Patented May. 6, 1930 UNITED STATES PATENT OFFICE CHARLES OF DETROIT, NIICHIGAN, ASSIGNOR TO CHICAGO PNEUMATIC TOOL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY CUSHION SHOE FOR HAMMER AND TAMPER BUTTS Application filed October 4, 1928. Serial No. 310,268.
This invention relates to ramming and tamping andmore specifically to certain apparatus, such as butts, used in such operations.
A particular object of the invention is to avoid damage to moulds and forms from the use of power apparatus. Another object is to cushion the blow delivered by power operated tamping and ramming devices without im pairing the eifectiveness of the same. Another object is to provide a simple and inexpensivecushion attachment or shoe applicable to standard butts. Still further objects will be apparent from the detailed description which follows.
In order to illustrate the invention, one
concrete embodiment thereof is shown in the accompanying drawings, in which:
Fig. 1 is a side elevational View showing the shoe in place and ready for use;
Fig. 2 is a top plan view of the cushion shoe; and
Fig. 3 is a sectional view substantially on theline 3-3 of Fig. 2.
The cushion member of the present appli- H cation is adapted and intended for use with standard butts used in tamping and ramming operations. In Fig. 1, the shoe 4 is shown applied to a butt A secured upon the end of a shaft B which projects from the cylinder C of a tool, such as a pneumatic rammer or other machine, ada ted to impart reciprocatory motion to shaft The particular form of butt herein disclosed is generally frustoc'onical in shape and provided with a circular, fiat working face a which is intended for direct contact with the work. The butt is ordinarily of metal, the weight of which may be lightened by leaving the interior hollow additional lightness may be secured by making it of aluminum or from aluminum alloy.
To protect the moulds and forms from injury, the cushion shoe 4 is arranged to enclose the lower portion of the butt A. Shoe 4 may be of any suitablematerial and is arranged to provide a thick cushion portion or face 5 for the working face a of the butt. Projecting substantially transversely. from the peripheral part of the upper face of portion 5 is a wall 6 annular in shape and tapering inwardly whereby shoe 4 appears as a hollow member with a socket or recess 7 cdnforming substantially to and arranged to fit the exterior of butt A. By preference the wall 6 is of suitable elastic material so that it may be distorted to enlarge the restrictedopening to recess 7 to permit the insertion therethrough of the large end of butt A, the wall 6 then yieldingly gripping the wall of the frustoconical portion of the butt and retaining the shoe on the butt by the resiliency of wall 6. In the present instance the lower portion of recess 7 is substantially cylindrical, as indicated at 7, and tapers inwardly thereabove in parallelism with the exterior face of wall 6, as indicated at 7" (Figs. 1 and 3). By
preference the shoe 4 is moulded or formed thereon of rigid material having a working I face, and means applicable to said butt for cushioning the blow of the latter thereby to prevent damage to moulds and forms.
2. In tamping and ramming apparatus, in combination, a reciprocable shaft, a butt thereon of rigid material having a working face, and means for applying a resilient cushion to the working face of said butt.
3. In tamping and ramming apparatus, in combination, a reciprocable shaft, a butt thereon of rigidmaterial having a working face, and a cushion member enclosing the entire lowerportion of said butt.
4. In tamping and ramming apparatus, in combination, a reciprocable shaft, a butt thereon of rigid material having a working face, and a cushion member enclosin the entire lower portion of said butt, sai member having an elasticportion for gripping the butt to hold the member in place.
5. In tamping and rammingapparatus the combination with a butt having a working. face and a tapered portion thereabove, of a hollow cushion member arranged to receive and enclose the lower portion of said butt and having a restricted portion capable of being distorted to pass over said face and of yield-. ingly gripping the tapered portion of the butt. 1
6.' In tamping and ramming apparatus the combination with abutt having an annular. working face and a frustocom'cal portion thereabove, of a cushion member of elastic material and of similar shape providing therewithin an. opening to fit the lower poition of said butt, said member being distorted when applied to said butt and retaining itself thereon by its own resiliency.
, 7; A cushion shoe for a rammer or tamper butt of substantially frustoconical form comprising a member shaped to fit over the exterior of the butt and having a tapered upper portion of elastic material providing airestricted opening, said portion being distortable to permit the insertion of the large end of the butt through said opening and t i ing the member on the butt by its own resiliency.
8. A cushion'shoefor a rammer or tamper butt of substantially frustoconicalform comprising a member formed integrally of elastic material providing a flat face and a hollow frustoconical portion extending therefrom and applicable ,to and removable from the butt by distortion of said hollow portion.
".3 9. A rubber shoe for covering the lower portion of a butt of substantially conical form above its working face comprising a hollow member moulded in one piece with a thick circular portion to cover the working 3 face of the butt and an annular inwardly tapered wall extending from one face of said portion, said wall and portion forming a recess to receive said lower portion of said butt, which recess is substantially cylindrical adj acent said circular portion and is frustoconical thereabove. y
