SPECIFICATION forming part of Letters Patent No. 472,638, dated April 12, 1892.

Application led August 22, 1891. Serial No. 403,461. (No model.)

To all whom t may concern:

Be it known that I, JOHN HYSLOP, Jr., a citizen of the United States, residing at Abington, in the county of Plymouth and State of Massachusetts, have invented certain improvements in nail selecting or separating devices for nailing and other machines requiring the selection of one or more nails at a time from a mass or quantity, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a side elevation of a portion of the head of a nailing-machine having my improved nail selecting or separating device apw plied thereto. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a similar section with the parts in the positions which they occupy after the selected nail or nails have been separated from the others in the line or row. Fig. 4: is a similar section showing the positions of theparts afterthe selected and separated nail or nails have been pushed intov the nail-channel. Fig. 5 is a vertical section on the line 5 5 of Fig. l. Fig. 6 is a horizontal section on the line 6 6 of Fig. l enlarged. Figs. 7 and 8 are perspective views of the front and rear sides of the plate which forms one portion of the nail-selecting device. In nail selecting or separating devices as heretofore constructed considerable difficulty has been experienced in separating the end nail or nails from the others in the raceway or track, especially when long nails having small heads were employed, as the points of the nails frequently crossed each other or became entangled, rendering it exceedingly difcult to separate them with any degree of certainty. When a picker was used,it would frequently be prevented from passing between the nails by this crossing of their points, which resulted in sometimes separating two nails at a time and at other times none at all. The same difficulties have been encountered when a revolving carrying-cylinder was used or when the track or raceway was moved sidewise, and in either case, unless the nails hung vertically in the raceway, the machine was liable to become obstructed and the nail would not be taken, or two nails would be taken when only one was required.

My invention has for its object to overcome these difficulties and to provide a simple, effective, and positive nail selecting or separating device which is especially adapted for nailing, pegging, or other machines where loose nails or pegs are employed; and to this end my invention consists in certain combinations of parts and details of construction,as hereinafter sot forth, and specitically claimed.

In the said drawings, which represent my improvements as applied to a nailing-machine, A represents a portion of the head of the machine, having, as usual, a nail-channel h, within which fits the nail-driver c, secured to the driver-bar B, the latter operated in a well-known manner by mechanism (not shown) connected with the main or driving shaft C.

The nails are conducted to the point where they are to be used-in the present instance the nail-channel of a nailing-machine--by means of a nail selecting or separating device consisting of an inclined track or raceway, into the upper end of the stationary part D of which the nails are fed in any suitable or well-known manner, the heads of the nails resting 4upon and being supported by the edges of the raceway, as seen in Figs. 2, 3, and 4c. The part D is provided with a cap or cover a, which is formed and screwed down thereon in such manner as to leave a space `between it and the edge of the raceway to permit of the free passage of the nails as they slide down and at the same time prevent them from being displaced or thrown out by any jar or concussion to which they may be subjected. The lower part of the track or raceway consists of a plate or block E, having a vertical movement with relation to the part D, the edges g of said plate tting and sliding within vertical ways or grooves h in the head A, and said plate abutting closely against the lower end of the part D and forming a longitudinal continuation or extension thereof.

The plate E is cut away at the center, forming an aperture o' from which to the lower edge it is also cut away, leaving a vertical roc :opening j for the reception of the ends or portions 1G 1G of two plates ts, the rear portions of which lie flat against the plate E and are secured thereto by nuts and bolts 12 13, the latter passing through slots Z in the plate E, whereby a lateral adjustment of the plates k r., which are supported by and slide on suitable guides, may be effected to vary the width of the central vertical space or throat 'm between them, through which the nails pass to the nail-channel b in a manner to be hereinafter described, said space being made adjustable in width by moving the plates 7U' 7i: to accommodate nails of dillereut sizes. For a similar purpose the two inclined bars which form the stationary part D of the raceway are made adjustable toward and from each other by means of screws 30 to vary the width of the space between them through which the nails pass to the space ym. The upper ends of the portions 10 of the plates 7u which lie within the openingj of the plate E, are made slightly concave and are on a level with the end of the main portion D ot the raceway or track, forming a longitudinal continuation or extension thereof, so that each nail as it slides down to the bottom of the said portion l) will pass into the vertical space m, with its head resting on the concave ends of the portions 10 of the plates k k. The shank of the nail as it enters the space m comes into contact with the upper end 1G of a narrow plate G, which lies within said space and forms a stop for the nail, as seen in Figs. 2 and The plate G is secured to the stationary part D of the track by means of screws q and slots fr, whereby it is made adjustable horizontally to vary the position of the stop 16 within the space m, in order to allow one or more nails at a time to enter the said space.

lVhen in the position seen in Figs. n and 3, the stop 1G will admit a single nail only, the head of which lies immediately under the block s, itting within the aperture t', but by moving the stop-plate G to the left two or more nails will be allowed to pass from the part D into the spacem, the last one just clearing the end of the part D of the track.

The plate E or vertically-movable portion of the raceway is raised to separate the nail or nails which have been allowed to pass into the space m from those in the part D of the raceway by means of a cam Il on the drivingshaft C, which acts upon the horizontal arm 17 ot' a bar t, slidingin a suitable bearing, and secured at its lower end by means of a setscrew u to an arm 18, Fig. 5, theinner end of which is bifurcated and embraces a lug o, projecting from one side of the plate E, a spiral spring w returningr the parts to their normal positions as soon as the cam H has ceased to act on the arm 17. After the sc- One device or mechanism will now be described; but other devices may be employed in accordance with the nature ot' the machine to which my improved selecting or separating device is applied.

As the plate E rises, the nail is carried up above the stop-plate G into a position opposite to the end ot a pusher-lever a', fulcrumed at 20, the lower portion ot which consists of a thin blade or plate 2l,adapted to enter the space m and push the nail or nails therethrough into the nail-channel b, ready to be acted upon bythe nail-driver in the usual manner. The lever d is actuated at the proper times to el't'ect the delivery of the nail or nails into the nailchannel by an inclined rod b', pivotcd thereto, and connected at its upper end with a lever c, fulerumed at d and carrying at its upper end an anti-friction roll e', fitting within the groovef of a camwheel L on the driving-shaft. The lever c is secured to the rod b by screw-nuts g at the outer end of said rod, and between a collar 25 and the end ot' the lever c the rod b is encircled by a stift' spiral spring 7L', which permits the lever c to yield or slide over the end of the rod b in case of any obstruction, which might prevent the movement of the said lever, thus avoiding any breakage or injury ofthe parts as might otherwise occur. The thin portion of the plate 21 ot` the lever a is made removable, so that another can be substituted therefor corresponding to the width ot' the space m, which, as before stated, can be varied for nails of diierent sizes or shapes. As soon as the nail has been pushed into the nail-channel the plate 21 of the pusher a is withdrawn from the space m, when the movable portion E of the raceway descends to its original position to receive another nail or nails, when the operation continues as bcfore.

The above-dcscribed nail-selecting device composed of two separate parts, one of which is movable vertically with respect to the other, is simple,durable, perfectly reliable in its action, and not liable to get out of order, and will be found to be equallyeiective with nails of all sizes and shapes, which is a very important consideration in devices ot this character.
