UNITED STATES ERNST KOLL, OF CHICAGO, ILLINOIS.

MATCHING-MACHINE Application filed August 21, 1905.

T 0 all whom it may concern:

Be it known that I, ERNST KoLL, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improve ments in lVlatching-ldachines, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to machines especially adapted for the manufacture of staves, such as are used in the construction of wood columns, as, for example, the column made the subject of Patent Number 744,566 issued to me November 17, 1903.

The object of the invention is to provide means for adapting the machine to cut upwardly or downwardly in forming the grooves and tenons in the sides of the stave; and the invention consists, broadly, in a machine having its cutter heads carried by swiveled frames mounted upon saddles movable to and from the bed of the machine.

The invention consists, more specifically,

' in the construction hereinafter described and which is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the machine, the projecting table being shown in transverse section; Fig. 2 is a detail plan view of the same; Fig. 3 is a vertical longitudmal section; and Figs. 4 and 5 are details of certain parts of the machine.

The machine is provided with a supporting frame, shown in part at 10 and 11, and a bed 12 for receiving the work as it is delivered from the cutters. A pair of feed rollers 13, 14 are suitably j ournaled in the frame 10, and are driven by gears, such as 15, 16, actuated from any suitable source of power.

A pressure block 17 is pivoted, as shown at 17 to the frame 10 so as to bear upon the upper face of the stave X as it is being operated upon, and is held against upward movement by a cross-bar 18 secured to the bed 12 by means of screw bolts 19. A hand screw 20, engaging a suitable part of the frame of the machine, bears upon the top of the block 17 so that it may be given any desired degree of pressure upon the stave.

The cutter frames 21 22, referably two in number, are carried by sli e blocks 23, 24, which reciprocate vertically in the saddles 25, 26. Each of the cutter frames is secured to its saddle by a pivot in 27 so that it may be oscillated in vertica plane. The rearward Specification of Letters Patent.

plates, sliding in the segmental slots 32, 33,

and providing means for securing the cutter frames in any angular position to which they may be adjusted.

The cutter heads 34, 35, are mounted u on spindles 36 which are suitably journale in the cutter frames 21, 22, and these spindles carry the pulleys 37, 33, to which are applied suitable belts 40 and 41, driven from any desired source of power.

The stave X to be operated upon is secured to a pattern form 42 which slides upon the bed 12 and is held against lateral movement by a rib 43 rising from the bed. Staves of the character referred to are usually tapering in form, and this form is secured by the use of a pattern of similar form, and the cutter heads are moved to and from the median line of the machine by means of this pattern and the mechanism hereafter described.

A frame 44 is secured to the main frame 10 of the machine and arranged transversely thereto and provided with the cross rails 45, 46 and 47 The saddles 25 and 26 are supported by the center cross rail 46, the saddles eing provided with suitable rollers 48 which rest upon ways 49 formed in the front face of the cross rail. The saddles are prevented from upward movement by means of rollers 50 bearing upwardly against the ways 51 formed in the rail 46. The rollers 48 and 50 are held in engagement with their ways by means of bracket arms 52, 53, projecting baokwardly from the saddles and carryin the rollers 54, 55, which engage the rearward faces of the cross rails 45 and 47. Each of the saddles is provided with a bracket arm 56 extending inwardly toward the median line of the machine and carrying a roller 57 adapted to bear against the side of the pattern 42, so that the saddle is moved backwardly in its ways as the width of the pattern increases. A counterweight 58 is secured, by the cables 59, 60, turning over suitable sheaves 61, to the two saddles and tends to draw them toward each other so as to hold the rollers 57 against the faces of the pattern 42. The slides 23 and 24 are moved vertically by means of screw-rods 62, 63, engaging them and suitable portions of the frame of the machine. The cutters 64 may be of any desired form, and are secured to the heads 34, 35, so as to out the side edges of the staves to the sha e desired.

As shown, each of t e pulleys 37, 38, is mounted upon the spindle 36, in line With the pivot pin 27 supporting the cutter frame, thereby ermitting a Wide range of movement of t e cutter frames 21, 22, about their pivots Without unduly straining the belts turning over the pulleys.

I claim as my invention In a matching machine, in combination, a frame having a Work supporting bed, a pattern in sliding engagement With the bed, a saddle at one side of the bed movable toward and away from the path of the pattern, means for holding the saddle yieldingly against the pattern, a vertically movable slide block carried by the saddle, and a cutter frame swiveled to the slide block and swinging in a vertical plane.
