- Each wall I34 and associated flanges etc. described hereinabove comprises one half of the hopper I35 and may. therefore, be referred to as a hopper half.
- This hopper comprises the main portion of the magazine 52 in that it feeds the posts, slats and panels downwardly into the path of the conveyor 53.
- This conveyor operates to feed shook from the magazine 52 and assemble this in proper relation so that when this is nailed together it will produce a crate head.
- This conveyor (see Figs, 5 and 8) includes a pair of drive sprockets I having sleeve hubs I 8I which are suitably journalled in beams IIJI. It also includes driven sprockets I82 which are rotatably mounted on studs I83 fixed on the beams I III at the rear end of the magazine 52.

Portions of the magazine 52, the conveyor 53, the
path of travel of the work through the machine.
Frame 50 veyor drive shaft bearings 16 (see Figs. 5 and 6). The frame bars .H are also connected by a fixed shaft 18. The spider 12 has a pin recep-- tacle 11. The spider I3 (see Figs. 6, 8 and 36) has a jack shaft bearing 88 (see Figs. 8 and 36) a pawl pin bearing 8| (see Fig. 6), an-idler arm stud 82 and a spring rod ear 83 (see Fig. 36).

The members I00 are provided with right and left-hand threaded nuts I8 4 (see Fig. 8) into which shafts I05'are screwed. These shafts extend through suitable openings in the wall 62 and through brackets I06 provided on these walls, these shafts being held against axial movement relative to said brackets by sprockets I01 and collars I08 fixed on these shafts. Trained about the sprockets I0! is a chain I09 which causes the rotation of either of these shafts to rotate the other in synchronism therewith. The ends of these shafts are squared and are adapted to be rotated as by the application of a crank H6 thereto.
The upper edges of the beams llil (see Fig. 17)
are on the same level as the upper faces of the horizontal border decks 64. Lying on these decks and these beams, and welded to the latter, are a pair of deck plates H5 which extend throughout the length of the machine. The outer edges of the plates H5 are held in snug sliding relation with the horizontal border decks 64 by bolts H6 these decks (see Fi 2).
The bearing spiders l2 and Magazine 52 This magazine is best shown in Figs. 13, 14, 15,
7 plates H5. Each section H8 includes front and rear brackets II9 and I20, which supporta rail hopper I2I extendng upwardly outwardly therefrom at an angle of about 45. The hopper I2I has a rod I22 extending across its upper edge and which is mounted on an adjustable rail flusher I23 which lies on the rear side of the hopper and is capable of being shifted to adapt the hopper I2I for rails of different lengths. The hopper I2I has guide strips I24, the lower ends of which are curved upwardly (see Figs. 13 and 17) so as to deliver rails onto the top of magazine track plates I25, the inner edges of which are flushed with the inner edges of the deck plates H5.
Extending between each pair of brackets H9 and I20 is a rod I which carries aspring guide I3I which guides the rails R- onto the curved portion of the'guide strips I24. Provided on the brackets H9 and I20 are inwardly extending arms I32. and I33 (see Fig. 13). Disposed just inside of and secured to each pair of these arms, and extending upwardly therefrom, is an end wall I34 of a multiple post slat and panel hopper I35. Each of the walls I34 has front and rear flanges I36 and I31 and has horizontal slots I38.
The space within the post slat and panel hopper I 35 is adjustably divided by vertical guide members I 39 and I which are secured to the hopper end walls I34 by bolts I4I extending through the slots I38. A panel hopper I is thus provided between the two walls I34, the two flanges I36 and the two vertical guide members I39.
