T 0 all whom it nmy conccm:

Be it known that I, Mnmu'ox E. PERRING, a citizen of the United States, residing at Marcellus, in the county of Cass and State of Michigan, have invented a new and useful Hammer, of which the following is a specification.

It is the object of this invention to pro vide a hammer so constructed that it may receive a plurality of nails, means being provided for segregating a nail and for advancing it into a position in which it may be set for driving.

Another object of the invent-ion is to provide a novel means for segregating a nail from the receiver.

Another object of the invention is to provide a novel means for advancing a nail in front of the anvil portion of the device, and for holding the nail in front of the anvil, to receive an initial blow whereby the nail may be mounted in the structure in which it is to be driven.

Another object of the invention is to provide a novel means for connecting the segregating mechanism with the mechanism for holding the nail in place in front of the anvil, and to provide a manually operable device of novel and improved construction, whereby both the segregating means and the means for holding the nail in position, may be manipulated.

The drawings show typical embodiments merely, and it is to be understood that changes, properly falling within the scope of what is claimed, may be made without departing from the spirit of the invention.

In the accompanying drawings,Figure 1 shows the invention in longitudinal section, parts being in elevation; Fig. 2 is a fragniental rear elevation of the receiver, showing the upper end thereof; Fig. 3 is a rear elevation of the slide; Fig. 4- is a top plan of the receiver extension, and of the mechanism which is carried thereby; Fig. 5 is a bottom plan of the striking end of the hammer head; Fig. 6 is an elevation of the end, or striking face of the hammer; Fig. 7 is an end elevation of the hammer handle; Fig. 8 is -a front elevation of the receiver, the receiver extension, and the operating mechanism which is connected therewith; parts being removed; Fig. 9 is a fragmental side elevation of the receiver and the receiver extension, together with the mechanism thereby carried, the view illustrating the opposite side of the receiver from that shown in Fig. 1;" Fig. 10 is a detail perspective of the end of the receiver extension; Fig. 11 is a transverse section upon the line AB of Fig. 1; Fig. 12 is a transverse section of the receiver, taken along the line C-D of Fig. l; and Fig. 13 is a fragmental longitudinal section of the receiver extension, designed to show the manner in which certain parts of the device cooperate to advance the nails in the receiver, toward the receiver extension.

The invent-ion includes a tubular handle 1, to which the head of the hammer is secured, the striking end 2 of the hammer head being tubular, and open in its interior, while the claw end 3 of the head is preferably, although not necessarily, of a solid construction; it being understood that the hammer handle and the head may be of one-piece construction, as shown, or the head and the handle may be assembled with each other in a manner not inconsistent with the operation of certain mechanisms to be described hereinafter.

The receiver in which the nails are held previous to driving, is preferably fashioned from a single piece of material, bent sharply upon itself along its longitudinal center, as denoted by the numeral 4 in Fig. 12, to form parallel side walls 5, the free edges of the walls 5 being concaved outwardly, to form a trough-shaped portion 6. The receiver, as thus constructed, is mounted in the tubular handle 1. As seen to best advantage in Fig. 1, a plurality of light, spring strips 7 are secured at one end to the hammer handle 1, and positioned to project into the trough-shaped portion 6 of the receiver. referring to Fig. 7, wherein the end of the hammer handle 1 is shown, it will be seen that the nails may be inserted through the end face of the hammer handle, the shanks of the nails sliding between the parallel side walls 5 of the receiver, the heads of the nails being located in the trough-shaped portion 6. The spring strips 7 are adapted to bear against the nails 9, as seen in Fig. 1, to prevent them from sliding downwardly out of the end of the hammer handle 1.

