SPECIFICATION forming part of Letters Patent No. 309,318, dated December 16, 188%.

Application filed May 26, 1884.

ger-handle, which are adjustable to varying sizes and tapers of auger-shanks, and which embody improved means for operating the same, whereby the clamps are made to grip the auger-shank with great force.

In the drawings forming part of this specification, Figure l is a plan view of the under side of an augerhandle; and Fig. 2 is a similar view thereof, showing the centrallylocated clamp-ease in section. Fig. is a side elevation, partly in sect-ion, and said three figures illustrate an auger-handle constructed according to my invention. Fig. at is a view of one of the clamps. v

In the drawings, b is the clampcase, to one end of which is fixed one of the ordinary wooden handles, a, and the other one is secured to the clamp-collar c, which screws into one end of said case b. The inner end of the clamp-collar c is made with an interior inclined clamp-seat,z. The clamp-case, as well as the collar 0 and the clamps to, are of suitable metallic construction. The case I) is provided with an annular shoulder, (1, around its interior, and has the clamp-pin c passing transversely through it, and adapted to be firmly secured thereto. The clamps 'v o are pro vided each with a shank-groove, as shown, to furnish a suitable receiving-socket for the tapering shank of the anger in, and one end of each clamp is perforated to form a pin-hole, a', through which the pin 0 passes when the clamps are in operative position in the case b, and on which the clamps have a certain degree of vibratory motion and an endwise movement,

(No model.)

and hence said pinholes are made larger than the pin 0. The ends of the clamps n adjoining the shoulder d are bevelethas also are their ends adj oiuing the inner end of the collar 6, and the lastnamed ends of the clamps are adapted to have a bearing on the abovementioned seatz in the collar when the latter is forced against them, as hereinafter set forth. By reason of the size of the hole :0, as compared. with that of the clamp-pin c, as above described, the clamps are permitted to rock on the pin to adjust themselves to anger-shanks of greater or less taper, and therefore they adapt themselves to large and small shanks. In Fig. 3 only the shank part of an anger, w, is shown.

In operating my improvements the handle a,which has the collar e secured to it, is turned to unscrew the latter to draw it away from the ends of the clamps o and let them open. The shank of the anger is then inserted between the clamps, and said collar-handle is turned, forcing collar 0 against the ends of the clamps, and thereby they are first moved against the shoulder (1, whereby their ends adjoining the latter are forced together, and simultaneously therewith the ends of the clamps in the collar are likewise forced toward each other, and, consequently, the shank of the anger is tightly secured between the clamps, and the latter adjust themselves to the taper and size of the shank. Turning collar 0 a little away from the ends of the clamps releases the augershank.

IVhat I claim as my invention is- In an auger-handle, the clamp-case b, having shoulder d therein, the clamps o 7), having their ends beveled, the pin a, passing through said case and the ends of the clamps, and the screwcollar e, adaptedto be forced against one end of the latter, combined and operating substantially as set forth.-
