Application filed February 29, 1924. Serial F lo. 696,68L'

Be it known that 1, JA a subject of the King 01" Great Britain a d Ireland, and resident oi Modern Joint or-ks, Pilling Street, Norden. llochdale, the county of Lancaster, England, have iii-- vented certain new and useful improvements Relating to Spindle-Molding Ma chines for lVood (for which I have made application for Letters Patent in Great Britain. No. 10,888, dated April 21, 1923, Patent No. 208,472), of which the following is a specification.

This invention relates to spindle molding machines and has for its object to provide simple and eiiectivc means whereby the said machines can be readily adapted for the production of the grooves in stair stringer "for the reception of the stair treads and risers or for similar repetition work.

My invention relates more particularly to that type of mechanism in which a temnlet having slots therein corresponding with the grooves to be produced in the stringer is clamped to the latter and a bracket at its outer end a downwardly pro cting spindle with a guide pin thereon which ar tends into said slot in the templet imn'iediately over the vertical cutter spindle.

My invention comprises the improved details of construction and arrangement ina'fter described and claimed.

Referring to the two accompanying sheets of explanatory drawings:

Figure 1 is a plan view of the improved templet constructed in accordance with my invention.

Figure 2 is an end view looking from the right hand upper corner of Figure 1.

Figure 3 is an-end View 0:5 part of the templet looking from the right hand lower corner of Figure 1.

Figure 4 is a detail sectional view of the upper right hand corner of the templet shown in Figure 1.

Figure 5 is a front elevation. Figure 6 an end elevation and Figure 7 a plan view of the bracket which is used in conjunction with the templet shown in Figures 1 to 1-.

The same reference letters in the different views indicate the same or similar parts.

The templet a which has the slots 5 therein corresponding with the grooves to he produced in the stringer has thereon at its opposite sides cross members or guides 0 which are adjustably secured in place; by

two studs (Z which pass through elongated slots 6 in the templet. Setting scales f. are provided adjacent the slot 7).. of the stringer bears againstthe guide 0 whilst the other side is clamped by a part it which extends to the opposite sides of templet and is guided in the latter so tha; it does not rotate but is traversed along the slot 71 by the screw j turned by the hand wheel is.

With the arrangement oitemplet described and illustrated, the guide 0 is set to suit the dimensions oi the stringer and when the stringer or stringers for say the right hand side of a stairway have been grooved, the corresponding stringer or stringers for the left hand side can J8 grooved by pla eing the stringer on the opposite side oi the templet.

The part m is clamped upon the table of the spindle molding machine by the two clamps n, 0 and carries an upright spindle p to which is secured at an adjustable height a horizontal arm q carrying at its outer end a fitting rin which can slide a vertical spindle 8 adapted to be locked in its service and out of service positions respectively by the ball catch Z as shown. The lower end of the spindle s carries a roller it which is adapted to enter the slot 6 in the templet a. '2) indicates the stringer, w the table of the machine and as the vertical cutter.

If the roller it be of the same diameter as the cutter 0a, the groove produced by the latter will be of the same width as the slot in the templet. By fitting rollers oi? different sizes relatively to the cutter the dimensions of the groove produced by the cutter with the use of the templet can be altered.

I claim:

1. In templets of the type specified, in combination, a reversible pattern. plate with pattern and securing slots therein, adjustable similar guide picces at the opposite sides of the pattern plate, means passing through slots in the plate and securing the two guide pieces simultaneously thereon, clamping means for the workpiece operative at both sides of the pattern plate, and means for adjusting said clamping means, as set forth.

2. In templets of the type specifiech'm combination, a reversible pattern plate with pattern slbtsand elongated'bolt holes therein, adjustable similar guide pieces tor one side of the workpiece at the opposite sides of the pattern plate and extending across the pattern slots, studs passing through the bolt holes in the pattern plate and securing the two guide pieces simultaneously thereon, a clamping member for the opposite side of the workpiece having a threaded aperture therethrough and extending to the 0pposite sides of the pattern plate to co-operate with the two guide pieces and to prevent its rotation, and a screw secured in the pattern plate against endwise movement passing through and adjusting the position of said clamping member, as set forth.

3. In a spindle molding machine employing a teniplet as claimed in claim 1, in combination, a metal cutting tool a table around said tool, a teinplet on said table, a guiding roller entering the pattern slots in the templet, an adjustable arm support ing said roller, and means locking said arm in position vertically over the cutting tool With the roller in the pattern slots in the templet, as set forth.

In testimony whereof I have signed my name to this specification.

JAMES FRANK ROSE.
