Application September 19, A1933, Serial No. 690,135
The device forming the subject matter of this application is a mill pick, adapted to be used for dressing mill stones.
The invention aims to provide a device of the class described in which the peens or tools may be readily removed for sharpening or repair, or be renewed, upon-occasion. A further object of the invention is to provide a device of the class described in which the chisel peen or tool may be l0 positioned with respect to the handle of the tool in such a way that the operator can work conveniently on the stone.
It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.
With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawing:
Fig. 1 shows in top plan, a device constructed in accordance with the invention;
Fig. 2 is a side elevation` wherein parts are broken away;
Fig. 3 is a longitudinal section, parts remaining in elevation. i
In carrying out the invention, there is provided a head l, which may be made of any suitable metal. If desired, the head l may be grooved circumferentially, as shown at 2, to form an intermediate body 3 and end members 4. The body 3 has a transverse eye 5 in whichv one end of the handle 6 is secured, the handle 6 being of any deare supplied in their extremities with central, longitudinal bores 7, which, preferably, are cylindrical. These bores 7 are adapted to receive the cylindrical shanks 3 of detachable or renewable peens 9 and 10. Set screws 11 are threaded transversely into the end members 4 of the head 1, and project outwardly in an'opposite direction to the handle 6. The inner ends of the set screws or se curing devices l1 are adapted Vto be received, in clamping relation, in circumferential seats 12, formed in the Shanks 8 of the peens 9 and 10.
The peen 10 is pointed, as shown at 14, but the peen 9 has a chisel edge 15, disposed, preferably, at right angles to the axis of the head 1. Shoul- 55 ders 16 are formed at the places Where the peens sired length. The end members 4 of the head 1 (Cl. SOG-#42) 9 and 10,join their shanks 8, and the shoulders 16 engage the opposite ends of the head 1 to take the thrust when the tool is in use. If desired, the inner ends of the shanks 8 of the peens 9 and 10 may engage the head l at the inner ends 60 of the bores '7, as shown at 17. The construction is such that all strain is taken off the set screws or securing devices ll, when the tool is in use, and there is no chance that the set screws will be bent, so that they will be difficult to operate.
lIt is obvious that either of the peens 9 and 10 may be taken out for sharpening or repair, and that other peens may be substituted for those shown'in the drawing.
Attention is directed to the fact that the axially, the shank 8 of the peen 9 turning in the corresponding bore 7. When the desired adjustment has been acquired, the corresponding set screw 11 may be tightened up, to prevent the 75 peen from turning further. It is therefo-re possible to adjust the chisel edge 1.5 of the peen 9, with respect to the handle 6, in such a way that the tool may be used conveniently by the operf ator, due regard being had to the angle which 30 the chisel edge l5 shall take with respect to the work. The peens 9 and l0, of course, are made of a high grade of tool steel, or similar material, and are well adapted to withstand the severe use to which they are put,
Having thus describedthe invention, what is claimed is:
A mill pick comprising a head having smooth, continuous, cylindrical, longitudinal bores in its ends, a handle connected to the intermediate portion of the head and disposed at right angles to the head, peens having cylindrical shanks detachably mounted in the bores, one peen having a chisel edge, and that peen being rotatable to change lthe angle between its chisel edge and the handle, and set screws threaded into the head -and engaging the Shanks of the peens, the set screws projectingfrom the head in a direction substantially opposite to the handle, said peen and the head having cooperating parts that abut 100 in positive thrust-resisting relation, independently of the corresponding set screw and the handle, when said peen isin use', and regardless of the degree to which it may have been rotated.
