To all whom it may concern.

Be it known that I, JAMES A, BRoeAN, a citizen of the United States, residing at Lawrence, in the county of Tjlssex and State of Massachusetts, have invented certain improvements chines, of which: the following description,

in connection with the accompanying draw ings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastening insert ing machines, and an object of the'invention is to improve machines of to sever nails from a'nail string and drive them into the work. i

A further object ofthe invention is to provide a machine for inserting string nails which will be adpated to operate on-a nail stringcomposed of relatively soft stock, for example, iron or brass wire, and to this end an important feature of the invent-ion resides in the provision in a string nailing machine, of mechanism for severing'the nails from the nail string and presenting them to the driver of the machine, constructed and arranged to form oppositely beveled surfaces on the'points on the nails,thus enabling them to be driven straight into the work and'also facilitating the proper clinching of the nails. H

The illustrated machine is of the type comprising a fastening receiving member having a passage to receive the endmost string guide nail or a nail string and a nail having a guideway for the nail stringand movable relatively to the fastening receiv-' ingmember to alzine the guideway with the passage of the fastening receiving member to enable the nails to be anda further feature of the inventionresides in the provision in such a machine means independent oithe nail string guide and the means by which the nails are fed for severing the nails from thenail stringfafter theyhave been introduced into the fasteningv receiving member.

Other objects and features of the invention will appear as the descriptionproceeds and will be pointed out in' the appended claims.

The illustrated machine comprises a column'2, upon which rests a superstructure i, on the front of which is supported a head mounted ona shaft 8 j ournaled in the superstructure 1-. The swinging'head 9 are views similar to Fig.- the part-s as. they appear at the cycle of operations of the 6 is maintained against the front of the 85 superstructure e by castings 10. Slidably mountedin the swinginghead 6 are a driver bar 12' carrying a driver 14 and anawl'bar 16 carrying an awl 18. The driver bar12 is raised by a cam on the shaft8 operating.

on the bar, and-is de pressed to drive the nails by. a spring 21 coiled about apart on the superstructure 4,.

The awlbar 16 i's-provided with:teeth 23 with which mesh the teeth of a, se ment-gear 22 fixed to a shaft 2 i'journaled in the super structure 4. An arm 26 on the shaft 24 carrise a roll 28 riding in a cam groove 30 in a cam .32 on the shaft 8." Theby means including a block' 33 adjustable in.

a groove-in the head'G, as clearly appearsfrom Fig. 1., On the-lowerend of the head 6 1s a fastening receiving member in the form ofa' throatSt having substantially ver-" 105 tical passages 36 and '38 operating connections 6O a view on an enlarged scale of "70 guides id to the guideways as in the driver 1d and the awl 18 respectively reciprocate. The nails to be driven are successively introduced. into the passage 36 when the driver is elevated out of the passage. Preferably, and as shown, the nails are controlled. during their movement through the throat passage 36 by a spring pressed finger 39 pivoted in the throat 3a.

The nail string is supplied to the machine on a reel 40 supported on the superstructure 4t by a bracket 4-2. The nail string is wound on the reel 4.0 and the reel is applied to the machine in such a manner that in the operation of the machine the nail string will be unwound from the top of the reel with the nail in the string arranged points down and with their heads disposed outwardly from the string, or to the left, as seen in Fig. 1. The nail string, as it is drawn from the reel passes through a guiding tube as mounted on the bracket 4&2, and the end of the string is introduced into a guideway d6 formed in a nail string guide 46. As shown, the guide 4-8 is formed with two guideways 46 to enable two nail strings of different characters to be supplied to the machine, and the nail strings are retained in the guideways by leaf springs 50 secured to the guide 48 by set screws or the like When two nail strings are supplied to the machine the reel 40 and guide as: are duplicated. The nail string guide lS is carried by a shaft 54: fulcrumed in the head 6 of the niachine. In order to oscillate the guide t8, the shaft 54. is provided with 211131111 carrying a cainroll 58 disposed to ride on the periphery of the cam The cam roll of the arm 56 is maintained against the eriphery of the cam 32 by a spring 60. he shaft 54% is mounted "for endwise movement in the head 4- to the end that the nails in the guideways 4E6 oi": the guide 48 may be selectively presented to the passage 36 of the throat 34. lhe endwise movement of machine by mechanism including a hand. lever 62 appearing at the righthand side of the machine, as seen in 1. The mechanism thus far described constitutes by itself no part of the present invention and is clearly disclosed in United States Letters Patent No. l,el0l,2"z',-,granted Dec. 27, 1921, on an application of George Goddu and Fred L. Mackenzie. A more complete description of such mechanism is accordingly deemed .unnecessary.

