UNITED STATES PATENT OFFICE.
LATHE-TOOL.
Specification of Letters Patent.
Patented Oct. 8, 1907.
Application filed May 19,1906- $erial No. 317,835.
To all whom it may concern:
Be it known that I, WILLIAM COLLINS, a citizen of the United States, residing at West Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Lathe- Tools, of which the following is a specification.
My invention has relation to improvements in lathe tools, and it consists in the construction and arrange ment oi parts as will be hereinafter described and particularly pointed out in the claim.
In the accompanying drawings, Figure 1 is a partly sectional elevation of a lathe tool embodying the present invention Fig. 2 is a plan view of the same. Fig. 3 is a sectional elevation taken at right angles to Fig. 1. Fig. 4 is a detail perspective view of the gib.
Referring to the drawings, 1 designates the holder of the tool, and 2, the tool post by means of which the holder 1 is secured to the carriage of a lathe. The projecting end of the holder 1 is shaped into a circular table 3 upon which is eccentrically mounted a turn-table orbase 4 which is provided in its lower side with a threaded socket 5 in which is received the reduced threaded portion of a pivot screw 6 which passes upward through a bearing opening in the table 3 and is provided with a head 7 at its lower end which bears against the under side of the table, as clearly shown in Fig. 1.
The base 4 is provided with an upstanding dovetail projection or guide 8 which is received in a corresponding recess 9 in the lower face of a slide or hit carrier 10, as clearly shown in Fig. 3, while a gib or wear plate 11 is inserted between the abutting faces of the guide 8 and the slide 10 and held in place by means of one or more set screws 12 to take up wear between said sliding parts.
The slide or carrier 10 is provided with an upstanding portion 13 through which is formed an opening for the reception of the cutting bit 14, said bit being firmly held in place by means of a binding screw 15 passing through'the top of the carrier or slide 10 and binding at its lower extremity against the top of the bit 14.
The carrier or slide 10 is adjusted back and forth by means of an adjusting or feed screw 16 which has a threaded engagement with said slide or carrier and is provided with a flange 17 which works in a notch in an ofistanding bracket or lug 18 connected to the base 4, as best illustrated in Figs. 1 and 3. By turning the screw 16, the carrier or slide 10 is fed back and forth on the base 4 to properly position the point of the cutting bit relatively to the work. The means for turning the base or turn-table embodies a handle 19 provided with a square socket to be received over the squared projecting end 20 of a screw inserted in the top of the slide or carrier, as shown in Figs. 1 and 2.
By means of the construction above described, the slide or carrier, together with the cutting bit held thereby, may be adjusted back and forth upon the turn-table or base 4 and said turn-table may also be swung on the pivot screw 6 as a center by means of the handle 19. Provision is thus made for an exact adjustment of the point of the cutting bit, thus insuring accurate turning and cutting of the tool as a whole.
I claim:
In a lathe tool, the combination with a holder adapted to be secured to a lathe carriage, of a base rotatably mounted thereon, a pivot screw passing through the holder and having a head engaging the under side thereof and screw threaded into the under side of the base, means whereby a cutting bit may be mounted on the base, and means whereby a handle may be secured so as to enable the base with the cutting bit thereon to be rotated during the operation of turning, substantially as specified.
In testimony whereof, I aflix my signature in presence of two witnesses.
WILLIAM COLLINS.
