LUMBER-PILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,868, dated November 3, 1896.

' Application filed September 10, 1895. Serial No. 562,066. (No model.)

To all whom it may concern:

Be it known that I, HOWARD DANIELS, of Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Improvement in Lumber-Filing Machines, of which the following is aV specification.

My invention is an improved lumber-piling machine, and relates particularly to that class of such machines wherein the lumber is piled on edge, and the present invention is an improvement upon the machine covered in my former patent, No. 500,86l,dated July 4, 1893; and the invention consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective View of my improved machine. Fig. 2 is a side view thereof. Fig. 3 is a detail view illustrating the devices for binding the load. Fig. et is a detail View of the mechanism for holding the stakes up to the load. Fig. 5 is a detail view of one of the hooked stake-rings. Fig. 6 is cross-sectional View of the machine. Fig. 7 is a detail view thereof. Figs. S and 9 are'detail views of the stake-feeder. Fig. lO is a detail view of the cam, and Fig. ll is a partial vertical cross-section of the apparatus.

The framing may be similar to that employed in my said former patent. The swinging conveyer-frame A is hinged at a, and is arranged to lower to position to receive the lumber from the chute AB and to lift the courses of such lumber successively to position upon the truck O, which truck may in general respects be similar to that employed in my said former patent.

The connection between the swinging frame and its operating gearing is joined to said frame at a point above the pivot-point of such frame, because it affords a stiff and effective arrangement of the parts.

In operating the said frame I connect it by pitmen A' with cranks A2 on a shaft A0. This shaft, as shown most clearly in Fig. ll, supports the notched or cam pulley F and has a gear-wheel A4 on a drive-shaft A0, such shaft having a clutch-section A7, by which the pinion A5 may be keyed to the shaft or freed at will. This clutch is operated by a swingi'ng arm A8, connected by a link A0 with a swinging arm A10,Which is pressed against the cam F and into the notches f thereof by a spring A11.

In operation, the shaft A0 turning continuously, the arm A10 when in the position shown in Fig. ll will, by parts A8 and A0, hold the clutch A7 in engagement with the pinion A5, and the shaft A3 will be caused to turn so long as the arm A10 remains in the position shown in Fig. ll,which will be until one of the notches f comes in line with the arm A10, when the latter will be drawn by the spring A11 into the notch and the shaft A3 will cease revolving until the arm A10 is again adj usted to set the clutch A7 into engagement with the pinion. This may be `effected by the pull-cord A12, which may extend within convenient reach 0f the operator, so that when the shaft A3 and the swinging frame A are at rest with the frame A in either its upper or lower position the operator may set the shaft A3 in motion by drawing upon the cord A12.

The parts A8, A0, and A10 and the cord A12 may be similar to corresponding parts in my former patent, but in the present case I make the cam with two notches, so the frame A can be stopped in both positions.

The retarding-timbers D operate similarly to the corresponding parts of my former patent, but differ therefrom in form, being tapered or sloped at d above the chute to form a flaring inlet for the boards sliding down onto the conveyer-frame.

In the use of my patented machine it has been found that the separating-stakes are not always sufficient to hold the courses up in Vertical position while the conveyer-frame is returning to receive another course.

To properly support the courses, I provide the pile-retaining bar E, which is movable into and out of position in rear of the lumber pile as the successive layers are applied, and 1 to afford time for the movement of the bar E into operative position I provide the cam F IOO point where .it is down in line with the chute. This holds the course of lumber in the vertical position until the traveling bar can be run up to hold the course while the next course is being collected. This bar It moves longitudinally in a vertical direction, being held at its lower end in suitable guides E', while its upper end moves through a guide-opening E2 in the framing, such opening E2 being elongated to permit alimited back-and-forth play, the upper end of the bar E resting back of a stop E3 when such bar is in its extreme uppermost position.

The bar E drops by gravity, and to properly set its upper end when lowered so it will on its next upward movement adjust properly alongside the last-applied course o f the pile I provide a yielding presser G, which is arranged adjaeent to the path of the bar and operates to deflect the same when moved downward from alongside one course to position to move alongside the next course when the latter has been applied. In the construetion shown this presser G is preferably a lcver pivoted at g between its ends, having a roller g at one end to bear against the bar E and having a weight g2 at its other end operating to set the .roller against the bar E in such manner as to set the said bar in position to rise alongside the last-applied course.

