Application filed April 9,

To all whom it may concern:

Be it known that I, GEORGE A. HILLER, a citizen of the United States, residing at East Rochester, in the county ot'Monroe and State of New York have invented certain new and useful Improvements in Elevators, of which the following is a specification.

The object of this invention is to provide a new and improved form of movableelevating mechanism which. is especially adapted for use in the construction of concrete alls for dwelling houses, building foundations, retaining walls in tact for all concrete construction work in which the concrete must be poured from an elevation in order to secure proper distribution of the concrete in the forms with av minimum amount of labor.

Another object of this invention is to provide the elevating mechanism with means whereby not only the concrete can be han dled most efficiently, but also the sections of the forms into which the concrete is to be poured.

In the accompanying drawing:

Figure 1 is a front elevation of the elevating mechanism with the uprights partly broken away.

Figure 2 is a side elevation of the elevating mechanism with the uprights partly broken away.

Figure 3 is a detail sectional view of one of the guides for the elevating tipple, the section being taken on the line 3 3 of Figure 2. I

Figure 4 is a vertical sectional view of the upper end of the elevatingmechanism, the section being taken on the line 44P of Figure 1.

Tn the several figures of the drawing like reference numerals indicate like parts.

Concrete elevators are used to elevate the mixed concrete to a predetermined height alongside the form or mold of the structure to be filled therewith. This height must be greater than the height of the forms into which the concreteis to be poured, in order that. the chute for distributing the elevated 1921. Serial No. 460,011.

concrete can be held at an inclination suf-- ficient to allow the concrete to flow from the top of the elevator to the desired point in the mold by force of gravity. 1

The elevator forming the subject matter of my present invention is preferably built on a base made up ingthis instance of two pairs of cross beams 1, 1 and 2, 2; one pair being mounted on top of the other and at right angles thereto.. On the under side of. the beams 2. 2 are provided the bearings 4- in which the shafts-5 and 6 are mounted to rotate. The shafts in turn carry on theirouter endsthe wheels 7, 8, '9 and'll) which are adapted to support the base of the elevator, and also make it movable for the purpose of changing the location ofthe elevator.

Suitably fastened to each of the beams 1, 1 and facing each other are a pair of uprights 11 and 12. These uprightsare each formed by two angle irons and are riveted to the inner side, of each of the beams 1, 1. Each pair of angleironsis supportedby one otthe beams 1 and the members being properly spaced apart at suitable intervals by means of the spacing bars 13 on the outside of the angle irons and with the cross beams 14 and 15 at the top thereof. The crossbeams 14 and 15 in turn are spaced apart by a pair oi spacingmerobers 16 and 17, one at each end of the crossfbars 14. and 15. An open or rectangular frame is thus formed the top of the uprights 11 and 12 which holds these uprights properly spaced 2. art from one another, corresponding to the spacing cfthese same parts at the point where they are mounted to the cross bars 1 of the base. i I

Mounted to telescope in each oft-he pairs of uprights 11 and 19. is a second pair of uprights 18 and 19. Each of the members oi this second pair of uprights is preferably made up of an angle iron of somewhat smaller dimensions than the angle irons forming the first pair of uprights. A third pair of uprights 20 and 21 preferably similarly constructed may be mounted to telescope in the second pair of uprights. This third pair of uprights carries a. heachat the top of which the pulley 23 is mounted. I

The head may be made up of a pair of I beams 24 and 25, which in turn are mounted on top of the overhanging arms 26 and 27. The arms'28 and 27 are fastened to the outside of each of the uprights 20 and 21 respectively and the I beams 24 and 25 rest on top of them and span the distance between the uprights 20 and 21 at their upper extreme ends. Mounted between the beams 24 and 25 in suitable bearings supported thereon is the pulley 23 over which the hoisting cable 30 is adapted to travel.

One end of this hoisting cable is preferably permanently attached to the beams 24 and 25 and passes from this point down around the pulley 31, carried between the cross beams 32 and 83 of the tipple carrier or frame. From the pulley 31 the cable passes around the pulley 23, as above pointed o'ut, and thence over the pulley 85 and down on the outside of the uprights to a pulley 36 that is supported on brackets mounted near the base of the elevator. From there the cable ispassed over a horizontally pivoted pulley 87 to a winding or hoisting drum (not shown) by means of which the cable is pulled or released in order to raise or lower the tipple of the elevator. i

The frame or carrier that carries the ti pple comprises preferably the angle irons 38, 39, 4O and4l, forming guides which are adapted to slide on the outside of the uprights forming the guides therefor. At the top the angle irons are spaced apart in pairs by means of the angle irons 42 and 43, and similar angle irons are providedat the bottom to properly space the angle irons of the frame apart so as to make it slide on the inside between the pair of uprights previously described. The angle irons 38 to 41 inclusive are held against the inside of the uprights by means of the pair of cross beams V 32 and 33 which are attached to the spacing angles 42 and 43 at the top of the frame. A similarpair of angles is provided at the bottom of the frame to bind the spacing member of vthe frame together. Mounted 1 between the angles forming the spacing Ine'mbers at the lower end of the tipple frame is the rock shaft 46, on which the tipple 47 proper is supported. This tipple comprises the frame 48 which tapers toward the bot-. tom thereof and between which the concrete container 49 is carried. The concrete con- 7 tainer' is carried above the rock shaft 46in '41 forming part of the tipple carrier are mounted the dogs 50 and 51. These dogs are adapted'to engage withtheir front ends into suitable slots 52 and 53 in the top edge of the container 49. This engagement of the dogs with the container normally holds the container from tipping forwardly while the container is being filled and raised. When the tipple carrier is elevated by he hoisting mechanism in the manner above described the. dogs 50 and 51 are brought into contact with the cam bars 54 carried on the outside of the upper set of uprights. On the further movement the dogs are forced to ride up on the inside of the cam bars 54 and in so doing are forced to tilt into the dotted line position indicated in Figure 5. This in turn moves the forward end of the dogs out of engagement with the slots 52 and 53, which releases the tipple and allows it to tilt forward.

