MACHINE FOR SCOOPING WEDGES FOR PLANES.

SPECIFICATION forming part of Letters Patent No. 431,380, dated July 1, 1890. Application filed February 15, 1890. Serial No. 340,540. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH A. MONTGOM- ERY, of Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Machines for Scooping Vedges for Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in machine for scooping wedges for planes; and it consists in certain features of construction and in combination of parts hereinafter [5 described, and pointed out in the claims.

In the accompanyingdrawings, Figure 1 is a side elevation of my improved machine. Fig. 2 is a plan. Fig. 3 is an end elevation. Fig. 4 is a plan of the finished wedge. Fig. 5 is an edge view of the blank wedge. Fig. 6 is an elevation in longitudinal section, showing the wedge after it has been scooped or recessed. Fig. 7 is a view in perspective in detail of the movable jaw I.

2 5 The supporting-frame may be varied indefinitely. A preferable construction is shown wherein are employed two upright columns or standards A-and B, and these are connected by a horizontal top plate O. The latter is provided with suitable boxes, in which are journaled the driving-shaft D, the latter being provided with driving-pulley D and crank d. The section of plate 0 that overhangs the standard or supporting frame is provided with Ways 0 c, on which ways is mounted the reciprocating cross-head E. A pitman d connects the crank and cross-head for reciprocating the latter. Standard A has a vertical recess on the face thereof, the end walls of the recess a a being undercut and serve as ways for slide F. For moving the slide up and down is provided a screw-rod G. A journal for the upper end of the screw-rod is provided, preferably, as shown in the head of arm F, the

latter projecting from the face of the slide. This arm may be integral with the slide, or may be bolted to the latter, as preferred. Screw-rod G is provided with a hand-whee1 9, located so near the top of the screw-rod that it is convenient to the operator in feed ing the work.

'but is done at a subsequent operation.

The screw-threaded section of this rod engages nut ct, the latter being constructed in the head of arm A. This arm may be integral with standard A, or may be fastened to the latter, whichever way may be preferred.

. A tilting table comprising upright and lateral members II II is pivoted to the slide by means of pin or stud f, the axis of this pin being preferably in line'with the top surface of member H of the tilting table. Member II is provided with a curved slot h, the slot having as a radial center the axis of pin f. A stud h operates in this slot, the stud screwing into a threaded hole in slide F. The stud may have a head outside member H for engaging the latter, but preferably this end of the stud is screw-threaded and provided with a nut h for clamping the tiltin table against the slide to hold the latter in its adjusted position. By loosening this stud or nut the table may be tilted to the desired angle. Member H extends an inch or so above the top surface of member H, this upward extension serving as a stationary jaw for the clamp. A movable jaw I is operated by screw 2', the latter being provided with a hand-nut t", that engages the outer end of hub I of the movable jaw this hub having a hole that receives the screw loosely.

A spring 1' is coiled around the screw between member H and hub I and abutting both. This spring is compressed, inclosing the clamp, and when nut 2" is loosened the movable jaw of the clamp is backed off by the recoil of this spring. Screwt' is rigidly secured to member II. 1

In Fig. l is shown the plan of a finished wedge J, of ordinary construction, for securing the plane-iron in the plane, and Fig. 6 shows 0 a longitudinal vertical section of the same.

Fig. 5 shows an edge View of the blank wedge J before it is scooped or recessed. This machine is for scooping out the recess, whereby is provided a sunken face j. (Shown more clearly in Figs. 4 and 6.) The pointing, as shown at jj, is'not done on this mach il ile,

blank wedge J is secured in the clamp with the point or thin edge thereof presenting too a way from the cross-head. The tilting table is adjusted and secured in position to bring the finished sunken face j on a horizontal plane. A suitable tool or chisel K is secured to the cross-head, the tool projecting lengthwise thereof, this tool being of the same width as the recess that is to be cutthat is to say, of the same width as the finished sunken face j. Before placing the blank wedge in the clamp the slide and tilting table, by means of screw G, are lowered, and then the screw is used to feed-the work up to engage the cutting-tool. The cross-head bearing the cuttingtool reciprocates with great rapidity, so that the scooping of the wedge is done in a second or two, and as it requires but a moment to clamp and release the work the whole operation is the work of a few seconds of time, the capacity of the machine being about ten wedges per minute.

The scooping heretofore has been done by hand, and was slow and expensive, and not entirely uniform, and the thin side walls of the wedge were frequently split or broken. By means of this machine the work is done much better and more uniform than it can be done by hand, and the cost of the scooping is reduced to a minim um, the cost thereof being but a small fraction of the cost of handscooping.

WVhat I claim is 1. In a machine for scooping wedges, in combination, a supporting-frame bearing a reciprocating cross-head and bearing a slide adapted to move at right angles to the movement of the cross-head, a screw for operating such slide, a tilting table mounted Wholly on the slide, such tilting table having clampingjaws adapted to hold the Work, and means for clamping the table against movement on the slide, substantially as set forth.

2. In a machine for scooping wedges, in combination, supporting-frame having an overhanging section bearing a horizontallyreciprocating cross-head, the latter carrying a cutting-tool, a crank-shaft and pitman for operating the cross-head, a slide having a vertical movement, a screw for operating the supported by the slide with means for holding the tilting table in adjustment, such tilting table being provided with clamping-jaws for holding the work, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this th day of January, 1890;
