FREDERICK J. BREWER, OF CLEVELAND, OHIO:
MULTIPLE-TOOL HOLDER. i
I Specification of Letters Patent.
Patented .rune 1e, 1908.
Application led'october 31, 1907. Serial No.- 400,157.
To all 'wlwmfitmay concern:
Be it known that I, FREDERICK J. BREWER, citizen of 'the Unitedv States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certaln new and useful Improvements in Multiple-Tool Holders, of which the following is a specification,
This invention relates to tool holders for lathes, and specially to .holders or posts ada ted to supporta plurality of tools.
e advantage of such a holder arises from the fact that by having several tools on one post, delays incident to changing tools are avoided.
'The object of the present invention is to provide a holder of im roved-construction in which the various tools vwill be firmly held, with means for varying the vertical angle of any one ofthe tools, as well as the horizontal angle incident to the rotation of the holder, to bring the several tools into o eration.
y The invention is illustrated 1n the accompanying drawings, in which Figure 1 is a top plan view of the holder. Fig. 2 is a verticalsection on the line 2-2 of Fig. 1. Fi 3 is a 'vertical section on the Fig. 1. Fig. 4 is a horizontal section on the line 4-4 of Fig. 3. Fi 5 is a vertical sectionon the line 5-5 of i 4. v
Fig. 6 is a side elevation of one of the s oes on which the tool is clamped.
Referring specifically to the drawings, 1 indicates the base of the tool post, consisting of an .elongated rectangular block having shoulders 1a at each side which iitlin the T- groove of the-slide rest of any ordinary machinists lathe.
2 is a stud or bolt which screws into the base 1 and isheld from turning out by a small pin 30.
ter a sleeve 3EL 3 is a lower Vclamping plate or part which is circular in outline and which has at vthe cenwhich is arranged to rotate on saidbolt to bring the desired tool into operation. The plate has a central .circular recess on the under side, in which ts a raised collar 1b on the base block.- ln its bottom face the plate 3 has four point-entered holes at quarters, to receive the oints of the guide pins 27 which are yieldingly supported in the base block 1 ltransmits the pressure oi" and are clamped in pl which ts over the bolt 2, and
by springs- 28, and which'by entering the holes serve to set the holder at the., proper radial adjustment.
4 indicates an upper clampingl late which is also circular in outline and whlc has a central'o ening through which bolt 2 extends. Said p ate rests on top of the sleeve 3Et and is rotatable on the central bolt. The plates 3 and 4 are connected by four stud bolts 11 located near the outer edges of the plates and provided with nuts 15, whereby the upper and lower plates are firml held together.
5 denotes a sleeve whic iits-` over the cen tral bolt 2 above the plate! 4 and receives the pressure of a nut 6 which screws on the upper end of thel central bolt 2, and said sleeve said nut so that when the nut is tightened the rotatable parts are clamped to the base plate and prevented from turning while in\use.
'litre post 1s adapted to hold four tools, and eac groove 8 formed in thlb lower clamping plate 3. The shoes are convex on the bottom, and the grooves are concave with' similar curvature so that the shoes rest in the grooves and tool rests upon a shoe 7 which iits in a may be 'adjusted forwards and backwards therein to var the vertical angle or elevation of the tools.- The ooves 8 are located on all four sides ofthe flrtriwer plate, with respect to the central post, so. as to form a square around the post with the grooves crossing each .other near the ends thereof.
YThe shoes 7 are cut off at. one end, as indiso that the shoe in one groove cated at.- 7, will not extend at its rear end across the groove ata right angle thereto, and consequently will not interfere with the shoe in the other groove. As stated, the tools, which are indicated at 40, rest upon the shoes 7,
19, of which there yare eight, or two'for each tool, so that each tool is engaged by two screws. The screws are tapped through the upper plate 4, in line with the grooves thereunder. The screws 19 are arranged symmetrically around the central post and over the grooves, with one screw'at each corner, or intersection., and one intermediate screw on each side, so that the shoes can be turned end for end in the`same grooves, which will allow the operator two ways to direct or ace `by means of screws point the cutting edge -of each. tool. Thus,
. in boring he may point the tool in one direcl tool, in either position, will be engaged by tion, as with the head of the lathe on his left hand side, while for turning, with the head on his left hand side, he can point the tool in the opposite direction. The screws 19 are hardened, so as tohold the tools firmly, and each two screws..
In order to turn the holder to bring any desired toolpinto operation, 'the nut 6 i's loos-- fened, and the clamping. plates and the tools held therebetween can then be rotated on the central bolt 2 to the desired position, being stopped or guided at each quarter by the plns -27-to bring the tool in'to proper alinelment; and' whenV adjusted asdesired, the
holder is fixed by tightening the nut 6. Each tool is independently adjustable to .vary its vertical angle, by means of the slide shoes 7, and is held at adjustment by the appropriate clamping screws 19.
Although the device is shown as capable of holding four tools, by means 'of four'sets of` clamping devices arranged at right angles" to each other,it ma be modified to hold a l l greater or lesser num er of tools, for instance,
by having a different number of grooves arranged atequal angles according to the numthe upper face,th ereo ally around the center, and clamping bolts s i 50 ber, and provided with appropriate clampin devices.
claim: y 1. In a multiple tool holder, the combination of upper and lower plates constructed to receive a plurality of tools therebetween, a central clamping bolt extending through the plates and formin a pivot therefor ,screw bolts tapped through the Yupper plate over the grooves.l v v In testimony whereof I do affix my signature, in presence of two witnesses. y