A slat hopper I46 is likewise formed between the vertical members I39 and I40 and a post hopper I41 is provided between the members I40 and the rear end wall flanges I31. When the shook is placed in the hoppers I45, I46 and I41 the ends of the shook are guided by guides I50, I5I, I52 and I53. Of these the guides I50 are secured to the magazine end walls I34. The guides I5I and I52 are provided on the vertical members I39 and I40 respectively and the guides I 53 are fixed on the ends of spacers I 54 which are secured to the end walls I34 by bolts I55 passing through the slots I38. The reason for the guides I53 being on spacers I54 is that the posts 0 for which the hopper I41 is provided are considerably shorter than the slats and panels for which the hoppers I46 and I45 are provided. I
Secured to the outer face of each wall I34 ad jacent its lower edge and opposite the hopper I45 is a sheet angle member I (see Figs. 13 and 17) which provides an inwardly extending shelf I6I on these shelves supporting opposite ends of a load of panels P .which may be placed in the hopper I45. The lower ends of the front hopper end wall flanges I36 and the adjacent portions of the bracket arms I32 are disposed above the shelves I6 I the latter extending forwardly thereunder. Adjustable panel retaining gauges I62 are secured to the arms I32 and are substantially coextensive in length with the forward. ends of the shelves I6I (see Figs. 14 and 16).
Adjustably secured on the vertical members I39 (see Figs. 13 and 14) by cap screws I63, are slat retention members I64 which extend a substantial distance inwardly into the multiple hopper I 35 and lie just in advance of the slat hopper I46.
3- Secured to the'lower ends of guides I53 and ex-- tending forwardly beneath the slat and panel hoppers I46 and I45. are yleldable slat supporting guide arms I65 (see Figs. 14 and 17).
The bottom ends of the vertical guide members I40 are provided with inclined guides I68. Disposed inwardly somewhat from these guides, and
, supported on bracket arms I33 (see Figs. 13, 14
and 15), are post supports I61 having inclined portions I68 which are parallel with guides I66 and each of which is provided with an escapement mechanism III. This mechanism includes a rocker lever I 12 having end fingers I13 and I14. This rocker is normally held in the position in which it is shown in Fig. 15, by a spring I 15, but is capable of being rocked into the position in which it is shown in Fig. 14 by the feeding of post 0 forwardly from the bottom hopper I41. Each wall I34 and associated flanges etc. described hereinabove comprises one half of the hopper I35 and may. therefore, be referred to as a hopper half. This hopper comprises the main portion of the magazine 52 in that it feeds the posts, slats and panels downwardly into the path of the conveyor 53.
This conveyor operates to feed shook from the magazine 52 and assemble this in proper relation so that when this is nailed together it will produce a crate head. This conveyor (see Figs, 5 and 8) includes a pair of drive sprockets I having sleeve hubs I 8I which are suitably journalled in beams IIJI. It also includes driven sprockets I82 which are rotatably mounted on studs I83 fixed on the beams I III at the rear end of the magazine 52.
Extending through the sleeve hubs I8I and having splined connection therewith is :a drive shaft I84. Fixed centrally on this shaft is a driven sprocket I85, end play of the shaft being prevented by yokes I86 mounted on the frame shaft 69 and disposed close to opposite faces of the sprocket I85.. Trained about the sprockets I80 and I82 are conveyor chains I88 (see Figs, 5, 8, 9, 10, 11 and 12). In Fig. 8 these chains are diagrammatically shown. In the normal functioning of the machine 50, these chains travel intermittently about the sprockets I80 and I82, these chains being comprised of a number of shook picking units I89 (see Figs. 11 and 12),
each of these units including a front post and cludes a pick I which is pivotally mounted on v a chain pin I96 and is connected by a link I91 to a high link plate I98. The pick I95 .is provided with a pin I99 which limits the rotation of a front post positioned 200 which is also pivotally mounted on the pin I96. The positioner 200 has a roller 205, the purpose of which will be made manifest hereinafter.
Each half, of each device I9I includes a plate 206 which is fixed on one of the link plates of the chain I88 and has a slot 201 which receives a bolt 208 and rigidly positions a spacer 209 in this slot. Pivotally mounted on this spacer is a panel pick 2I0, this pick having stop pins 2H and 2I2 and a roller 2I3. The pins 2H and 2I2
