MACHINE FOR GROOVFNG WINDOW-SASH.

SPECIFICATION forlxllligl part f Letters Patent NO. 400,597', dated April 2, 1889.

v Application filed July 9, 1888- Serial No. 279,361. (No model.)

To @ZZ whom t may concern/.r

Be it known that I, FRANCIS V. PHILLIPS, of Chicago, in the county of Cook and State of Illinois, have invented certain new' and useful Improvements Vin Machines for Grooving Window-Sash; and I do hereby declare that ,the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the let- Io ters of reference marked thereon, which form a part of this speciication.

This invention relates to improvements in machines for vcutting' grooves and recesses in window-sash to receive and retain the sashi 5 cord in proper position, and relates more particularly to a machine for making that form of groove illustrated in an application for Letters Patent heretofore iiled by me on December 24, 1887, Serial No. 258,879.

27o The invention consists in the novel features of construction and operation herein illustrated, described, and pointed out in the appended claims. The window-sash above referred to, and

whichis also illustrated herein, embraces a Y stile having a wide longitudinal open slot or groove formed in its edge at the top, a recess for the knot undercut toward the top of the sash, and a narrow open slot or groove con- 3o necting the wide groove and the vrecess. In this construction the narrow groove is adapted to receive the cord, and the enlarged or wider groove is necessary to vaccommodate the projecting sash-pulley, and the undercut recess 3 5 is adapted to receive and retain the knot of the cord. Such a sash involves some degree of difficulty in its construction by requiring different forms of tools to make the different widths of grooves and the recess, and, fur- 4o ther, in making said recess undercut or inclosed for a portion of its length, so that the cord-knot may be inserted first in the recess and then retained therein by the inclosed portion thereof, as will be more fully hereinafter explained.

One of the objects of my invention is to produce a machine whereby both longitudinal grooves and the undercut recess may be formed practically in the same operation or 5o. with once handling.

Figure l is a side elevation of a machine embodying my invention. Fig. 2 is a plan view of that portion of the machine illustrating the cutting-heads and table. Fig. 3 is a vertical sectional view taken upon line 3 3 of Fig. 1. Fig. 4 is al modified form of the arrangement of the cutting-heads. Fig, 5 is a plan view of the face of the stile and window-sash, showing the grooves and recess as made by the arrangement of cutters seen in Figs. 1 t-o 3, inclusive. Fig. 6 is avertical sectional view of the latter, taken upon line 6 6 of Fig. 5.

In the drawings, A is the standard of the frame of the machine, upon the top of which are mounted double pillow-blocks A A.

B B are the grooving cutter-heads mounted, respectively, upon the ends of the shafts b b', which latter are journaled revolubly in the pillow-blocks A. Located upon the shafts b b between said pillow-blocks arethe pulleys b2. A third pulley, b3, is mounted upon a shaft, b4, which latter is preferably journaled in the pillow-blocks A in position below and Y between the shafts b b.

B2 is a driving-belt passing over the pulleys b2 b3, whereby power is communicated to the shafts b b and to the cutter-heads B B which are revolved thereby.

It will be noticed that by the location of the several pulleys just described the Said cutterheads B B are driven in the same direction by one belt.

C is a table secured upon the top of the frame A, and is provided with a longitudinal slot or opening, c, through which edges of the cutter-heads may project.

D isa stop secured adjustably by means of the bolt cl to a rod,.D,which latter is secured to or may be integral with the end of the frame of the machine. This stop D is provided with a vertical face, d', and a projecting extension, d2, the object of which will be hereinafter explained.

E is a vertical Shaft secured in journal-bearings e to the cross-pieces aof the standard A. Said shaft E is adapted to be moved longitudinally through said bearings e for the purpose hereinafter mentioned. Upon the upper end of said shaft is mounted a boring and cutting tool of any familiar pattern adapted to make an undercut recess. The tool herein shown consists of a round cuttin g-head, F, provided with a cutting edge or edges upon its ends and its peripheral faces and mounted upon the upper end of a neck or shank, f, which latter is of smaller diameter than the cuttinghead F and of not greater diameter than the width of the narrower groove. The lower end of the shaft E is provided with a collar, E', secured thereto by means of the screw c. Said collar is provided with two extensions or lugs, e2 e2, and said lugs c2 are each provided with an elongated opening or slot, e3.

G is a lever pivoted at g to the lower portion of the standard A. One end of said lever is provided with a treadle or foot-piece, g', and the other end of the lever G is adapted for insertion between the two lugs e2, and is provided with a hole or opening by which the said lever G may be movably secured to the said lugs by means of a bolt, e4, and a nut, e5.

