IMPRO'VED HINGE-MACHINE.

The Schedule referred to in these Lettori Patent and making part of the same.

I, JOSEPH H. BAIRD, of Oakville, in the county of New Haven and State of Connecticut, have inventeda. new and improved Machine for Automatically Gountersinking and Milling Hinge-Blanks, of which the following is a speciflcation.

General Description.

The parts which constitute the frame of the Ina-- chine,`and which support its various operative mechanism, consist of the side pieces A A and plate B, rmly bolted and secured together.

The main shaft E is' held in bearings in the sideframes A A, and operates the cams M, O, and N, secured upon it in proper position.

The first cam, M, operates the shaft F, upon which the feeders S S are adjusted.

The center cam, 0, actuates the frame D, carrying the countersinking and milling-mechanism.

The'tnird cam, N, imparts the proper movements to the clamping-jaw W.

The feeding-mechanism consists of a series of fingers, is, held in adjustable bearings e upon the shaft F, which are so operated that the blanks laid -upon the feed-plate f are fed forward to the action of the countersinksU U and cutters K K, the motions imparted to the fingers through the medium of the grooved cam M and arm P consisting of a forward, an upward, a backward, and a downward positive motion.

' The countersinking and milling-mechanism are held in bearings in the reciprocatin'g frame D, which slides in the guides C O, secured to the frame of the machine.

The countcrsinks U U are supported in the adjustable bearings V V, and, whenl raised to act upon the blank, they project through the apertures a a, immediately under the plate Y. This plate is so arranged als to hold the blanks down when they are being acted upon by the counter-sinks.

The rotary cutters K K are arranged upon the shaft J, which is supported by the adjustable arbors I I, held in the bea-rings G G upon the reciprocating frame D, and are arranged to admit of their being removed for the purpose of inserting other cutters when desired, as, when cutting blanks of a larger size, for instance, it may be necessary to employ a greater number of cutters, or others of a larger diameter.

The shafts of the cutters and countersnks are provided with pulleys L T, through the medium of which they are driven.

`Upon the plate B is held in bearings x x the shaft H, which operates the clamping-jaw W. This jaw holds the blank to the action of the cutters after it has been fed forward from the countersinks U U, and

' it is so operated bythe cam N, through the arm Q,

that the blank is clamped between its under surface and the upper surface of the plate Z at the proper moment.

The jaw W is provided also with a stop, b, which serves to arrest the motion of the blank, and-to insure of its proper adjustment in relation to the cutters.

The guide d, screwed to the frame D, acts to keep the edge of the blank always in a plane parallel with the axis ofthe cutters, and to prevent its being accidentally thrown out of position before it is seized by the clamp W.

After the blank has been acted upon by the cutters, and released by the clamp, it is dropped through the opening c by the action of the feeders in presenting another blank to the cutters.

Operation.

The blanks are rst pressed out of the proper form, with holesto receive the screws, and are then acted upon by a machine which bends the knuckles, after which they are ready to be fed to the countersinks and milling tools, which act upon them as follows The blanks being laid upon the table or feed-plate f, in regular succession, are fed forward'by the lingers S to the countersinks U. The iirst countersink acts upon the first hole in the first blank, and cuts it to the proper depth; the second vblank in the row, at the next movement of the feeders, is brought in position to be acted upon by the rst countersink, which cuts also the rst hole in this blank. As this feed movement continues, the first blank will be brought over the second countersink, so that it will act upon the second hole of the blank, and thus the rst holes in the blanks are cut in succession by the rst countersink, and the second holes by the second countersink.

The parts of the machine which guide and hold the hinges during the successive operations should be ad.

instable for hinges of. various sizes, which can easily be arranged by having slots for the screws which hold the parts, either in theparts `themselves or in the bed. 'l

As adjustable devices are ycommon to'all such machines, a further description is considered unnecessary.