Projecting at right angles from the receiver, and located in the striking end 2 of the hammer, is a receiver extension 10. The bottom of the receiver extension 10 is open, and when a nail located in the handle of the l hammer, as seen in Fig. 1, is slid along the receiver, the nail will, when certain mechanisms to be described hereinafter, are manipulated, be free to pass into the receiver extension 10. Adjacent its ends, the receiver extension 10 is flattened as denoted by the numeral 11, thus defining a transverse shoulder 12 in the extension. The body portion of the nail is adapted to rest in the flattened portion 11 of the extension, while the head of the nail will be engaged by the shoulder, to prevent the nail from sliding out of the striking end 2 of the hammer. This construction is most clearly discernible in Fig. 10 of the drawings. The end face of the portion 2 of the hammer is denoted by the numeral 39, and by referring to Fig. 6 it will be seen that there is a slot 40 extended inwardly into the end face 39, the slot being alined with the flattened end 11 of the extension 10. By referring to Fig. 5 of the drawings, wherein the lower face of the end 2 of the hammer is shown, it will be seen that there is in the said lower face of the striking end of the hammer, a T shaped opening, the head 14; of which is alined with the shoulder 12, the rectangularly disposed portion 15 of the T shaped slot being alined with the flattened end 11 of the extension, and likewise alined with the slot 40 in the end face 39 of the hammer. Broadly speaking, the receiver-extension is a trough-shaped structure, and in the upper portion thereof is located an anvil 16. This anvil 16 terminates adj acent the shoulder 12 in the extension 10.

At this point I will describe the path followed by a nail in passing from the end of the hammer handle 1 into the protruding position in which the nail is shown in solid. lines in the upper portion of Fig. 1 of the drawings; and subsequently I will describe the mechanism whereby this nail is advanced and held in the position shown.

When the nail is inserted into the receiver at the lower end of the hammer handle 1, the shank of the nail will be disposed be tween the parallel side walls 5 of the receiver, the head of the nail being disposed in the trough-shaped portion 6 thereof. The several spring strips 7 serve to prevent the nails from sliding out of the receiver, through the end face of the handle 1. Presupposing that the hammer is inverted from the position shown in Fig. 1, it will be seen that the nails will slide downwardly in the receiver, ultimately passing into the receiver extension 10, and resting upon one face of the anvil 10. The nail is then free to slide longitudinally and it may be slid outwardly, toward the end face 39 of the hammer. As the nail thus moves toward the end face 39 of the hammer, the head of the nail will ultimately engage the shoulder 12, the shank of the nail dropping into the fiattened portion 11 of the receiver extension, the nail thus being positioned as shown in solid lines in the upper portion of Fig. l of the drawings.

Passing now to a detailed description of the means whereby a single nail may be segregated from the receiver and deposited in the receiver extension, it will be seen that a finger lever 17, protruding through an opening 19 in the handle 1, is pivoted at 18 to the side walls 5 of the receiver. Secured at one end to the side wall 5 of the receiver, is a spring strip 20, the free end of which is disposed adjacent the transverse head of the hammer. l ulcrumed upon the portion 5 of the receiver, and located beneath the free end of the spring strip 20, is an angularly formed lever 21, the pivotal mounting of which is denoted by the numeral 22. A connecting member 23, preferably a spring plate, unites the finger lever 17 with one arm of the lever 21. The specific connection between the spring plate 23 and the lever 17 is seen most clearly in Fig. 1. It will there be seen that in a lateral extension of the spring plate 23, there is an elongated slot 100, in which a pin 101, projecting from the finger lever 17, is adapted to move. The free end of the spring strip 20 is slidable in a finger 26 projecting from a slide 25, the slide 25 being held for movement transversely of the receiver and adjacent the receiver extension 10, in a suitable guide 2a. This slide, which is adapted to segregate one nail at a time from the receiver and to deposit the same in the receiver extension, is seen most clearly in Fig. 3 of the drawings. As there shown, the lower edge of the slide 25 is notched to form a tongue 27. This notching of the slide results in the formation of a straight edge 102, and in the formation of a relatively large opening 103 in the slide, the edge of the opening 103 serving to determine the tongue 27. The opening 103 is bridged over by a covering 28.

