MACHINE FOR BORING AND GROOVING SASH-STILES.

SPECIFICATION forming part of Letters Patent No. 289,497, dated December 4, 1883.. Application filed September 26, 1883. (No model.)

To all whom it may concern:

Be it known that I, J GEN T. Brnnns, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Boring and Grooving Sash-Stiles, of which the following is a specification.

The object of my invention is to provide an improved means whereby the boring and grooving of window-sash stiles for the attach, ment to the same of the sash-weight cords may be accomplished accurately and with much more rapidity than heretofore.

The invention consists in the construction and combination of the various parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a vertical section of a sash-stile boring and grooving machine embodying my invention, the section being taken on the line 00 m of Fig. 2. Fig. 2 is a plan view of the same. Fig. 3 is a partial section taken on the line y 7 of Fig. 2, and showing the grooving-saw. Fig. 4 is a section of the grooved and bored portion of a stile, and showing in dotted lines the positionof the drill and drill-guide while boring the horizontal hole through which the cord is inserted. Fig. 5 is a side View of a portion of the stile completed; and Fig. 6, a longitudinal section of the same, taken on the line 2 z of Fig. 5.

A is the frame of the machine. B is a counter-shaft mounted in suitable hearings on the frame A, and receiving its motion, by means of belt a and pulley b, from a main shaft ar ranged somewhere in the buildingwhere the machineis placed. The drill-shaft is arranged on top of the frame at right angles to the shaft B, and receives its motion from the said shaft by means of a pulley, b, and a quarterturned belt, N, which latter runs up over and around a pulley, 0, upon the drill-shaft 0.

i The shaft D of the ordinary wabblesaw, d, by which the groove in the sash-stile is out, is mounted in bearings underneath the top of the frame A and parallel with the shaft B, from which latter it receives its motionby means of a belt, I), which runs over pulleys b and d, secured on the shafts B and D, respectively. The saw d is one of the ordinary wabble-saws set at a slight inclination to theaxle, so that, in revolving, it will cut a wider space than its own thickness. In order to regulate the depth of the cut by which the groove in the stile is made, a separate feed-board, d hinged to to the top of the frame, as shown in Figs. 2 and 3, and a set-screw, (1 passing through the top or table from the under side thereof, serves wherewith to regulate theinclination or height of the feed-board (Z and consequently the depth at which the saw will cut into the stile, the latter being held down upon the feed-board d while the groove is being out. At the side of the saw d a guide-board, d, is attached to and adjustable upon the feed-board, to regulate the distance of the groove from the edge of the stile, the latter being placed simultaneously against the board d and guide (2 while the saw is operating upon it. In boring and grooving the stile E, (see Figs. 4., 5, and 6,) the sockets e and e are first bored, then the groove e is cut, and finally thehole 6 between the sockets is bored, through which the sashweight cord is inserted, as in Fig. 6, and a knot tied on its end to prevent it fromtslipping out. i r

F is the drill by which the sockets e e are bored, and G the drill by which the hole 6 is bored. These drills are attached to opposite ends of the same drill-shaft, G, (which latter is revolving in suitable bearings, c, on the top of the frame A,) both ends of the shaft 0 being socketed to receive the drill-heads, and being threaded on the outside, slightly coneshaped and split, and provided with tightening-nuts c for the purpose of holding the drills, in the same manner as is usual in drill-chucks. In boring the sockets, the stile is placed upon the table f and pushed up against cleats or stops f, by which the depth of the socket is regulated. The drill G, by which the hole 6 is bored, being necessarily very long, (as it has to reach through the full length of the groove 6 and, in addition thereto, the distance between the two sockets) the manner in which I have mounted and guided the drill is the most important feature in this construction. Heretofore the holes 6 have always been bored by hand, which is not only tedious and liable to get the hole not always in the same position, but also liable to the difficulty 6 in the manner indicated in dotted lines in Fig. 4. In boring-the'hole e ,the stile is entered between three gage-blocks or guides, H H I, the two gage-blocks H being arranged one at either side of the stile, and adjustable and securable in position by means of slides h and set-screws h, and the gage-block I being arranged above the stile and adjustable by means of slots 2' and bolts i between two brackets, J, arranged one on each side of the block I, as shown in Figs, 1 and 2. The boards H H I are made adjustable for the purpose of adapting them to act as guides for stiles of different sizes.

K is a leaf hinged to the front edge of the top of the frame A, so that it may be swung down when not in use, and is supported,when in use, by means of abrace, L, hinged to one of the cross-bars between the frame-legs, and stopping with its upper end against a cleat, Z, underneath the leaf K, as shown in Fig. 1. When a stile E is'being operated upon by the drill G, its outer and main portion is resting upon the'said leaf K, which latter, for this purpose, should" be so'xhinged as to be flush with the surface which receives the inner end of the stile, as shown in Fig. 1.

In using the machine,the stile is first placed v (ing-thetalole f and the sockets e 'c: bored-by meansfo f the drill F. It isthen-plaeed upon 40 the' feed-board d and the groove 6 cut by the w abble saw d, and, finally, the hole e is bored by the guided drill G, as aforesaid. Having thus described myinvention, I claim as new and'desire to secure by Letters Patent- 1. In a stile-boring device,a drill, G,'having one or more bearings, '9, along its shank, the said bearings being adapted to "enter the groove 6? of a sash-stile when boring the hole 6 for insertion of the sash-cord, substantially as set forth.

2. The combination of the drill G, revolving in bearings 9 within the groove 6 of the stile, with the adjustable side guides, H H, and top guide, I, substantially as hereinbefore set forth.

' 3. The drill-shaft 0, having a chuck at. either end,jin combination with the socketdrill F and cord-hole drill G, the latter being centered'in bearings g, substantially as and for the purpose set forth.

4. A sash-stile machine having the socketdrill F and cord-hole drill G arranged upon the same axle, and the groove-cutter d arranged'at the side thereof, for the purpose of JOHN T. BIERDS.
