Patented Aug. 17 1948 UNITED. STATES PATENT OFFICE 2,447,150 MATERIAL HANDLING APPARATUS Thomas K. Andersen, Staten Island, N. Y. Application April 4, 1946, Serial No. 659,516
This was a slow and laborious procedure, as the,
bucket and the arms are bulky, heavy and unwieldy. Moreover, when disassembling the bucket from the arms'the bolts are frequently found to have frozen or rusted in their set position. It is a slow, laborious process-to remove and replace them and especially to line up the bolt holes in the bucket and arms when replacing them.
In my present invention I have devised an improved connection by means of which the difficulties heretofore met in prior connections are entirely obviated, and the weight of the bucket and arm is utilized to assist, instead of hinder, the assembling and disassembling operations.
An object of my invention therefore is an improved form of connecting means. Another object is a quick detachable connecting means for readily assembling or disassembling a material handling bucket and its carrying arms.
Other objects and advantages, together with the novel features of the construction and. arrangement of parts comprising my invention will appear as the description of the invention progresses.
In the accompanying drawings:
Fig. 1 is a side elevation of a portion of a material handling bucket in position adjacent to the attaching end of one of its carryin arms,
and
Fig. 2 is a plan view of one side of the structure shown in Fig. 1 looking in the direction of the arrow in Fig. 1, it being understood that the portion not shown is similar to that shown.
Referring to the drawing, I designates a bucket comprising generally two side plates II spaced apart from each other and Welded or otherwise secured to a combined bottom and back plate [2. The side plates ll extend rearwardly beyond the bottom and back plate and such extension is designated I3. As viewed in Fig. 1, the rear edge M of the extension l3 lies at an angle with respect to the body of the bucket It. Secured to the rear of the bottom and back plate I2, as by welding, and spaced apart from the ex- 2 Claims. (Cl. 214145) plates [2, thus acting, not
tensions l3, and parallel thereto, are plate members I5.
Adj acent to the upper ends of the extensions] 3 and plate members l5 are transversely arranged holes in alignment with each other adapted to receive a pin I6, as shown in Fig. 2. The pins are permanentl installed and as reinforcement for the material about the pins I secure to the extension 13 and plate members l5 the reinforcingpadsl'L'. H
Adjacent the lower ends of the extension. I 3 and plate members l5, and parallel to the aligned holes adjacent the top of such members I provide aligned holes [8' adapted to receiveremovable pins l8. Also I provide reinforcing pads I! for the material of the extensions l3 adjacent the holes referred to. I
l9 designates the bucket arms (but one of which is shown) such arms being pivotalh mounted on any suitable vehicle, as a tractor, at their forward ends. On the rear end of each arm is secured a lifting plate 2%], and secured to the inner surface of the plates 20 and holding the arms is in rigid, properly spacedrelation as a unit, is a tubular cross brace 2i. At the upper rearward edge of the liftin plates 2!] is formed a hook 22 for engagement with the fixed pins H5 in the extensions l3, and to the lifting plate 20 adjacent the hook 22, plates '20 are provided with reinforcing members 23. The combined width of each lifting plate 2%! and reinforcement 23 is substantially equal to the space between the extension l3 and the plate member l5.
Adjacent the lower ends of the lifting plates as and in alignment with each other and parallel to the hooks 22 are holes'24 to receive the pins l8. Holes 24 are reinforced by reinforcing members 25 secured to the inner faces of the lifting plates.
Secured to the outer rear edges of the arms 19 are substantially triangular backing plates 26. The rear edge 27 of each plate 26 is cut on an angle to abut, when the bucket I!) is attached to the arms 19, against the edge M of the side only as a support, but as a positioning means to correctly position the holes 24 relatively to the holes l8.
The bucket It! is shown in Fig. 1 as separated from the arms I9 and parts carried thereby. To assemble the structure, the bucket I9 is preferably placed on a support, as a block of wood, the
' bucket arms are lowered and the tractor is moved to line up with the bucket, as appears in Fig. 1.
The hooks 22 are now at a lower level than the pins 16. The tractor is then backed to bring the hooks 22 and reinforcements 23 into the spaces between the extensions I 3 and plates IS. The arms [9 are then raised to bring the hooks 22 into seating engagement with the pins 16, and as the lifting movement is continued, the lower ends of the lifting plates 20 and the reinforcements 23 will move into the spaces between the extensions l 3 and plates I 5. When the edges 21 of the backing plates 26 engage with the edges Id of the extensions IS, the holes 24 of the lifting plates 20 will come into alignment with the holes I8 in the extension for the pins I8, which are then placed in position. It will be noted that the bucket pivots about pins l6 as an axis, thus enabling the bolt holes to be brought into register with each other even though the bucket and bucket arms may not have been accurately lined up with one another.
To remove the bucket, the operation is the reverse of that just described; that is, the arms I9 are lowered to place the forward end of the bucket III on a block and the pins l8 are removed to disengage the lower ends of the lifting plates 20 from the bucket [0, after which the hooks 22 are lowered from the pins 16, and the tractor moved forwardly to free the arms I9 and attached parts completely from the bucket.
Various changes in the structure illustrating my invention may be made without departing from the spirit of the invention, and I am therefore not to be limited to the exact structure shown, other than as outlined in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. Quick detachable means for connecting a bucket to its carrying arms, comprising a pair of vertically extending members at the. back end of the bucket defining a channel and a vertically extending lifting section at the back end of each bucket arm to enter said channel, said pair of members near their upper and lower edges respectively having sets of aligned holes therethrough and said lifting section near its upper edge being formed as a hook and near its lower edge having a hole therethrough, a fixed pin in the set of aligned holes near the upper edge of said pair of members to be engaged by the hook portion of said lifting section, and a removable pin to be placed through the set of aligned holes at the lower edge of said pair of members and through the hole in the lower edge of said lifting section when said three holes are registered with one another.
2. The structure of claim 1, and a backing plate secured to the outer rear side of each bucket carrying arm at such an angle as to abut the rear of the bucket for guiding the arms relative to the bucket when connecting the same into a position wherein said three holes will be registered with one another.
