TACK OR NAIL HAMMER.

SPECIFICATION forming part of Letters Patent No. 609,672, dated August 23, 1898.

Application filed May 25, 1897. Serial No. 638,139. (No model.)

To all whom it may concern:

Be it known that I, GEORGE ERNEST HAS- ZINGER, of Vicksburg, in the county of Warren and State of Mississippi, have invented certain new and useful Improvements in Tack or Nail Hammers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hammers having an automatically-operating tack-feeding attachment; and it consists of the details of construction and arrangement, which will be more fully hereinafter described and claimed.

The object of the present invention is to provide convenient means in connection with a hammer-head for readily setting a tack in position for driving by a simple mechanism operated from the handle of the hammer, the several parts being strong and durable and easily and readily applied and comparatively inexpensive in the costof manufacture.

In the accompanying drawings, Figure 1 is a perspective view of a hammer embodying the invention and showing a loading-fork at one side adapted to be used with the device, all of which embody the features of the invention. Fig. 2 is a side elevation of the hammer embodying the invention and broken away at parts to show the interior construction. Fig. 3 is a detail perspective view of the feeder attachment and its operating parts disconnected. Fig. 4 is an enlarged sectional perspective view of the end of the hammer, showing the feeding attachment in connection therewith and slightly turned to one side. Fig. 5 is a detail perspective View of a portion of the feeder and the retaining springfinger coacting therewith. Fig. 6 is a detail perspective View of the rear end of the hammer-handle broken away to show the interior construction. Fig. 7 is a detail perspective view of a slightly-modified form of the feeder, showing a spring-clamp in connection'with the cap on the foot thereof. Fig. 8 is a detail view showing the pivotal or hinged connection of one of the parts.

Referring to the drawings, wherein similar numerals of reference are employed to in dicate corresponding parts in the several views, the numeral 1 designatesa handle which is hollow and open at one side, as at 2, and provided with a suitable form of head 3, with an opening4 extending from one side to the other in line with the upper portion of the handle, and a lower circular opening 5 adjacent to the impacting end of the hammer. Pivotally applied to the handle 1 is a wire lever 6, having a rearwardly-extended inclined pressure end 7 and a depending arm 8, which has the rear end of an operating-rod 9 movably attached thereto. The said rod 9 passes through a guide 10 on the lower side of the handle and is encircled by a coiled spring 11, which bears against the said guide at one end and is attached to the said rod 9 at the opposite end. The outer end of the said rod 9 is formed into a loop and bent at a right angle, as at 12.

Extending through the circular opening 5 in the head of the hammer is a rotatable spindle 13, which has a twisted flattened screw 14, engaged by the angular bent loop 12 of the operating-rod 9, and to hold the said spindle in proper position in the opening 5 a pin 15 passes transversely therethrough at a slight angle of inclination to allow the said spindle to have a sliding movement. Continuous with or attached to the outer end of the spindle is a feeder 16, having at the foot thereof a recess 17, which opens out at one side, as at 18, and is covered by a cap 19, held in position by suitable rivets or other fastenings. Within the said recess 17 is pivotally mounted a small retention-plate 19, having a spring 20 connected to a projecting car 21 thereof, beyond the pivotal point of the same, and tending to throw the said retention-plate downwardly or toward the bottom of the recess 17 The said retention plate is bifurcated or recessed and has projecting from one side thereof a finger 22, arranged at an angle of inclination and projecting slightly through the opening 18 of the recess 17 Extending outwardly through the open portion 2 of the handle 1 is a flanged channel- 1 plate 23, which is arranged at an angleof inclination and extends in a downward plane from the inner side of the opening 4 through the handle and toward the opposite "side from that through which it extends and for a distance runs longitudinally with the rear part of the handle, being inclosed at its rear end,

and is engaged by a retention spring-finger 24, having an angular bend 25 to hold the tacks in the channel-plate when the latter is locked. The, rear end of the said channel-plate within the handle is flared, for a purpose which will be presently set forth.

As shown by Fig. 1, a loading-fork 26 is adapted to be used with the handle 1 and consists of an elongated tube having a slot 27 extending longitudinally through one side thereof. The one end of the said loadingfork is cut off at an angle of inclination, as at 28, and forms upper lips 29, which are pointed and have a flared mouth 30 between the same. These pointed lips 29 and flared mouth are inserted in the end of the hammerhandle and engage the rear flared portion of the channel-plate 23, and in this operation the retention-spring 24 ispressed back, so that the tacks carried by the loading-fork may freely slide into the said channel-plate. The opposite end of the loading-fork is bent upwardly and provided with tack-pulling toes 31, a cross-pin 32 being mounted in the upper portion of the loading-fork adjacent to the toes 31 to prevent the tacks from slipping out of the channel 27 at this point. In loading the fork the same is plunged-into a receptacle containing a quantity of tacks and the latter enter through the flared mouth 30 and automatically position themselves in the channel 27 with the heads thereof on the outer side and the points depending toward the interior of said fork. The cut-away portion 28 of the fork facilitates the unobstructed entrance of the tacks into the channel 27 and permits the lips 29 to be penetrated a considerable distance into a bed or quantity of tacks.

