ALEXANDER MCKAY, OF VANCOUVER, CANADA.

MACHINE FOR MANUFACTURING PANEL-DOORS.

SPECIFICATION forming part of Letters Patent No. 464,581, dated December 8, 1891.

Application filed March 19, 1891. $eria1No. 385,695, (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER MCKAY, of Vancouver, in the Province of British 00- lumbia, in the Dominion of Canada, have invented certain new and useful Improvements in Machines for Manufacturing Panel-Doors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

My invention, which will be hereinafter fully set forth and claimed, relates to machinery for manufacturing panel-doors by means of doweling.

Figure 1 is a perspective view of my improved door-doweling machine. Fig. 2 is a vertical longitudinal section showing one of the boring-heads in elevation. Fig. 3 is a cross-section on line m :20, Fig. 2; and Fig. at is a detail.

A A are two stands connected by tie-rods a a to form a machine end orframe, two such ends being used.

A A are two stands carrying the setting mechanism.

In the stands A are secured two transverse rods B, upon which the boxes C are adapted to slide for the purpose of being adjusted thereon in any desired position or distance from each other by tightening the bolts 0, Fig. 4:. The boxes 0 are compound, and, besides having bearings for the rods B, have journaled in them the shafts D, and have also secured in them the ends of the guide-rodsF. One of these hearings is shown separately in Fig. 4. The shafts D are each provided with a pulley D, which is driven by a belt D from above or below, as shown in Fig. 2. The shafts D have each key-bed d nearly their whole length and carry each a pinion E, adapted to slide thereon and be rotated by a key fast on said pinion and engaging a groove or key-bed.

G G are the two blocks or ends of a carriage, adapted to slideupon the guide-rods F. In these are j ournaled a series of spindles G, each having upon it a pinion G, all of which in the series gear together androtate said spindles, the central one being geared into the pinion E, as shown in Fig. 3. Spindle G is also provided with a drill-socket g for the insertion of a bit II. The ends G are c0nnected below by a rod or bar I, which extends forward beyond the outer box 0,. on which it is carried, and terminates in a rack I, gearing into a pinion J, which is mounted upon a shaft J, provided with a hand-wheel J and journaled in the stands A. By turning the hand-wheel J, and thus rotating the shaft J in one direction or the other, the carriages G are moved on the guide-rods F forward or backward, the pinions E moving with their carriages and sliding on their shafts D. The shafts D may be set any distance apart on the rods B, and there may be any number of them that can be contained on the length of said rods. Each carriage G G may also be constructed to carry any number of spindles desired.

Two machines may be placed oppositeeach other, with one common propelling-shaft J between them. The pieces to be doweled are placed across the rods F and the carriages G G and bits I-I propelled toward and into them by turning the hand-wheel J while the shafts D, and with them the bits H, are rotating.

I claim as my invention* 1. Ina machine for doweling panel-doors, the combination of suitable frames supporting a pair of guide-rods B, the compound boxes 0, supported adj ustably on the guides B, and each pair of opposite boxes holding two guide-rods F and having a shaft D journaled therein, having pulley D, long key-bed d, and pinion E, the guide-rods F, supporting sliding carriages, blocks G, connected in pairs by the rods I and forming said carriages, and a series of drill-spindles G, journaled in said block and carrying pinions .G, geared together and one of them gearing into the pinion E, substantially as set forth.

2. In a machine for doweling panel-doors, the combination of suitable frames supporting a pair of guide-rods B, the compound boxes 0, supported adj ustably on said guiderods, and each pair of opposite boxes holding two guide-rods F and having a shaft D journaled therein, having pulley D, long key-bed d, and pinion E, the guide-rods F, supporting sliding carriages, blocks G, connected in pairs by the rods I and forming said carriages, a series of drill-spindles G, journaled in said blocks and carrying pinions G, geared together and one of them gearing into the pinion E, racks I at the ends of the rods La shaft J, journalecl in stands A, pinions J, and hand-wheel J on said shaft, said pinions gearing into the racks I, substantially as set forth.

3. In a machine for doweling panel-doors, the combination of a pair of boxes adapted to be adjustably held on a pair of parallel rods, a pair of parallel guide-rods F, having their ends secured in said boxes, a shaft D, journaled in said boxes and having a long key-bed, means of rotating said shaft, a s1id-- ing pinion E on said shaft, a pair of blocks G, connected by a rod and adapted to slide 15 on the guide-rods F, and drill-spindles G, journaled in the blocks G and carrying pinions G geared together and inlthe pinion E, substantially as set forth.

In testimony whereof I have signed in the 20 presence'of the undersigned witnesses.
