The patent granted to George W. Loggie,

referred to, describesa siding mill using a planer without the live, feed'ro'lls' 10',"and one which does not have an automatic, re saw feed'device, such as 29, nor the jointer l9,'nor the controllable bulkhead75,'76.

In operation Rough boardsare placed on the table of planer'9 and are 'automatically fed into thesame'bythe coopera tion of corrugated, live feed rolls 10 and inclined bulkhead 11; i

In passing through the planer the boards are either planed on both sides and both edges, or on both sides and one edge, as desired. l Vhen planed on one edge only, the rough edge is the one next to planer guide 14:. The following boards, in turn, projects each board into the board receiver and trip where the rear edge of the board bears on inclined ledge 17, its front edge bears against front guide 16 and it is prevented from turn ing over by top and rear guide plate 15. When a board has entirely passed beneath guide plate 15 and cleared the planer bed its front edge turns downward and it slides down on apron 18 and on to conveyer belts 22, with its rough edge foremost. Thence it proceeds beneath trimmer tables to table 28. From this table each board is taken by hand shoved forward flatwise and stood flatwise against standing rolls 30 with its rough edge bearing on live rolls 31 which rapidly carry it endwise into live, resaw rolls 46 while forcing it against rolls 30. It is then driven through the resaw, which saws it into two flat, beveled pieces of siding which must pass, while being sawn, between guides 53, 53 and guides 54, 55, and beneath rolls 57 while its lower edge is being planed by jointer head 50.

While passing over the jointer jamming sometimes occurs in guides 54, 55 due to broken fragments from damaged parts mov ing between the wedge-form surfaces of the siding or to the failure of damaged ends to properly abut and remain in line, thus passing to sidewise relation. and requiring more room transversely. The cause of the stopping resulting can be quickly removed in my ointer by lifting rolls 57 by hand when the guides beneath are accessible and the pressure is relieved by withdrawing guide 55. The wide, flaring grooves of downpresser rolls 57 allow for considerable increase in the width of the stream of stuff passing beneath them.

As fast as the strips of beveled siding pass on to table 60, 61 they are placed by hand on to conveyer belts 63 which move them .toward planer 9 and beneath trimmer tables 71. As they approach and leave each trimmer table they are accessible to the trimmer Sawyers who place them on to trimmer tables 70, trim their ends and saw them into a variety of standard lengths by using saws 69. 'ld rom jthis operation short pi ecespf trimmingsfall"directlyinto chutes 722L011 to conveyer belts beneath and are carried to the'furnaceroom for fuel. 'l cnger'pieces of trimmings are recuti'nto lengths no longer than about 18'1inches 'andare also thrown into said chutes. Piecesof damaged siding longer than this, say'f'about' four feet long, unsuited for the minimum."length of siding, are thrown" by handbackwn to 'conv'eyer belts 63 which carry them to controllable bulkhead 75, 76. Also, it not infrequently occurs that in passing through the several devices and machines a board is cracked from end to end, rendering it entirely unfit for siding. Such boards are not removed from belts 63 and are allowed to pass to bulkhead 75, 76. When an accumulation of these damaged strips appears on arms the trimmer sawyer near floor push 87 depresses it with his foot, moving it clownward as far as it will go. As drawn, this causes ratchet 81 to revolve the space of one of its eight teeth. Gear 79 has one fourth the diameter of gear 80, thus said turning of ratchet 81 causes gear 79 and arms 75 to make a one-half revolution, dumping the damaged strips on said arms into chute 89 and on to conveyer belt which carries them to a place where they are assorted and made into forms adapted for other uses.

Pawl 82 engaged with ratchet 81 prevents the weight of the damaged strips accumulating on arms 75 from turning the arms backward. While spring 95 bearing on a fiatside of square boss 94: prevents arms 75 from moving beyond their operative position by momentum when the bulkhead is being dumped by operating floor push 87.

As ordinarily operated the trimmer sawyers must reduce all pieces unsuited for siding to the short lengths of waste referred to. This requires valuable time of the most expert employees and results in using for fuel much material that can better be diverted to more valued uses.

I have employed chain-and-lug conveyers to replace the belts 22 to good advantage.

Having thus disclosed my invention, what I claim is new and desire to secure by Letters Patent is,

1. In a siding mill in combination, a beveled-siding board resaw, a wood jointer table at the delivery end of said resaw, a revoluble jointer head beneath said table, doWnpresser rolls mounted for revolution on axes parallel to the axis of said jointer head and on arms hingedly mounted on brackets above said table, stops whereby the downward movement of said downpresser arms are limited, a back guide over said jointer head and beneath said downpressers, a spring-pressed guide bar movable through parallel positions with and in front of said.

back ide, and a siding oonveyer operable at rig 1t angles to said jointer and from the delivery end of the same.

2. Ina siding jointer in combination, a 5 joinber table, a revoluble jointer head mounted for revolution beneath said table, a back guide fixed on said table transversely of the axis of said jointer head and above the same, a front-bar guide mounted on 'downpresser arms. 10 spring-pressed pivoted arms for movement away from and parallel With said back guide against the reaction of said springs, and two downpresser rolls each having a deep flaring annular groove mounted for revolution in a line parallel with and above said guides, on arms hingedly mounted on brackets above said table, and adjustable stops adapted to limit the downward movements of said ARTHUR sonENK.
