WILLIAM F. BARNES, OF ROCKFORD, ILLINOIS, ASSIGNOR TO W. F. t JOHN BARNES COMPANY, OF ROCKFORD, ILLINOIS.
TOOL-CARRIAGE FOR LATHES.
SPECIFICATION forming part of Lettersu Patent No. 699,440, dated May 6, 1902.
Application tiled February 9,1901. Serial No. 46,726. (No model.)
.T0 LZZ whom it may concern:
Beit known that I, WILLIAM F. BARNES, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and -useful Improvements in Tool-Carriages for Lathes, of which the following is a specification.
The object of this invention is to move the tool-carriage of a lathe in either direction through the medium of beveled gears, the large gear provided with a concentric series of teeth into mesh with which the pinion can be moved, thereby imparting different speeds to the carriage.
In the accompanyingdrawings, Figure 1 is a plan view of the apron. Fig. 2 is an inner face view. Fig. 3 is a face representation of the pinion. Fig. 4 is an isometrical representation of a section of the large beveled gear, showing the form of -the teeth.
The apron and most of its attachments are of an old construction and shown in Letters Patent granted to me May 6, 1890, No. 427,494, and are made use of in this application for the purpose of giving a clear idea of the relation of my improvements thereto.
The screw 1 is driven from the head-stock by the usual gear connection therewith, and the toothed rack 2 is a stationary part of the lathebed and has a gear connection with the small pinion 3. On the screw 1 is located a pinion 4 and is slidable thereon and rotates vtherewith by reason of the feather 5 and the lengthwise groove 6 in the screw. A yoke 8 has a pivotal connection with a collar 7, loosely connected with the pinion 4, and the other end of the yoke has a connection with the apron 9 by means of the thumb-nut 10 and the lengthwise slot 11, provided with the end of the shaft, and by means of this thumbnut the face-plate can be held by frictional contact in connection with the pinion 3 to revolve it, or it may be revolved free of fthe pinion. The teeth 15, 16, and 17 of the face-plate are in double-Wedge form in order that the teeth of the pinion 4 may enter or come in mesh' therewith without breaking them and can enter from either end of the teeth as the pinion moves across the face-plate. By this construction of gear connection between the screw 1 and stationary rack 2 four dierent speeds may be given to the apron in either direction, and the movement of the apron is positive.
I claim as my invention-2'- In a lathe, the combination of a toothed rack and apron, a .driving-shaft, a gear connection between the shaft and rack comprising a spur-toothed pinion, and a face-plate having a series of concentric rings of teeth, the pinion made movable into mesh with the several rings of teeth and across the face of the plate and means for holding the pinion in its adjusted position, the teeth of the intermediate rings being of doublewedge form.
WILLIAM F. BARNES.
