowered position.
To overcome any tendency of the frame to inadvertently lower, due to pressure leakage, I provide the plunger 17 with a plurality of sockets 33 to receive the securing pin 34 to secure the frame against such inadvertent lowering.
The member 11 hereinbefore referred to serves several purposes. It not only serves to brace the fore ends of the lifting frame side arms but also provides an extensible lift element for facilitating the liftin of an engine or other heavy unit, which tion would be less practicable of accomplishment with the fork end equipment.
The member 11 is made of U shape to include side arms 23, pivoted at 24 to the fore ends of the frame arms 5 and the cross portion 25. In this manner the member may be turned back out of the way when the forked ends are being used to allow a maximum of working space for the workmen and for the straddling of rear transmission housings when rear ends are being hoisted (see Figure 2), and extended forwardly to provide an extended central lift connection when such is desired for purposes above explained, see Figure 4.
The cross portion 25 is provided with an angled lug 26 adapted to rest on a cross brace 27 secured across between the frame arms5 just in advance of the cylinder position. 1
The lug thus provides a rest for the member 11 when positioned as shown in Figures 2 and 3 and as a mounting means for the swivel connector eye 28 to which things to be lifted may be connected, the swivel eye permitting a turning about of the lifted thing for convenience of inspection and work thereupon.
The forks 8 are made removable by equipping each thereof with a depending foot 29 adapted to be received in the recess formed in each frame arm end between the bars thereof and the lugs 7 and 31 secured therebetween.
The lugs 31 are each bent inwardly as at 32 to provide rests for the frame 11 when swung to its position illustrated in Figure 4.
By providing the peculiarly constructed lifting frame, pivotally mounting the same at one end upon the base frame and the fluid pressure actuated cylinder and plunger interposed between the frames intermediately of their ends, greater strength and a wider range of lifting action is provided than is possible by the use of ordinary plunger elevated platforms and more free room for the repair man to work in. The pivotal connections of the cylinder and the plunger with the respective frames also provide for great flexibility and the necessary relative movement of the frames.
From the foregoing description taken in connection with the accompanying drawings, it is thought that the novel details of construction, manner of use and the advantages of my invention will be readily apparent to those skilled in the art to which the invention relates.
What I claim is:
1. A hoist of the class described comprising a base frame, a lifting frame including side bars and being pivoted vto said base frame, means for elevating and lowering the lifting frame, and a U shaped frame pivoted to the free ends of and between the side bars in position for being extended beyond the ends of said bars or folded back between said bars to form a lifting frame cross extension or an open space between the side bar free ends accordingly as said U shaped frame is extended or folded back..
2. A hoist of the class described comprising a base frame, a lifting frame including side bars and being pivoted to said base frame, means for elevating and lowering the and an angled lug carried by the U shaped frame to engage the cross brace when the said U shaped frame is in the folded back position to form a rest therefor.
3. A hoist of the class described comprising a cylinder,v a base frame, a lifting frame pivoted to the base frame, a plunger head reciprocable in the cylinder, a plunger secured to the plunger head and projected through one end of the cylinder, means for introducing fluid into and exhausting the same from the cylinder to reciprocate the plun er head and plunger, ing the lower end of the cylinder to the base frame, means for effecting a pivotal connection between the projected plunger end and the lifting frame to cause the latter to be elevated and lowered with relation to the former accordingly as the plunger is reciprocated, fork rests mounted on thefree end of said lifting frame, a U shaped frame pivoted at its end in said liftin frame inwardly of the location of said ork rests, a
means for pivoting a c linder, a base frame, a lifting frame pivote to the base frame having spaced pairs of bars forming the side arms thereof, a plunger head reciprocable in the cylinder, a plunger secured to the plunger head and projected through one end of the cylinder, means for introducing fluid into and exhausting the same from the cylinder to reciprocate the plunger head and plunger, means'for pivoting the lower end of the cylinder' to the base frame, means for effecting a pivotal connection between the projected plunger end and the lifting frame to cause the latter to be elevated and lowered with relation to the former accordingly as the plunger is reciprocated, a U shaped frame mounted in the free end of the lifting frame to be movable from a retracted to a projected operable position, lugs for securing and spacing the fore ends of the arm forming bars and providing receiving pockets between certain lugs, and certain of said lugs being bent to form rests for the U shaped frame when projected, and fork rests having foot extensions removably insertible in the receiving pockets to removably mount said fork rests.