H is a coiled spring secured at one end to an eye or pin, 71 upon the standard A and at its other end is secured to the lever G between the-foot-piece g and the pivot g. The power of this spring is constantly exerted in maintaining the lever G in the depressed position illustrated in full lines in Fig. l, as will be readily understood. Then the operator places his foot upon the foot-piece g and presses the same downwardly against the force of the spring H, he thereby forces the collar E upward vertically into the position illustrated in dotted lines in Fig. l, and at the same time raises the shaft E and the cutterhead F. A plate, g2, secured to the frame A by the bolts g3 or other suitable device, serves as a stop for limiting the upward movement of the cutter F.

E2 is a pulley mounted upon the shaft E, preferably between the journal-bearings c, and E3 is a belt by which the shaft E may be rotated from any suitable source of power.

I is a movable guide placed upon the table C and provided with lugs fi, each having an elongated slot, t, to receive the bolts Said bolts 112 pass upwardly through the table C, and the lugs c' are firmly held in any desired position by means of the thumb-screws The guide I may thus be moved bodily to and from the cutter-heads B B and adjusted as desired by means of the thumb-screws J is the stile of a wooden sash; j, the wide groove therein; j", the narrow groove, and J the undercut hole or recess for the cord-knot, having an overlapping portion,'j2, on either side of the groove j In the machine described the cutters B and B are of proper width, respectively, to cut the several grooves j and j', and the cutter F forms the undercut recess J The operation is as follows: The guide I is rst adjusted upon the table C to bring the cutters beneath the central line of the sashstile, and the stop D is similarly adj usted upon the rod D to determine the length of "the grooves and the position of the recess.

The end of the stile J is placed upon the table C against the guide I and is pushed lengthwise against the cutter B and toward the stop D until it reaches and is arrested by the latter. The stile will then be in the position illustrated in Fig. l, with one end closely beneath the projecting lug cl2 of said stop I). The operator will hold the other end of the stile firmly to the table C, and then press wit-h his foot upon the treadle g By this action he will raise the revolving shaft E and force the cutter-head F vertically into the stile to the position illustrated in dotted lines in said Fig. l, thus boring a hole in said stile at right angles thereto. Without removing his foot from the treadle and without releasing his hold upon the stile J, the operator will then draw said stile toward him a short distance, and while doing so the revolving head F will elongate the recess J in the stile, making the undercut shown in Figs. 5 and (3. In this last movement the neck f of the recessing-cutter passes up the groove j. The operator will then move the stile back to its position against the stop D, when he may release his pressure upon the treadle g. The spring H, together with the weight of the shaft.E, will cause the said shaft to drop, and the cutter-head F will be withdrawn from the recess which it has made in the stile. The stile may then be lifted away and another cut in the same manner.

It will be seen that both grooves, one wider than the other, and the elongated undercut recess are made at practically one operation or by once handling and at a very great saving of time on the part of the operator.

The arrangement of the recess-cutter F between the groove-cutters B and B involves the location of the recess J between the ends of the narrow groove j, or, in other words, the prolongation of said groove beyond the recess.

In Fig. 4 the shaft E is shown located in front of the cutter b. In the use of this arrangement the manipulation will manifestly be different from that above described. Usually the forward movement of the stile will be continued until the grooves are completed and the stile is then drawn back to the proper position for the recess. The cut-ter F will be then raised to cause the entrance of said cut ter. The stile will then be still farther drawn back to make the under-cut, and then advanced to bring the cutter back to the mouth of the recess, at which point said cutter is dropped out of the recess and the stile is lifted away. For this operation the lug d2 on the stop D must be made of proper length to overreach the end of the stile in the position of the latter at which the recess is formed.

I claim as my invention- 1. In a machine for grooving and recessing window-sash Stiles at one operation, the combination of a table provided with a guideway for the stile, an end-stop, an overhanging lug, as d2, one or more rotating groove-cutters in the path of the stile, and a recessing-tool mov- IOO IIO

able into and out of the path `of the stile, substantially as andAfor the purposes specified.

2. In a machine forgrooving and recessing d window-sash stiles at one operation, the com- 5 binationA of a stile-guide, two grooving-cutters of unequal thickness mounted -in yline with each other in the path of the stile, and a recessing-cutter movable sidewise with respect,-

to the path of the stile into and out of said path, substantially as described.

3. The combination of a table, revolving groovecutters B B', a stile-guide adjustably secured to the table, an adjustable end-stop having a projection which overhangs the path of the stile, a recess-cutter supported by a FRANCIS V. PHILLIPS.
