r IMPROVEMENT IN NAlLlNG-MACHlNE-S.
Specification forming part of Letters Patent No. 197,269, dated November 20, 1877 applicationfiled August 22, 1877.
To all whom it may concern:
Be it known that I, SAMUEL HARRIS, Jr., of East Oambrid e, in the county of Middlesex and Stateof assachusetts, have invented an Improvement in Nailing-Machines, of which the following is a specification My invention relates to an improvement in .machinesfor driving nails into the soles of boots and shoes.
Theinvention consists of a cylindrical hopper,- having upon its periphery a series of longitudinal slots or openings, of a sizesufficiently large to admit of the passage of the shanks of nails of a required size, the same beingheld by the enlargement at their heads until, by
.the rotation of the hopper, they are brought from each of the raceway-channels to a stationary slotted nail-guide, which acts, in con- .nection with the oscillating raceway, to place the nail in position to be driven.
By means of the double-channeled raceway I am enabled to drive twice the number of nails in a given time as could be driven by the use'of a single raceway, such as is commonly m y o The invention further consists in an adj ustable device for cuttingofi the pointed. ends of headed nails to any required length, at the will of the operator, for thepurpose of adapting themv to the varying thickness of material into which they are to be driven.
Referring .to the drawings, Figure l is afront elevation of a machine embodying my invention. Fig. 2 is a side view of the same. Fig. 3- is an enlarged view in detail-of the slotted nail-guide. Fig. 4 is an enlarged view in'detail of the double-channeled raceway and nailguide. Fig. 5 is a perspective view, showing the location and arrangement of the cutting contrivance with respect to the mouths of the double nail or tack raceways, a portion of the cover of said raceways being removed to facilitate the illustration. Fig. 6 is a side view of the nail-guide, with the weighted arms removed. Fig. 7 is a plan of the nail-guide, with the weighted arms removed; and Fig. 8 is a view of the front end of the double-channeled raceway, showing its pivot m.
a represents the head-frame, in which is mounted longitudinally the shaft b. On the front end of the shaft 12 is a cam, c, which serves to elevate the driver-bar against the stress of a spring, which forces the driver-bar downward when released by the cam. On the forward portion of the shaft bis a gear-wheel, f, which engages with a gear, g, attached to the back of a disk, h, which has a cam-groove on its face. A roll working in this cam-groove is attached to the upper end of a lever-arm, i, which vibrates on a center, 7:, in the frame a. The lower end of the lever-arm i is attached, by means of an adjustable block, c", moving in a yoke thereon, to the end of a reciprocating bar, 1, upon which is placed an adjustable block, m, to which is pivoted the forward end of the double-channeled raceway n.
O is a hopper, into which the nails are thrown, and it consists of a cylindrical cage, provided with longitudinal openings sufficiently large to allow the shanks of the nails and headless nails to drop through, but not large enough to admit of the heads passing through, so that as the hopper rotates the nails are carried up by their heads, the shanks projecting through the openings, and when brought to a position over the raceway they vdrop upon the same and adapt themselves to the channels of the raceway, the headless nails and the dirt, &c., passing out through the openings.
The raceway n is composed of two channels, 10 10, running parallel with each other, and both channels receive the nails from a supple mentary hopper, q, as they drop from the rotating hopper, and, as the raceway is caused to reciprocate while the machine is operated, double the quantity of nails will be supplied to the nail-tube in a given time than if only a single channel were used.
The rear end of the raceway it extends into the nail-hopper o, and is provided with a supplementary hopper, q, (shown in dotted lines, Fig. 2,) which serves to guide the nails into the channels in the raceway. The raceway n is also pivoted at p to the front bearing 10 of the hopper 0.
Over the raceway, inside of the hopper 0, and attached to its front bearing 0, is arranged a stationary shield, 1', consisting of a curved piece of sheet metal, which prevents the nails from falling upon that portion of the raceway, and also obviates the liability of the nails escaping through the front opening of the hopper.
The hopper o is rotated by means of a gear, 6, at its rear end engaging with a spur-wheel, t, on the shaft b, which latter may be driven by power applied to the pulley t.
