Application med December 9, w1901.- seri'el Ne. 85,137. (Ne meer.)

'To all whom t may concern@ Be it known that I, JOSEPH T. ZIKA, arcitiv- Zen of the United States, residing at Cleve-'- land, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ooping-,Machines,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings. J

This invention relates toV a machine which will probably find its greatest field of useful-Y ness in grooving the ends of bars forming parts ofwindow-sashes, so that the ends so grooved will fit the molded faces of the railstile andthe 'other bars Vforming constituent The bars to be so angles to the sides, and on bars to be used in so-called cut-up windowsashthese -ends Y in a suitable undercut groove or way a in the may be at almost any angle to the sides. It'is not the intention, however, to necessarily` limit the invention to this particular use. e

The object of the invention is to provide an efficient machine with which to groove the ends of bars, whatever may be the angle at which said ends lie to the sides, and to do this work quickly and accurately.

The invention may be here summarized as consisting of the construction and combination of parts hereinafter described, and pointed out definitely in the claims.

In the drawings, Figure l is a front elevation of a machine embod-yingmy invention. Fig. 2 isa plan View thereof. Fig. Sis a vertical sectional view in the plane indicated by line 3 3 of Fig.y 2. Fig. 4 is a perspective View of the front end of the slide on which the tool-carrier is to be secured. Fig. 5 is a perspective view of said tool-carrier. Fig. 6 is a v perspective view of a tool-to wit,fa coping-V ch-isel-adapted for use in the machine; and Fig. 7 is aperspective l.View of the toolclamping plate and parts which are secured thereto.

Referring to the parts by letters, A represents the work-supporting table secured upon a suitable support B. A slide O is mounted table. This slide carries the tools M and also the adjustable gages G, by which the depth of the grooves cut by the tools is regulated. Attached to this slide and forming a rearward extension thereof is a bar having rack-V `teethtupon one edge which lies beneath the adjacent overhangingedge a? of the groove,

whereby the shavings are'preVentedfrOm .falling onto the rack-teeth. This'bar must be long enough to preserve the operative engagement with the pinion d when the slide C is at either end of the table. The pinion is 'attached to the lower end of a vertical shaft4 D,`which is mounted in a suitable bearing a2 upon the table. Attached t'o the upper end of this shaft is a notched wheel d. An operating-'handleF is loosely mounted upon the shaftD and is provided with aspring-latchf l for engaging in any one ofthe notches d2,

whereby to -connect the handle with the shaft.

'Thehandle may be operated from either side of the tableand may be so operated Ywhatever positionthe slide C may be in.

A` plurality of .guide-blocksI-I are pivoted tothe top of the table and are adapted to be adjustably secured in'any position thereon. In the construction shown the guide-faces of these blocks are in planes which pass, respec' k.

The topjsnrface of the slide C, near its front I end, is inclined, and the lower surface ofthe tool-carrier E is correspondingly inclined, lwherebythe movement ofthe carrier upon the slide raises or lowers the carrier, and thus adapts the machine to work on bars of various` widths; .There is a slot e through the carrier Y E through which passes a screw J, screwing into the slide, whereby when the `carrier is once adjusted it may be securelyifastened.y

A set screw K, screwing through the .upi turned rear end c? of the slide, abuts against the carrier, and thus affords means for nicely adjusting it.

loo

plate N, having grooves n on the under side of its overhanging edges, and when this plate is secured upon the block it will securely hold two cope-chisels M, the edges of which are dovetailed to fit the grooves 'n and e3. Secured to the sides of this plate are gagesprings G, which are adjusted by means of screws g, screwing through the two tailpieces n' of the plate N and abutting against the inner faces or the said springs.

In using the machine the several guideblocks I-I are adjusted and secured at the proper angles, so that the ends of the bars to be grooved and which have been previously cut to the same angle will be parallel with the path of the tool when the sides of said bars are held against the guide-faces of said blocks. The gage-springs are adjusted so that the ends o'f the said bars will, when they lie against said springs, project beyond the tool a distance equal to the desired depth of' the cut. Then the operator, who with one hand is holding a bar to be cut with its side against the proper guide-block and its end against the gage-spring, takes hold of 'the handle with his other hand and by operating it moves the slide and parts carried thereby so that the chisel M will out the end of the bar. The handle can be tirst moved into whatever position is most convenient for the operator and then locked to the shaft, as described.

IIaving described my invention, I claiml. In a coping-machine, the combination of a table having in its work-supporting surface a guide-groove, a slide movable in said guidegroove, a cope-chisel secured to said slide, an adjustable gage also secured to the slide, an adjustable guide-block secured to the table, and mechanism for operating said slide, substantially as specified.

2. In acoping-machine, the combination of a table having an undercut groove in its worksupporting surface, a slide mounted in said groove, a bar secured to said slide and having on one edge, rack-teeth which lie beneath one overhanging edge of the groove in the table, a pinion engaging with said teeth, mechanism for turning said pinion, a copechisel secured to said slide, and a guide-block adjustably secured to the top of the table, substantially as specified.

3. In a coping-machine, the combination of a table having a guide-groove in its work-supporting face, a slide mounted in said groove and carrying a tool-carrier which has an outwardly-projecting grooved shelf on its side, a clamping-plate secured to said tool-carrier and having a groove in the under side of its overhanging edge, a cope-chisel having dovetailed flanges for engagement with the grooves in said shelf and clamping-plate, and mechanism for operating said slide, substantially as specified.

4. In a coping-machine, the combination of a table having a guide-groove in its work-supporting face, a slide mounted 'therein having an inclined topface, a tool-carrier having a beveled lower face which rests upon the beveled face on the slide, and laterally-extended shelf having a groove in its top surface, a setscrew for fastening the tool-carrier to the slide, a clamping-plate secured to the top of the tool-carrier and having a groove in the under side of its overhanging edge, and a cope-chisel having dovetailedn flanges for engaging in said grooves, substantially as specified.

5. In a coping-machine, the combination of a table having a guide-groove in its work-supporting face, a slide mounted in said guidegroove, a tool-carrier upon said slide having a laterally-projecting longitudinally-grooved shelf, a clamping-plate secured to said toolcarrier and having a groove in its overhanging edge, a cope-chisel having dovetailed langes for engagement with said grooves, a

gage-spring secured to the sliding member, and a set-screw in the clamping-plate engaging with said spring to adjust it into various positions, substantially as specified.

6. In a coping-machine, the combination of a table having a guide-groove in its work-supporting face, a slide movable therein, mechanism for operating it, a tool-carrier upon said slide having on its sides longitudinal shelves, a clamping-plate secured upon said tool-carrier and overhanging the saine at both edges and having two rearwardly-projecting tailpieces, cope-chisels clamped between said clamping-plate and shelves, two gage-springs secured to opposite sides of the clampingplate, two set-screws screwing through said tailpieces and engaging with said gagesprings, and a plurality of adjustable guideblocks secured to the face of the table on opposite sides of the guide-groove therein, substantially as specified.

7. In a coping-machine, the combination of a work-supporting table, a tool-carrier movable in a guideway upon said table, anadjustable gage secured to and movable with the tool-carrier, an adjustable guide-block upon the table, and mechanism for operating said tool-carrier, substantially as specified.

In testimony whereof I hereunto al'ix my signature in the presence of two witnesses.

JOSEPH l. ZIKA.
