COMBINED WOOD SAWING AND SPLITTING IVIACIIINIEI.l

Application filed June 15, 1923. Serial No. 645,611.

The invention relates to improvements in combinedwood sawing and splitting machines and an object of the invention is to provide a power driven machine for sawing wood poles into blocks and subsequently chopping or splitting the blocks, there being suiiicient chopping capacity to conveniently handle al] the blocks 'cut by the saw.

A further object is to provide a machine wherein the handling of the wood is reduced to a minimum, the eut sticks or blocks being passed from the saw to a position adjoining the chopping blocks by a conveyor.

A further object is to arrange the driving mechanism such that both the saw and the axes can be driven by aV single source of power, such as an internal combustion engine mounted on the machine or by a portable engine adjacent the machine.

A still further object of the invention is to provide a feed table or carriage for supporting one end of the pole to be sawn and which is` arranged such that it will automatically'feed the pole to the saw and such that no pinching of the saw in the cut can occur.

A further object of the invention is to provide a combined sawing and chopping machine, the frame of which is arranged such that it can be mounted on trucks, sleighs, skids, or other desired mounting.

Vith the above more important objects in view the invention consists essentially in the arrangement and construct-ion of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which:

Fig. 1 is a side view of the complete machine as it appears mounted on a truck body.

Fig. 2 is a plan view of the same.

Fig. 3 is a vertical sectional view longitudinally through the machine, the section being taken at 3 3 Fig. 2.

Fig. 4 is a vertical cross sectional View at 4-4 Fig. 3.

Fig. 5 is a vertical cross sectional view vat 5-5 Fig. 3.

Fig. 6 is a side view of the feed table or carriage and parts associated therewith.

Fig. 7 is a vertical cross sectional view at 7 7 Fig. 6.

Fig. 8 is a perspective view of one of the p splitting axes.

In the drawing like characters of reference indicate corresponding parts in the several figures.

The machine can be mounted in any suitable manner for transporting purposes and in the present instance is shown as mounted on a truck frame embodying the front and rear axles 1 and 2, wheels 3, front and rear bolsters 4 and 5 and thereach G connecting the axles. This truck frame is 0f the ordinary wagon type and further details thereof are not considered necessary.

The sawing machine frame 7, which is substantially rectangular, comprises a pair of similar side beams 3 and 9 connected rearwardly by a pair of spaced cross beams 10 and 11 and forwardly by a platform 12, the platform supporting a source of power, such as an interna-l combustion 13. The frame 7 is designed such that it can be seated on the bolsters of the truck frame, the beams 1() and 11 receiving the rear bolster therebetween, whilst the forward ends of the beams 3 and 9 are received between pins 14 and 15 carried by the front bolster. These pins prevent lateral shifting of the forward end of the frame 7 and the beams 10 and 11 prevent end shifting. The frame 7 is fastened to the rear bolster by pins 16 extending upwardly from the bolster into the beams S and 9.

By the above arrangen'ient it is a very easy matter for one to dis'mount the machine from the truck frame and put it on any other type of frame, such as sleighs, skids, or such like.

The engine drive shaft 17 is provided with a pulley 18 which carries a belt 19 operative over a further pulley 2O located on a counter shaft 21 carried in suitable bearings 22 mounted on the beams 8 and 9. Iil'imediately to the inner side of the beam S and on the counter shaft I mount a wood cutting saw 23 which is of the ordinary type', and to the opposite end of the counter shaft I secure a combined balance and fly wheel 24 with which I associate a comparatively small pulley 25, Thesaw is in` this way driven directly from the engine and rota-tes in the direction indicated by the applied arrow, Figure 3.

Adjoining the outer face' of the beam 8 I locate a short beam 26 which is spaced from Lthe main beam to provide a vertical slot 27.

A carriage or feed table 28 is supplied for supporting the end of the. stick or pole to be sawn. This carriage'in the' present instance is in the form of a substantially reetangular metallic plate fitted with

upstanding end flanges

29 and 30,A each-'flange being cut t provide a. V-shaped recess 3l.