In order 'to adapt the length of the nail to the varying thickness of a sole while it is being nailed, I have adopted a device for cut ting ofl the ends of the nails at the will of the operator during the operation of the machine.
This device consists of a bearing, 2, provided with the two notches or openings 2' 2', as shown in Fig. 5, to correspond with the ends of the channels in the raceway. The bearing 2 is supported upon the ends of arms u, one on each side of the lower part of the raceway, the said arms being pivoted, as shown at 3, Fig. 2. Fitted in the bearing 2 is a sliding bar, '0, provided with two notches or recesses. The solid portion between the recesses, as it passes to and fro in the recessed bearing 2, serves to cut off a nail-point passing into the recesses of the bearing 2. The arms which support the notched bearing 2 are elevated, so as to bring the slide or cutter '0 into action, by means of a pedal, 3;, in connection with the rod :10, bar or arm to, pivoted to the frame a, and operating the lever-arm u, fixed to the pivotal point 3 of arm u, as shown.
The sliding movement of the bar or cutter 1; is efiected by means of the ends of the same coming in contact with pendent bars 0 attached, one at each side of the frame, as the bearing 2 is moved to and fro with the raceway.
The length to be cut from the end of the nail is regulated by the degree of motion of the pivoted bar 10, the limit of which is adjusted by the stop w.
The nails are revented from riding out of the channels of e raceway by means of a strip of metal, n, placed over the top of the raceway, as seen in Figs. 2 and 4.
In Fig. 3, 5 5 are two jaws, having each a groove on its inner face, so as when closed together to form a tubular passage, constituting a continuation of the nail-tube 9, and serving to hold and guide the nail to be driven into the sole.
The jaws 5 5 form part of arms 6 6, which are pivoted at 7 7, and are caused to close togetherby weights88,acting as counter-weights. a is the feed, attached to the lower central part of a stirrup-frame b, on the end of a bar or rod, 0, connected to a cam, d, on the shaft b.
The bar 0 has a slot through its face, through which a pin or projection on the frame passes, and on which it oscillates, so as to impart the proper motion to the feed a.
The double-raceway channels 10 10 terminate in two diverging channels, 11 11, as shown in Figs. 4 and 5. The ends of the diverging channels 11 11 project over the ends of the slots 2 z in the stationary nail-guide 2, as shown in Fig. 4. At the point where the two angular slots of the guideway meet is the nail-tube 9.
At the rear of the nail-tube and nail-guide is the angular piece or block 12, the extreme points or angles of which serve to catch the shank of the nail from each channel 11 11 as the raceway reciprocates, the motion of the raceway causing the nail to be moved and guided directly to the nail-tube 9, thus insuring the positive delivery of the nail from the raceway to the nail-tube or driveway, to be acted upon by the driver.
Two fingers, n n", projecting one on each side of the end of the movable raceway, and playing into slots 13 13, (lshown enlarged in Fig. 3,) serve to prevent t e pointed ends of the nails from being thrown out of proper position.
Should the point of the nail, while passing through the nail-tube, be diverted from a straight course, the front angular walls of the slots in the nail-guide will prevent the point from being carried outward, and, as the nail descends, the countersink in the lower portion of the stationary nail-guide (shown in dotted lines 14 14, Fig. 3) will direct the point of the nail into the nail-tube.
I do not claim a slotted nail-hopper; but
What I claim as my invention is- 1. In a nailing-machine, the combination, with a rotating hopper having a series of longitudinal openings, of an automatically-vibratin graceway, pivoted outside of said hopper and composed of two parallel channels, one end of said raceway projecting within said hopper, and the other being provided with diverging channels, the several parts being arranged to operate substantially as and for the purposes set forth.
2. The vibrating double-channeled raceway, pivoted at a point exterior to the main hopper, and provided with the diverging channels 11 11, in combination with the slotted stationary nail-guide z, substantially as shown and described.
3. The combination of the slotted nail-guide z, the nail-tube 9, the angular block 12, and the diverging channels 11 11, as and for the purpose specified.
4. The fingers n a projecting from the end of the reciprocating racewa; at each side In testimonywhereof I have signed my name thereof, and adaptedto playin the slots 13 13, to this specification in the presence of two subas5ani1I1 for thel iilrpose set forth. d scribing witnesses.
