The mill 12is mounted on base portion 17 which eX- tends the `full length of the device. Asv seen in Figs.` l and'9, `this `base portion -has` a bottom wall 18, a front wall 19 and a downwardly and rearwardly slopingtop Wall 20 forming rthe hollow interior 22. The mill 12 is Welded or by other suitable means atlixed at 25 to the upper surface of wall 20 so that front wall 26 `of the mill is substantially vparallel to andintegrally connected with wall 19. l

Connected to the

walls

76, 78, of rear section 73 3 and

walls

18, 19 and 20 of base section 17 of station 70 is a flat end wall 82.

A pivotable member 84 (Figs. 2, 5, 7) is mounted by pins 86 to the mill wall 68 opposite to wall 26 and end wall 82. This pivotable member has a at portion 90, in substantially the same plane as the lower end 51 of bracket S hereinbefore described, an upwardly ilanged portion 92 and a downwardly sloping forward eXtension 94.

In operation, when a lumber plank 60 has been trans- Aferred from hidden pocket 54 through mill 12 through openings in walls 26 and 68, it will come into view as it slides onto flat portion 90 of member 84. By means to be later described, member 84 is pivoted about the pin 86 (Fig. 8) so that plank 60 will slideoff member 84 down the sloping wall 72 and come to rest in wall 20 in a position indicated at 60 (Figs. 1 and 3).

At the same time the rough lumber 62, which has been simultaneously conveyed by the same means, will be carried from its visible position through openings in walls 26 and 68 through mill 12 to a hidden position behind wall 72 and extension 94 of member 84. This rough lumber will be discharged from the device to the rear, obscured from view, where it may be collected for further use by replacing it on the sloping wall 20 of station 28.

In Fig. 2 there is shown a constant speed motor 14 mounted to a bracket 100 which is affixed by conventional means to a portion of the mill 12. A rachet gear 102 is mounted at the lower end of the drive shaft 104 and engages reduction gearing 16.

Aixed by screws or other suitable means to the walls 36, 38 (Fig. 9) of section 28, and rear wall 108 (Fig. 3) of mill 12, is a U-shaped bracket 110 (Fig. 9) to which is mounted the driving means for the lumber 60-62 which causes them to move in the direction of arrow 64 (Fig. l).

These drive means includes a chain 112 threaded between the sprocket gears 114, 116 which are mounted on

shafts

118, 120. These shafts freely rotate in openings 122 in bracket 110. This mounting is illustrated in Fig. 9 for one shaft and the other is mounted in like manner. 'The shaft 120 is connected through shaft extension 121 to a gear 125 from whence it receives its drive power.

Axed to chain 112 is a paddle 130 by conventional means. 'Ihis paddle has an upper arm 132 which extends substantially horizontal and will engage one end of the nished lumber plank 60 resting on extension 51 of bracket 50 in pocket 54.

The lower arm 134 of paddle 130 is substantially circular, and will engage the end of a round piece of rough lumber 62 resting on the inclined wall 20.

It is seen that as the chain is driven by means of motor 14 through gearing 16, shaft extension 121, gear 125 and shaft 120, the

arms

132, 134 of chain paddle 130 will engage a piece of finished lumber and a piece of rough lumber and simultaneously carry them as hereinbefore described from station 28 to station 70 through openings in opposite side walls 26, 68 of mill 12. The rough lum ber sliding along the rear edge 63 and 71 of Wall 20 and the smooth lumber along portion 51 of partition wall 50 and flat portion 90 of member 84.

As paddle 130 approaches the shaft 116 the curved surface of the paddle arm 134 will engage the clip cam 136 mounted to at portion 90 of member 84 (Fig. 6) and this clip cam will cause by its camming action, a pivoting of member 84, as hereinbefore discussed, about pin 86.

A second cam member 140 (Figs. 5 and 7) is also mounted on the inner surface of extension 94 of member 84 to insure that the rough logs will be positively ejected from the device towards the rear.

As the chain 112 continues in its path around

shafts

118, 120 continuous operation results that will give the illusion to the observer of rough lumber being transported to the saw mill and coming out as iinished planks.

As the rough lumber 62 moves into saw mill 12 under 4 the push of paddle its lead end engages a contact arm 146 (Fig. 9). This arm is connected by means of a rod 148 to a fan shapedmetal plate 150. Plate 150 (Fig. 2) is normally held in the position 150' away from rotating toothed gear 152 mounted to the upper end of shaft 104 by a spring 156 (Fig. 3).

As the arm 146 is moved by the lead end of log 62, it pivots metal fan against the action of spring 156 so that the fan engages rotating toothed gear 152. The audible sound resulting from this contact will for all intents and purposes be a reproduction of the normal sound of a saw cutting lumber in a saw mill.

When the rear end of log 62 passes by the arm 146, and pressure is released from arm 146, spring 156 will disengage the fan 150 from gear 152 and return fan 150 to the position 150 for further action when arm 146 is engaged by the forward end of the next log 62 entering mill 12.

I have described what I believe to be the best embodiments of my invention. I do not wish, however, to be coniined to the embodiments shown, but what I desire to cover by Letters Patent is set forth in the appended claims.

I claim:
