SPECIFICATION forming part of Letters Patent No. 595,878, dated December 21, 1897.

Application filed August 5, 1897. Serial No. 647,168. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM GODDU, residing in Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Nailing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to a nailing-machine and is herein shown as embodied in a machine adapted to be operated by hand and technically known as a hand-tacker.

In accordance with this invention the machine is provided with a holder or receptacle for the tacks or nails, which is movable with the driver-bar, so as to agitate the nails or tacks and thus supply the same to the roadway, from which the tacks or nails are delivered one by one to a nail-delivering passage preferably made in what may be termed the body or stationary portion of the machine and which communicates with a pass sage for the driver. The nail-delivering passage communicates .at its lower end with the driver-passage for the delivery of the nails or tacks into the said driver-passage, and at its upper end it is adapted to communicate with the slot or passage in the roadway when the latter is in what may be termed its lowered position, in which position the endmost nail in the roadway is transferred to the naildelivering passage by a separator, as will be described. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation, with parts broken away, of a nailin -machine embodying this invention; Fig. 2, a front elevation of the machine shown in Fig. 1; Fig. 3, a vertical longitudinal section of the machine shown in Fig. 1, with the driver-bar elevated; and Fig. 4, a front elevation of the machine with the parts in the position they occupy when the driver-bar is elevated, as shown in Fig. 4.

In the present instance I have illustrated my invention as embodied in a hand tool or machine comprising a body portion A, which is adapted to be grasped by the hand of the operator and held stationary against the work--suoh, for instance, as the upper of a boot or shoeand a movable head or upper portion A, which may be provided, as shown, with a handle a. The body portion A is preferably made in two parts a a secured together, as by screws a and having formed in them a slot a for the reception of a driverbar a, a passage a for the reception of a driver a secured to the driver-bar, as by a screw a and preferably a nail or tack delivering slot or passage a, Which communicates clined or curved top 12 and sides 6 b the side b being preferably made movable, so as to uncover the said receptacle or holder, and in the present instancethe said side is represented as pivoted at b and provided with hook or latch b, which is adapted to engage a pin 19 to secure the cover or movable side I) in its closed position.

The movable head A is cored or otherwise formed to receive a roadway b for the nails, which is extended into the holder or receptacle b and is provided with a suitable slot or nail-passage 19 down which the nails or tacks Z9 descend. The slot b in the roadway may be enlarged at its rear end, as at 3, for the ready reception of the tacks or nails, which are retained in said slot by the head A and a retaining strip, piece, or guard 17. The roadway at its lower or delivery end is formed so as to leave a passage for a knife or blade 0, attached to a lever c and constituting a separator or transferrer by which the endmost nail in the roadway is transferred into the passage 0. when the driver a is in its lowered position. The lever c, as shown, is pivoted to the head A at c and is moved in one direction by a spring 0 having one end secured to the head and its other end to the separator-lever c, the said spring acting to keep the lever c in engagement with a cam-surface c on the side of the upright or extension at so that the said lever may follow the path or shape of the cam and move so as to cover and uncover the slot in the roadway at the proper time.

In Fig. 1 the parts are in the position they occupywhen a nail or tack has been driven, the movable head and its attached driver-bar and driver having been moved by the operal tor down toward the body portion A, which may be supposed to have its nose d pressed against the work. A nail or tack havingbeen driven into the work, the head A is lifted by the operator into substantially the position represented in Figs. 3 and 4. movement or stroke of the head and its attached parts the driver a is lifted, so as to On the upward uncover the discharge end of the naildelivering slot or passage a", which permits a nail I therein to drop into the driver-passage a in the nose. rator knife orblade c is moved outward by As the head is moved up the sepathe cam 0 so as to uncover the slot in the:

The tool or machine is now in condition to drive the nail in the driver-passage, which is efiected by the operator moving the head A toward the body A and from the position shown in Figs. 3 and at to that shown in Figs.

l and 2.

On the dow nstroke of the head an 3 driver the separator-blade is moved inward? by its spring 0 keeping its lever c in engagement with the cam 0 and the said separatorblade passes behind the endmost nail in the j roadway, and when the slot in the road-way is i brought in line with the inlet mouth or .endj

of the nail-passage a the separator-bladewill 1 at such time transfer the endmost nail into said passage and at the same time close the 1 slot in the roadway.

The nail or tack delivered into the passage a on the downstroke of the driver will desoend into the driver-passage a on the next upstroke of the said driver. The nails or tacks in the receptacle are agitated bythe movement of the said receptacle with the driver and drop into the slot in the roadway, and on the downstroke of the driver the nails or tacks in the receptacle will fly up and strike the rearwardly curved or inclined front upper portion 2 of the receptacle and be directed down over the enlargement 3 in the roadway, so that the latter may be kept full of nails.

In practice the body portion A of the tool is moved over the work between thedownstrokes of the driver, and ordinarily the driver a will close the month of the passage 0. while the position of the tool with relation to the work is being changed; but to prevent the tack or nail in the passage a dropping into the driver-passage a and then out therefrom by the operator moving the driver into its upper position (shown in Fig. 3) while the tool is lifted off from the work in the act of bringing its nose into a new position-that is, into engagement with another portion of the work--I have provided means for closing the said driver-passage, which is automatically removed by the nail or tack when the latter is driven. The means referred to may be a substantially light strip of spring metal f, (see Fig. 3,) which is secured in a slot f in the body portion at one end by a screw j and has its free or lower end normally extended across or. into the driver-passage a, as represented in Fig. 3, a sufficient distance to practically close the said passage at its bottom, but which spring yields to the tack or nail as the latter is forced out of the passage a by the driver.

I claim- 1. In a nailing-machine, the combination with a body portion provided with a driverpassage and with a nail-delivering passage communicating with said driver-passage, of a movable head carrying a nail-receptacle, a roadway, a separator, and adriver, and a cam on said body portion to operate said separator, substantially as described.