To lift the bai-EI provide in connection with the drive-shaft II, from which the whole machine derives its motion, a paper frictionpulley lI, below which is an iron friction-pulley I on a shaft I2, which shaft carries a spool I3, from which a chain or other connection Il extends up over a sheave I5 and thence connects with the bar E near the lower end of the latter. NVhen the shaft I2 is turned by the bearing of its friction-pulley I against the pulley II, the bar E will be raised, and when such pulleys II' I are out of contact the bar will fall by gravity. To this end the shaft I is supported at its end adjacent to the pulley I in a sliding box fi, so the pulley Il can be set into or out of contact with pulley II, the movements of the shaft being effected by means of the lever J, connected With the operator-s rod J.

To hold the bar in elevated position until it is desired to lower it, a concave brake K, lined with leather or the like, is arranged beneath the pulley I, so that when released from bearing against pulley II such pulley I will drop into the brake and prevent the spool from unwinding and holds the bar E at any height desired. To let the bar drop, the pulley I is raised out of the brake, but not enough to bring it into contact with the friction-pulley ll. In operation the barE is left up with its top behind the stop E3 until a new course of lumber is brought up by the frame A. This pushes the truck ahead and the swinging frame stops. The bar E, being now between two courses, is dropped by the operator, `is pressed by the yielding presser G back so it will pass up back of the last course until its topl sets back of the stop E3, as before, when the frame A can be lowered for another course. In this operation as each layer of boards is moved, upward by the eonveyerframe the latter also moves up with it the stakes which separate such layer from the following one, and these stakes are held in place by the strain of the boards on the truck acting against the latch overhead and the rock-shaft on which the conveyer-frame is hung below. As the conveyer-frame rises to a perpendicular position the stakes carried up thereby work downward, so that their lower ends rest on the top of the truck which holds the load of lumber, and in reaching such position theA lower ends of the stakes come in behind the said rock-shaft and their ripperA ends are caught by the latches. Then the strain of the boards holds them in place until the next course comes up. This strain is occasioned by the weight mechanism that tends to pull against the load at bottom and top.

The parts E* serve as stops for engagement by the plate E5, secured to the bottom of the bar E to limit the upward movement of the said bar.

The stake-feeders L L are arranged one at each side of the swinging frame A, and comprise side beams L', which incline upward to the level of said frame A when the latter is in lowered position. These beams L have mortises Z to receive the sprocket-wheels l\I and grooves Z" to receive the chains Im running on said wheels. The chains m are carriers having lugs m every second link. The wheels M are on shaft M', and on the lower end of the upper shaft N is iiX'ed a ratchetwheel N. A pawl-earrier O turns on this shaft and has a pawl O' engaging the wheel N, a portion O2 to engage a stop on the feederframe, and a point or portion O3 for engagement by the conveyer-frame, the latter preferably having a lug O4 to engage the portion O3, as shown. The spacing-strips being placed on the lugs of the chains,the movement of the frame A imparts a step-by-step motion to thc said chains through the mechanism described, and the stakes are fed oneat a time up to the tops of the feeders, where they pass through notches p into the rest-plates I), which latter may be similar to corresponding parts in my former patent and need not be described in detail. By this construction of feeder the stakes are fed positively to the swinging conveyer-frame.

In practice it has been found that the stanchions shrink more or less in going through the kiln, which gives them a little play and tends to allow the top of the pile to open in the process of loading and let boards get into the spaces so formed. To avoid this, I provide the tension devices consisting of the shafts Q and Q, having sprocket-chains, bearingstops Q2 to receive the ends of the truck-stanchions, and to the shaft Q is fixed a spool,

from which a cord q, having a weight q', is disposed over suitable guide-pulleys, so the stress of such weight will operate against the tops of the stanchions, keeping the load snug and tight all the time. l

To bind the pile when loaded, I provide malleable-iron rings R, adapted to fit the rounded ends of the stanchions and have projecting hook-like lugs R.

Levers S are pivoted at S on the overhead timbers directly over the truck and have connected chains S2, provided with hooks S3 to grasp the stanchions. By this lever mechanism the stanchions may be drawn tightly together and secured by trace or other chains put across the top and linked to the hooks R of the rings R. Y To quickly run the load out of the machine, I provide in practice a shaft T, having a pulley T', which can be set into contact with the pulley II', and a spool T2, from which a line can be run over suitable guides and connected with the truck.

I do not desire to limit myself to the exact framing shown, as different locations may render changes necessary, and this applies to the location and connection of the workmans levers.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
