EDGE-LINING MACHINE.

Specification of Letters Patent.

J atented Jan. 13, 1920.

To all whom it may concern:

Be it known that I, FRANK A. PHILLIPS, a citizen of the United States, residing at Northfield, in the county of Washington and State of Vermont, have invented a new and useful Edge-Lining Machine, of which the following is a specification.

' This invention relates to a machine for finishing or edge-lining the corners of a block of stone, and is particularly adapted to monumental work.

In such work it is essential that all of the finished edge surfaces-in a single face of the block lie in exactly the same plane, a result often diflicult to obtain when the different edges are finished in separate operations.

It is the general object of my invention to provide an edge-lining machine in which the oppositely disposed edge surfaces in the same face of the block shall be simultaneously finished. This method of operation substantially doubles the output of the machine and improvesthe quality of the work.

A further object of my invention is to provide a machine in which each face is cut or ground by a series of successive pairs of cutting wheels, each pair of wheels cutting a little deeper than the preceding pair,

and preferably being of slightly less thickness, thereby. providing clearance for the deeper cuts.

An important feature of my invention relates to the provision of mechanism by which the upper and lower sets of cutting wheels may be vertically adjusted by varying both the separation and the relative inclination of the sets of wheels. I further provide an effective and convenient mechanism by which the individual wheels in each set or series may be adjusted vertically in relation to the other wheels in the set.

A further object of my invention is to provide means by which the vertical edges of the block may be finished without resetting tlre block, so that correct alinement of all edges will be secured.

Further features of my invention relate to arrangements and combinations of parts which will be hereinafter described and 'more particularly pointed out in the appended claims.

A .preferred form of my invention is shown in the drawings, in which Figure 1 is a front elevation of an edgelining machine embodying my invention;

Fig. 2 is an enlarged front elevation of a portion of the machine shown in-Fig. 1;

Fig. 3 is a sectional side elevation taken along the line 33 in Fig. 2;

Fig. 4 is a bottom view of' the bearings and adjusting devices for a single wheel shaft, looking in the direction of the arrow I in Fig. 5;

Fig. 5 is a sectional elevation taken along the line 55 in Fig. 4:;

Fig. 6 is a side elevation looking in the direction of the arrow 6 in Fig. 5;

Fig. 7 is an enlarged front elevation of certain additional parts shown in Fig. 1;

Fig. 8 is a diogrammatic view showing the operation of the successive pairs of cutting wheels;

Fig. 9 is a similar view showing the way in which the separate wheel adjusting devices permit the use of wheels of varying diameters Fig. 10 is a detail sectional view of a cut made by successive wheels of decreasing I width, and

Fig. 11 shows'the appearance of a block of stone after the edges have been ground and the surplus stone has been broken off.

Referring to Fig. 1, I have therein shown one form of my improved edge-lining machine in which the operating parts are mounted upon upper and lower beams 20 and 21 supported by posts'or uprights 22' and 23 connected at their upper ends by a cross piece 24 and braced longitudinally by frame members 25 and 26. The whole structure is firmly secured togetherby tie-rods 27 and turn buckles 28, said rods being firmly secured in the concrete setting of the machine.

A pair of rails 30 extend through the machine and furnish a support for a car 31 (Fig. 3) upon which a block of stone B is supported. Suitable devices (not shown) are provided for feeding the car longitudinally of. the machine and for varying the rate of feed. These devices may be of any suitable form and constitute no part of my invention.

Each end of the beam 21 (Fig. 2) is vertically supported by an adjusting screw 32 threaded into a nut 33 forming part of a cross shaft 34 supported in-bearings '35 on the under side of the beam. A handle-.36 is loosely mounted on the upper end of the screw 32 and is connected thereto by a ratchet 37 and pawlmechanism indicated gen erally at 38. By this means the screw 32 may be rotated in either direction to raise or lower one end of the beam 21 manually, and the beam may be firmly secured in adjusted position by the clamping screws 39.

An adjusting screw 40 is similarly .connected to each end of the upper beam 20, but means is provided for turning the screws 40 by power,as the upper beam requires much wider adjustment'than the lower beam. The adjusting'screws 40 are provided with bevel gears. 41 (Figs. 1 and 7) on their upper ends, meshing with pinions 42 and 43. The pinion 42 is fixed to a horizontal shaft 44 rotatable in bearings supported by the cross beam 24 and driven through bevel gears 45 46 from a vertical drive shaft 47. This shaft is power-driven, and may be started and stopped as desired.

The pinion 43 is fixed to a second horizontal shaft 48 mounted on the cross beam 24 and alined with the shaft 44. A clutch collar 49 (Fig. 7) is fixed to the end of the shaft 48 and a clutch sleeve 50 is keyed to the shaft 44, its position being controlled by a yoke 51 mounted on a sliding rod 52 and shiftable longitudinally by manually operated mechanism not shown.

When the sleeve 50 is moved to the position shown in Fig. 7, the shafts 44and 48 are connected together and both ends of the beam 20 will be raised or lowered equally. When it is desired to change the inclination of the beam, the clutch members are separated and the pinion 42 is rotated to drive the adjusting screw 40 in the desired direction to raise or lower the right-hand end of the beam relative to the left-hand. end. When the desired inclination of the beam is thus secured, the clutch is thrown in and the beam may be raised or lowered bodily to secure the correct vertical position. As-the vertical adjustment of the lower beam is usually slight, no provision is made for simultaneously raising or lowering both ends of this beam.

