WORK-HOLDER FOR SHAPERS.
Specification of Letters Patent.
Patented May 2, 1911.
Application led August 17, 1909. Serial No 513,274.
c all whom it may concern:
Be it known that we, HENRY E. MoRToN and HORACE MANN, citizens of the United States, residing at Muskegon, in the countyv of Muskegon and State of Michigan, have invented certain new and useful Improvements in l/Vork-Holders for Shapers, of which the following is a specification.
This invention relates to an improved work holder for shapers or similar metal working machines and it is especially adapted yfor use in connection with the type of draw-cut Shapers shown in United States Patent No. 682, 218 to M. and H. E. Morton, for holding large castings which are to be faced upon several sides, at dierent angles and bored or milled out, such for example as heavy locomotive cylinders.
The object of this invention is to facilitate the centering, alining and adjusting the work to the shaper and to also facilitate the shifting of the work from one position to another to present at different angles the several parts of the casting to be faced or bored.
A further object is to provide a device for the purpose which is so constructed that the work will be held centered during the whole process of shaping or planing, including the shifting of the wo-rk to its several positions, thus insuring accuracy and facilitating the process, and it is also an object of the invention to provide this device with means adapted to facilitate the taking of measurements and the finding of centers, vertical and horizontal lines, etc.
To these ends the invention consists in the construction, arrangement and combination of parts, all as hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings in which- Figure 1 is a front elevation of a device embodying the invention; Fig. 2, a similar view showing the chuck turned on its aXis to hold the work in another position; Fig. 3 is a side elevation of Fig. 1; Fig. 4 is an enlarged longitudinal vertical section through the chuck and work held thereby; Fig. 5 is a side elevation showing the chuck and its bed plate turned upon the floor plate from the position shown in Fig. 2, to position the work for planing the same at right angles to the operation shown in said Fig.
This work holder is especially adapted for use in connection with a draw-cut shaper as indicated in outline in the drawings, embodying a bed plate A, a column B supporting an adjustable saddle carrying a ram C provided with a tool carrying head D, all constructed, arranged and operated substantially as shown in the said Letters `Patent before mentioned.
The shaper bed plate A is adjust-ably secured upon a oor plate 1 which is made much greater in area than the shaper bed to accommodate a bed plate 2 thereon at one side of the shaper bed. This floor plate is provided with a series of longitudinally eX- tending parallel T -slots 3 and elongated openings 4 between said slots. The T-slots are to receive bolts for adjustably securing the shaper bed and the bed plate 2 in place thereon, suitable clamps 5 being also held by bolts engaging these slots for assisting in the securing of the bed 2 in such a manner that it may be readily released and shifted upon the upper plane surface of the floor plate to any desired position. When properly located the bed 2 is detachably held against movement longitudinally of the floor plate by wedge blocks 6 between its forward side and pins in the holes 4f. Blocks 38 are also provided between plates 39 secured to the rear side of said bed and the bed A of the shaper. v
`The bed plate 2 is provided with transverse parallel T-slots 7 and detachably and adjustably secured upon this bed by bolts engaging said slots, are two bearing brackets 8 each formed with a bearing for the hub 9 of a chuck disk 10, which disks are formed in the usual way of making large chucks, with radial slots in which are mounted the ordinary jaws V11 adjusted into or out of engagement with the work by the usual adjusting screws 12. The hub of each of the chucks is held in the bearing of the brackets 8 bya cap 13 engaging the outer end of the bearing and bolts 14 passing through the caps and engaging screw-threaded openings in the ends of the hub. By turning up the bolts the chuck is drawn into frictional engagement with the bracket and thus securely held and prevented from turning too readily.
The cylinder casting 15 to be faced olf is secured to and supported by the chucks 1()k by engaging their jaws with the bore of the cylinder, thus supporting said cylinder concentric with said chucks and it is clamped between them by adjusting one bracket toward the other by means of a rack 16 secured to the base plate and a pinion 17 on a shaft, mounted on the bracket engaging said rack and turned by a suitable crank 18 applied to the outer end of the shaft. In the hub 9 and cap 13 of each chuck is an axial opening to receive a rod 19 which is put therethrough and through the bore of the cylinder after said casting has been chucked and this rod is screw-threaded at each end and provided with a nut, which nuts may be turned up against the caps 13 and clamp. the work securely between the chucks, at the same time clamping each chuck between its bracket and the end of 'the work and preventing the turning of the `tachably and. adjustably secured upon the table 20, and this supplemental table is formed to project inward over the adjacent upper edge ofthe chuck disk with. its inner edge. close to the work, so that by the use of a suitable tool, such as a square 24 shown in F ig. 3, accurate measurements may be taken and center lines quickly struck, the upper plane surface of said supplemental table being parallel with the surface of the bed 2 and a fixed distance. from the axial line ofthe chucks, which line is also the axis of the cylinder bore. Measurements may be taken` from the table 20, but in order that the square may be supported close to the Work to avoid inaccuracies, the supplemental table is provided which may be detached or adjusted as desired. A lateral extension 25 is detachably secured to the bracket 8 and forms. an extension for the table 2O from which measurements may be taken at a distance to one side of the chuck.
In. one of the slots in the tablel 20 is a bolt for detachably securing a supporting bracket 26 upon said table, said bracket being provided with a rib to engage the other slot and hold' the bracket in line. This bracket is providedy with a. T-slot in its vertical side to receive bolts for adjustably securing a bearing 27 thereto. Said bearing 27 is provided with a sleeve 28 secured therein to receive the end of a boring bar 29 which is free to rotate and to move longitudinally therein, the opposite end of said bar being attached to and rotated by a shaft 30 in the axis of the ram C.
In machining cylinder castings which are formed with an integral valve chamber such as the casting 31 shown in Fig. 7, the work will be greatly facilitated by being able to bore the chamber while the casting is in the chucks.
As illustrated in Figs. 1 and 2, the casting may be turned to present different faces to the cutting tool, by turning the chucks without removing the casting therefrom, and thus holding the casting centered throughout the entire operation, insuring accuracy and expediting the work.
Vhen castings are being planed which have heavy lateral projections such as the castings shown, detachable and adjustable `supports 32 and 33 are provided for such projecting portion, at each side of the brackets 8. The work support 3Q is held in place on the floor plate 1 by bolts engaging the t T-slots in said plate and atits upper end is yprovided with a T-slot to receive bolts for attaching an extension member 34. thereto to increase the height of the support if necessary. Arms 35 on the extension memi ber project upward at each side of the work and adjustable centering bolts 36 carried thereby engage the work and hold the same against lateral movement. At the other side of the chuck, to support the laterally extending portion of the casting when the same is turned over with the turning of the chuck, is the work support 33 detachably and adjustably secured to the bed 2 and provided at its upper end with a. T-slot by means of which an extension member similar to the member Slt may be attached when desirable. Adjusting or set screws 37 engage screwthreaded openings in the top of the support 33 upon which the work rests so that said work may be very accurately adjusted.
By mounting the chucks upon a movable bed, the work may be shifted to any desired position without removing it from the chuck, and the chucks combined with the work supports at each side thereof give a very eliicient holding means upon which thc work may be rotated to present various faces which are thereby located accurately with relation to the axis of rotation.