Projecting laterally from the receiver extension 10, are spaced bearings 29, in which is mounted a pivot pin 30. Upon this pivot pin is fulcrumed, intermediate its ends, a lever, the same including a spring arm 31 disposed upon one side of the pin 30, and a spring strip 32, disposed upon the other side of the said pin, the spring strip 32 being secured at one end to the spring 31, while both of the elements 31 and 32, at one end, are held for pivotal movement in the slide, or segregating member 25. The free end of the element 32 may be secured about the member 31 by means of a collar or the like. Adjacent its end, the spring arm 31 is bent, as denoted by the numeral 34, to form a head 35, disposed substantially at right angles to flattened portion 11 of the receiver extension 10. The upper edge of this head 35 is beveled as denoted by the numeral 36, and in the side walls of the flattened portion 11 of the extension, there 40 over the upper face of the one of the teeth 112.

6 toward the head of the hammer.

are openings 37 in which the head 35 is adapted to reciprocate, transversely of said extension. If desired, a stop 38 may be mounted upon the head 35, the stop being adapted to engage the portion 11 of the receiver extension, to prevent the head from moving too far into the opening 37.

Referring now to Fig. 9, wherein an opposite side of the device is shown, from that depicted in Fig. 1, it will be seen that a plate 104 is pivoted at 105 to the finger lever 17, the opposite end of the plate 104 being pivoted at 106 to a plate 107 adapted to slide upon the portion 5 of the receiver. In this sliding plate 107 there is an elongated slot 108 whereby the sliding plate 107 is adapted to move longitudinally upon a pin 109, protruding from the receiver extension into the slot 108. Secured to the end of the sliding plate 107 is a spring arm 110, adapted to reciprocate in a guide 111 secured to the portions 5 and 6 of the receiver. Adjacent its free end, the spring arm 110 is provided, as seen most clearly in Fig. 13, with spaced teeth 112; these teeth are adapted to pro trude through a slot llt in the receiver, as seen in Fig. 2. Outstanding laterally from the spring arm 110 is a stud 115. A spring plate 116 is secured at 117 to the portion 5 0'of the receiver, the end 118 of the spring plate being bent downwardly into contact with the portion 5 of the receiver. The spring plate 116 is notched to form a laterally projecting portion denoted by the numeral 119 in Fig. 9. Then the spring arm 110 is moved longitudinally, the stud 115 will pass beneath the laterally projecting portion 119 of the spring plate 116, engage the curved end 118 of the spring plate, ride spring plate, and drop from the laterally projecting portion 119, into the position shown in Fig. 9 of the drawings.

The operation of the device is as follows.

4 Presupposing that the hammer is inverted from the position shown in Fig. 1, it will be seen that the nail 9 will slide downwardly in the receiver, between the side walls 5 thereof, until the line of nails rest against If the free end of the finger lever 17 be then moved in the direction of the arrow B in Fig. 1, the pin 101 in the lever 17 will move in the slot 100, without actuating the member 23. Referring to 5 Fig. 9 of the drawings, it will be seen that when the lever 17 is thus moved in the direction of the arrow B, the plate 104 engaging the sliding plate 107, will advance the same, together with the spring arm 110, The stud 115 will pass beneath the laterally projecting portion 119 of the spring plate 116, and be engaged by the curvilinear end 118 of the spring plate 116. If the finger lever 17 be 6 then moved in a direction contrary to that I indicated by the arrow B in Fig. 1, the head 115 will ride up, upon the spring plate 116, as shown in Figs. 8 and 13, withdrawing the teeth'1l2 from the slot 114. The stud 115 will ultimately drop from the laterally projecting portion 119, the teeth 112 entering again the slot 114, between the nails and the end face 8 of the hammer handle. This operation will be clearly understood by reference to Figs. 9 and 8, wherein the stud 115 is shown in successive positions, and by referring to Fig. 2, wherein the teeth 112 are shown in the relation to the nail 9 which they will assume before the operation hereinhefore described, has taken place.

