ful Improvements in Portable Hoisting-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the am nexed drawings, making a part of this specificatiomand to the letters of reference marked thereon.
The present invention has for its object to provide a portable hoisting-machine or apparatus that will be simple in construction and effective in operation in loading barrels and other objects onto wagon and other platforms, also in transferring them from,,high elevations to the machine and transferring them from one. place to another, as circumstances may require.
The invention consists in a machine or apparatus constructed substantially as shown in the drawings and hereinafter described and claimed. 1
Figure l of the drawings is a perspective view of the machine or apparatus constructed in accordancewith my invention; Fig. 2, a side elevation showing the pivoted orhinged carrying-frame in an elevated position in dotted lines; Fig. 3, aside elevation of the machine or apparatus, showing it raised and in position to take the load on or transfer it to the platform of a wagon or other high elevation, also showing'a modification of the hoisting-gear ing; Fig. 4, a sectional elevation taken 'on line 0c 06 of Fig. 3; Fig. 5, an inner sideview of the hoisting-wheel.
In the accompanying drawings, A represents the stationary frame, of any suitable con struction, to the inner side of which is located the carrying-frame B ,which may also be of any desirable construction. 3 This carrying-frame is suitably pivoted to the frame A at one end by means of the shaftct, the projecting ends of said shaft, having truck-rollers b, whereby said machine or apparatus may be conveniently moved when desired. The free ends of the frames A B have concaved depressions c to form rests for the barrel or other like object to be hoisted and transferred to the wagon-platform or other high elevation. The carrying-frame B has suitable supports 61, against which rests the barrel or other like object when being elevated, and the two arms 5 5 which constitute saidfframe have connected to them a transverse brace e. The stationary frame A is also provided with a transverse brace f,which connects the sides of the frame,
these braces in both the frames strengthening 6o them at their free ends.
The form of hoisting-pulleys 0 shown in Figs. 1 and 2 of the drawings are provided with ropes g, which have their respective ends connected to said pulleys and to the transverse brace e. In Figs. 4 and 5 is shown a modification of the hoisting-pulleys, as indicated at C, in which case it is preferred to use sprocket-chains h, connected to a projection 2' and to the transverse brace e. In either case a flexible connection is provided between the hoisting-pulleys and the carrying-frame. The hoisting-pulley O has a spiral grooved guide D upon its outer edge to receive the rope g when winding same thereon. This pulley G is unlike the pulleys; fusees, and other like hoisting devices employed for elevating the movable carrier in that it is in the form of an involute cam, whereby its effectiveness and simplicity are materially enhanced, as it perfectly equalizes the pull on the crank-handle, it moving fasterjas the load is raised and is brought over the fulcrum, thereby giving an equalization ofpower and rendering the elevation'of the load much easier.
In Figs. 1 and 2 of the drawingsI have shown a simple gear-Wheel F upon the same shaft 70 that carries the two involute campulleys O. A pinion G upon the transverse o shaftl engages the gear-wheel F, and a driving-pinion II upon the transverse shaft m meshes with the teeth of the pinion G, the shaft Z having a suitableratchet n,with which engages a pivoted pawl o, as shown in dotted 5- lines of Fig. 2 of the drawings. A suitable crank-handle I connects with the projecting end of the shaft m, by which said shaft is turned. Turning the shaft on will impart motion to the involute cam-pulleys 0 through the medium of the pinions G H, and by means of the wire-rope connections with the carrying-frame the same will be elevated with its load.
In place of the involute cam-pulley O, I have shown in Figs. 3, 4, and 5 of the drawings a modification thereof, as indicated at O, the pulley in the present instance having an internally-toothed gearJ, with which the pinion K engages, and upon the face of the pulley is a spiral guide E, upon which the sprocket-chain h is wound. These pinions K are mounted upon short shafts p, to which a crank-handle may be attached. The shaft in the present instance is provided with the ratchet q, with which engages the pawl r, and a brake-band Lextends around the outer periphery of the internally-toothed gear J. One end of this brake-band is attached in any suitable manner to a bracket N and its opposite end connected to a treadle M, whereby the motion of the carrying-pulley C may be controlled. As above described, this brakeband is applied to the driving-gear when the internally-toothed gear is used, and when the gear-wheel F and its pinions are employed, as shown in Fig. 1 of thedrawings, the brakeband extends over a grooved head 0 and is in the form of a rod P, said rod being suitably attached to a bracket and the treadle at its opposite ends.
Any suitable form of brake device may be substituted for that shown, and the pawl 0 (shown in dotted lines of Fig. 1) may have a suitable handle or other means, as shown at s, for convenientlylifting the pawl out of engagement with the ratchet when desired. A brace-rod 25 connects the sides of the frame A at its upper end, and, if desired, suitable skids Q may be employed to hook over the brace-rod and adapted to be removed therefrom when not required for use, one of said skids being shown in Fig. 1 of the drawings. Suitable hanger-arms R, which are loosely or pivotally connected to the brace-rodt at or near its ends, serve also as skids, but are especially designed to support the frame of the machine or apparatus at the necessary elevation in loading or unloading, thereby adapting the machine or apparatus to platforms of unusually high elevations. The hanger-arms B have suitable spurs or hooks a at their ends to engage the platform, as shown in Fig. 3 of the drawings, and are provided with notch ed supporting-arms S. These supporting-arms are pivotally connected to the hanger-arms and are adjustable in that they are capable of engaging any one of the series of notches with the transverse rod 01, thereby supporting the hanger-arms at any desired angle found necessary.
The machine or apparatus is provided with suitable legs Tfor the purpose of supporting the frame of the machine or apparatus at an angle when the hanger-arms are not brought into use. These legs are loosely or pivotally connected to the transverse shaft a, so that theymay be held up out of the way when not required for use. To hold'the legs up when not in use, there are provided pins 10, which extend through a hole in the frame and are attached to the frame A by suitable cords or chains 11 When it is desired to use the legs in supporting the machine or apparatus at an angle, the pins are withdrawn and the legs will drop down into position.
The stationary frame and the pivoted or carrying frame and the various connections of the machine or apparatus may be constructed of any suitable material, any suit= able driving-gear for operating the hoistingwheels may be employed, and any desirable form of brake may be substituted for that shown, these several features of the invention being subject to change or modification Without departing from the principle of my invention.
