GEORGE w. HENRY, or NEW YORK,'JN. Assi'cNoR To. E GAR BoIssIER, or GREAT NECK, NEW YORK. I

' TOOL-HOLDER To all whom it may concern: I

B'e it known that I, GEORGE W. HENRY, a citizen of the United States, residing"at Ridgewood Heights, borough of Queens,

city of New York, in the county of Queens and State of New York,;have invented certain new and useful Improvements in Tool- Holders, of which the following is a specification.

mentioned, which is simple in construction, strong and durable, is serviceable to hold tools projecting fromthe end of the tool holder as well as. various constructions .of. tools projecting laterally from the tool holder. and tools mounted upon a transverse pin or support held in the tool holder.

In" the accompanying drawings in, WhlCh' like letters of reference indicate like parts in all the figures z Figure lis a side view ofone embodiment of my improved toolrholder. I

and others broken away. I

Fig. 11 is a plan view of the holding clamp for the parting tool or other cutting tool, shownin Figs. 8,9 and 10.

The tool holder is composed of-fa shank 1 made in theshape of a shank of a tool such as iscommonly used in lathes, planers, and I so forth. Atone end this shank is provided with, a head portion 2. made integral with the shankand which shank and head can be straight as shown in Figs. 5, 8 and 9, or

can be offset as shown in Fig.1. The bottom edge. of the tool holder and the head; P F fi Pre ra ly: orm 0 -1 9, .t .-1 s

312 and the-threaded hole 13.

straight line as indicated at 3.-in Figs. 1 and 3.' Ahole for a cutter 4 extends from the end ofthe head to the side of the shank and is inclined downward as shown,so that anordinary lathe tool5 which is placed into Specification of Letters Batent. i Patented Dec. 3, 1918. i

this hole for a cutter, projects from the end, surface of the head upward at an inclinationl The hole for a cutter 4 is intersect ed-by a second hole for a cutter 6', which extends through the head 2 from one side surface.to nanotherwand intersects the hole for a cutter l in the bottom surface of the ;same, as indicated at 7, so that the tool or part ofa. tool can be placedinto said trans,

verse hole for a cutter 6 and held transverselyxto the tool 'holder, for example a tool 9 of Fig.,.5. or the tool supports 10" and 11 of Figs. and 7,:which will bedescribed later.

.The holefor a cutter 4 terminates in a re- 1 cess l2 initheupper part of theen'd'surface of the head, {so that this recess communiv cates with lthe longitudinal hole, for a cutter 4 and the transverse. hole for. a cutter 6. A screw, threadedihole 13 extends downward fro1n,.,the top edge of thehead 2 to the top of the holefor a cutter 4 and in this threaded hole there is mounted a screw The screw 14 14 for clamping the parts. has a polygonalhead 15 for applying a'key, and directly. below the head is provided with a bearing shoulder 16. A clamp'17is provided with a downwardly projecting jaw 1' 18 at'jone end, which jaw can pass through the recess 12 V, and into the transverse hole fora cutter 6iand is in front of the partition 19 formedbetween thebottom of the recess The undersideof-the body ofthe clamp 17 is finished off straight, as shown .at20, and at the inner endof a straight portion 21 on the top 1 of the head a shoulder 22 is formed, so

.that whenthe clamp is placed on the ,top of the head, with. its lug, inthe recess 12 and the end ofthe lug in the transverse hole forja cutter 6, the end edge 23'ofthe clamp rests against the shoulder 22. which forms an abutment. The clamp is raised from the top of the head, except at its end 23, bythev jaw '18, engaging the tool and the pressure of the jaw on the tool is produced by the shoulder 16 on the. screw.

Theclamp'is provided with a smooth hole 24 extending from top to bottom and of sufi ioient sizefor thescrew 14 to pass freely through the same. If the tool 5' is inserted. in the tool holder sofas. to PI'OJBCE from the end of the head athe main portion ozfiSaid" tool rests within the hole for a cutter 4. and is clamped in the same by means of the clamp, the lug 18'of which ispresse'd on the upper surface of'said tool by the screw 14 which is drawn up tight. The tool 5 can be adjusted inward and outward to project a greater or less distance and a tool can be firmly {and securely held if it is only of sufiicient length to pass into thehol'e. for a in Fig. 9 and in such cases the tool holder cutter as far as the lug or jaw '18 of the clamp and thus the smallest pieces: of tool steel can'be used, for example as short as one inch.

' If the tool is of gre'ater lengthfitsbit end can' 'project from the end of the tool holder as shown in dotted lines. in Fig.1, and the inner end can project from the end of the hole for a'cutter 45 and beyond the sides of the'shank, at'an inclination. When the tool holder ismade straight and without an ofi'set, the hole for a cutter 4 extends to' the underside of the tool holder," as shown can project from. the. underside voiiii slie shank:

I When the tool ism be held laterally to the tool holder, the transverse hole for a cutter 6 is used and the tool is adjusted in the same to project a greater orless distance beyond one side'face of the head, and the tool is then clamped by means of the'jaw-' 18,jwhich engages the too1, -whi1ch n1a'y be square, polygonal,or round in cross section. Theclamp ispressed' down by means of the screw ltfi-n.

the manner previously described. -For the purpose of holding a knurl or othertools, a

tool support 10 is placed into the transverse hole for a cutter'6 and held by means of the clamp in the manner above vdescribed,

1 the-said supportbeing preferably. provided witharecess-QG, into which the lug or jaw 18' of the clamp engages. This stud can'be provided with Decks 2'? on itsends, onwhich necks the gkn'url holder 28 for thelfmurl 29 is fastenedby means of .a screw '30. A f thread cutting tool or any'other cutting tool 31 may be mounted on aineck of a tool'support 11, as shown in Fig; '1'.

To prevent this cutter'f'rom turning and also-tobring'it to the proper angle, a block 32 having a square hole for receiving the squared part of the support 11',- is Tfirst slipped on the support 11 and a screw 33 mounted in the block 32 bears upon the edge oi the cutter 31 so as to keep it from turning around, and at the proper angle. t

For the purpose of holding a partingtool or other cuttingtool, the head of the shank is provided with a bottom .fla g 35: whi h projects laterally; the top or which flange forms an inwardly tapered or inclined $110111- deliv 361-. A cutter or partjng teal; ssrests onthis shoulder 36 and "itsiipper edge "39 is, clamping bloclr 7 4:0 which is passed through the .transverse hole for a cutter The clamping block 40 is provided "at one end with alug 41 which projects beyond said end, at the top of the tool, and has its bottom edge beveled so astoengage the upper-edge of the cutter 38. Theclainp;

ing block 40 is providedin' its upper surface with a'rec'ess 42 which can beentered by the jaw 180i the clamp 17.

Having described my invention what. I- V claim as new and desire to secure by Letters Patent is'z 1'. A tool holder consisting of ashanle terminating in ahead and havinga hole for a cutterextending lengthwise through the head portion and a hole for a cutter-extend,

ing transversely through "the head 1 portion,
