Specification of Letters ratent'. Patent d F b 21 1 2 Application filed m 8, 1919. Serial No. 309,379

To all whom it may concern y Be it known that I, GEORGE D. PARKER, a

citizen of the United States, residing at Riverside, in the county of Riverside and State of California, have invented certain new and useful Improvements in Crate-Head-Miaking' Machines, of which the following is a specification.

to an apparatus for automatically receiving and conveying the end posts and end pieces:

for a crate head to nailing position and nailing the end pieces to the said end posts; the invention being more particularly designed for the construction of heads for crates employed in connection with the shipment of vegetables, fruits and other commodities, which crates, with the exception of the heads, are formed by hand, that is to say, the side pieces employed in the construction of the crate are nailed by hand to the formed crate sembled members of the crate head moving to nailing position removes or ejects from the machine a previously completed finished crate head;

To comprehend the invention, reference should be had to the accompanying sheets of drawing, which illustrate the preferred embodiment of my invention, and wherein,

Fig. 1 is a perspective rear elevation of the apparatus, illustrating more particularly the hoppers for the end post and the hopper for holding the end pieces for the crate head, the means for removing the crate head pieces from within the respective hoppers and simultaneously advancing the same to nailing position, and the mechanism for actuating the working parts of the ap-pa ratus.

Fig. 2 is a'fr'ont elevation of the ;appa-.

. crate head. The hereinafter described invention relates closing the relative position of the working parts-of the apparatus and the mechanism for mpartlng movement thereto.

V Fig. 4 1s a cross-sectional top plan view,

taken on'the line 4-4, Fig. 2 of the drawings, viewed in the direction of the arrows.

Fig. 5 1s a perspective view of a finished ,Referring to the drawings, the numeral 1 1s used to lndicate any suitably constructed frame capable 'of sustaining the workin parts of thea'pparatus, and which frame in a suitable base plate 2., 'The frame 1 supports, approxlmately midway of its height an outwardly projecting shelf or table 3, and to the said shelf is adjustably supported by means of the angle brackets 4, the end post hoppers 5, which hoppers are arranged at an outward lnclination, each hopper being adapted to contain a stack of end posts 6, which posts feed downwardly within the sad hoppers for positioning the lowermost end post of the stacks onto the table 3 in ad- Vance of reciprocating means for removing or delivering the same to nailing position, as. hereinafter more fully set forth. Intermediate the said end post hoppers 5, is situated a vertically disposed hopper 7gwhich hopper 1s adapted to contain a stack of end pieces or shooks 8. The said hop-per at its lower end is supported or sustained by the table or bracket 3, and at its upper end the hopper members are adjustably connected for lateral adjustment to the transversely disposed bar 9. The hopper 7 is an open one, the shook or ends being sustained therein by an inwardly 1 projecting flange at the bottom of each member 7 Above the table orbracket 3 and held a slight distance thereabove is located a transversely disposed reciprocating feed bar 10; on said bar are mounted two slide heads 11, which work over the face of the table or bracket 3. The feed bar 10 is connected by links 11 to the upper end of the fulcrumed levers 12, the lower end'of each fulcrumed lever carrying a following roll 13 adapted to work within a cam groove 14 formed in the face of the cams 15, which cams are mounted on'the main shaft 16 of the apparatus. The said shaft 16 is driven from the drive shaft 17, to one end of which is the present case is upwardly extended from mounted a belt pulley 18; the shaft 16 de-,

ing with the gear 20 on the said main shaft 16.

To each head block 11 is adjustably connected aslide 21, each slide carrylng approximately midway of its length a dog 22,

