IMPROVEMENT IN NAIL ASSORTING AND FEEDING MACHINES.

Specification forming part of Letters PstentNo. 135,312, dated January 28, 1873 reissue No. 1,648, dated March 6, 1877 application filed February 9, 1877.

To all whom it may concern.-

Be it known that I, Bnwmm BEVELAN- DEB, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Nail Assorting and Feeding Machines, which are fully described in the following specification, and delineated in the accompanying drawings.

The invention relates particularly to the construction and organization of a mechanism inclined bottom, and containing a verticallyreciprocating lifter, having an inclined top ischarge a blank into a chute down which it moves until it reaches a stop. Passing this stop the blank approaches and moves under a gage, provided the blank is right face up; but it it rests upon its edge or its head-projecting face, the gage will stop it. After the blank passes the gage it meets a directing device, which operates to turn the blank so that its head thereafter leads in the further movement of the blank down the chute. The invention shows a slidebar to right the blank should it arrive at the gage in any other position except with the straight or flat face of the nail against the chute, and also a blank-starter to act against the head of a blank not properly tipped and discharged from the directing device.

This invention consists, primarily, in an organization of mechanism to automatically separate or select horseshoe-nail blanks, and present them one by one, head first and right face up, to a rolling-machine, or other mechanism for an equivalent purpose.

Figure 1 represents, in side elevation, a machine embodying my invention; Fig. 2, a sec,-

tional elevation, and Fig. 3 a plan thereof; I

extending inward toward the front walla, I

which is vertical. Extending up into the bottom of the hopper against the wall c,and'form- 7,

ing part of such bottom when at its lowest position, is a vertically-moving slide, d, jointed by a link or lever, e, to a cross-rod, f, said link being raised and lowered to reciprocate the slide in suitable guides by a crank on a driving-shaft, h. The slide has an inclined top-or face, 0', which, when the lifter is at its highest position, stands just back of the mouth of a compartment or chamber, k. Horse-nail blanks supplied within the hopper b, and above the upper end or face of slide (1, will be raised, one or more at a time, by the slide, and when the face i is at its highestposition such blank or blanks will pass therefrom into the chamber 70. To agitate and insurethe lodgment of one 'or more blanks upon the lifter d, a second slide, l, may be located just back of the slide d. The slide 1 is raised by a pin, m, extended from the lifter d, which meets it, when the lifter rises some distance, and it falls by gravityor by the stress of a suitable spring when the slide descends. slide-l is preferably elevated after the slide d has partially risen, and in descending it reaches its lowest position before the lifter d arrives at the bottom of the hopper. The top face of slide 1 is inclined to meet the face 1' of the slide d, such inclination and the. movemeat of the agitator-slide I almost always insuring the lodgment of one or more blanks upon the lifter. The bottom of the chamber 70 is also inclined, and its front portion is formed by the top surface of lifter n, upon which but one blank will generally lodge. This lifter may be raised by the link 0, which meets its bottom, and may descend by gravity, or by the stress of a suitable spring. When elevated its face j is brought into position to permit the blank lodged upon it to slide for ward by gravity onto a downwardly-inclined The,

side up, the gage-plate will detain it.

chute, 0. When the blank slides over upon the chute it lodges against two pins, where it' stops until the blank in advance pf it has been discharged. These pins extend from a rod, q, passing through guide-slots inthe chute, areheld up by a suitable spring, '1', and drawn down by an arm, a, which, extended from the rod, is struck by the lifter a when it descends, the lowering of the pins leaving the blank free to slide down the chute.

If the blank placed in the chute, 'asdescribed,

rests with its flat side against the bottom of the chute, or right face up, it will descend in the chute, passing under the gage-plate e, the space between the lower edge'ogsuch gageplate and the chute-bottom bein that the head thereafter leads or remains in advance of the point as the blank continues its descent to the rolling-machine, or to other device to receive it.

The narrowing side flanges "v assist in'ree taining the blank in position-head first. The blank is discharged at the opening vw. If the blank, as it strikes the directing device 14, does not tip sufficiently to cause it to slide down therefrom, I may start or dislodge it bymeans of a blank starter, an, extended across the chute.

This blank-starter is composed. of a bar, having its ends fitted in irregular guide-slots g. It is drawn downward by a link, 2, jointed to a lever, on, pivoted at b, and a cam, c, on the driving-shaft, and it is elevated by a spring, d. When the blank-starter rests in the highest portion of the guide-slots it cannot strike the blank; but as the starter is moved down, it will strike the head of a blank, provided there should be a blank-in the chute which was not tipped sufliciently byv the directing-bar to move past it down the chute, and will start such blank down the chute head first. If the blank placed in the chute at top has its flat or wrong To right the blank, a slide-plate, f, slides up underthe gage-plate after each descent of the pins 1), that let the blank down the chute. This slide is raised by a cam, h, that strikes a lever, which presses against the slide, a spring, k, drawing it down when the cam it passes the lever. As the front or upper edge of the slide advances against the blank it overturns the blank, and brings it upon its flat side, when it will slip under the gage-plate of ashape' to permit its passage when the flat side of the nail rests against the chute-bottom. The ont-' a mus.

.nd slide down to the directing device. The plate 9' is formed as a spring, its front end vbeing made thin or brought to an edge, so that when pressed down its surfacewill be nearly flus'h with the chute-surface above it, its spring permitting it to rise for the slide to pass under it, the plate springing down when the slide moves back: By these means the" blanksare selected or separated, and delivered one-by one, head foremost and right'face up.

- By referring to Fig. 4, it will be noticed that the passage between the lower face of the gage eand the chute on which the blank rests is,'from' each toward the other on d,of a shape corresponding in longitudinal section with an ordinary horse -nail blank. This opening,

.shaped as shown, will permit the passage of blanks that rest with their flat faces upon the chute, thehead portions in such case. projecting laterally from one face of the blank, (hereindenominated the right face,) projecting upward,the-uppermost face of the blank in such case conforming in shape with the opening below the gage. e r v v The upper faces of the slide-bar and lifter are substantially horizontal from end to end, to lift the blanks at head and point evenly, to place them on the chute, and are beveled from edge to edge, to permit the blanks to fall therefrom by gravity.

The specific devices and the details of construction and arrangement may, of course, be varied without departure from the essence of the invention.

I claim--. a
