ATTACHJIIENT FOR NAILING-MACHINES.

To all whom 'it may concern:

Be it known that I, Percy L. BILLINGSLEY, a citizen of the United States, residing at 1 Oak, in the county of Marion and State of Florida, have invented certain new and useful Improvements in Attachments for Nailing-Machines; and I do hereby declarefthe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to attachments for nailing machines and my object is to provide means for automatically feeding the parts to be nailed, below the nailing head.

A further object is-to provide means for supporting the objects to be nailed in position on the feeding device and a still f1. rther object is .to provide means for adjusting the several parts of the device, whereby objects of various sizes may be placed on the feeding device.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a side elevation of my improved feeding device in its operative position. Fig. 2 is an end elevation thereof. Fig. '3 is a view as seen on line 3-3, Fig. 1. Fig. 4 is a bottom plan view of a feeding plunger, showing the supporting frame therefor. Fig. 5 is an edge elevation of one section of the feeding 6 is an elevation of the lower end of one section of the magazineemployed in holding the articles on the feeding device. Fig. 7 is-a similar view of the opposite side thereof. Fig. 8 is a bottom plan view thereof. Fig. 9 is a side elevation of an arm employed for automatically operating the nailing device, and, Fig. 10 is an edge view thereof.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 and 2 indicate standards which are employed for forming the frame of my improved feeding device, said standards being secured together in any preferred manner, as by means of beams 3 and 4, said beams being extended transversely between the standards 1 and 2. Preferably. formed integral with the upper ends of the standards 1 and 2 are plates 5 l and 6, respectively, said plates extending 1n-- channels 32, at

Wardly from the inner faces of the stand- Specification of Letters Patent. Application filed August-.19, 1907.

ards to form a bed plate and are reinforced on their lower faces by means of webs 7 Mounted upon the plates 5 and 6, are guide rails 8 and 9, respectively, provided with a plurality of ears 10 and 11, respectively, through which extend clamping bolts 12 and 13, respectively, the ears 10 being provided with slots 14, so that the guide rail 8 may be adjusted towards or from the rail 9 to accommodate objects of various sizes. The upper faces of the guide rails 8 and 9. are provided with grooves 15, and 16, respectively, in which are adapted to extend tongues 17 and 18 of magazine forming sections 19 and 20, said sections being preferably formed of angle iron and mounted on base plates 21 and 22, respectively, to which the tongues 17 and 18 are fixed and in order to adjustably secure the magazine forming sections to the rails 8 and 9, bolts 23 and 2t are introduced, respectively, through the base plates 21 and guide rail 8 and the plates 22 and rail 9. The magazine sections 19 and 20 extend vertically from the base plates 21 and 22 and'in order to reinforce the sections 19 and 20, brace members 25 and 26 are formed integral with the base plates and magazine sections and extend upwardly on the magazine sections a sufficient distance to thoroughly brace said magazine sections and two of the brace members are provided for each magazine section and extend at right angles to each other, thereby thoroughly bracing the magazine sections in both directions.

This device is adapted more particularly for feeding box ends below a nailing ma chine, said box ends consisting of a frame 27, to which is secured a strip of veneer or the like 28, said frame and veneer, when secured together, forming such as is employed for shipping fruits and by providing the magazine, a large number of the frames and strips of veneer may be placed in position to be fed below a suitable nailing head, (not shown), automatically and to accomplish this result, a plunger is reoiprocatingly mounted below the magazine, said plunger being preferably formed in two sections 29 and 30, respectively, which sections are secured together by means of a connecting plate 31. The plunger sections 29 and 30 are adapted to travel on the plates 5 and 6, respectively, while the inner edges of the guide rails 8 and 9 are provided with their lower edges, in which extend tongues 33 on the meeting edges of which rails are the end of a box sections will be prevented.

with a plum lty 35, which extend through connecting plate 31 and by connecting plate is adjustably secured to the I means of stud bolts to the plunger through the medium 0 suspended above the plunger section 29, while the opposite edge of the plate 31 is fixed to the section 30 by 36. The forward edges of the plunger sections 29 aiid 30 are provided with feeding lates 37, one edge of which extends beyond the ends of the sections 29 and 30 of said projecting edges are beveled on their lower faces to cause the feeding plates to positively engage the section of veneerplaced above its respective frame 27 and cause the veneer to move with the frame.

