p This invention relates to improvements in methods and in mechanism for delivering boards. i I
Although the device of my invention is not Wholly so restricted, still, it is primarily designed to accomplish certain definite pu'r- I poses and functions in onnection with and prelimina'r' to the production of a certa n product it 1Cl1 is, made up from materials havin characteristics requirin handlin oi the materials in a manner to compensate for the peculiar nature of the latter.
hly invention is especially designed for,
be hereinafter describ d and are dealt with l in the machine, as sets, and the sets of boar'ds are retained in assembled relation through out their passage through the machine.

Although certain operations on the sets of boards are intended to be performed w hile said sets are negotiatin thismaehine, which operations are not shown or descr bed,fb'ecause-they would he aggregative to this ma chine, still, my present invention hastedo with novel means forno't only maintaining predetermined segregation of the sets. of boards, but also, for ali ning the boards of the sets While they are segregated and preliminary to subsequent and further epera-' tions thereon With Which this case has nothing othervvi'se'to do. p
I will next describe one form of the device of my invention which I think is best adapted forthe foregoing specialized service, and will hereinafter particularly point out in the claims the specific features of noveltythereof. e

Like characters e'f reference designate similar parts throughout the. different fig ur'es of the dr wings. I i
In the form shown myinvention includes aboard alining tie, having 'fiat table body 1, provi'd'edi'vith a delivery en-"d "2 andhaving slots 3, therein. Below table 1 is a "cross head 'eem risih' longitudinal 111E151- bers 4e, slidable in .guic es 5, and connected \vith 'cr'oss braces 6. lit the rear end 7, of the table, the members 4, are connected with 'a bar 8, and a pitman'9, is pivotedat 10,
to said bar. The remaining end 1 1, of said pitman is pivoted to a. crank disc 12, mounted on the upper end of a shaft: 13, that 'is journalled in ahearihgie. O'n 'the lovver end of said shaft 13,= isa bevel gear 15 \vhi'ch meshes with bevel gear 1B, onfa. counter;
shaft 17, suitably j-eu rnalled i'ri'siippo i ting frame members 18 and'19. The remaining 1 end oi? shaft 17, has a sprocketWheel 20,?
over which chain 21 istrai'hed, said eaten loeing trained everepreehetwheel 22; mounted on a carrier shaft-23, which is suitably j u'rnalled in member-e18 and This carrier sh'aift may constitute the main; drive haft wherete power ma be applied in an desired wayat 24. Mounted on shaitee,
are ear ier sp ocket wheels "25 ended-over -which the intake laps v of ' endiess carrier chains 27 and 28, are: trained, and which endless carrier vvill hereinafter bejt'erhi 'd a-earrier, when broadly referred "to; 1 pro- 'vid'e U-shaped guide su ports 29 and 30 for the chains 27 and 28, i'espeetively, and on that side of the eer'rier-reme'te t eir the intake side 31, I provide aguide liner-32,
the bottom 33Xthereof, being preferably flush with the tops of su port guides 2'9 and 30. This guide liner adapted to enie ends of thebearde delivered e e y t onto the-carrier, as will be later deathbed.
On the intake side of the carrier designated as the intake side, and suitably disposed beyond the feeding rolls, to be later described,
is shifting-liner 33' having a bent shifting end 34 which is suitablyreduced in size Y and'arranged to project sufficiently between the rolls to engage the right hand ends of chains 27 and 28, respectively. Said follow- 40,,of the follower, projects sufficiently to er sare frecessed 317 37 .and 38,to clear the guides 29 and 3t), and;the central portions. of said followers are increased-in heighth-as indicated at 39, for a purposewhichwill presently appear. The normally upper edge engage the boards but is below the .tops
thereof, the followers being arranged to engage the boards laterally thereof.
Iqhave ,provided m'eans for lifting the foremost endsof the delivered boards to free them from interference with the guide 29 and chain, 27,v until after the delivered boards have been deposited onto the carrier. As shown, said means consists of a plate 41, having a downwardly curved end 42, to
escape the approaching followers. As shown iniFig. 6, the intake side of plate 41 is pivoted at 13, to any fixed part, and the other side is normally urged upwardly by means such asa spring 44. To limit upwardmovement of said plate, the latter is provided with a lug 45, adapted toengage the bottom of guide 30. As will be seen/in Fig. 6, the
foremost endLG, of the boardlfliselevated free from possible. engagement with guide v u I axes substantially parallel with the length r 29, as the board is being advanced in the direction of length, as will be later de-- scribed, y I will next revertto the board aliningtable. and describe the manner and means of .The table includes a front advancing thesets of boards from a pile or stack onto said carrier.
. which preferably extends across the delivery end -2, of.the table, with the lower edge 49 'suffieientlyelevated to permit of the thickest random thickness. board to freely pass beneath said plate.