The plate is also'supplied on the underside' with a centrally positioned tin like extension 82 which is slidably receivedwithin the slot 27. The p carriage is 'supported for swinging movement towards and away from the saw by a pair of hangers 33 andY 34 which have theirlower ends pivotally secured at 35 to the front land rear ends Aof thevcarriage andtheir upper ends pivotally secured by bo-lts 36 to bearings 37Hperma nently mounted. on the outer of a vpair' of elevated beamsSS and 39. A coiled spring connects one of the hangers to the beam 38 and 'acts to hold the carriage .normally in its back position or withdrawny from the saw. Theends'of the slot limit the forwardland backmovement of the carriage and the spring is gauged such that it will draw the unloaded carriage backrkbut is not strong' enough' to prevent the carriage movingahead under the added weight ofthe vpole or stick of wood, the endof whichis rested on the carriage andl in the notches 31 when the same is to be c-ut.

By observing the position of the carriage sbownjin the drawings it will be seen that upon one end of the wooden pole being placed on the carriage the added weight willcause .the carriage to swing ahead towards the saw and against the action of the spring and in so doing automatically feed the pole to the saw by which itis cut. In

this lconnection it is to bev understood that one end of the pole to be sawn is rested on the-carriage and the other end is held up by the attendant. fis soon as the cut is made by thel saw the attendant relievesv the carriage ofa goodly portion of the weight of the unsawn part of the pole and the carriage automatically returns to its original vposition under the influence of the spring. 'lfheattendant also-,advances thevpole the proper distance Vfor the nextcut and upon lettirge; the weight of the pole come again onto the carriage the following cut is made in the same manner as the. first out, the carriage advancing to the'saw.

`vletween the side beams of the frame 7 I locate an endless conveyor 4l which is formed from similar endless chains 42 operating over Vsimilar chain wheels 43 mounted on conveyor shafts 44 and 45 suit- .ablyjcarriedrin bearings provided on the beams 8 and 9. The chains'areconnected Aby suitably spaced cross slats 46 Yand the upper lsides of the chains operate over a cross plate47 interposed between the beams and supported thereby. The plate is out iirecting rods 75l and 76;l

standing' flange 48. This conveyor, which is driven ,as later described, is adapted to catch the shortsticks'cut bythe saw and carry .them rearwardlyto the end of the machine where they are 'thrown ofi' onto a pan 49 suitably` supportedl from the rear end of the fran1e7;f3A i n A transmission shaft 50 is located'rearwardly of the machine, being carried by suitablebearings 5l secured to the under sides ofthe beams Sand -9 This shaft is driven from they saw shaft 21v by ya belt 52 connecting the pulley 25 ywith, a pulley 53 on the transmissionl shaft. 1f w. f

VfIhe transmission shaft drives the conivieyor, such being Aaccompljish'ed by an endless chain 54 imn'iediately'at'the inner side of the :beam 9 and operating onchain wheels 55 andA 56 secured to the transmission shaft andthe forward conveyor shaft respectively. Atthe. rear end of the platform I locate a crank vshaft 57 whichfisiitted with two oppositelydisposed cranks 58and 59 and is carriedbyj pairs of end bearings (i0 andl suitably mounted onplates 6,2' carriedby'the beams 8 and 9. The crank shaftqisfitted at the, end with comparatively large fly wheelsGS andy 34 and thefly wheel v 63 is connected to the adjacent @endpftl'ie transirrission shaft byr a belt which operatesfon a flanged pulley 66 seeured'to the transmis sionL shaft. l s ,i

Therbeams 38 and 39 .arespaced apart and". are duplicated at the opposite sider 0f the vmachine. and they are supported at thenends by yupright rposts A67' yand A168. Brace beams 69 yand 70 extend ybetween the opposing posts at oppositesides oftheframe. Between thepairs of beams SSUandv 39 I mountv similar rocker'beams 71 and 727 these being pivotally :carried by, pivot pins 73 mounted on the'` top sides of the

beams

38 and 39 and fastened tothe rocker beams by suitable ,straps 74. The forward ends of the rocker beams which it Awill be observedl overhang the cranks of the crank shaft are respectively connected tothe cranks by .-.con-