In operating the plunger to cause the same to travel below th ofthe frames and tion to be nailed to e magazine and move one gether, power is applied a lever 38, one end of which is 'pivotally secured between brackets 39, at the lower ends of the standards 1 and 2,- while the upper end of said lever is pivotally-secured to an car 40, depending from the central portion of the connecting plate 31, through the medium of a pitman 41, said pitman being adjustable longitudinally, to adjust the position of the plunger. The lever 38 is rocked in its bearing by means of an eccentric 42, carried by a drivin' shaft 43, said eccentricbeing secured to the ever 38 at a point between 1ts lower end and longitudinal center by means of an adjustable eccentric rod 44, and by this construction it will be readil seen that as the driving shaft 43 is rotate the lever 38 will be swung back and forth, which will move the plunger below the magazine and automatically feed the frames, tained' therein, to the nailing device, the frame and veneer moving onto a platform 45 of the nailing machine, said platform eing secured in any preferred manner to one end of the plates 5 and 6 and in saline ment therewith.

The veneer is secured"- to the frame by placing nails through the veneer and into the frame and to complete'the nailing at one stroke, a head, carrying the requisite number of nails to'secure the veneer in position, is frame and the veneer an lowered into engagement therewith, the force of the head being sufiicient to drive the nails into the veneer and frame, but, as the nailing machine forms no part of my invention, I deem it unnecessary to show more of the nailing machine than is re uired to demonstrate the full operation o my imare adapted to receive simi- 7 bearing sectionof veneer in posit and veneer conthereby rocking with the action proved feeding device and, with this end in provided means for automatic-, ally operating the nailin view, I have g machine, so that the veneer will be secured to the frame, as soon as the same has been deposited on the platform, which consists of a bar 46, mounted adjacent its upper and lower ends in bearings 47, carried y the beams 3,said bar being vertically disposed and bifurcated at its upper end to receive a roller 48, that portion of the bar extending through the upper 47 being preferably square, so that the bar will be prevented from rotating in its bearings, at the same time allowing the bar to freely move longitudinally through the bearings.

A bracket 49 is adjustably secured to the w bar 47, adjacent its lower end, said bracket being adapted to engage the free end of a rocking lever 50, which is in turn secured in any preferred manner to the nailing head, so that when the rocking lever 50- is depressed, the nailing head will be likewise lowered into engagement with the frame and veneer thereon and in order to operate the rocking lever, co-incidentto depositing the frame andveneer on the platform 45, an arm 51 is secured to the plunger sections 29 andi30 and depends therefrom, to the lower end of which is adjustably secured a head 52, which is adapted to engage the roller 48 and depress the lever'50, through the medium of the bar 46 and bracket 49, the engaging end 53 of the head 52 being disposed substantially at an angle of 45 from the horizontal. The arm 51 and head 52 are vslightly curved and are secured together by means of a bolt 54, carried by the'head 52 and extended in the arm 51, thereby allowing thehead 52 to be readily adjusted on the arm 51, to give a longer or shorter stroke to the bar'46 and it will be readily ger moves forwardly to deliver the frame andveneer onto the platform 45, the in-. clined portion of the head 52 will enga e the roller 49 and cause the bar 46 to descen the lever 50 and o crating the nailing head. As soon as the p returned to its initial position, the bar 46 is elevated to its initial position by 'meansof a spring 56, which is interposed. between the a collar 57 on the bar lower bearing 47 and 46, the tension of the spring 56, together of the rocking lever 50 on the bracket 49, being suficient to readily elevate the bar 46, extreme lower end of the rod 46 engages the lower edge of the lower bearing 47, thereby limiting the bar. When the magazines are filled with the frames and veneer, the lowermost frame will rest in the magazine sections are elevated to such an extent that substantially one-half the thickunger is 3 until the collar 58 on the the upward movement of through an elongated 'slot 55 seen that as the'plunpath of the plunger and the ness of the second frame is below the lower ends of the magazinesections, so that when the plunger sections move below the magazine, those frames above the frame resting on the plates-5 and '6, will be held in their elevated position until the plunger is returned to its initial position, when all of the framesand veneerwill descend until the next succeeding frame rests upon the plates 5 and 6, the parts of the nailing device and the feeder being so timed that the veneer will be nailed to the frame by the time-the plunger reaches its initial position and'ready to deliver another frame.

- It will thus be seen that 1 have provided a very cheap and economical means for automatically feeding-the parts of a box head in positionto be nailed together and it will further be seen that the operation of the feeding device may be ignpl'oyed to operate the nailing machine, so that the two devices will operate in conjunction and it will further be seen that by employing the automatic means of feeding the parts to be nailed together, the output of the nailing machine may be greatly increased and the box produced at a greatly reduced cost and, still further, it willbe seen that the several parts of the feeding to accommodate frames of various sizes.

"What I claim is:

In a feeding device, the combination of plates and guide rails on said plates adjustable one with relation to the other, said guide rails having their, upper surfaces device may be adjusted grooved, of a two-section laterally adjustable plunger adapted to reciprocate between said guides; and a hopper arranged between the guide' rails for containing box ends and discharging the box ends in the path. of travel of the plunger, said. hopper having tonlgues extending within the grooves of the m1 s.

In testimony whereof.I have signed my name to this specification in the presenceof two subscribing witnesses.
