To all whom t may concern Be it known that L HERBERT M. LorToN,`

a citizen` of the United States, and resident of the city of Atlanta,` county of Fulton,

" State of Georgia,have inventedan Improvewhich is serially numbered l.l17," 07 and `tiled February 24th, 1908 `and lismore particu-` larly directed to giving to the machine therein set out further `capacity `whereby it may also be `used for sawinglaths.l

`More generally considered,vthe object of `my invention is to provide a construction of machine` capable of doingcertain combina tions of; work from; one` saw` `mandrel emv ployed with" one carriage and `one main frame;` and among the kinds of Work to be done are sawing of shingles, laths vand ordrnary roughmgout work7` preliminary to the sawingof the shingles and laths. l

My inventionconsists of the features of construction whichare described in the specifcaticn hereinafterzand more particularly pointed out in the claims.

My invention will be better understood by referenceto the drawings in which Figure 1 is a planz View of` my improved machine; Fig. 2 zis an enlarged plan view of the `carriage portionof lthe machine; Fig is a sectional elevation of azport-ionof ithe machine, having `particularreference to the automatic tripping devices `for reversingthe movement of the table or carriage; Fig 4 is a cross section of the machine on line -eof l Figf is atplan view of the center beam and detachable lath table; Fig. 16 is a Fig. 1;

sidelelevation of the lath holdingpawl devices; and Fig 7 is a plan `View of the saw arbor' and end of the mandrel@ 2 is the main frame and may `be of any construction desired and is provided with guides, 3 at the top `upon whichthe rei {ciprocating table (i travels. Suspendedfrom table Gare the drop brackets `8 which at `55l either end` support the friction board 7. These brackets also support and have made fast to them the rod 17 this rodin turn carries adjustable collars 16 clamped at 18,\the springs 20 and the buffer collars 21.` Collars 60 16 also have the lugs which in turn carry the `tappet rods 15. These tappet rods areadjustable and; are held in place by means ofi the set screws 19.

24, `24:` laretwo swinging brackets hung651 from the transverse shaft 23 and carry the two shafts 29` and 30, provided respectively y with the friction `wheels 27 and 28, which are `'closeto the frictionboard 7 The shaft 23` 1s provided with a band wheel 31, whichis 70` driven by a belt 32passing about a pulley 33 secured `tot the `mandrel 4,` which latter ;is journaledon the lmain frame 2 and has the saw arbor and saw` 5 at one end and the driv` ing belt pulley 34 at theother` end. The 75 shaft 23is geared to the shaft 29 by gearing 35 by `which the table 6 isfed backward withl y i l a quick speed. Shaft 29 is geared to shaft 30 by :gearing 36, whereb the speed of shaft 30 is caused tobe greatly shaft 29 and is employed tol advance the 1 table slowly.` By this means the table is adi vanced slowly as when sawing and returned quickly when performing no act of sawing. Either 10ft the friction wheels 27 01228 may `85 i be thrown into contact with the friction l board 7 by oscillating the swinging brackets y 24,; and as said frict-ionwheels are rotating in opposite directions it is evident that `the tablel will be propelled forward or back- `90 u ward as the casemay be.` u Moreover, as the u roller 2T is rotatingfaster.V than the roller 28,` thetable will bepropellcd backward faster than it ispropelled forward inthe act of sawing.

One of ithe brackets `24: is provided with two lugs 25 between which is placed a `cam 26 secured toa rock shaft 10 journaled in fixed bearings on` the main frame.` The front endof the rocklshaft 10 is provided 100 with an arm 11 whichmayibe extended up-1 ward lby a detachable handle 11` `(`I*`ig.4=)` l and said arm provided `with a `pin 12; and the rear end ofthe rockshaftlO is prod videdwith a weightedarm whichthrows 105 t less than that of 1 When the shaft rocked to the position shown in Fig. 3 the friction wheel 28 is operating `upon the board 7 and the table 'is being fedtofthe left, as in the `act of sawging. `The pin 12fon'the arm'11 is caught back of a locking pawl13 and holds the c lr-ller-28 vtoits workjuntil the `tappet 15,'.