At the point where the tipple is tilted in this manner the tipple has just passed the hopper 55, carriedon the upper set of uprights, The forward end of the tipple then rests on the inner edge of the hopper while the tipple carrier is stillufurther elevated until the container has reached the position shown in Figure 4 in which it is almost perpendicular to the upright of the elevator. The contents of the container begin to slide into the hopper as soon as the tipple tilts and makes contact with the hopper 55, but the tipple is not emptied until it has been elevated into the position" shown in Figure 4.

The bottom of the tipple is carried above the pivot around whichit rocks. This makes the tipple top heavy so that as soon as the tipple is released by the dogs the tipple begins to tilt. The shallow curved bottom of the container is provided so that the concrete contained therein will easily slide out therefrom and empty into the hopper 55. The curvature of the bottom is made in such a way so that the container has a continuous bottom without sharp bends and curvatures therein and this insure-s a quick release of the concrete contained therein. 7

Mounted at the top of the last pair of uprig and supported by the beams and 25 is a boom 56. This boom is supported at its. outer end by the triangular frame work on the bottom of which is carried the hopper 55. The triangular frame in turn is supported by the arms 26 and 27 at the top and the braces 57 near the bottom thereof. Both the arms 26 and 2? and the braces 57 project out from the uppermost pair of uprights. with which they form a unit.

On the outer end of the boom 56 is mounted a pair of tackles 58 and 58%.. One of these tackles is used for the purpose of hoisting and placing the discharge end. of the distributing trough 59. to which it is fastened with. the one end thereof. The other of the tackles. is used for the purpose of hoisting and handling the sections of the forms of themould into which the concrete is to be poured. The receiving end of the distributing trough is anchored to the hopper by means of the chain 55 which is 4 of each of the uprights When the bolts are suspended from the cross bar 55 of the triangular frame. This chain holds the end of the chute against the exit of the hopper, and the engagement of the trough with the hopper permits the trough to bewrung sideways at any horizontal angle in front of the elevating mechanism, and the tackle is adapted to hold the trough at the desired vertical angle or place it on the form by which in turn it is supported.

The elevation to which the concrete is raised for the purpose of distributing the concrete and filling the mold therewith is governed by the position of the uppermost pair of uprights. These uprights carry the hopper 55, boom 56 and thetilting mechanism which automatically releases the tipple so that it dumps its contents into the hopper.

The upper uprights 20 and 21, as well as the intermediate uprights 18 and 19, telescope in the first and second pair of uprights respectively, as heretofore pointed out. This makes it possible to raisethe second pair of uprights with relation to the first pair of up- I rights, and the third pair of uprights with relation to the first and second pair of up rights. To do this a winch 60 is mounted on the braces that support the first pair of uprights. This Winch is operated by the crank 61 and rotates the drums 62 and 63. The

cables 64 and 65, of each of which one end is more particularly with reference toelevators fastened to its corresponding drum, are passed over the pulleys 66 and 67 at each side of the top of the first pair of uprights, which guide the cable down between. the first pair of uprights. A hook 68 is fastened to the end of each of the cables 64 and 65. These hooks are adapted to engage the under side of suitable connecting links 69 which bridge each. pair of uprights near the bottom thereof.

A connecting link 69 is provided for each pair of angle bars of the second and third pair of uprights and when it is desired to ele-v vate the second pair of uprights the hooks 68 are hooked under the connecting link of this pair of uprights. On the operation of the winch 60 the cables 64 and are wound up on the drums 62 and 63 respectively and inso doing pull the hooks on the ends of the cable up between the first pair of uprights. The pair of uprights to which the hooks are attached are thus raised and the upper portion thereof moves out between the preceding set of uprights. After the desired elevation has been reached suitable bolts are passed through the holes 71 provided in the sides passed through the holes 71 in the first pair of uprights into the holes 71 in the second pair of uprights, with which they register, the second pair of uprightsis heldin the elevation to which it has been raised by the Winch on the first pairof uprights. -In the the outer sides of the upright, thus, in effect,

providing a channel between the flanges in which another upright may operate and may be housed, as will be seen by referring more particularly to Fig. 3; The frame or carrier on which the container is mounted operates between two of the uprights and has at opposite sides a pair of angle irons, the members of each of these pairs having'each a flange in a planewith the flangeon the other member, and a flange parallel with the flange on the other. member, the parallel flange forming a channel between them in which is received one of theuprights. The opposite ends of each of these angle irons are split and deflected away from these uprights. This arrangement, as a whole, permits 'thecarrier to move from one upright to another While being held to its guiding upright.
