LUMBER-PILER.

'PT-CIICATEON forming part of Letters Patent No. 321,348, dated June 30, 1885.

Application filed February 2, 1885. (No model.)

T all whom it 71mg/ concern: l

Be it known that I, CARLOS E. DUNSHEE, of the city of Chicago, in the county of Cook and ,State of Illinois, have invented certain new and useful Improvements in Lumber- Pilers, of which the following is a description, reference beinghad to the accompanying drawings, in which- Figurel is a side elevation of my improved lumber-piler. Fig. 2 is an end View of the same. Fig. 3 is a top view of one of the cylinders,hcreinaftcr described, which are mounted upon the car. Fig. et is a crosssection of one of the upright posts, and Fig. 5 is a detailed view of the operating devices attached to the central upright.

The piling of lumber, especially in lumberyards where, because of lack of ground, the piles must be made very high, is a difficult and expensive operation,and adds very materially to the cost of the lumber.

The object of my invention is to provide a novel combination of mechanism whereby lumber may be rapidly and regularly piled and to any reasonable height.

To this end it consists in the construction and combination of parts hereinafter described, and definitely pointed out in the claims.

In the drawings, A A' A2 A3, Snc., represent upright supports or posts. These uprights I prefer to make in parts or sections of about ten feet in length. The uprights A A', 85e., are six in number, three in front and three behind. The transverse distance between the posts I prefer to make about Atwelve feet and the longitudinal distance about sixteen feet; but these distances are not material, and depend upon the size of the lumber it is desired to handle. The sections c a are joined together by means of the metal caps c a,which are bolted securely to the ends of said sections, as shown. When the posts are placed in position,they are secured by the braces B B',&c., bolted or otherwise fastened thereto.

The inner face of each of the posts A A', d'0., is provided with a T -shaped groove, c2, extending from top to bottom. Nithin these grooves play the ends of the cross-beams C C C, the center beam being necessarily bent, as shown in Fig. 2, which beams extend transversely across from one upright to the other.

I) D represent rails or traelrs,wl1ieh are secured to said cross-beams C at appropriate distances from the uprights A A', 85e.

Fixed to each ofthe uprights A A', fue., near the foot thereof, are bearings in which the transverse shafts E revolve.

Mounted upon each of the shafts E,near the inner faces of each of the uprights A A', die., are the two drums c', as shown in Fig. 2, and upon one of the outer ends of said shaft E are mounted the beveled gear-Wheels c. The shaft F is mounted at right angles to the shaft Ein bearingsf, attached to each of the three front posts, as shown in Fig. I,Which shaft F bears the beveled gear-wheels f' f f', which mesh each with one of the gears c upon the shafts E, so that a revolution of one shaft causes a like revolution of all.

At the top of each upright A A', Src., are fixed the sheave pulleys G G' Gi, 81e., as shown. A wire rope or cable. g, is secured to each end of each of the cross-beams C, passes up over the sheave G, and then down, and is fastened to the drum e'.

The means for revoivingv the shafts E are preferably secured to the middle upright A, and consist in the following to Wit: 'Vithin bearings h 71.', attached to said upright A, is mounted the shaft H. This shaft H has mounted upon it the ratchet -whecl h2, the sprocketwheel h3, and the crank or driving wheel hi. Upon the shaft li, mounted upon said upright A, is a sprocket-wheel, ci, which is connected with the sprockebwheel h3 by the drive-chain J. It is evident, therefore, that a revolution of the shaft H, Whether imparted by hand or in Whatever manner imparted, causes, through the instrumentality of the sprocket-wheels 72?' and el and drivechain J, a revolution of the transverse shaft E,to which said sprocket-Wheel e'l is attached, and this, as before explained, revolves the two other transverse shafts E. By thcsemeans the drums e' Wind up the ropes g, and thus raise the cross-beams C and tracks D to any desired height, and the ratchet Il. holds the same in that position.

Upon the tracks D D a car, K, is run,ashere inafter described. This car K consists of a light frame mounted upon trucks, asshown.

The Vcylinders M M are mounted in bearings upon the frame of the car at each end thereof.

IOO

These cylinders M M are mortised, as shown in Fig. 3, and through these mortises the bent bars or hooks m pass and are sustained by the bolt-heads m at their upper ends. Attached rigidly to the upper sides of the cylinders M M are the arms m2 and m3, respectively.