The'rear ends of the rocke'beams carry Asimilar splittinga'xes :77;and 78 whiclrhave their cutting edges down and the arrangement is such that in the rotation of the crank shaft the axes alternately raise and lower to chop andwithdraw from ,the cut.' TheQaXes are f guided between extending pairs of Lbrackets `79 andSO permanentlyfsecured to the reariposts and the

beams

38 and 39. In

.this connection I ,might mention that the upper ends of the posts arearranged to guide the rocker beams so that no lateral spo ' play of the axes is permitted. The axes operate directly Vabove similar chopping blocks 81 and 82, these blocks being comparatively heavy metallic plates carried by the rear ends of the beams 8 and 9 and amply reinforced underneath. It will be observed that the upper faces of the blocks are checkered or otherwise roughened, such preventing the base of the block from side slipping, as might occur if the end of the block were cut at an incline. It will also be noticed that the chopping blocks are located immediately to the side of the rear end of the conveyor and also within convenient range of the pan 19.

Various parts of the machine can be reinforced by metallic straps or braces as occasion demands.

The platform 12 is preferably demountably connected to the beams so that it can be removed if desired. Obviously one might have a small t-ractor or portable engine which he wished to use instead of the engine 13. Accordingly, by dismounting the engine 13 and platform 12 one would be enabled to connect the portable engine to the driving pulley 20.

IVhen sticks or poles of wood are to be sawn, one person would manipulate the poles to feed them to the saw and two other persons would stand to the rear of the chopping block and take the cut sticks and present them to the axes. As before explained, the carriage would advance the pole to the saw without any effort on the part of the attendant other than the holding up of the free end of the pole and the raising and end shifting' of it to make the further cut. The short sticks cut by the saw falling onto the conveyor are carried back and thrown onto the pan where they are picked off by the other two attendants, placed on end on the blocks 81 and 82 and subsequently split by the down coming axes. The split sticks can then be thrown into piles by the attendant.

Obviously, the machine has a considerable cutting and chopping capacity and all unnecessary handling of the wood is dispensed with. The two axes will readily handle everything cut by the saw so that no time is lost.

What I claim as my invention is:

l. In a combined wood sawing and splitting machine, a frame, a driven rotatably mounted saw positioned centrally of the frame and located towards one side thereof, a pair of pivotally mounted elevated opposed rocker beams located at opposite sides of the frame and extending lengthwise thereof, said beams having their rear ends overhanging the rear ends of the frame, a wood splitting axe secured to the rear end of each rocker beam, said axes being reciprocated in the vertical plane in the rocking of the beam, means for alternately reciprocating the forward ends of the beams to give a chopping and return stroke to each axe, chopping blocks located at the rear corners of the frame beneath the axes and a driven endless conveyor mounted within the frame and adapted to receive the wood blocks cut by the saw and deliver the same rearwardly to the chopping blocks.

2. In a wood sawing and splitting machine, a substantially rectangular frame having therear part thereof open, a rotatably mounted saw shaft carried by the frame and passing across the same, a wood cutting saw secured to the shaft and located at one side of the frame, a pair of opposed lengthwise extending elevated and pivotally mounted rocker beams carried by the sides of the frameand having their rear ends overhanging the rear part of the frame, chopping axes secured to the rear ends of the rocker beams, chopping blocks mounted on the frame beneath the axes, a forwardly positioned transversely extending driven crank shaft having the cranks thereof oppositely disposed, connecting rods connecting the cranks with the forward ends of the rocker beams and a driven endless conveyor mounted within the rear part of the frame and adapted to receive the blocks cut by the saw and deliver the same rearwardly to a location adjoining the cutting blocks.
