Applicatiomflled November 1o,"'191 1. Serial no. 659,488. I 1

To all whom it may concern:

Be it known that I, ARTHUR E. BEAN, a citizen of the United States, residing at Greenville, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Tool- Posts, of which the following is a specification.

This invention relates to multi le tool posts for lathes, and has for its 0 ject to provide such a post which is simple, .durable, substantial and inexpensive in construction, and efiicient and convenient in use. A further object is to provide a post of this character which can be readily engaged to the carriage of the" ordinary lathe having a T*slot therein.

To the above ends this invention resides in a novel construction and combination of parts as'hereinafter described and claimed, reference being bad w the accompanying drawing, wherein,

Figure 1 is a perspective view of the tool post as constructed in accordance with the present invention showing the tools applied thereto. Fig. 2 is a side elevation of the tool post, parts broken away.

Referring specifically to the drawing, wherein similar reference characters indicate similar parts, the tool post embodies in its essentials a body for holding the tools and a slide for engaging in the T-slot of a lathe carriage. The body comprises a square block or cube of suitable metal which by forging or other operation is made to form upper and lower portions 3 and 7, respectively, and a contract-ed circular portion 1" connecting same; Set screws 2 are passed through the corners of the portion 3 to engage the intermediate portions of the tools as is clearlyillustrated in Fig. 1, the tools resting on the portibn 7, and set screws 19 are'passed through the said portions 3 intermediate the set'screws 2 to engage the" inner ends of the tools. and thereby firmly. hold, the tools in position and also permitting the tools to be adjusted and removed.-

The slide comprises an elongated block 8 of suitable metal of T-shaped cross section to fit intothe Tslot of a lathe carriage. A bolt 4 passes through the slide and has a lower head 14 embedded in the'bottom of the slide to prevent the bolt from being drawn upward. This bolt 4 is upstanding from the slide andpasses centrally through the body to permit the body to rotate thereon. On the upper end of the bolt 4 is screw threaded a nut 5 having a handle 6. and a washer 18 is interposed between the nut and the body. Thus upon the slide being en- 1 atentedApr.8,1913.

gaged to a lathe carriage the nut 5 may be tightenedto clamp the body againstthecarriage. The slidefis provided with a longitudinal channel 16 in one end thereof extending to the bolt 4 and which is shallower in depth at'its inner end. A'socket 15 is "arranged at the outer end of the said. channel 16. A lever 9 fits in the channel 16 and projects therefrom andhas an aperture 20 in its inner end and an upper segmental catch 10-adapted to engage in the radial concaved recesses 11 provided in the bottom ofthe body. aperture 20' and engages in the slide at the inner end of the channel to pivot the lever in the channel and acoiled spring '13 is.

seated in the socket 15 to yieldingly .press the lever upward. The catchlO fits snugly A screw 12 is passed through the Q in the channel 16 and in engaging the re cessesll which are arrangedat quadrants normally prevents the body from being r0.-

tated for adjustmentor to be displaced due to the strains to which the post is subjected in use. By pressing down on the lever'9 the catch may be readily released from the body to permit same to be rotated or adjusted.

Thus .it will be seen that a multiple tool post has been provided which may be readily attached to the ordinary lathe and which may bereadily adjusted to bring-the vari-' ous tools intoposition for use, the advantages of which are already apparent in the.

art. The various parts are designed to be inexpensively manufactured and this invention presents a very this character.-