At or near the center of the car atransverse shaft is mounted in bearings Z, which shaft has fixed rigidly at or near its center the arm L,

extending on both sides of said shaft. The arm Z is also fixed to said shaft near the end thereof, as shown. The arms m2 m3 are connected with the opposite ends of the arm L in such a manner, as shown, that when the shaft to which the arm L is attached is revolved the two cylinders M M are each revolved in the opposite direction.

Attached to the side of the frame of the car K is the bent arm 7c, which supports a swiveled pulley, 7c".

Bolted to the rail D upon its under sideand inclining away from the rail, so as not to interfere with the movement ofthe car K, isa bent arm, N, also bearing a swivel-pulley n.

A cord, a', is fastened to the arm Z and passes over the pulleys k and n and down within reach of the operator, whostands by the central upright A.

The arms P P/ are bolted to the under side of the rail D,and bear the sheaVe-pulleys p p', respectively. The ropes p2 and p3 are attached to opposite ends of the car K, as shown, and pass over the pulleysp and p' down within reach of the operator.

The depending arms R are fastened to the cross-beam r of the car K, slightly upon a slant to the perpendicular, and shape the end of the pile of lumber.

The operation of the device is as follows: The lumber which it is desired shall be piled is laid on horses, one course or more at atime, between the posts A and A. rl`he cross bars C C C are now allowed to descend, carrying with them the tracks D D and car K. As the car is thus descending the cord n is pulled upon, thereby turning the cylinders M M. This turns back the hooks m, so they will clear the ends of the boards. When below the level of the boards the cord is released and the hooks m are perlnitted to resume their normal position, as shown in Fig. l, below the boards, which they will do by reason of their own weight. The power is now applied to the crank or driving-wheel, and, as before eX- plained, the drums c wind the ropes g about thelnselves, thereby elevating the cross-beams C, tracks D, and car K, carrying the course of boards. Vhen they are at the properheight, so that the boards are above the level of the pile of lumber, the cord p is pulled upon, which pulls the car over the lumber-pile until the arms R strike against the face of the pile. Then the operator pulls upon the cord n', which, as before described, turns up the hooks m and dropsV the boards upon the pile. The cordp2 is pulled upon by the operator, which drives the car back to the position as shown in Fig. l, when the operation just described may be repeated until the pile has reached the desired. height. Y Y

The bearings in which the roller Mis mounted may be moved along the frame of the car as desired, and bolted at any point so as to take in any length of lumber.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent7 is- 1. In alumber-piler, thecombination of upright supports, sheaves mounted thereon at or near their tops, transverse shafts mounted thereon near their feet, drums mountedupon said transverse shafts, and alongitudinal shaft mounted in bearings attached to said upright supports and geared to said transverse shafts, with transverse cross-beams, tracks mounted upon said cross-beams, cables attached to said cross-beams, passing over said sheaves, and attached to said drums, and means for rotating said shafts, substantially as and for the purpose set forth.

l2. In alumber-piler,the combination of vertically-adjustable tracks and a car adapted to run on said tracks, and mechanism whereby the car is moved along said tracks, with depending hooks mounted upon said car and means for swinging said hooks in contrary directions, substantially asand for the purpose set forth.

3. In a lumber-piler, the combination, substantially as set forth, of vertically-adjustable rco tracks, a car adapted to run upon said tracks,

two mortised cylinders mounted in bearings upon said car, hooks which operate in said mortises, the arms M2 M3, attached to said cylinders, a transverse shaft mounted near the middle of said car,the arms L Z, attached thereto, rods connecting the arms M2 M3 and arm L, the arm k, and swivel-pulley 7d, with the arm attached to the track, the swivel-pulley n, and cord n', for the purpose specified.

4. In alumber-piler,the combination of vertically-adjustable tracks and a car adapted to run on said tracks with the pulleys p p', fastened to the under side of said tracks, and the cords 292113, attached to said car and passing over said pulleys, substantially as described, and for the purpose set forth.

5. In a car adapted to run on vertically-adjustable tracks, theY combination of two mortised cylinders mounted upon said carl and hooks operating in said mortises, and means for producing-a.v partial revolution of said cylinders in opposite directions, with depending arms attached to one end of said car, substantially as and for the purpose set forth.
