SPECIFICATION forming part of Letters Patent No. 293,726, dated February 19, 1884.

` Application ledJuly2/,1883. (No model.) l v To all whom it may concern: l

Beit known that I, Rosi/TAN I. FANCHER, a citizen of the United States, residing at Baldwinsville, in the county of Onondagaand State of New York, have invented a new and useful Wooden Plug, of which the following is a specification. Y

My invention relates to an improvement in plugging holes in the panels of carriagebodies, or the holes in any and all other woodwork where they are made for the purpose of inserting screws or for any other purpose, and require to be filled again withv wood in such a manner as to present a solid and level surface; and the objects of myimprovements are, rst, to provide a perfect joint for gluing the plug into the hole; second, to make the joint at the surface of the .wood in such amanner that it willnot -be broken or disturbed by the action -of the atmosphere or moisture. I

attain these objects by the mode illustrated in theaccompanying drawings, in which- Figure l is a vertical section of the improved plug as it is placed in the wood when iinished; Fig. 2, the improved plug as it -is made ready for use; Fig. 3, a vertical section of the old plug as it is placed in 'the wood when finished; Fig. 4, the old plug as it is made -ready for use. i y

In Fig. 1, A represents a section of a'panel; B, the plug; C, the overlapping rim or lip left on the plug after it is finished level withv the surface of the panel. Regarding Fig. 2, as

j shown, the vertical side at the top is intended to show the plug as Vit is made when ready to use. After the plug is glued into the hole, the top is dressed down, so as to leave a knife-edge on the plug, as shown in Fig. l.

By the old mode of using plugs, as shown in Fig. 3, it is impossible to glue 'them in such a manner as to keep the surface perfect after exposure to the action of the atmosphere or moisture. Especially isthis the casein carriage-work, where the panels are finished with paint, the plugs always showing through the 'paint in a short time after being finished.

N ow, by making the plug with an overlapping rim or lip, as shown at C, Fig. l, and tting it into the panel, which has a countersunk hole,

as shown, I obtain a perfect glue joint between 5o the rim or lip of the plug and the panel, and

the rim of the plug, being iinished to a sharp edge at the outside, leaves the body of wood at the edge so tight at the joint `in the surface of the panel that it'is not easily disturbed by the 55 action of the atmosphere or moisture, being more firmly held by the glue than if the body f of wood were heavy at this point.4

A striking advantage in using the improved plug is in getting a joint for the glue nearly 6o iiatwise with the grain ofthe wood,in which position it is a well-known fact that glue will hold wood `together stronger than when the joint is made so as to havethe ends of the grain meet, as is the case in the joint formed by us 65 ing the old plug, -all plugs being cut so that the grain runs the same as in the panel. The lower part of the improved .plug is fitted so as to drive tightly into the hole and draw the rim or lip of the plug down, so that theglue may 7o may set firmly.

I am aware that prior to my invention plugs have been used as shown in Fig. 3; but I am not aware that they have been made or used with an overlapping rim or lip as herein de 75 scribed and shown in Fig. 1.

What I claimand desire to secure by Letters Patent of the United States, is-

A wooden plug having an overlapping bev--y eled rim or lip, in combination with a counter- 8o ROSMAN I. AFANGHER.
