LUMBER=PILER.

SPECIFICATION forming part of Letters Patent No. 363,287, dated May 17, 1887.

Application filed November 19, 1886. Serial No. 219,415. (No model.)

To all whom it may concern/.- I

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 being had to the accompanying drawings.

My invention is an improvement on the device shown and described in Letters Patent No. 321,348, granted to me June 30, 1885; and the object thereof is to provide a device which, while acting upon and embodying the essential principle of said former invention, may be easily transported from place to place, shall occupy comparatively little space when not in use. and which, notwithstanding these and other advantages, shall be less expensive than the former patented device.

To this end it consists in the construction and combination of parts, hereinafter fully described and claimed, and illustrated in the drawings, wherein- Figure 1 is a perspective View of my improved device with the upper parts of some of the upright posts broken off. Fig. 2 is an end view of the fixed end of the device. Fig. 3 is a view of one of the tracks or rails, show ing the hinge-joint between the two parts thereof. Fig. 4 is a view of the movable end of one of the rails, showing its hinge-connection with its supporting-bracket. Fig. 5 is a view of the end of one of the pivoted end bars, B. Fig. 6 is a view of the meeting ends of shafts E E, showing their connection by beveled gears.

As illustrated in the drawings, A A A represent upright posts or supports, of which the four posts, A A A A, are stationary, and are preferably secured in any appropriate manner to the'platform U, which is mounted on any suitable running-gear, as the wheels at. The inner faces of the supports A A, 8tc., are preferably provided with vertical grooves, as shownin the said former patent. These grooves serve as guides for the vertically-adjustable brackets G G C, to which the rails D D are secured. These brackets may be independent of each other, as shown in the drawings; or they may be united in pairs by transverse cross-bars, as shown in said former patent.

At or near the tops of the supports or posts A A A are fixed the pulleys G G G, of which the pulley at G is provided with two sheaves. Near the bottoms of the posts A A. the transverse shaft E is mounted in suitable bearings, said shaft being provided with the drums e 6, located, as shown, near said posts. Near the bottoms of the supports A Aa like shaft, E, is similarly mounted. These two shafts are connected by beveled gears 0 e*", as shown in Fig. 6, or otherwise, with the longitudinal shaft F, mounted in bearings on the posts A A on one side of the device, so that the revolution of said shaft F produces a simultaneous revolution of the shafts E and E.

and then over one of the sheaves at G on each 7 central post. Gables or ropes g are secured to the brackets O and pass up and over the other sheaves at G. Thetwo cables on each side of the device are then preferably secured together by splicing or otherwise to form one cable, which passes down, and is secured to the drum 6 on each side. Cables 9' are secured to the brackets C, and pass over the sheaves G and down to the drums e e, to which they are secured. The revolution of the shaft F causes, through the instru mentalities above described, all of the brackets G 0'0 to be raised or lowered at the same time and at the same speed. I have thus secured vertically-adj ustable tracks of the same length, and which serve the same purpose as those described in said former patent, by the use of one less transverse shaft E, and by the use of a longitudinal shaft only one-half as long as that shown in said patent.

In order that the device shall occupy as little space, when not in use, as possible, and at the same time be always ready for use, I have 5 The power to revolve the shaft F may be ap-v conceived the plan of folding one part of the device against the other. I prefer to accomplish this result in the following manner, to Wit:

The bars or braces 13 B, which extend be tween the posts A A on each side, are pivotally connected with each of said posts. The

IOC

end bars or braces, 'B 'B which extend between the two end posts, A" A, are pivoted to one of said posts and also to the vertical bar B. Upon the post A, to which the bars B 5 B are not fastened, I secure at proper intervals the brackets 11 b, 850., upon which the free ends of the bars 13 rest. These brackets are preferably of metal, and consist of a horizontal part, upon which the bars B rest, and a :0 vertical part, which is .adapted to hold said bars 13 against the post A. The ends of the bars'B" are preferably provided with a plate, 1), (shown in Fig. 5,) having two vertical ribs, 1) b*, which are adapted to lie, when in the posesnav the ends of thetracks D, the said tracks swing upon their pivots d and hinge c, and the connection of the tracks with their supportingbrackets is sustained at all times.

