NAIL=CUTT|NG MACHINE.

SPECIFICATION forming part of Letters Patent NO. 361,744, dated April 26, 1887.

Application filed August 2, 1886. Serial No. 209,737. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWIN HUDsoN BIS- SETT, of Vinnipeg, in the Province of Mauitoba, in the Dominion of Canada, have invented certain new and useful Improvements in Nail-Cutting Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention consists of a machine having a rotary head provided with peripheral cutters to cut a tapering nail head and point alternately, an oscillating feed-table to present the diagonally-cut edge of the nail-plate parallel to the face of the rotary head at each succeeding cut, a chute having two passages for conveying the headless nails, a pair of rotary disks having peripherally a series of nail-holders to receive a nail from each chute alternately, and trip-hammers to head the'nail during the passage of the nail-holder against a fixed cam, the nail subsequently falling through an opening in the bed under the holder, all as hereinafter more particularly described and claimed.

Figure 1 is a top View of my improved machine. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation, and Fig. 4 a plan, of the bottom of the machine inverted.

1 is the main frame of the machine.

2 is a circular head keyed on a shaft, 3,

journaled in bearings on frame 1, and said shaft is provided with a flywheel, 4, belt-pulley 5, for rotating the head by belt 6, and driven by shaft 7, or other suitable means. The rotary head 2 is provided with horizontal cutters 8 in its periphery, to cut a nail head and point alternately from a nail'plate fed to the cutters.

9 isa feed-table inclining downwardly toward the rotary head 2, and on which table the nail-plate is placed, and one end of said table 9 is pivoted to a crossbar, 10, of frame 1, immediately in front of the rotary head, and plate 9 is oscillated laterally by a vertical bar, 11, pivoted at 12 to frame 1. One end of said bar 11 connects with feed-table 9, and the other end engages with a wave-wheel, 13, on driving-shaft 7, so that without overturning the nail-plate a nail will be cut therefrom,

head and point alternately, by each successive 5o cutter, and by the oscillation of the feed-table the diagonally-cut edge of the nail-plate will be brought square to the face of the rotary head, whereby a nail will be cut of the full width of the plate.

14 is a chute having at top inwardly-com verging sides, into which the nail falls point downwardly on being cut, and the headless nailsseverally strike against opposite sides of the chute alternately, and are directed by the inclined sides to slide down passages 15 in the chute alternately.

16 are two intermittently-revolving disks provided with radially-sliding blocks 17, the lower ends setting in a cam-groove in a bedpiece, 19, whereby the blocks will recede to receive a nail in passing across the foot of passages 15, and again'close by contact with a cam, 18, to hold the nail firmly while being headed.

20 are two trip-hammers tilting 011 a bar, 21, and operated by wipers 22 on shaft 7, to strike a blow on the end of the nail protruding above blocks 17, to make a head on the nail when passing under the hammer.

23 is a ratchet-wheel on the spindle of disks 16,'and 24 are pawls engaging with the ratchetwheels, which pawls are connected by a bar, 25, pivoted thereto.

33 is a bar pivoted to bed 19 and bar 25, and said bar 33 is vibrated by a pitman, 26, con' nected byawrist-pin to a wheel, 27, on ashaft, 28, which is geared to a shaft, 29, by beveled cog-wheels, 30, and said shaft 29 is driven by pulley 31 and belt 6, passing over a pulley, 32, on main shaft 7 and pulley 5, whereby both ratchet-wheels will intermittently and alternately turn disks 16, and rest when the hammer is descending to head the nail.

The nails, after being headed, fall from the disks 16 through an aperture in the bed-piece into a receptacle below.

I claim as my inventi0n- 1. In a nail-cutting machine, the combination of the rotary cutter-head 2, the vibrating feed-table 9, chute 14, having passages 15, disks 16, having radially-sliding. blocks 17, trip-hammers 20, and means for intermittently rotating the disks, as set forth, for the purpose sliding blocks 17 to receive and grip the headdescribed. v less nails, and hammers 20, to head the nails,
