Patented Aug. 11, 1953 UNITED HYDRAULICALLY OPERATED LOADING APPARATUS Daniel S. Hoover, Mansfield, Ohio Application July 22, 1949, Serial No. 106,211
1 Claim. (Cl. 214-138) The present invention relates to hydraulically operated loading apparatus and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally there is provided an hydraulically operated loading apparatus which is unitary in its character--that is to say, the apparatus consists of a framework into which a conventional tractor may be driven and, through a few simple connecting operations, be securely fastened thereto so that the apparatus becomes de facto a part of the tractor. AForwardly of the front end of the framework is a transversely extending vertically movable platform which is interconnected with the front end of the frame by means of a pair of links and eccentrically mounted atop the platform is a vertically extending mast which is movable by an hydraulically operated motor also mounted atop the platform and connected to the lower end of the mast by a pair of forwardly extending arms. A novel means is provided for the absorption of shockdue to inertia when the mast and its attendant mechanism is swung upon its axis.
It is accordingly an object of the invention to provide an apparatus of the character set forth which may be quickly and easily attached to or detached from a conventional tractor.
Another object of the invention isthe pro-j vision of an apparatus of the character set forth which is wholly operable by hydraulic means.
Another object of the invention is the provision of novel remotely controlled mechanisms for actuating the aforementioned hydraulic means.
A further object of the invention is the provision of a novel mounting for a mast forming a part of the invention and nove1 means for moving the same.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
Figure 1 is a perspective view of an apparatus including an embodiment of the present invention,
Figure 2 is a fragmentary perspective view, partly broken away, of an hydraulic turning motor and shock-absorbing mechanism, both forming a part of the invention,
Figure 3 is a fragmentary elevational view, partly in section, disclosing certain details of the invention,
Figure 4 is a sectional view taken substantially along line 4-4 of Figure 3,
Figure 5 is a sectional view taken substantially along line 5-5 of Figure 3,
Figure 6 is a sectional view taken substantially along line 6-6 of Figure 3,
Figure '7 is a plan view, partly broken away, of certain elements of a shock absorbing mechanism forming a part of the invention, and
Figure 8 is a side elevational view of Figure 7.
Referring more particularly to the drawings, there is shown therein an hydraulically operated loading apparatus having a framework into the rear end of which a conventional tractor is adapted to be driven. The frame consists of a pair of horizontal side pieces I0, to the front end of each of which is connected an upright member II. The uprights are interconnected at their upper ends with a cross bar I2 and at their lower ends by a cross bar I3. A truss I4 interconnects the upper end -of each of the uprights With the rearward ends of its associated horizontal frame member II) and each of the members I4 is interconnected with its associated member Ill with a vertically extending brace.
rod I5. A pair of trusses It interconnects the inner sides of the vertical members II.
AiXed to the outer side of one of the hori-v zontal members I0 is a bracket I9 having a forwardly extending ear 26 to which is pivotally` connected an ear 2I of an hydraulic press having a cylinder 22 which extends forwardly of the frame and has reciprocally mounted in its forward end a rod 23 to the outer end of which is pivotally connected, as indicated at 24, a pair of upper arms 25 of a bell-crank lever which is pivoted to the frame member Ill, as indicated at 26, and which is provided with a lower arm 2l the outer end of which is pivotally connected, as indicated at 28, to one side of a platform 29. A link member 3U, similar in size to the lower arm 2'I, is pivotally connected to the forward end of the frame member I0 opposite to that to which the bell-crank lever is pivoted.
Centrally mounted and extending upwardly from the platform 29 is a cylindrical bearing housing 42 through which a shaft 43 of an hydromotor 44 extends. Afxed to the shaft 43 within the housing 42 is a cylindrical bearing block 45 between which and the lower end of the casing 42 is interposed a plurality of ball bearings 46. The shaft 43 extends through the platform 29 into the hollow interior thereof Where it is keyed, as indicated at 4l, to a rectangular block 48 whose edges are spaced from the inner edges of the platform 29 and which block is held in position by a nut 49 threadably 3 mounted upon the lower end of the shaft 43 and having a washer U interposed between the block 46 and the nut 49.
Adjacent each end of the longer sides of the block 48 is a recess 5I and a compression spring 52 is mounted in each of the recesses and is adapted, in each case, to bear against the inner end thereof and against the adjacent side wall of the platform 29.
The hydromotor 44 is provided with a cylindrical casing 53 having a conventional abutment 54 affixed thereto and a pair of vanes 55 are aflixed to the shaft 43. Suitable flexible pressure lines 56 and 51 are connected with thel hydromotor by means of fittings 58 and 59, respectively.
A pair of horizontally and outwardly extending bracket arms 60 is affixed by means of bolts 6l or the like to the housing 53 and each has alnxed thereto at its outer end the lower end of. a vertically extending mast 62 which is U- shaped in cross sectinal area, and. has the legs 63: thereof extending forwardly.
It will be apparent that when the rod. 23, is. manipulated into and out of the cylinder:y 22 that` the platform 2S: will be raised and lowered and that the. stabilizer 34. will also. be raised andy lowered as well as the mast 62 and its as.- sQciated mechanisms including the boom 15, dinner stick 18 and the attached scoon- Application of uid in. lines 5.6 or 51 will cause a movement of the Qasne around the shaft 43v and consequently a rotation of the. mast 6.2. to left or right with the shaft 43 acting as e center for Such mOve.ment-v Referring new to the shock-absorbing annaratus shown. f0.1' exallnnle, in Figure 2 and. in Figures 3 .to ,'1, inclusive, it will be seen. that. when the mast. 62 and the; various mechanisms carried vthereby is; turned in.. one direction or another about the shaft 43.- to a desired.- point, that a. very considerable, inertia yis built. up 'during' such movement and it will be. understood .that without. someumeans forv absorbingv such. momentum, greatzdamage might result: to those parts ofathe. apparatus .which might otherwise be. forced ta absorb. the shock of the 4sudden cessation of movement. It will be seen that. the
block 46 iskeyed to the shaft 43 and that'A hence the same does not move duringv the; rotation of the shaft 62. Upon the stopping of such rotation by means of the valves controlling the ow of fluid through line 56 or line 51, the further movement of the mast 62 and its appurtenances due to inertia will be absorbed by the springs 52 when torque is applied to the shaft 43 and consequently to the block 48.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled'in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the. appended claim.
What is claimed is:
In an apparatus of the character described, including a frame attachable to a tractor, a hollow rectangular platform carried by said frame, an hydraulic motor having a housing and` a vertically dependent shaft, a rectangular block positioned within the platform in spaced relation thereto and affixed to; said shaft, a bearina mounted atonsadplatforxma bearing; block. affixed to. said shaitand revolubly mounted in and. supported. by said bearing'. a mast affixed to saidfhousing; and.v Compression. Springs .internosedy between the longer .s-des 0i the Vtestamenlar block.. and the. longer inner sides of said plat-A form adjacent each endthereof..
