Application filed May 3,1926, Serial no 105,528.
My'invention concerns certain features of novelty and advantage in the stock-feeding mechanism of wood-working [machines and vpertains more'particularly, but not necessarily. restrictedly', to appliances of this character associated with, or forming parts of, end-matching machines, ,i p 1 One of the leading aims orpu'rposesof the the invention is theprovision of afconstructionof this character'which willreverse the operation of the feedingmeans to back out an improperly advancedfpiece of stock and at the proper time feed the board into the machine'again by restoring the normal ac- 1 tion of the feeding mechanism, this reversal action continuing until the stock passes through or is removed from the machine,
' The invention, as presented in this application, is depicted in connection with beltdriving means for'the machine, but nothing more than ordinary, mechanical skill would be involved in adapting the principles hereinset forth to a direct motor drive.
To enable those skilled in this art to have ,a fulland complete understanding of the invention and itsvar'ious advantages, in the accompanying drawings, forming a part of this specification, and throughout the'several views of which like reference characters have been used to designate the same parts, I haveillustrated a present desirable and preferred embodiment of the invention.
In these drawings: a
Figure 1 is an elevation of the machine;
7 Figure 2 is an elevation of the machineat right angles to that of Figure 1;
v. Figure 3 is an enlarged horizontal section on line 3-3 of Figure 2; ,and t Figure 4 is adetailview of a portion of 'themechanisml, ;f a. I r As is shown,'t-he improved machine comprises a suitable and appropriate frame 11 of the irregular form shown in the drawings, 's'uch frame adjustably supporting an elec- Another motor 14, likewise. adjustably I supportedjon theframe, rotates ayout-of? saw 15, as is usual in constructions of this character. I, v I
the machine In'thus passing. through the machine, the
frame.
The stoclris fed or advanced through the machine by an endless chain conveyor 16 ex-' tended around suitable sprocketwheels 17 I Sprocket-wheel l7 ismounted on and rotatable with an appropriately journaled shaft 21 operativelyconnected by reduction gearing 22 in an enclosing casing 23 to an- 25 and 26ga'nd two loose pulleys 27 and 28:.
Such pulleys are connected to fanelongated drum or pulley 29 driven by an electrio-motor 31 by a ,straight-belt-32 and a crossed-belt 33. V
described hereinafter.
on the links of the conveyor chain 16 and are provided forthe purpose of pushing the stock accommodated therebetween' through so that thesaws or. cutters may act thereon; a
boards travel below an upper, horizontal guide pr hold-down member 35 which may, 11: desired, be vertically adjustable on the A presser-b'ar 36, having a front rounded nose 37,"is fulcrumed at38 on the member 35, and it is'pressed or forced down by a deaf-spring 39, a suitable stop or abutment be ng provided to limit or restrict its descent, 'sothat in its lowermost position, its under fsur-f'ace' will be in approximate register with the bottom face of thehold-down member '35 as depicted inFigure 2."
Two pairs of bearings tl and 42 on the jmember .35 accommodate a pair of spaced, i parallel, slide- rods 13, 13 and to each ofthese 1 there is secured a detector thaving a screw 'andslot connection 15 with the part 35.
trio-motor 12 which actuat'es or rotates the 2 Each such reciprocatoryrod or shaft 'is supplied-With a collar :46 fixed thereto andhaving an inwardly-projecting pin 17,

operating-handle 52 by means "of which it v ,A coil, contractile sprlng I fastened to fthe'lever and tends to rock its upper'portion to the right asthe parts are viewed in A link 54, adjustable as to length, conn ts the, p par of lever 4 .9 to a ann secured .;to the upper ellQliQ-fjax 6I'tlCZUllyllS posed, appropriately-journaled rock-shaft 5b, the lower end of which-is equippedwith an offset or bent arm 57 strengthened by a. rib '50, the bottom end of-arm 57 being piv otally connected to one endof a link 58, the opposite end 'of which is forked to receives lateral pin" 59. on the lower end of'a lever 61 fulcrumed at 62, a contractile spring 63, fastened t the lever, and to a clip GgLinounted on thewlink, affording a certain am-ountof yield or flexibility tothe pivotal connection between the, elements.
Theforked, upper end of lever 61 coacts witha-cross pin 65 ofa collar fastened to a rod or shaft- 66' slidable inhearings 67 and 68, such rod carrying two pairs of belt-sl'liftingarms 69, 69- and 71, 71 onopposite sides of the two belts .and adaptedyto simultaneously shift them in either direction by enagagement with their edges, all aslwill be detector-block or blocks 1n the same direction as its inward feed, thereby rocking lever 49 against the action ofspring 5.3, and, through the ' connectedparts 54, 5, 56, 57,
58,61, 69 and 70 cause a shifting ofbelt 32 from the tight pulley to the next loose pulley 27 and of belt 33 from the loose puley 2 15 the adj cent tight pul ey 6,1 1 h action, ofcourse, effects areverse feed of the conveyor-chain 1 and the piece ofstock producingthe trouble.
As soon, however, as suchpieceof board, dur ng suchbackwardtravel, releases, the
detector member or members, as the'case may be, the contraction ofspringb? returns all of'the parts to original position, thus reestablishing' the forwar'dfeed of the conveyor chain and the piece ofjstock.
If such piece of stock, in the meantime,
' has become properly positioned, it willbe now 'carried through the machine in the usual way, but, ifiit is still ,improperlyor incorrectly positioned, it will again strike the detector block or'blocks and cause a repetition of the preceding action, and such feed reversals willcontinu e automatically until the piece of stock rights itself appropriately or isremoved'from the machine, whereupon the-normal operation of the mechanism is automatically and quickly restored.
Stated somewhat differently, the ;.inachine mak s a series o attemptsto fee heincorreotly-positioned board through it, but it w-illnot carry itj -threugh until it becomes properly positioned for that action.
' Ataiiy time, the-workman may cause'a. re-
verse operation of the feeding mechanisnrby merely pulling handle 52, and as'soonaas it is released, the regular or ordinary forward feedis restored. V It will benoted that the pressure-arnr36 extends' forwardly beyond the front ends of the detector blocks, and, if it is able to hold theboard de wmso that itwill'not engage and. actuate the detector blocks, then" the board will pass through ,themachine without djilfijculty, but, if it cannot maintain the board depressed it will yield upwar dly and permit the board to strike the detector blocks and cause the peculiar recur-rent reversal feeding action described. 7
Those acquainted with this art will readily understand that the invention is not limited and] confined to the particular details of structure shown and that these may be modilied within comparatively radical limits without departure,- from the heart and essence oftheinvention andwithout the sac.-. rifice of any ofits material benefitsior'adivantages.
