To all whom it may concern 01 l/Vashingto-n, have invented certain new and useful Improvementsin Work-Holders for Lathes, of which the following is a speci fication.
This invention relates to attachments for lathes; and its object is the provision of an improved work-holder or attachment for a lathe wherewith various operations such as facing and boring may be accomplished upon a lathe.
The invention consists in a novel construction of work-holder adapted to be rigidly secured to the lathe slide-rest, as will be hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a perspective view of an embodiment of my invention applied to the slide rest of a lathe. Figs. 2 and 3 are perspective views of the work holder shown detached, a piece of work being illustrated as attached to the holder in Fig, 2.
The reference numeral 5 designates a portion of a blade bed, and 6 is a slide rest mounted thereon and having a slot 7 for the accommodation of a tool post, when required.
8 represents thehandle for the cross feed screw whereby said slide rest is adjustably moved transversely of the lathe.
All of the above mentioned parts are of ordinary or standard construction.
According to the present invention, I provide a plate 9 formed with a horizontal ele ment 10 and a vertical element 11 extending downwardly from one end thereof. Provided in the plate element'lO is a plurality of apertures 12 distributed throughout the same, and in the element 11 is provided a substantially vertical slot 13, as shown in the views.
141 represents a stirrup-plate provided near its upper end with a hole 15 and adjacent to its lower end is a slot 16. The stirrup plate serves as a clamping member to hold a piece of work as A, Figs. 1 and 2, against the face of the main plate 9 by means of securing bolts 17 and 18. The former, 17, passes through the hole 15 of the stirrup plate and one of the apertures 12 of the main plate and receives a nut 19 upon the threaded end of the bolt. The other bolt, 18, extends through theatre is and 16 of the two plates and also"thioi1'g'li the slot 17 of the slide-rest. 3, t
The ten 18 is Screw alt-erase to receive nuts 20 and 21 at opposite sides of the slide rest for securing the plate- 9 firmly toth latter-{and another nut, 22, is screwed upon this belt and agalnst the stirrup plate to cooperate with the nut 19 for securing the stirrup plate in position to clamp the work between the two plates. A washer plate 18 is desirably interposed between thenut 20 and the slide rest to afl ord a better bearing for said nut.
A supplementary stirrup plate, like that above described and indicated by broken lines 23 in Fig. 2, may be utilized to secure work to the plate 9 through the agency of bolts 25 extending through the plate 28 and suitably disposed apertures in plate 9. Or,
where the nature of the work will permit, a bolt, as 24, may serve to cooperate with the first described stirrup-plate for securing work to the plate 9.
The operation of the invention may be explained as follows: Assuming the eye A of a connecting rod A is to be bored with a boring or cutting tool carried by the spindle which is journaled in the head stock of a lathe, not illustrated. The plate 9 is first rigidly connected to the slide rest by the bolt 18 and nuts 20 and 21. The work, as red A in the example, is then clamped to the plate 9 through the instrumentality of the stirrup plate, or plates. The work is then adjusted to present the eye A in axial alinement with the axis of the boring tool, as indicated by broken line a; m in Fig. 1. Such adjustment is accomplished by manipulating the handle 8 to regulate the transverse position of the slide-rest 6 and then raising or lowering the plate 9 after slacking the nuts 21 and 22 to permit the relative 1novement of the bolt 18 in the slots 13 and 16 oi the respective plates.
The invention is extremely simple and affords convenient means for performing numerous operations in a lathe which have hitherto been generally done on boring machines, shapers, planes, etc.
i/Vhat I claim, is
1. The combination with the slide rest of a lathe, ota work-holder comprising a plate provided with a plurality of apertures, a stirrup plate, and bolts extending through both of said plates for clamping work there between, one of said bolts also serving for rigidly securing the Work holder to the slide rest of the lathe.
2. The combination With the slide rest of a lathe; of a Work holder comprising an apertured plate, a second plate, a nutted bolt extending through said slide rest and both of the plates, whereby the Work holder is rigidly secured to said slide rest, and a bolt acting supplementary to the aforesaid bolt whereby Work may be clamped between said plates.
3. The combination With the slotted sliderest of a lathe, of a Work holder comprising an L-shaped plate having a slot in one of the limbs thereof, a bolt extending through the slots of the slide rest and said plate for adjustably securing the latter to said sliderest, and means for clamping Work to the plate.
Signed at Seattle, Wash, this 16th day of November, 1912.