, ble platform 24. Each reciprocating slide 21 carries in addition to the dog 22, a. plurality of shock or'end piece removing dogs 25 and26, which dogs 'arepivoted to the slides 21 and move through cut-outs or slots 27 formed in the face wall of the hopper for the end pieces or shocks 8. As the forward pair of dogs 25 move within the cut-outs 27 and through the hopper 7 the lowermost shook or end-piece 8 is moved from beneath the stack of end pieces and from within the hopper 7 while the next lowermost end piece or shook 8 is removed by the dogs 26 as they advance through the-hopper, carrying the end pieces or shooks in spaced relation to a position immediately above the nailing bases 23' so as to lie ediately above and transversely disposed relative to the end posts 6, which at such time rest on the said nailing bases. The action of the slides 21 is such, that on each inward reciprocating stroke thereof there is simultaneously ad- "vanced two end posts and two end pieces 8 to nailing position. When brought to this position; the nailin bases 23 are raised to cause the positione end posts 6 to elevate or lift the positioned parallel end pieces or shocks 8 from ed the dogs 25 and 26, which upward or vertical movement ofthe nailing bases 23 is produced by the upward lift of the platform 24 to which they are secured in any suitable manner. is provided withthe downwardly extended portions 27 carrying cam follower rolls 28, which are acted on by the cams 29 secured to a transversely disposed shaft 30 driven from the main shaft 16, through the medium of the intermeshing gears 31 and 32 mounted respectively on the shafts 30 and 16.

When the nailin bases stand in their full elevated or uplifted position with the transversely disposed end pieces 8 for the crate head resting on the longitudinally disposed end posts 6 supported by the nailing bases, the said end pieces are nailed tothe end posts by any'suitable type of nailing means. These means in the present case com rise the nail chucks 33 which receive nails om the nail feed tubes 34, which tubes in turn receive the nails from any suitable nail feed- The platform 24 nae-oases ing-mechanism (well known and common in the art), the nails being delivered from the' tilting nail hopper 35. As in nailing ma chines generally, within each of the nail chucks 33, is located a punch for forcing the nails from within the nail chuck 33 and driving the same through the crate headsuitable guide-ways of the frame 1. Thetrunnions 37 of the nailing head project through the slotted section 38 of the frame 1 and extend Within the trunnion blocks 38', spring-held Within the. yoke-heads 39, which yoke-heads 39 are secured to and carried at the upper extremity of the connecting rods 40 united at their lower ends by the wrist pins 41 to the driven gears 20 and 20 mounted on the ends ofthe main shaft 16 and which receive rotation from the drive shaft 17 through the meshing pinions 19 and 19. i j

The nailing head and the means for actuating the same is of'well known construcnail hopper 35 for the agitation of the nails therein for delivery to the nail feed is well known, it being understood, in the present case,that the said hopper is supported by, the connecting rods 42, which at their lower ends are secured to the levers 43 and said tion and calls for no detailed description as levers are actuated through the medium of the connecting rods 44, pivoted at their lower ends to the crank arms 45 secured to the transverse shaft 46, driven from the shaft 30 by a pinion thereon meshing with the gear 47 secured to the shaft 46.

v The slides 21 are adjustable, as previously stated, within the slide blocks 11 and are held in adjusted position therein b means of the set screws12', the purpose of t is adjustment bein that during certain working conditions o the machlne .it is desirable to change the position of the end pieces relative tothe nailing chucks, so that the nails will come to a difi'erent position relative thereto and it is therefore apparent that if the adjustment of the slide rods 21 be varied relative to the slide blocks 11, there will be a chan e in the positioning of the end pieces carrier? by the dogs 25 and 26 of the slide 21 relative to the nailing chucks.

The hopper 7 is made in two sections, Fig. 2 of thy: drawings, each member of angular fo and each member is adjustably connected tibthe transverse 'bar 9 by means of the screw bolts 9, which extend through said members composing the hopper 7 and pass through the slotted sections 9 of the' of such transverse adjustment being that the width of the hopper may be varied in accordance with shooks or end pieces of differpermit of the machine being utilized for the work on material of varying lengths, in order to provide completed heads or ends for crates of different sizes.

The invention primarily resides in the means for receiving and simultaneously advancing the members or parts constituting the crate head to nailing position, and in the means whereby the hoppers for the members to beassembled may be adjusted or varied to adapt themselves for varyinglengths of pieces for the productionof crate heads for usein connection with crates of different sizes.

While the invention has been illustrated and described in its preferred embodiment, it will be understood that it is not my wish to limit or confine the invention to the de-, tails of construction of the interconnected working parts herein shown and described, and I therefore wish to be understood as claiming the invention as broadly as the state of the art will warrant. 3 I
