To all wk m it may concern:

Be' it known that I, 'WILLIAM LARSON, a citizen of the United States, residing at Bonner, in the. county of Missoula and State have invented a new and useful Lumber-Piling Machine, of which the following is a specification.

he invention relates to improvements in lumber piling machines.

The object of the present invention is'to improve the construction of lumber piling machines, and to provide a simple and comparatively inexpensive portable machine, designed for handling both lumber and other heavy material, such as logs, rails, timbers and the like, and capable of enabling, the same to be readily transferred from a wagon to a stack and vice versa', and adapted to be for loading and unloading cars, boats and various other vehicles.

A further object of the invention is to provide an extensible lumber piling machine of this character, adapted to be varied in length to arrange it for handling different kinds or lengths of material.

With these and other objects in view, the the construction and parts hereinafter fully described, illustrated in the accompanying drawings, and ointed out in the claims hereto appended it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Fi ure 1 is a side elevation of a lumber pi ing machine, constructed in accordance with this invention. Fig. 2 is a transverse sectional view onjthe sectional view on the line 33 of Fig. 1. Fig. 4 is a detail sectional view, illustrating the manner of slidably mounting the rear adjustable upright frame onthe wheeled supporting frame. Fig. 5 is a detail view, illustrating the manner of mounting the central topshaft.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which able material and 2-2 of Fig. 1. Fig. 3 is a horizontal verse bar 21 and having is illustrated the preferred embodiment of the invention, l--designates a supporting frame equipped with front 2 and 3 mounted on front and rear axles 4 and 5. The front and rear axles are connected with front and rear bolsters 6 and 7, secured to one side of the horizontal supporting frame, ning gear may be employed, and the machine is equipped with a pole ortongue 8 to enable draftanimals to be attached to it for hauling it from one point or place to another.

The supporting frame, which is horizontal, is composed of spaced side sills 9 and transverse connectin bars or beams, and it has mounted on it ront and rear upright frames, which taper upwardlyf The front upright frame, which is fixed to the supand rear wheels but any other suitable runporting frame, is composed of oppositely I inclined guiding standards 10 and 11, constructed of channeledmetal, or other suitrigidly secured at their lower ends to the side sills and connected at their upper ends by a top cross piece 12.

\ The oppositely inclined standards 10 and 11, which are also connected at their lower portions by a lower transverse bar 13, are provided at their outer faces with longitudinal grooves or channels, located between the side flanges of the standards and receiving the outer flights or stretches of oppositely inclined endless conveyer chains M and 15, arranged onupper and lower polygonal chain or sprocket wheelslfi and 17'.

The channeled standards andythe endless conveyer chains are arranged in different transverse planes, as clearly illustrated in Figs. 1 and3 of the accompanying drawings,

and the upper and lower transverse connect ing bars or pieces 12 and 13 are located between the transverse planes of the standards and the conveyer chains and are secured to the adjacent faces ofthe standards, the latter being located at opposite sides of the transverse connecting bars or pieces.

The rear upright frame, which is adjustable along the horizontal supporting frame, is composed of oppositely inclined guiding standards 18 and 19, connected by a top."

transverse bar or piece 20 and a lower trans their lower ends fitted against the outer faces of the side sills 9 of the wheeled frame and providedv with approximately hook-shaped lugs or flanges 22, projecting inwardly and downwardly from the rear faces of the standards 18 and 19 and extending into and en-.

gaging longitudinal guide grooves 23 in the upper faces of the side sills 9. By this con structionthe rear upright frame is slidably' The loweruends of the standards 18 and' 19 are equipped with downwardly and inwardly extending bearing arms 28, arranged inpairs and secured to the side faces I of the standards 18 and 19 at points below the sills 9-and consisting of inwardly extending horizontal portions and depending inclined portions. extending downwardly and inwardly'from the horizontal portions. The horizontal portions of the bearing arms 28 extend to points beneath the sills 9 in slightly spaced relation with the same but in close proximity thereto to prevent the hookshaped lugs or flanges 22 from being accidentallyllifted out of engagement with the longitudinal grooves I The bearing arms 28 are also located at opposite sides of the lower sprocket wheels 27, and they are adapted to slide the latter along a pair of lower longitudinal shafts 29, provided with longitudinal grooves 30, which are engaged by keys 31 of the lower polygonal chain or sprocket wheels 27. The shafts 29,which 3 ,are located below the side. sills of th'e'sup porting frame, are journaled in front and rear bearings 32 and 33, depending from opposite sides of the frame at the front and back thereof, as clearlyshowir in Fig. 1 of the drawing". The lower front endless chain or sprocket wheels 17 are keyed or otherwise suitably fixed to the front "portions of the lower shafts 29, and the upper polygonal chain or mounted on an upperi centrally arranged shaft 34, journaledin suitable bearings 35 and 36 of the top connecting 'bars of the" front and rearv upright frames. The front.

upper chain or sprocket wheels are keyed" or otherwise fixed to the front portion of the upper shaft 34, which is provided with a longitudinal groove 37 to receive keys 38 of the upper rear chain or sprocket wheels. whereby the latter. are slidably interlocked with and are adapted to move longitudiat one side of the machine sprocket wheels are nally of the upper shaft 34 when the rear upright frame is adjusted backwardly or forwardly. The rear upright frame is equipped at the top with arms 39, which, as clearly illustrated in Fig. 1 of the drawings, are spaced apart to receive the upper ,rear chain or sprocket Wheels between them, and they cause the same to slide on the shaft 37 when the rear upright frame is adjusted to arrange the front and rear endless conveyer chains the proper distance apart tosuit the lumber or other material operated on.

