EDWIN S. PHILIPS, ()F KENNETT SQUARE, PENNSYLVANIA, ASSIGNOR TO THE AMERICAN ROAD MACHINE COMPANY, OF KENNETT SQUARE,

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed August 15, 1905. Serial No. 274,264.

To all whom it may concern:

Be it known that I, EDWIN S. PHILIPS, a citizen of the United States, residing at Kennett Square, county of Chester, and State of Pennsylvania, have invented a new and useful Improvement in Mounted Screen-Bins, of which the following is a full, clear, and exact description, reference being had to the ac companying drawings, which form a part of this specification.

My invention relates to portable or mounted screen-bins adapted for handling crushed stone.

Mounted screen-bins consist, essentially, of a frame mounted on axles, the bin proper, mounted on the frame, having pockets or compartments, a screen above the bin to receive the crushed stone, having sets of perforations of different sizes adapted to assort the stone and deliver the same into the several pockets, and chutes leading from the pockets to deliver the assorted stone from the pockets to wagons.

The object of the invention is to provide means to raise or lower the bin, and with it the screen, and at the same time raise or lower the screen. relatively to the bin, thereby enabling the center of gravity of the Wagon to be lowered when the'outfit is not in use and it is being transferred from place to place,while enabling the screen and bin to be placed in the most advantageous positions when in use.

Figure 1 is a side elevation of the machine with the bin-frame and screen-frame raised. Fig. 2 is an end elevation of same. Fig. 3 is a vertical section on the line 3 3 of Fig. 2, on an enlarged scale. Fig. 4 is a transverse sec tion, also enlarged, on the line 4 4 of Fig. 1. Fig. 5 is a similar section on the line 5 5 of Fig. 1. Fig. 6 is a detail side elevation of a modified way of securing the main operating-chain. Fig. 7is a front elevation of same. Fig. 8 is a perspective view showing another modified form of raising and lowering mechanism.

a a are the wheels on which the carryingframe is mounted. The carrying-frame consists of the side bars I), the uprights or posts 0, the cross-bars (Z, and the braces e, bolted to the lower cross-bars and the corner-posts.

Within the carrying-frame is the binframe, adapted to move up and down within the carrying frame in telescopic fashion. The bin-frame consists of a box the upright corner-posts g of which extend above the box.

Within the bin-frame is the screen-frame, which is adapted to move telescopically up and down Within the bin-frame.

The screen-frame is composed of the posts h, the side bars 6, and the cross-bars j. The rotary screen 76 is supported on the frame in the usual manner.

Extending lengthwise through the binframe and turning in bearings in the front and rear walls thereof is the shaft Z. The following mechanism, actuated and controlled by the shaft Z, is provided both at the front and rear: 777, is a hand wheel secured to shaft Z. n is a worm on shaft Z. 0 is a shaft running crosswise and turning in bearings on the bin-frame. p is a worm- Wheel fast on the shaft 0 and engaging the worm n. g g are sprocket-Wheels or pulleys on the shaft 0. About eachsprocket-wheel g extends a sprocket-chain 1", one end of which is attached to the upper cross-bar of the outside carrying-frame, while the other end is attached to the hooked end of a rod 8, secured to one of the posts of the screen frame. Turning in bearings in the upper projecting ends of the corner-posts of the binframe is a cross-shaft Z. a a are sheavepulleys on the shaft Z. About each pulley u extends a chain 1), one, end of which is attached to the upper cross-bar of the outside carrying-frame, While the other end is attached to one of the posts of the screenframe.

The apparatus is shown with the binframe and screen-frame raised to their extreme uplifted position, which is their normal position When in operation.

To drop the bin-frame and screen-frame, one or both of the hand-wheels m are turned, thereby, through the medium of the Worms n, worm-wheels p, and shafts 0, causing the sprocket-wheels g to climb down the sprocketchains 1", thus lowering the bin-frame. As the bin-frame moves down the pulleys u, beingsupported thereon, descend with the bin frame, and as the chains Q), Which pass over the pulleys a, are secured at one end to the carrying-frame and at the other end to the stant the distance between the points of attachment of the chains. The turning of the hand-wheel is continued until the bin-frame rests on the carrying-frame, at which time the screen-frame will rest on the floor of the bin-frame. All the working parts are thus brought to a low position, this lowering of the center of gravity rendering the bin very stable and enabling it to be readily hauled from place to place.

To elevate the bin-frame and screen-frame to their normal working positions, one or both of the hand-wheels m are turned, there i by through the medium of the worms n, worm-wheels p, and shafts 0 causing the sprocket-wheels g to climb up the sprocketchains 1, thus elevating the bin-frame. The pulleys a, being supported on the bin-frame, rise with the latter, and as the chains v,which pass over the pulleys u, are secured at one end to the carrying-frame and at the other end to the corner-posts of the screen-frame the pulleys u pull up the ends of the chains secured to the screen-frame, and thus elevate the screen-frame relatively to the bin-frame. At the same time the sections of the chains 1 between the pulleys g and rods 8 are lengthening, thus permitting the screen to rise, as described.

When the bin is raised for work, the weight of the bin and its contents is supported by means of cross-pieces w, resting on brackets m, secured to the posts of the carrying-frame, and the weight of the screen is supported by means of a pin or bolt 10, passed through the post of the bin and the post of the screenframe. The chain and raising mechanism are thereby relieved from strain when the bin and screen are in use.

y designates the usual legs or supports, hinged to the side bars of the carrying-frame. These legs are swung into position to take the weight of the load when the screen-bin is in operation. They are held in this position by hooked rods 2, pivoted to the side bars of the carrying-frame and engaging pins 7 on the supporting-legs. When the bin-frame and screen-frame are lowered preparatory to moving the bin on the road, the legs y are swung lnto an upright position above the side bars of the supporting-frame and are held in this position by the hooked rods 2.

The bin proper may be provided with any desired number of compartments, for each of which there is a discharge-opening, in front of which is a hinged discharge-chute 8, provided with raising and lowering tackle 9.

The partitions 11 in the bin should be hinged at 12, so that they can be folded down to permit the screen-frame to descend.

In the modifications shown in Figs. 6 and 7 the rods 8 are removed and drums or pulleys 2O substituted for the sprocket-wheels or pulleys g, each chain or cable r being coiled about its corresponding drum and secured.

thereto. To raise the bin-frame, the drums are turned bymeans of the hand-wheel and intermediate connections, so as to wind chains 1' about the drums. To lower the bin frame, the drums are turned so as to unwind the chains.

In the modification shown in Fig. 8 in place of the sprocket-wheels g, chains 1", rods 8, shafts t, pulleys u, and chains '0 the following construction is provided: Secured to eachcorner-post of the carrying-frame is a bracket 30, having a rack 31. Secured to the shaft 0 are pinions 32, engaging the racks 31 and a sprocket wheel 33. Turning in hearings in the upper projecting ends of the corner-posts of the bin-frame is a cross-shaft 36, on which are secured the sprocket-wheel 35 and the pinions 37. A sprocket-chain 34 passes around sprocket-

wheels

33 and 35. Secured to the corner-posts of the screenframe are the racks 38, engaging the pinions 37. To raise the bin frame and screenframes, the shafts 0 are turned by means of the hand-wheel and intermediate connections, so as to cause the pinions 32 to climb up the racks 31, thus elevating the bin-frame. At the same time the shafts 36 through the sprocket wheel and chain connections described are turned so as to cause the pinions 37 to climb down the racks 38, thereby elevating the screen-frame. A reverse rotation of the shafts causes the bin-frame and screenframe to descend, as Will be readily understood.