V moving withthev table, strikes they arm 14 on the shaft 22 of the pawl 13, causing it to be tripped and the pin 12 released. At the same time, the buffer collar 21, pressing v against'the end ofthe arm 35 extending up- Wrdfrom thecam 26, is forced forward by the compressed spring ,and throws the said :arm over afver'tical 'line through the shaft'-lO, with the result that shaft l10 is rocked vandthe"brackets 24 so shiftedas I Y rto throw wheel' 28 out of contact and wheel A' Y.. 27 into' .contact withy the lfriction bo-ard '7.

Whenzthe arm 11 is thrown over lwith shaft Y 10, thepin12 thereof locks into a second pawl 13 ,upon the opposite side of the rock shaft 10.l The table will no-w be drawn lbackward by the yaction Iof the wheel 27.

,These 'operations are repeated automatically and regularly. The time -ofreversing,' tol secure along'or, short travel ofthe table,

, may be adjustedby` adjusting the tripping tappets'lv'in properpositions, which may be done by adjusting .them onV the collars 16 or adjusting the collars themselves upon the! rodi 17;` The'V co-unter vweight 55' acts Vto throw the rock shaft over until the` pin 12 locked by the pawl'13 and the friction wheel yengages the friction board,v once the collar v21has forcedthearm 11 and its pin rbeyond a Vvertical jposition.y In orderto stop the automatic movement of the/table, itis only necessary to raise one of the catch `pawls y13, Vand put the arm 11 in a central position. Whenthe arm is thus in a central position, neither ofthe friction rolls are in contactwith the friction board. Bythrowing the catch pawls 13 back out of the way andinserting the detachable handle 11a, the

movement of the table can be controlled by hand by oscillatingthe handle from one side to` the other toy alternately bringeither of the frictionrolls 27 or28 intodriving contact withthe frictionboard. The table can be given any lengthfof stroke by adjusting the collars 16 on the rod 17'to-the desired position. These collars 1,6 are made fast to thev rod by meansy of the adjustinghset :screws 18. y j

In operation, it is necessary that the cam*` 26`should be thrown over with just the right force, and I accomplish this by having lthe v tappeti-rods 151adjustable inthe collars 16. `As' previouslystated, these tappetrods yare made' fast by meansof thesetscrews 19.

This featurefof regulating the force with which the cam'26 is thrown Iover isvaccom- Yplished in this way: Thev table in moving,

lwill'compress the spring120 by the collar 21 being arrested by contactv with arm,3;5,and

the point at which this* spring is released is regulated absolutely by adjusting the tap-y pet rods 15 so that they will release the springs at any desired point of compression. I will nowrefer'to the construction and operation of the clogging device onfthe table.

' Thedogging plate 44 yis let down into the table 6 flush with its upper surface and this plate has aseries of hole's45 drilledwhich in turn carry a removable table 6 lalso has the endz board 6a. This board carries the steel plate-T-with'a series of teeth: on its forward edge. The plate 457 has the `slots't() through which bolts61ex tend and by which the plateis guided with a parallellmovement.` Movement,y is im.,n f

parted to this clogging plate 57 4by thehandle 59 and toggle levers 58.- I y Infdogging a piece of timber 'itl will be means of` placed on the table 6 with onevend near the clogging plate 57." The pin 46a-#would then be placed in one of the'holes 45 in the plate 44 as near to the forward end'of theftimber as possible. By pulling the handle'59,v the plate 57is moved forward and its teeth are pushed against the end of the timber, which" in turn is pressed against the pin 'carried'.

by the plate 44. A still further movement of theh'andle 59 willf'insert theteeth'and hold the timber firmly.`

Thesetting plates 47v are embedded in the table so that their upper surfaces-'come flush with the table. drilled in these plates and they setting pins A series of ,holes 49'are i 48 are inserted iny holes kof the respectiveL 1 plates suitable to the thickness of board thatfp l it is desired to saw. `The timber'isfthen pushed against these pins 48 at'the end of each stroke, thus making the timber ready for a new cut. y

yThe features of the` doggingdevice, and

the setting `pins have reference to the com# machine in that they'will operate to `holdy a bination lath and shinglefeature's of ythe round log, for'instance,zwhile the necessary 5 thickness of shingle bolts orlath strips j are being sawed preparatory tofresawing into shingles or laths, asthe case mightbe;

value in sawing v,any other forms of material."