The polygonal chain or sprocket wheels are grooved to receive the links of the chains, which are arranged between the peripheral side flanges or. walls of the grooves,

and the said wheels have straight polygonal faces 40 at the bottoms of the grooves corresponding with the length of the links of the conveyer chains. which form a carrier or conveyer, are'pro The conveyer chains,

vided at intervals with angularly disposed projections or arms 41 inclined upwardly and outwardly while traveling at theouter flights of the endless conveyer chains, and adapted to support pieces 42 similar material to convey the same upward and downwardly at the opposite side for loading and unload ing material either to convey the same from cars, boats, etc, to wagons or for transferring the material from wagonsto a lumber pile or stack. The outer flights of the conveyer chains at one side of the machine travel upwardly while the outer flights of the eonvever chains at the other side of the machine travel downwardly and the arms are at a position so that'whcn the arms at one side of the machine carry the'material over the top, the arms of the cha-ins.atthe opposite side of the machine will be in positiori 'to receive the material. -'l?he ,ch ains- If Qof'the drawings and the lumber carrying arms or, progections downwardly -and outwardly are =inc'lined while traveling are oppositely inclined, as clearly shown-in along'the inner flights of' the conveyerf ch a ins.

Thea-earn iri ht frame of the machine is adjusted by means'of-a pair of' l'ongitudi nal screws a3, located at opposite'sides of the machlne and ]-ournaled at their'front portions in bearing openings 44'of the lower transverse connectmg bar 13 of the front upr ght frame and engaging threaded open' andare adapted to receive a crank handle or other suitable meansforhrotating' them to" slide tliewrear upright iframe along' the The adjusting ings 4.5 the .lower transverse connecting bar 21 th-e rear uprightfname. -The front ends 1-Giofthe adjustingscrcws are-squared when rotated to slide the rear upright frame backwardly or forwardly according to their direction of rotation. v, i

The rear upright frame is braced and secured in its adjustment by oppositely inclined braces 47, composed of overlapped sections pivoted at their outer ends 48 to the upright frames and having inner overlapped portions provided with longitudinal slots 49 for the reception of bolts 50, or

. other suitable fastening devices for securing the overlapped sections in their adjustment. The upper portions of the upright frames are also connected by a horizontal brace 51,

composed of overlapped sections connected attheir outer ends to the upright frames and havinginner overlapped portions provided with longitudinal slots 52 and secured in their adjustment by a bolt 53, arranged in the said slots 52. The inclined braces are located at opposite sides of the machine, and

the horizontal brace connects the frames at the side of the machine at which is arranged the inner flights of the outer endless conveyer chains. By this arrangement the upper horizontal brace is placed clear of the conveyer chains. Any other preferred arrangement of braces may, of course, be employed. The endless conveyer chains may be operated by a motor 54 of any preferred type, or. any other suitable means. The motor shaft- The upright frames are equipped at the outer sides-of their standards with loops 58, arranged at different elevations and adapted to receive the hooked terminals 59 of skid bars 60 and 61. The skid bars 60, which are adapted to extend downwardly at an inclination from the lower portions of the upright frames, are preferably supported at their outer ends by legs 62, piv-,

oted at their, upper terminals to the outer portions of the skid bars 60 by bolts 63, or other suitable fastening means, which will permit the legs and the skid bars 60 to be folded when not in use. The skid bars 61,

--which are arranged at an inclination, are

adapted to extend downwardly and outwardly from the loops at the lumber pile, as clearly illustrated in Fig. 2 of the drawings. loops permit an adjustment of the skid bars to enable them to rest properly on the lum- The-hook-shaped terminals and theber pile as the latter increases in height. The arrangement of the skid bars in Fig. 2 of the drawings permits lumber to be taken from a lumber wagon 64 and transferred to a lumber pile 65. The lumber from the wagon is placed on the skid bars 60 in the path of the inclined carrying arms of the conveyer chains, and is carried upwardly at one side of the machine to the top thereof by one set of conveyer chains and is then carried downwardly at the opposite side of the machine by the other set of conveyer chains, which deposit the lumber autoinatically on the inclined skid bars il. The material is then placed on' the lumber pile.

The machine is adapted for handling lumber and various other material, such as.

heavy timbers, rails and logs, and it in M constructed of any size and strength'i-te adapt it to the character of the materialito 3 be handled.
