f IMPROVEMENT IN NAIL-FEEDING MACHINES.

' l Specification forming 'part of Letters Patent No. 181,376, dated August 22, 1876; `application led Mayaa, 181e.

To 'all whom it may concern Be it known that I, FRANK ToEPFER, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented an Improvement in Nail-Feeding Machines, of which the following is a specification The invention consists of a descending trough, in which the nails hang by the heads, points downward, arranged so as to drop the nails horizontally into a hopper in advance of the sliding driver, on which trough are a couple of blades, arranged side by side, with space for one nail between them, which are so geared to the driver that when it goes forward to drive the nail in advance of ,it the upper blade draws back, and the lower one goes forward to receive the lowest nail in the trough against it', and when the driver goes back the are nails to be driven into one side ofthe box to be nailed, and the drivers will be adjustably connected for shifting toward and from each other, according as the lnails are to be driven more or less distant from each other.

Figure l is a longitudinal sectional elevation `of the machine, in line x w, Fig. 2. Fig. 2 is a plan view, and Figs. 3 and 4 are details.

Similar letters of reference indicate corresponding parts.

A represents the trough, in which the nails hang side by side by the heads, and'slide down into the hopper B in advance of the driver G, being delivered one by one by the blades D and E, the blade D being pushed forward by the driver-stock F, which goes back between the nail lying, against blade E and those above it, and the blade E being driven back at the lmoment the driver arrives at the limit of the back stroke, to let the nail fall down into the hopper B, in front of the driver.

At the forward movement of the driver, the blade E is again pushed forward to arrest the nails', which are thenl let down against it by the withdrawal of the blade D.

The blade E is connected to the driver-stock by the slotted link G and studpin H, lso that it rests while the driver stock is moving through the greater part of its travel, but afterward moves in the same direction, while the blade D is connected by the lever J and said link G, so that it movesin the reverse direction.

The trough terminates at the lower end in a slanting tube, K, onto thelower side of which the nails drop, so as to slide out at the lower end, and drop sidewise into the hopper, with the head next to the driver, said tube being suitably located above the hopper for that purpose.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- A l. The combination of the reversely-slidin g cut-off plates E D with the feed-trough A, hoppose set forth.

FRANK TOEPFER.