As this is a combination sawingmachine Q ,y

it is necessary,l in adapt-ing itto various classes of sawing, tochange the saws 5 from time to` time on the mandrel "4. Thus, in f' usedy for holding the large sawinstead of several thin collars, as would ber the casein sawing laths. Likewise, the `long collar shown in Fig. 7 wouldbe usedat all times when just one sawwas; on fthe mandrel.

The lath clamping ydevices 50,`shown more 5` particularly in Figi 6, consistof a1series of` vertical `fixed plates, 53, between which are hinged the eccentricholdingpawls 54, and betweenwhich` pawls and the lath `table 51 the laths are fed `and gripped after leavingi the saws 5.

To insure the lath strips being sawed into straight laths I providehinged fingers 39 on the table 6 for ipressingthelath strip against the edge 631of the opening ini the said table,as more fully described laterzon.` I will now describe the operation ofthe. machine in sawinglaths: The first thing to be done` is `to` i'emoveathe detachable board; 56, as shown in; Fig.` 2;and theni place `the several lath saws in position on the mandrel, as shown in Figal andindicated at 5. Then, by moving the` table 6 to the right `as far as it will go, thedetachable lath tables `36 can be placed `in `position `by inserting the` `brackets 37 in the sockets 37. The table is then put in motion` in theiusual` way `and when it makes its extreme back stroke, the strip from which itis intended to make laths is dropped 1into` 1 position oni n top of the lath table 36, whichplaces this lath strip in the opening made ;by removingthe` detachable board 56. Aforward strokeiof the table `6 then will cause the lath strip to .slide along on top `of the lath `tables and be forced upon the several lathsaws which will rip it up into laths, and after the table `has completed its forward stroke, the holding l pawls 54 will automaticallygripthe respective laths and `hold them `until another strip is put in and advanced,.which will .forcethel previously sawed` lathsiout lover the front end of the detachable table 51. This operation is continued as each strip is sawediinto laths. As the lath strip1is dropped into the opening previouslymentioned and the table 6 feeds forward,it is necessary to have this strip pressed in against the back side `ofi the opening indicated at 63 (Fig 2). This in-1 sures the sawingiof` straight aths I accomf plish this by means of the pressingngers 39 which, immediately after `the carriage starts on its forward stroke, automatically press the `lath strips against the backl side 63 of the opening and continue toiexert this pressure against the strip until each successive linger approaches the saws, at wvhich time these fingers automatically recede from out of the way of` the saws. 1 On the extreme i back stroke these `fingers also recede iiniorder thatithe lath strip `may be placed `in the opening. The movement of` theseiingers in and out is controlled by meansl of the `xed cams 38 and 389, as' indicated; in Figs. `2 and 5. y

`It will be seen from Fig, Q that the fingers 39 are pivoted to suitable brackets on;

the table 6. i These fingers have rollers indi` cated at li0 traveling against the cam 38. Al rod/f1 has `springs 42 pressingyupon the heels of `the fingers 39 `to press them toward the guide edge 63. The rod is carried by the table and at its front` orright end connects i with the `bell crank 43 whichlhas a roller iat its `free end acted upon by the cam 38% It will thus be seen that onthe forward stroke of the table the roller 40 on each pressing; finger `39 is brought into contact with tht` i cam 38 which causes it to recede, independently of any of the `other fingers, out of the way of the saws, and this is the case as each successive finger approaches `the saws.

` In viewof itheconnectingrod being con` nected to all of the` fingers andalso connected tothe bell crank 15,.it will beseen that, on its extreme backward stroke,` it comes in contact with: the cam 38, thus causing all of the fingers to simultaneously recede, `in order that theilath stripmay be dropped into the` opening preparatory for being sawed.`

I haveshown my invention in the form which I have found most excellent in com- `mercial use, and while I prefer the construction as shown, I do not restrict myself to the details, as these maybe modified in various ways without departing from the spirit of` the invention.`

It will be understood that in `order toiuse a larger saw for bolting and otherwork, ;it` will beinecessary to lift the lath tables 86 and 5l out of iposition and also `to replace the detachable board 56 which` can be` done by putting `the table 2bn its extreme back stroke, thus automaticallypulling the pressing fingers in their housing underneath the` table 2, which will permit the board 56 to be placed in position.
