To all 'whom 'it may concern:

Be it known that I, EMMET HoRToN, a citizen of the United States, residing in Elmira, in'the county of Chemung and State of New York, have inventedcertain new and useful Basket-Making Machines, of whichthe iol-v lowing is a specification.

The mechanism of -my present invention is more particularly designed for` use in nia-- chines of the typeV shown in my Patent, No. 760,791, o f May 24, 1904, and in my Patent No. 835,135 of November 6, 1906.(application i No. 274,301, :filed August 15, 1905) which patent shows nailing mechanism of substantially the same construction as that herein shown in connection with a fully organized machine for. the manufacture of baskets of wood veneer. y

`This a plication is a division of my application above mentioned.. i

The primary object of my inventiones to shall operate more eiiiciently vto -form and drive staples. l i A further object of my invention isto pinvide improved means for renewing the wearing surfaces of the staple-forming sleeves. v The accompanying drawings illustrate nailing mechanism embodying my improvements and adapted for use in machines of the but it will be understood-that' some features of my improvement may be embodied in nailing mechanism for use in other machines.

Fig. 2 shows a vertical, longituliiw. 3 is a view on an enlarged scale oi' the haiii- Fig. 4 shows an end elevation of the nailing mechanism.

The base plate, 1, is similar ingeneral Iconstruction to that shown in my Patent No.

760,791, of May 24, 1904. It has a front upwardly projecting portion or nailer-head, 2, and an upwardly projecting rear portion, 3. The nailer-head, 2, is bored to receive two parallel `staple-forming sleeves, 4, while the back-piece, 3, has bearings closed by caps, 5, to receive the hammer rods, 6, which reciprocate therein.' Each hammer rod is formed It has an cate in the bearings in the back-piece, 3; a screw-threaded portion, b, to receive the nuts, 7, shown in Fig. 2 asholder, c, and a socket, d to receive the hammer, e. A shoulder, d', is formed on the rod at the front end hol" the socket, for a purposelhereinafter eX- 0; 274,301, filed August 15, i905 piained.

The hammer and hammer rod are of substantially Vthe same construction as that.

'shown in my prior machines above referred to.

ing shortens the rod. `By means of the adjustable connection described, the loss by grinding may be compensated and yet the relation between the shoulders d and 19 hereinafter referred to, is not -elianzgnnl and the spring, 17, also vhereinafter referred to,

operates in the same manner at all times.

The cross-head is driven by a pitman or connecting'rod, 9, thc driving mechanism not being illustrated but it may be the same as that heretofore employed by me. 10, are attached by set screws, 11,V to the hammer rods in. rear of the cross-head and springs, 13, are interposed between the front end of `the cross-head and the nuts, 7. These springs have considerable strength and press the cross-head firmly against the collars, 10, but permit the cross-'head to move to a Small The hammers and hammer rods are diskposed parallel to each other and reciprocate v Collars,

extent toward and from the collars.- The cross-head is formed with a downwardly projectinl bifurcated front portion, 14which strad es a guide-rail, 15, on the upper snrface of the bed-plate. -lhe lowerportion of the cross-head. is beveled on opposite sides at 16 for a pur ose hereinafter explained. The stap e-forming sleeves, 4, are in gen- 1 Fig. 2. Sprl eral construction similar to those shown in my patent and application above referred to.

l They are enlarged at their rear ends to form collars, 18, and they receive the hammers and hammer rods, in the manner indicated in s, 17 are interposed between lthe shoulders, of the hammer 'rods and the shoulders, 19, in the sleeves and tend to move I videayieldi the sleeves forward away from the hammer rods when under compression, and they proconnection between the hammer rods an 'the sleeves. The hammercarrying cross-head, 8, carries a lever, 20,

ivoted at 21 to the portion, 14, of the crossheadandadapted to engage the collars, 18. The shorter arm of the lever is held down by a spring and nieves in a recess, 22, in the guide-rail, 15. When the cross-head, 8, is' moved from its rearmost position forwards, a

rigid connection is provide'l between said cross-head and the .sleeves so that the latter are moved Vpositively forwards the required distance but las soon as the end of the short --arm of the lever, 20, comes in contact with the inclined surface, 23, the lever is moved from engagement with the collars, 18, so that forwards but are held 1n the sleeves are no 'longer moved positively place or move forwards further by reason of the yielding connection, 17, between the hammer rods and the sleeves. A rod, 24, is rigidly connected by means ofa set screw, 25, with the cross- 'head,8, and carries on its opposite end a l block, '26, which is adapted to engage the collars, 18. The arrangement is such that when the cross-head, 8, moves forward the rod, 24,

moves away from the collars, 18, but on the return movement of the cross-head the block,

l26, will engage the collars and cause the staple-forming sleeves to move -rearwards positively. Each staple-forming sleeve is rovided with .a removable cutter, 28, of ard steel Which coperates with another cutter at the point, 29, as heretofore. Each sleeve is also provided with two removable wearing surfaces or blocks, 30, which are arranged in vdove-tailed recesses in the end of the -sleeve and are held in place by set screws,

31. These blocks are fgrined with grooves,

r32, as illustrated 'most clearly in Fig. 8, and f are so disposed as to receive the staples as they are formed and accommodate the ribs, 33, of the hammers. I find that by usin separate blocks of this kind, harder materia maybe employed and the blocks -may be Withdrawn and replaced when' worn, 'very conveniently. I Each staple-forming sleeve is formed with ailongitudinal slot or recess,

34, to accommodate an anvil, 35. The nailer head is also slotted or recessed to -accommodate the anvils.- The anvils, 35, have arms, 37, projecting through the slots in the nailer head and in the sleeves and these arms are adapted at times to project across the bore of the sleeves. These anvils are attached to bell-crank rocking levers, 38, pivoted at 39, to the bed-plate. The arms; 38 of these bellcrank levers are adjustably connected with the anvils while the arms, 382, are arranged to engage levers, 40, pivoted to the bed-plate and having rear ends, 41, adapted toengage the inclined surfaces, 1 6, ofthe nailer carrying cross-head, 8. Springs, 42, attached to the nailer head and to the levers, 38, -pull the levers in one direction, tendingto move the anvils across the ends of the staple-forming .sleeves while the anvils are moving in the opposite direction to withdraw them from the sleeves by means of the levers, 40.

The wire for forming the staples is fed inthe usual way along guides, 13. The guides, 43, however, differ in detail from those heretofore employed. Each one of them consists of a short cylindrical rod having a longitudinal groove on one side as clearly shown in Figs. 1, 2 and 4L. The guide groove is therebeveled surfaces, 16, engage the levers, 40,

and cause the anvils to be withdrawn before the hammers are advanced; then the ham-- mers advance and drive the staples out of the sleeves into the basket. As soon as the staples are driven, the cross-head, 8, retreats, the hammers are withdrawn and then the staple-forming sleeves are withdrawn to their former position. 'lhe mechanism by means of which the anvils are withdrawn from the nailer head before the hammers are advanced is considered of great importance as serious inconvenience would be encountered if the hammers were operated before the anvils were. completely withdrawn.

l have shown two staple-forming and conjointly. It will be understood, however,

that my invention contem lates also mech-l anism for forming and dri ing a single staple br similar securingrlevice.
