' Specification of Letters Patent.

Application filed October 29, 1919. S eria1 No.,334,155.

To. all whom it may concern;

Be it known that I, JOEL S. JUNKIN, a citizen of the United States, residing at Kennedy, Route No. 3, in the county of Pickens and State of Alabama, have invented .certain new and useful Improvements in I Saw-mill Attachments, of which the follow- 7 .between the members 4 and 5, 0f the supingis a specification. This invention'relates toattachments for saw1. mills, -and the object thereof is to providea simple and eflicient apparatus to be View, which will'appear as bination and located between the carriage track and the live 'rollersin position for tripping the lumher from the saw on to said live rollers and prevent all danger of the lumber falling A .andpatching' on the saw, thus damaglng; I

/ port 3, being held against lateralmovement the mechanism and injuring the operator.

Another object is to With the foregoing and other objects in proceeds, the invention resides in'the comthe details of construction hereinafter. described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may, be made within the scope of What is claimed without departing from the spirit of the invention.

In the accompanying drawlngsz Figure 1 represents a side elevation of the attachment constituting this invention with the trips shown lowered in full lines and raised in dottedlines, I

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1,

Fig. 3 is a central vertical section taken on the line 3-3 of Fig. 1,

Fig. 4 is a detail vertical section taken on the line i4of Fig. 1, and 7 Fig. 5 is a detail horizontal section taken on the line 5 5 of Fig. 1.

In the embodiment illustrated, the attachment constituting this invention is shown mounted on two cross bars or bases rovide an attach- .mentof this character which will effect great a saving in time and labor and effectually pre- 1 the description H arrangement of parts and in feet6 which are secured to the bases'l and 2.

distance beyond'the legs of saidlsupport having fixed thereby and rising therefrom, .nprights 8, 9 and 10. I The uprights 8 and 10. are secured: to the endsof the bar 7,

while the upright 9 is "secured to said bar midway its length and passes upward be.

tween the two members 4 and 5. of the supby bolts or rivets. 12 positioned on opposite sidesof said upright. 7 Each of'these uprights 8, 9 and 10 is provided at its'iupper end with a loop-shaped trip member 11, allof which are positioned in" the same plane as is shown clearly in bar 13 is bolted'to the support 3 near its upper end as shown at 14, said bar being positioned on the outer face of the member 5 of said support. This bar 13 has outwardly and upwardly inclined arms 15 and 16 which carry at their free ends laterally extending blocks riveted or otherwise secured to the inner face of said arms, said blocks being recessed on their inner faces to provide, guides for the uprights 8 and 10.

Fixed to and rising from the bar 7 are two standards 18 and 19 spaced inwardly from the uprights 8 and 10 and positioned outside the support 3. These standards are each composed of two bars 20 and 21 which straddle the bar 7 and have mounted between their upper ends, one end-of levers 22 and 23 which are pivotally connected and 26v with an actuating lever 27 fulcrumed V (same.

at one end between the members 4 and 5 of the support 3 at one side thereof near its bottom. The lever 27 is offset laterally as shown at 29 opposite the upright 9 to position it properly to receive the lower ends of the links and 26 and prevent their interference with the movement of said upright and also to prevent its interference with the ends of levers 22 and 23. The actuating lever 27 has its free end positioned between the members 4; and ,5 of the lurr d and be w h bars 2 an 2. of the standard 19 and is provided at its terminal with a laterally extending pedal 30 which is designed to be operated by the With reference to Figure 3, it will be seen that the invention is adapted to be positioned between the carriage and the live lumber formed by the saw, so that the cut slab or board may be directed onto the live frolljersby the trips to prevent the cut slab from-falling onto the saw and damaging the F'om the above description it will be obviousthat the weight ,of'the' bar 7 and the pants carried thereby will normally' hold said barin lowered position as shown in full lines in Fig. 1. .When it is desired-to elevate jsjaid b'ar to'project thev trip members 11 into operative position for engaging the lumber and passing it to the live rollers, all that is necessaryis to depress theifree .end of the Lever-:27, preferably by placing the foot on the pedal 30; TWhen this lever isdepressed, the'l'inks 25 and26-will be-drawn downward, thereby lowering the innerends of the le- 'v'ers 2 2. and 23 and elevating their outer ends,thuscausing the bar 7 to be lifted and the uprights 8, 9 and 10 carried thereby to be moved upwardly projecting their trips ll into operative position as shown in dotted lines in 1. The support .3 has apertures 31 extending "through the leg between the members of which the lever- 27 is guided to provide for the reversal of said lever when the attachment is to be used with a left hand saw, it being obvious, all that is necessary for this is to remove the fulcrum 28, turn the lever around, and position said fulcrum in the apertures 31.

T From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of .the invention together with the device which I now; consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are with v in the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to severtical movement on said support, a plurality of trips mounted upon said horlzontalbar to extend upwardly therefrom, levers fulcrumed intermediately of their endson said support, standards rising from said bar to which said levers are pivoted at. their outer ends, and links connecting "the-inner ends ofsaid levers with said actuating lever in advance of its fulcrum.

2.11 slab tripping mechanism comprising a support, ahorizontally disposed bar mounted for vertical movement insaid support', uprights fixed toand" rising from said bar and having trips at their upperends, arms extending in opposite directions from said support in which said uprights are--- guide d, alever'fulcrumed at on'elend on said support, and a link and leverconneetion between said -first -mentioned lever and said horizontal bar whereby'the lov'veringof said first-mentioned lever will operate to raise.- w

said bar and'position said trips in operative position. v

'3. A slab tripping mechanismcompri'sing an inverted U shaped support composed of laterally spaced members, a horizontal bar mounted between said members for-vertical movement, uprights rising from said bar and'provided at their upper ends withtrip members, guides forfsaid' uprights, levers fulcrumed intermediately of their ends be- 5 tween the members of said inverted U- shaped support, standards rising'from'said horizontal bar and fixed thereto, said levers being pivoted at their outer ends to said standards, .a reversible actuating lever fulcrumed at one end to'one leg of said support and extending between the members of the other leg whereby it is guided in its vertical movement, and links connecting the inner ends of. said levers with said actuating lever. i

4. A slab tripping mechanism comprising a supporting base, an inverted U-shaped support fixed thereto and composed of laterally spaced connected members, a horizontally disposed bar mounted for vertical movement between said members, upstanding trips carried by said bar, levers ful-1 fulcrumed at one end to one leg of said support and having an ofi'set portion, guides for said lever, and links connecting the offset portion of said actuating lever with the inner ends of the other levers.

5. The combination with a log track and saw; of wedge means arranged along the track and projectable vertically to enter the cut in the timber made by the saw to trip the slab cut.

6. The combination with a log track and saw; of a plurality of wedges spaced longitudinally of the track, a bar connecting said wedges, and lever means for moving the bar vertically to project the wedges 1 JOEL S. J UNKIN Witnesses:
