Description

U ITE STATES Patented February 23, 190 3.
PATENT OFFICE.
JOSEPH GU ZOWSKI, OF CHICAGO, ILLINOIS, ASSIGNOR OF TVVO-THIRDS TO FRANCIS P. KUJAWSKI AND JOHN MATZ, OF CHICAGO, ILLINOIS.
DOWEL.
SPECIFICATION forming part of Letters Patent N0. 752,669, dated February 23, 1904.
Application filed July 25, 1902. Renewed December 4, 1903. Serial No. 183,829. (No model.)
To all whom it may concern:
Be it known thatI, JOSEPH GUzowsKI, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dowels, of which the following is a full, clear, and exact specification.
My invention relates more particularly to dowels for use in the manufacture of furniture and all other purposes where it is desired to secure two wooden portions together; and it has for its primary object to'provide means whereby the air and superfluous glue may escape from the dowel-socket as the dowel is driven therein, and at the same time the glue will be distributed throughout the surface of the dowel in the form of threads or small bodies remaining between the surface of the dowel and the wall of the socket.
With these ends in View my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.
In said drawings, Figure lis a side elevation of one form of the improved dowel, showing it partially driven home in the sockets in two members which are to be secured together thereby, the said members being in section. Fig. 2 is a detail side elevation of the dowel on a larger scale. Figs. 3 and 4: are side elevations of other or modified forms of dowels embodying my invention; and Fig. 5 is an enlarged longitudinal sectional view of a dowel like the form shown in Fig. 3 partially driven home in its socket, showing the manner in which the glue fills the spiral.
In the form of the invention shown in Fig. 1 the dowel proper, which is indicated at 5, is provided with longitudinal grooves'6, which extend from end to end and are preferably parallel with one another, and it is also provided with spiral grooves 7, which begin at one end and wind therearound to the other end, the spirals being crossed by the straight grooves 6. By this means it will be seen that the surface of the dowel will be provided with cross-bars of glue after it has been driven into its socket, and these cross-bars upon hardening cause the dowel to adhere with great firmness in the socket. The grooves also increase the area of the dowel and allow the wood of the socket-wall to more or less swell thereinto, and thereby produce a firmer grip on the dowel than would be possible with a dowel having a plain surface.
In Fig. 5 of the drawings this thread of glue is shown at 8, and it will be seen that it is in the form of a spiral like a screw-thread winding around the dowel and forming a body of glue of material thickness between the dowel and the wall of the socket.
In Fig. 3 a dowel is shown with a spiral thread or groove 7 only, which when driven into the socket will produce the effect shown in Fig. 5.
In the form shown in Fig. ithe spiral groove 7 is intersected at short intervals by short longitudinal grooves 9, which, however, are not continuous like the longitudinal grooves in Fig. 2, and consequently the grooves 9 serve merely as chambers or recesses for receiving portions of the glue that rise in the spiral grooves 7 and holding these portions or bodies in immediate contact with the wall of the socket after the dowel has been driven home.
Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
1. As a new and useful article of mariufac: ture adowel provided with a spiral groove, extending from end to end thereof substantially as set forth.
2. As a new and useful article of manufacture a dowel provided with a spiral groove extending from end to end thereof and longitu- JOSEPH GU'ZOIVSKI.
