NAILIlfTG-MACHINE.

To all whom it may concern Be it known that I, IIENRY W. Monean, of Rochester, in the county of Monroe and I State of New York, have invented certain new anttuseftil Improvements in Nailingliflachines; and .I do hereby declarethe following to be a full, clear, and exact descriprim of the same, referencebeing had to the accompanying drawings, 'forming a part of this. specification, and to the reference-m merals marked thereon.

. The present invention relates to nailing machines for boxes or. other articles where two Work pieces, such as the sides of a box, are held in juxtaposition and preferably.

-in: angular relation while being secured to gether, and an'object of. the invention is to" provide for simultaneously'nailing together two proximate sides of a box or the. like while at thesame time applying astrap to both of said sides.

' Another object of the invention is to provide a machine which whileholdingtwo workpieces in definite intersectingplanes,.

will press or move them'towar'd the point of intersection of their planes in orderthat' a tight -joint may be obtained between the.

work pieces prior to'their being secured together.

In this waya boxis provided having an inner wall which has a continuous-surface except at the ends of the cardboard and these are located at a corner in a groove in a corner piece a. To..support two sides of a boxsuch as described or for that" matter any two angularly'arranged work pieces while the corner or joint {between them is being operated upon, there' 'may be ,provided 'a support-"or anvil preferably having two faces "1 at angles toea'ch other'so as to fit withinthe corner and engage thetwo work pieces. In this instance the support moves toward a nailing mechanism, to be hereinafter described, and to this end the frame .\"of the machine is rovided on its 'front facenvith vertical gui es 2 on which the support travels, 'the movement being effected by; any

thereto in any suitable manner.

The pawls 62 and 64, which act under the influence of gravity, engage the outer faces of-the work. pieces, while the inner faces of the latter. are engaged by pawls 63 and 65 which are projected by a spring 67 that connects them.

A further feature of this invention is the applicat-ioirof straps to the work on the work support in a position to be. secured by the nailing mechanism. I11-this"embodimerit, a. pair of plates or members 60 and 61 are arranged in-angular relation and are preferably secured to the chucks at the discharge ends thereof, the plates having provision wherebv the nails or fasteners may .bepassed thcrethrough to engage the straps.

These plates act to shape the straps fed In this instance, a spool or reel 68 for sheet metal tape 69 is arranged on the machine and supplies the tape to a feeding mechan sm comprising preferably a roller? 0 arranged on a resiliently mounted support 71 and pressed toward, a roller 72 that has a grooved periphery and'is journalcd on a shaft 73.

The latter may have an intermittent driving connection with roller 72 and to this end the roller has beveled projections or teeth 74 on one face with which a pawl or spring xpressed plunger 75 cooperates, the latter be- .ing carried by an arm 76 on the shaft 73 which is preferably operated manually. This may be effected by a lever 77 on the shaft 73 provided with a hand grip 78 which is'grasped and turned in a direction to cause the pawl or dog to engage a tooth 74 and rotate the wheel or roller 72, thus feeding the tape: 69, the return movement of the roller 72 being prevented by any suitable means, such as a spring dog 90 carried by a fixed part of the machine and engaging shoulders 91 on the roller. The tape may pass from the feeding device to a guide 79 which connects',with a guide 80 formed by l abore in the clamp 58 discharging to the wvardly in the groove until a stop 82 is reached when a continucd movement causes the tape to buckle 0r flex m the manner "ishown in, Fig. 11. About this time a cutting device may be-brought into operation to sever or cut a strap from the tape. -The cutting device may embody a stationary knife 83 mounted in a slot in the clamp 58 and adjustable by a screw" 83 to cause its cutting edge to project-different distances from the clamp. Coope 'ating with the knife is a movable knife 84 which may embody a U-sha-ped member ha ing its arms lying on opposite sides 0 the clamp and pivoted to the latter by a pi 1 $5, the portion connecting the arms operating past the discharge end of bore 80.

' The cutting device may be operated in any suitable manner, but preferably it is controlled by the tape feeding mechanism. With this end in view an arm 86 is secured one end to pin and at its free end carries a pin 87 which engages the walls of a notch 88 in an arm 89 on shaft 73 near the latter part of the feeding movement causing the knife 84 to cooperate with knife 83 and cut or sever the tapeto form a strap which is supported by engagement with 'the stop 82 and end of clamp 58. After the cutting operation the knife 8- rises under the action of the lever or arm 86 which is heavier than the knife.

In using the present embodiment of the invention, two work pieces, in this instance two sides of the box or the like. are placed upon the work support while the latter is in a depressed position, and grip 78 is grasped and the lever turned 'in order to feed the tape 69 to the position shown in Fig. 11. the knife S l opera ting immediately this position is reached. If desirable the treadle is now depressed carrying the work toward the strap which is shaped by the plates 60 and 61 and the work. If the work and the straps are positioned properly the clutch 13 is operated to start the machine, causing the work to be firmly pressed against the clamps 5S and 5!). Before the clamps 58 and :39 are reached the shiftingv puwls or dogs 62 and 6t engage the work pieces and together with the pawls 63 and 65 press or move the work pieces toward the point of intersection of their planes and in this manner holding the parts tightly together so that they may be secured in this relation by the nailing mechanism. \Vhcn the end of the upward movement of the work sup port is reached the nailing mechanism comes into operation and drives the nails in the two sides of the box to secure said sides together and at the same time attach the strap thereto.

A machine constructed in accordance with this invention is simple in operation and not liable to get out of order. It forces the work pieces into intimate connection prior to the nailing and the nailing devices operate-1n a manner to effectively secure the parts together. The straps are'formed and fed in a simple and expeditious manner thus reducing the cost of manufacture of boxes and waste due to the improper positioning of the work. y 4 straps. I I 8.