It will be seen that the tacks are delivered from the loading-fork to the channel-plate 23 with the points downwardly and the heads above, as previously set forth, and by this means the heads are fed into the rear portion of the said channel-plate, so that the points of the tacks will extend in a direction nearest the operator when the hammer is held in operative position. By having the channelplate 23 arranged at an angle and extending from one side of the outer portion of the handle to theinner part of the opposite side of said handle afree and uninterrupted feeding movementof the tacks through the channel-plate is obtained and a greater number of tacks can be loaded into said channel-plate in view of the increased length through the inclined arrangement. Furthermore, this arrangement also properly positions the tacks at their point of delivery to the feeder. At the said delivery end of the feeder is a catch-spring 33, consisting of a small spring-wire attached along the upper portion of one side of the said channel plate and extending diagonally through the'openin g 4 in the hammer-head 3 and over the upper portion of the channelplate at this-point, and at its outer end the said catch-spring has a transversely-extending finger 34, which is continuous, with an arm 35 arranged at a right angle thereto and formed by rebending the wire at this point. The finger 34: normally lies across the top of the channel-plate and holds the tacks in position therein against accidental disengagement while the feeder 16 is operating to set a tack in position or after said feeder has received one tack from the outer end of the said channel-plate. The said channel-plate is also formed with a projection 36, over which the arm 35 has play, and said projection is engaged by the finger 22 to raise the retention-plate in the recess of the feeder to permit a tack-head to pass thereunder, when the feeder is returned and its recess alines with the outer end of the channel-plate 23. When the said feeder has its recessed end moved into alinement with the channel-plate 23, one side thereof strikes the arm 35 and presses it back, so as to clear the finger 34 from the channel-plate and permit a tackhead to fall into the said recess of the feeder, and the moment the said feeder is moved away from contact with the arm 35 the finger 34: and the said arm move across the top of the channel-plate and hold the tacks in the latter against movement until the feeder again returns to receive another tack. At the same time the retention-plate in the recess 17 of the finger clamps the tack in position, and to accommodate the movement of the tack without friction a recess 37 is formed in the head of the hammer and hasa slightlycurved contour. The said hammerhead is also formed with the further recess 38 on the opposite side, which receives the outer end of the spring-wire having the finger 34 and arm 35 thereon when moved laterally. The cap 19 is also formed with a recess 39, through which the shank of the tack projects, and when the feeder is thrown entirely around to place the tack in position its end is located in advance of the impacting end of the hammer-head.

To compensate for the difference in the size of tacks, a regulator is provided for the feeder 16, and consists of a pin 40, which is adjustably mounted in the said feeder 16 and-is engaged by a set-screw 4.1. This pin regulates the distance the feeder stands out from the hammer-head when closed in thereover by throwing the foot outward or drawing it in relatively to the channel-plate 23. This adjustment is permitted through the slight movement of the spindle 13 in the hammerhead, and in the latter a socket 41 is formed, into which the inner end of said pin 40 falls to prevent a rebound of the feeder. To limit the outward movement of the feeder, the 11ammer-head is provided with a shoulder 41 against which the feeder strikes when thrown outwardly.

In Fig. 7 a spring-clamp 42 is applied to the cap 19 of the feeder and is adapted for use in putting up bill-posters and to hold a sign at an elevation and at the same time start the tack thereover through the medium of the feeder. The handle 1 at its front portion adjacent to the head 3 is supplied with a wood filling 43 to strengthen the handle at this point to provide a firm connection for the head of the hammer. The angularly-bent loop 12 of the rod 9 travels backward and forward over the screw on the shank 13 and operates in one direction to throw the feeder around over the impacting end of the hammer-head and in the opposite direction to close the said feeder inwardly in line with the channel-plate 23.

A further advantage in the arrangement of the channel-plate as set forth is that in the act of striking or delivering a blow the tacks slip more readily to the feeder by dragging on either side of the slot or on either side of the shanks of the tacks than they'would do if the channel-plate were turned over. The latter arrangement would have a tendency to cause the heads of the tacks to jam against the top and bottom of the channel-plate While sliding on their heads.

It will also be seen that the. feeder 16 has two movements. It first moves forward and then turns around, said forward movement being necessary to overcome in part a rebound on the return stroke.

It will be understood that the handle of the hammer is preferably made of sheet metal, with the joint thereof on top, so that the channel-plate can be put in place before clos ing the'hammer-handle, also that the form of the channel-plate may be changed, if desired.

The device as an entirety is exceptionally convenient for many uses where tacking or fastening devices are necessary.

It will be understood that the dimensions of the device may be varied at will and that many minor changes in the details of construction and arrangement of the several parts'might be made and substituted for those shown and described without in the least departing from the nature or spirit of the invention.