The mechanism above described provides for adjustment of the upper or lower sets of wheels as a'unit, but it does not provide the necessary adjustment for each individual wheel. For this purpose I have provided the mechanism shown in Figs. 3 to 6, in

which it appears that each cutting wheel W (Fig. 4) is mounted on a wheel shaft 53 supported in bearings 54 and 55. The upper part of each bearing comprises an arm 56 angularly movable about the center of a stud 57 secured in said arm and mounted in a bearing block 58 bolted to the supporting beam 20 or 21. The bearings 54 and 55 engage shoulders on the wheel shaft, and the shafts 53 are thus positioned longitudinally by adjusting screws 59 engaging the ends of the studs 57 in the bearings 58. By means of these adjusting screws all lost motion may be eliminated, and each wheel may be exactly alined with the other wheels of the series. I

The position of each swinging arm 56 relative to its supporting beam is determined by a stud 60 (Fig. 5) threaded into the end of the arm 56 and engaging a plate 61 bolted to the beam 20 or 21. This stud may be adjusted to limit the approach of the arm 56 to the beam 20, such adjustment being retained by a check nut 62. A T bolt 63 (Fig. 6) extends through an opening in the plate 61, the lateral extensions of the bolt being circular in section as indicated in Fig. 5, and having a bearing in the inner face of the plate 61. The bolt extends freely through the plate 61 and also through an upwardly enlarged opening in the arm 56, and is provided at its lower end with a nut 64 by which the arm 56 may be drawn toward the beam 20 or 21 until the corresponding stud 60 engages the plate 61. Movement of the arm in either direction is thereafter prevented. By the provision of two swinging arms for each shaft, spaced apart a substantial distance on the supporting beam, the shafts are very rigidly held and accurate adjustment thereof may be secured.

In Fig. 8 I have indicated the operation of a series of four successive pairs of cutting wheels upon the upper and lower edges of a block B of stone fed between the wheels on the car 31. By reference to this figure it will appear that each pair of wheels increases the depth of the cut made by the preceding wheels. In order that clearance may be provided for the wheels making the deepest cut, I prefer to decrease the face of each successive pair of wheels. The nament would be impossible, but by the use of the adjusting means herein shown and described the wheels can be arranged as shown in Fig 9, in which a series of wheels of different sizes are adjusted to produce the same result as is attained by wheels of uniform size in Fig. 8.

The mechanism thus far described provides for finishing the longitudinally extending edges of the block. It is commonly necessary to finish also the vertical end edges of each face, and for this purpose I provide the vertically movable cutting wheel W shown in Fig. 1. As the vertical cut is usually comparatively short, the feed of the wheel is accomplished manually by a hand wheel 65. The same wheel is used for making the vertical cut at each end of the block, and as these cuts are made before the block is moved from its original position upon the car the four cuts will be found accurately disposed in the same plane if the wheel shafts are properly adjusted longitu dinally.

The several wheels in each series may be driven by belts 66 and 67 (Fig. 1), each belt passing around a series of guide pulleys 68 and a series of driving ulleys 69 on the separate wheel shafts. T 1e belts 66 and 67 may be driven from any suitable source of power, as is also the belt 7 0 for the wheel W.

After the edge cuts on one face of'the block are completed, the remaining portion of the stone is broken away, producing a finished face having the appearance shown in F ig. 11.

Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1. An edge lining machine having, in comto simultaneously adjust both ends of the upper support vertically.

3. An edge lining machine having, in combination, upper and lower sets of grinding wheels disposed in a single plane and engaging opposite faces of the work, and means to vary both the vertical position and the relative inclination of each set of wheels.

4. An edge lining machine, having, in combination, a series of wheels, a support therefor, means to raise and lower said support, and means to adjust each wheel separately relative to said support, said means comprising swinging bearings for each wheel mounted on said support, means to move each bearing toward said support, and stops to limit such movement.

5. An edge lining machine comprising upper and lower sets of grinding wheels, and means to feed stock between said wheels, said wheels engaging said stock in successive pairs, and each pair being of less thickness than the preceding pair.

6. An edge lining machine comprising upper and lower sets of grinding wheels, and means to feed stock between said wheels, said wheels engaging said stock in successive pairs, and the wheels of each pair having their cutting edges more closely adjacent than the wheels of the preceding pair, whereby successively deeper cut are made.

7. An edge lining machine comprising upper and lower sets of grinding wheels, means to support a block of stone as it is moved past said wheels, and means to adjust the wheels axially, whereby all of the wheels may be made effective to operate simultaneously in a single plane.

8. An edge lining machine having, in combination, a plurality of wheels, a separate driving shaft for each wheel, a separate set of bearings for each shaft, and mean to independently adjust each shaft and its associated set of bearings axially, whereby the axial position of each shaft and wheel may be separately determined.

9. An edge lining machine having, in combination, a plurallty of wheels, a driving shaft for each wheel, separate bearings for each shaft, a support to which saidbearings are pivoted, and means engaging the pivot of each bearing adapted to adjust said pivot and bearing axially, whereby the corresponding Wheel is axially positioned independently of the other wheels.

In testimony whereof I have hereunto affixed my signature.

FRANK A. PHILLIPS.