The nail strings on their way from the guide a8 pass through a supplementary guide 6% carried by a strip 66 pivoted at 68 on the machine frame and having an upwardly extending portion '70 normally engaging a lugf? 1 on the casting 10. i

he nail string is intermittently ted to the shaft 54: is efi'ected in the illustrated,

place on the guide by a plate introduce the endniost nail of the nail string successively into the passage 36 or the throat 3% by means including a blade 72 mounted in a holder 7a, in which it may be adjusted by a screw or the like 76. A set screw 78 on the side of the holder Telserves to secure the blade 72 in adjusted position in the holder. In the present instance of the invention, the holder 74 is carried by an arm 80 mounted on a shaft 82, upon which is coiled a. spring 8% tending normall to press the blade '72 against the opposite surface of the nail string guide 18. A cam roll. 66 on the lower end of the arm is disposed to ride on a cam surface 88 on the rear edge of the laterally extending portion 90 of the nail string guide 4:8. The cam surface 88 accordingly controls the blade 72 in its po-- sition with respect to the nail string guide Theshatt 82 is sleeved into the end of an arm 92 pivoted loosely on a shaft 94 journaled in the head .6 or" the machine. As shown, the arm 92 is extended rearwardly from the shaft 9d and is formed with a bowed portion 96, which terminates in an upwardly extending bar 98 channeled to receive a sliding block 100, to which is pivoted a lever .102 having a cainv roll 10% at its upper end riding in the cam groove 30 of the cam T is cam through the operating connections above described reciprocates the blade 72 in a substantially verti= cal direction along the side of the nail string guide 918.

The illustrated machine is particularly designed to operate on nail strings of relatirely soft material, such a nail string being shown in Fig. 2 and consisting of a wire bent or folded upon itself at intervals as indicated at A to constitute the heads of the nails in the string and having portions cut away at B to assist in torrning points on the shanks of the nails. The wire may be made of iron or brass, for instance, but is preferably soft enough to enable it to be cut or bent readily. in accordance with the invention, n'ieans is provided for severing the endrnost nail from the 'nail string after it has been iied into the passage 36 ofthe throat 34E of a character to cause the nails to penetrate the worlt. easily, so that they will not buckle wnen they are driven, and to be otherwise properly inserted into the worlr. As shown, such means comprises die plate 106 recessed into the lower end of the nail string guide 48 and maintained in headed pin or the like 108. The cutting edge 110 of the die 106 formed at the intersection of its lower surface 112 and the surface contiguous to the path of nioven'ient of the nail string. 'l he die plate 106 is so disposed with relation tothe upper surface of the throat Se that when the endmost nail of the nail.

be spaced inwardly from the inner surfaces guideways 46 of the nail string 116 of the I guide 18. Consequently; the point of the secondnail in the string is presented to the cutting edge of the die plate 106 at an angleto the contiguous surface 114 of-the plate. As shown; the inclination of the surface 11% to the shank of the nailis' increased adjacent to the edge 110,.as indicated at 118,].

but it is obtained apparent that'like results may-be by continuing the surface 114 at the same an le to the shank of the nail as atthe portion 118. Y

in the present instance of the invention,

the nail string severing means further coinprises a cutter having its edge disposed to abut substantially against the edge 110 of the die plate 106; and' wardly and upwardly from its edge, thus presenting a beveled surface "opposite the portion 118 of the surface 114 of the die plate 110. 'lVith thisconstruction, whenthecutter 1 0 is operated to sever the endmost nail from the nail 1100f the die plate surfaces are formed on the point of the second nail by the neveledend of the cutter 120 and the inclined surface 114 of the die platev 106, thus enabling the. nail to be easily ins serted into the work and hyreason "of the fact that the point of ,the'n'ail is about equallyv beveled on ea 11 side, practically insuring that the nail will be driven straight In making the nail string,"

into the work. the wire is preferably cutinore'than half the way through at the v points of the nails when theya're-severed from the nail string by the nailing machine are also reduced on their sides intermediate between the beveled surfaces formed bv the,

cutter'120 and the die plate lOG. In this way, a point is formed on the nails which-not only enables them to be driven straight but which may also be perfectly clinched. The cutter 120 is dovetailed into the split lower end of a holder 122, as shown in h1g1 8, and

may be maintained in any desired position of ad ustment in the holder 122 by a headed screw 124. Preferably, and asshown a post 125 is formed on the holder 122'in positionv to abut against the opposed surface of the nail string giude a8 in order to facilitate the setting of the'blade 120 in the holder. ,The holder 122 is pivoted on the nailstring guide 48-h means of'apin 126 extendinmiaterall froin'the nail string guide and passing I through the forked upper en'dof the holder.

eeing beveled back on the shaft 8; The. cutter 120 "moves in -a stringagainst the edge 106,- oppositely beveled points B, so that the A bar-128 secured rigidly to the swinging head 6 has its lower end extended forwardly (see Fig. 6) and received within the forked upper end of the holder 122in order to constrain the holder and, consequently, the cutter120 against movement with the nail string:

guide. when it is shifted to move one of the,

- guideways 16 of the nail string guide'out-of and the other into operative relationto the nail receiving passage .36 of the throat 3 In order to provide for'therelatlve move,

ments of the head 6 and the nail string guide 1 I 18, the bar 128 is formed at its point of con;

nection with the pin 126 an elongated slot 130. The cutter holder 122 is inoved away from and toward the nailstrin gui'de t8 toperinitthe nail string to be fed andto causethecutter 120,-to severthe nail string against the 'edgeof the die plate-106 carried bythe nail string guide by ineans'including alink 132'Icoinposed of rods united by an exp'ansible connection .134. "As shown, the

link 132 is connected to the cutter holder- 122by a screw 136and'is j'oined'at its other end by a pin 140 to-a'n arn1138inounted o'n thejshaft 94. arrn 138 is an arni 142 carrying agroll 1 14 riding on the periphery of a cam -1&6 fixed substantially horizontal path which is some what curved because ofthe pivot'alinounting ofthe cutterv holder 122, and the "upper sur face of the throat 3c'is curved title? to perinit suchinoveinent of-the-c'utte'r.
