Abstract
A hand-shovel assembly consisting of a metal shovel head and a wooden handle, the head having a socket for receiving the end of the handle which is forced into the upper open end of the socket and is retained therein without the use of rivets, screws, or other fasteners. The handle end is retained in the socket by means of a set or cured adhesive which is inserted in a viscous state into the open lower socket end and, while still viscous, is forced around the inserted end of the handle by means of a plug of wood driven into the lower socket end.
Claims12
A hand implement comprising a head and an elongated handle;
- said head having a continuous socket formed thereon with an outwardly opening handle-receiving end and an opposite outwardly-opening plug-receiving end, a handle having a portion inserted into the handle-receiving end of the socket to fit tightly therein adjacent the socket outer end but to provide a space around the inserted handle portion within the socket, a plug having a portion inserted into the plug-receiving end of the socket to fit tightly therein adjacent the socket outer end but to provide a space around the inserted plug portion within the socket, said plug inserted portion and said handle inserted portion having inner extremities spaced from each other to provide a chamber therebetween which communicates with the respective spaces around the inserted portions of the plug and handle, said chamber and said spaces being filled with a body of solid bonding material which is of substantially H-form in axial cross-section that bonds to the surrounding socket and the inserted plug and handle portions to substantially integrally connect the plug and handle portions together within the socket and cause them to tightly fit within the socket.
The method of assembling a hand implement consisting of an implement head, having a continuous socket formed thereon with an outwardly-opening handle-receiving end and an opposite outwardly-opening plug-receiving end, and an elongated handle;
- which comprises;
- inserting an end portion of the elongated handle in the handle-receiving end of the socket to fit tightly therein adjacent the socket outer end but to provide a space around the inserted handle portion within the socket;
- providing a viscous bonding material within the socket through the open plug-receiving end thereof, inserting an end portion of a plug into the plug-receiving end of the socket to fit tightly therein adjacent the socket outer and but to provide a space around the inserted plug portion within the socket and simultaneously forcing the viscous bonding material into the space around the inserted handle portion and around the inserted plug portion but inserting the plug axially to a position so that its inner extremity is spaced from the inner extremity of said inserted handle portion to provide a chamber which is also filled with said viscous bonding material, and allowing the bonding material to set to substantially integrally join the plug and handle portions together within the socket and cause them to tightly fit within the socket.