The foregoing operation will suflice to show that when the finger lever 17 is moved in the direction of the arrow B, and then moved in a contrary direction, certain na1ls, which, by the inversion of the hammer, have been disposed in contact with the teeth 112, may be advanced toward the recelver-extension 10.

I will now describe the operationwhereby one nail is segregated from the receiver, and deposited in the receiver-extenslon The nails, by the operation herembefore described, will rest against the edge 102 of the slide 25, this edge 102 belng disposed across the opening between the walls 5 of the receiver. Presupposing that the relations between the finger lever 17 and the member 23 are those delineated in Fig. 5, it will be seen that when the finger lever 17 is moved in a direction opposite to that inclicated by the arrow B in Fig 1, the member 23 will cause the lever 21 to tilt, moving the free end' of the spring strip 20 away from the receiver, and causing the slide 25 to move in the direction of the arrow A in Fig. 2. As the slide thus moves, the tongue 27 will pass beneath a single nail and segregate the same from the other nails which are located between the teeth 112 and the slide 25. The head of the nail will then pass through the opening 103, the nail being prevented from sliding toward the claw end 3 of the hammer, by means of the covering 28. Recalling still that the hammer is in an inverted position, the nail will drop upon the anvil 16 and slide, as hereinbefore pointed out, into the position shown in solid line in the upper left hand portion of Fig. 1. After the nail has thus entered the portion 11 of the receiverextension, the finger lever 17 may be tilted into position shown in Fig. 1, the slide 25 being thus disposed in a position to prevent other nails from entering the receiver extension. This movement of the finger lever 17 will advance the head 35 into the opening 37, the beveled edge 36 of the head engaging the nail and thrusting the same against the upper portion of the flat end 11 of the extension, the nail thus being held securely in place to abut against the end of the anvil 16. It is of course obvious that when the lever 17 is manipulated to move the slide 25 in the direction of the arrow A, the head 35 will be withdrawn from the opening 37, and thus the nail will be permitted to move into the flattened portion 11 of the receiver extension. The nail may now be considered to beheld in the position shown in solid line in the upper portion of Fig. 1, in abutment with the end of the anvil 16, the beveled edge 36 of the head 35 thus holding the nail in place. The nail may then be tapped into the structure into which it is to be driven, a single blow obviously effecting this end. hen the nail is thus seated, the finger lever 17 may be manipulated, withdrawing the head from the opening 37. The hammer head may then he slid upwardly, whereupon the head of the nail will move out of the transverse portion 14 of the slot in the lower face of the end 2 of the hammer, the body of the nail passing out of the portion 15 of the said slot. The nail will thus be left protruding slightly from the structure into which it is to be driven, whereupon the nail may be driven full length into the material in the usual manner.

\Vhen the finger lever 17 is disposed as shown in Fig. 1, it will be seen that the finger lever at its free end may be moved to and. fro, to operate the slide 25, and to place nail after nail in the receiver extension. When, however, there are no more nails between the teeth 112 and the receiver extension, the finger lever may be tilted at its free end in the direction indicated by the arrow B, and more nails maybe advanced to a position adjacent the slide 25. the slot denoted by the numeral 100 permitting the nails to be advanced by the teeth 112. into a position adjacent the slide 25, without, however, operating the slide 25 itself.

Havin thus described the invention, what is claimed 1. in a magazine hammer, the combination with a receiver and a reeeiver-extension, of a slide operating as a segregating element between the receiver and the extension; a spring secured at one end to the outside 01" the extension and at the other end movable in the slide: a tiltable member pivoted to the receiver and interposed between the receiver and the spring to flex the spring: a movable operating member; and a connection between the operating member and the tiltable member.
