ARTHUR H. SKAER, 01 DENVER, COLORADO, ASSIGNOR,'BY MESNE ASSIGNMENTS, TO THE GARDNER-DENVER COMPANY, OF QUINCY, ILLINOIS, A CORPORATION OF DEL AWARE.
' DRILL-STEEL RETAINER.
Application filed August 5, 1926.
The present invention has for its object the provision of a simple and effective means carried by a rotatable chuck for retaining a drill steel in the chuck, said means by reason of its rotation with the chuck being thus relieved from a material amount of wear.
In the accompanying drawings Figure 1 is a side elevation of an embodiment of the invention with the retainer in its operative position,
Figure 2 is an end view thereof,-
Figure 3 is a longitudinal sectional view of the structure of Figures 1 and 2, but showing the retainer in its inoperative position,
Figure 4 is an end elevation of the mechanism as shown in Figure 3.
As shown, the drilling motor is designated 26. and the chuck 27. his chuck is rotatable in the barrel or cylinder of the motor by any suitable means. For example, the piston 26 may have a rifle connection 26 with the chuck, so that the two will rotate, the piston in turn being rotated by any means well known in this art. The chuck, as shown, projects from the motor 26, and has an annular groove 28 in its projecting portion. In this groove 28 is rotatably engaged a collar 29 having a pivot and tie bolt 30, on which is pivotally mounted a link 31. The link 31 is engaged with the larger end of a retaining link or loop 32, which consists of angularly disposed portions 33 and 34. The
portion 33 has its internal space 35 sufli-' ciently large to permit the passage therethrough not only of the drill steel, as 36, but also of the usual collar 37 of said drill steel. The portion 34 of the retaining link has the space 35 therein of sufficient area to permit the passage of the steel 36, but is too small to permit the passage of the collar 37, which will thus abut against said portion 34.
lVith this arrangement, it will be evident that it the drill is held in vertical position, the smaller portion 34 will ordinarily hang down in the position illustrated in Figures 1 and 2, but the link can be moved to the po sition shown in Figures 3 and 4, so as to permitthe introduction and removal of the Serial No. 127,409.
steel. When in the position illustrated in Figures 1 and 2, the steel is permitted to have a certain amount of longitudinal movement, but it cannot become detached from the chuck 27, as the collar 37 will strike against the portion 34 of the link. Inasmuch as in the structure shown, the chuck and steel are caused to rotate together, the mounting of the collar 29 on the chuck will insure that it, and consequently the steel retainer, will ro tate with the chuck, so that there will not be material wear between the parts.
From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be under stood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
What I claim, is:
1. The combination with a drilling motor and a steel holding chuck rotatably mounted therein, of a steel retainer rotatably mounted on the chuck.
2. The combination with a drilling motor, of a steel holding chuck rotatably mounted therein and having a portion projecting therefrom, and a steel retainer movably mounted on the projecting portion ofthe chuck.
3. The combination with a drill operating motor,of a steel holding chuck rotatably mounted therein and having a portion projecting therefrom, a collar rotatably mounted on the projecting end of the chuck, a steel retaining loop having its internal space sufliciently large to permit the passage of a drill steel therethrough, a portion of such space bemg less than the diameter of the drill steel collar and a portion greater than said collar, and a link connection between the loop and the collar that is mounted on the chuck.
In testimony whereof, I aflix my signature.
ARTHUR H. SKAER.