Said plate may be adjust- ,iably anchored in any desired manner, asfor ztinstancei by means of straps 50 and $51, so
a "lateral positions on the table.
My improved table board feeding means, as shown, consists of a feeding bar 57, which is adapted to slide on top oftable 1, and which is suitably connected by screws or bolts 58,.through' slots 3, with members 41-, of the cross head, previously described." The crank disc 12, imparts a fixed stroke to feeder bar 57, in any event, and if longer boards than those shown at A, are to be fed, then the bar 57, is .adjust.ed ,rearwardly or to the right of Fig. '1, into any one of the holes 59, in members 4. Therefore, it will beseen that I have provided a reciprocating feeding mechanism including a feeding member having a reciprocating stroke of a fixed length, and adapted to be adjusted to alter its starting and stopping positions in accordance with the length of boards to be fed; Inasmuch as the bar 57, feedsthe boards A, from the bottom of the stack or pile, I will hereinafter refer to thelsame as an under-feeding meansor mechanism.
This underfeeding meansi is adapted to cooperate with aboard advancing mechanism, the function of the latter being quickly to advance a setof fed boards across and onto the carrier, heretofore described.
' My improved advancing means consists, as shown, of coacting feeding or advancing rolls 60 and 61,. which are shown disposed between the under-feeding means and the carrier, said rolls being disposed with their the upper lap of the fixed bearings 66 and 67, mounted on the.
machine frame, and between. these bearings is a pinion 68. On the outer end of said shaftG l, is a bevel gear 69, meshing with bevel gear 70, on shaft 71, journalled in bearing 72,1'ix'ed on the machine frame. On the lower end of shaft 71, is a bevel-gear 73,
" which" meshes with bevel gear 74- on shaft '75, mounted in bearings 76 and 77. A sprocket 78, is mounted on shaft 75, and a chain .79, is trained about sprocket 78, and a sprocket 80, the latter being mounted on drive shaft 23. Thus I have disclosed the mannerin which power is applied to posi- 7 stroke.
the yielding sections 92 retract, and then the rolls take advancing hold of the boards and because the surface speed of the rolls is in excess of the speed of travel of bar 57, there. can be no interference between the two feeding means as the faster operating rolls pull the boards away from bar 57 before the latter has completed its. feeding 7 As the lower set is advanced. from beneath the stack, the latter descends onto table 1, and bar 57, and the stop 55, will be adjusted into such position that retraction of bar 57, back to a startingposition, will not shift the board stack away from engagement with plate 48, and the bar 57, will be in the position shown in F 1, ready to feed another set of boards.
The rolls 60 and 61 rapidly advance the boards, or. rather a whole set of boards,
transversely of the carrier and into substantially the position shown by the board in Fig. .1. The plate .41, prevents interference of the front or foremost fed ends of the boards with guide 29, or chain 27, by lifting the forward ends of the boards slightly, as shown. The arrangement and timing are such that almost immediately after a set of .boards has beenadvanced across the carrier,
1 plate 41, the latter will be depressedby the edge 39, of the follower, thereby'allowing the set of'boards to rest on the support uides 29 and 30, and be advanced thereon by the follower.
At this point, it is desired to emphasize the very great importance of the change of direction of movement of the sets of boards fron'rthe direction imparted thereto by rolls 60 and 61, to the-direction imparted. by the carrier. I In the first place, the followers are spaced apart a slightly greater extent than the aggregate width of a set of boards so that the sets will not only be retained segregated, as they are advanced by the carrier, but so that they can be advanced. between groove formers for forming grooves in the ends of the boards, and subsequently. presenting said ends for entrance therein of tenoned cleats. Thus, it will be seen that the function of thecarrier is not merely to advance boards delivered to it, in a heltershelter manner, but in an orderly manner with the sets of boards intact, and one set in separated relation f om another set. I
I It will also be noted that the boards of the sets are in loose parallel relation when delivered by the rolls, onto the carrieiyhence,
by having the carrier travel in a direction substantially at right angles to the direction in which the sets of boards are fed onto and across the carrier, the followers of the latter, engaging the set laterally thereof, act to hold the boards in parallel relation, the
slight friction of the forward boards on the guides 29 and 30, being suflicient to hold the forward boards of the set, back in engage ment with the rear board engaged by the follower.
Now it is clear that the set of boards, at
this point, are in parallel relation, but as they have not reached the alining means,
the endsof the boards of the set, may'not into alined relation, the carrier advances the boards between devices for forming grooves in the ends of the boards, and later, nailing strips are inserted into the grooved ends, all of which is not herein shown, but is set forth to bring out the importance of themachine, as hereinbefore set forth.
It is believed that my invention will be fully understood from the foregoing description, and while I have herein shown and described one specific form ofmyinvention, I do notwish to be limited thereto except for such limitations as the claims'may im- 1.