A car which forms no part of the present invention, but which is fully described in my former patent, rides upon the tracks D D, and is operated in substantially the manner described in said patent. In order to facilitate the loading of said car, I provide two or more horses, T T, which rest upon the platform U. The tops of these horses are provided with a series of rollers, t. The lumber to be piled or stacked is preferably introduced from the '15 sition shown in Fig. 1, on each side of the ver--.side of the device, and the ends of each piece tical part of the bracket 12, thus holding thebars B in the desired position and bracing this. end of the device.

A rope or cable, V, is secured to one of the braces, B or B (preferably the latter.) The H rope is passed around pulleys or through the eyes 12 'v 1), which are provided with. a smooth; bushing, in the posts A AA. Uponthe other side of the device the rope V is secured to the 2 5 post A and passed through theeyes o '0 in the postsA A. The rope Vis made longer than the rope V by the distance between the eye 0; and the point where the rope V is attached to the bar B After-passing through the eyeso o, &c.,,the two ropes V and V are spliced or otherwise joined together to form the rope V, as shownin Fig. 2. This rope passes down. and is secured to the drum 8 on the shaft S, whichismounted in bearings on the postsA This shaft is revolved by a crank, S, or otherwise, and is held at any desired point by; the ratchet and pawl 8*. As this shaft is re-- volved, and the rope V thereby wound upon the drum 8, it draws first upon the ropeV (it,

beingv the longer) and swings the bars B up-.

ward upon their pivots, as shown in dotted lines, until said bars lie close to the post A. As the rope V is still farther wound upon the drum 3, the strain is applied. equally to the.

ropes V and V thereby causing the bars, B"

on each side of the device to swingsignultane ously on the pivots which connect themwith the posts A A until the bars B and posts, A lie close to the posts A. ,The device now oc- 5o cupies about one-half the ground roomv it did before it was folded, and can readily be transported from place to place in this condition, yetit is ready for almost instant use. When; the. rope V is allowed to unwind, theweight of the parts causes them to assume the position.

swing upward with said" brackets.

6 5 joint, 0, as shown in Fig. 4. When the brackets 0 move upward with they posts A and carry rest upon the horses T .T. As anew piece of lumber is laid upon the. horses, the lumber already laid may be readily pushed across on the rollers it, until the entire course is laid, :with few steps and comparatively little labor ou the part of the workmen. The: course of lumber is raised and deposited. on thegrowing pile in the manner described inmy former patent.

Having thus described my invention,--what 'Iclaimas new, and desire to secure by. Letters Patent, -is- 1.v In a lu-mber-pil-er, the. combination-of-stationary track-supporting posts with. the movable track-supporting posts. and pivoted intermediate: connections, and means for oscillating said connecting, parts upon the pivots which connect them with; the stationary posts, substantiallyas and for the purposespecified.

,2. In a lumber-piler containing a. stationary and a movable part, the combi'nation,with said two parts, of means for folding said movable part against said stationary part, substantially as and for the purpose specified.

3. In a lumber-piler, the combination of a frame or platform mounted on suitable runhing-gear, and four posts rigidly secured to said platform, with two movable posts and longitudinalbraces pivoted to the'movablev posts and to two of the stationary posts, and means for oscillating said braces about the pivots in the stationary posts, substantially as andv for the purposespecified.

4.. Ina lumber-piler, the combination of stationary posts and two movable posts with longitudinal braces pivotally connected with the movable posts and with two of said stationary posts, and transverse braces pivoted to one of said movable posts and adapted at their free ends to engage with the other movablesupport, and means for causing said pivoted braces to oscillate. on their pivots, substantially as and drum 8, the whole being combined substantially as and for the purpose specified.

6. In a lumber-piler, the combination of the stationary posts A A, the movable posts A the braces B, pivotally connected with one movable and one stationary post, with the ropes V V V and shaft S and drum 8, substantially as and for the purpose specified.

7. .In a lumber-piler, the combination of the movable posts A A with the brackets b, secured to one of said posts, and the braces B, pivoted to the other post, and the plates 1), secured to the free end of said braces and adapted to engage with said brackets, substantially as and for the purpose specified.

8. In a lumber-piler, the combination of the vertically-adjustable brackets O G O with the tracks D D, supported on said brackets,
