of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to chutes for delivering wet concrete from the upper floor of a high building in course of construction to the various lower floors, but it may be used for other material and in other locations where suit-able; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a side view of the chute arranged in a building. Fig. 2 is a side view of the lower end portion of the chute, drawn to a larger scale. Fig. 3 is a rear view of the two delivery pipes. Fig. 4 is a section through the lower part of the chute showing the adjustable retardingplate. Fig. 5 is a detail plan view of the bottom plate of the intermediate deliverybranch. Fig. 6 is a plan view of an alternative arrangement of dischargedoor. Figs. 7 and 8 are a section and an end View showing another discharge-door.
A is a portion of a high building in course of construction, and B are the various floors. The frame-work ofthe building is erected first, and a concrete mixing-machine of any approved construction is installed in the up per part of the building and is provided with a suitable motor for driving it. The cement, sand, cinders, or other material of which the concrete is formed, is elevated to the concrete mixer, and the concrete ismixed at the top of the building, and is delivered when ready for use through a chute C to the various lower floors for use in complet-' ing the building. The concrete-mixer remains in one location until the whole building is completed, and a great saving of time and labor is found to occur by handling the concrete in this way.
The delivery chute O is tubular and is formed of jointed sections of any approved length so that the chute can be lengthened or shortened at will by varying the number of sections used. Each pipe section has a collar 0 riveted around its top edge and having a flaring mouth into which the lower end of the pipe section next above it is slipped, so that the ends of the pipe sections abut against each other. The delivery chute has a suitable receiving hopper at its top for receiving the wet mixed concrete from the concrete-mixer.
The chute C is supported at the various floors by means of collars D which are clamped to it by suitable bolts, which pass through projecting flanges D on the collars, and which rest on short beams (Z arranged under the said flanges and crosswise of the joist beams of the floors, each floor being provided with a suitable opening Z) to admit the delivery-chute. v
The bot-tom section of the delivery-chute is provided with an inclined delivery-pipe E, and this pipe E has a suitable dischargedoor F which controls the discharge of the concrete. The pipe E has a retarding-plate G secured inside it and provided with a slidable plate or portion 9. The plates G and g are arranged diagonally of the pipe E, and their object is to sustain the major portion of the weight of the concrete in the delivery-chute and leave an aperture of desirable size for the concrete to pass out of when the discharge-door F is opened. The position of the slidable plate g is varied to suit the nature and condition of the concrete being used, and the'two plates are secured together by bolts g when the slidable plate has been suitably adjusted. One ofthe said plates is provided with a slot to permit the slidable plate to be slid soas to vary the width of the discharge opening between it and the lower side of thepipe E.
The discharge-door F is pivoted by a pin 7 to a frame H which is secured to the lower section of the discharge-chute, and a handle I is provided for opening the door, the open position of the door being indicated by the dot-ted lines. The door is held in any desired position by means of a pin 2' which is inserted through holes in a quadrant-plate J, and which engages with the handle. Any other approved form of discharge-doo r'may be used in carrying out this invention. In Fig. 6, the discharge-door F is pivoted to the delivery-pipe E by a pin f so that it slides crosswise of the mouth of the pipe like a cheese-cutter, theopen position of the door being indicated by the dotted lines. This door F is provided with an operatin handle I, and it can be opened to any desired extent.
In order to deliver concrete occasionally at any desired floor, without shortening the delivery-chute, certain of the pipe sections of the delivery-chute are provided with lateral openings K which are normally closed by cover-plates 7c. WVhen one of these cover-plates is removed a bottom plate L is inserted through the opening and is secured in an inclined position, and diagonally of the chute, with its lower end portion projecting through the opening.
M is a branch delivery-pipe provided with a curved plate at which is secured over the opening K, and the pipe M is also secured to flanges 70 on the plate L. The pipe M is inclined to correspond with the plate L, and it is provided with a dischargedoor F and retarding plates G 9 similar to the same parts hereinbefore described. The plate L is not secured direct to the main pipe C, but is retained therein by being secured to the pipe M by bolts m which engage with the flanges 7c.
The weight of the delivery-chute is preferably distributed over the various floors, and the weight of the delivery-pipe E and its connections is supported by the floor next above them. N are suspension-rods provided with turnbuckles 90.. These rods are provided with clamps or clips p at their upper ends which engage with the lower flanges of rolled beams d, but any other supporting devices may be provided.
The lower ends of the rods N are secured to a collar D which is clamped on the discharge-pipe. The turn-buckles are used to hold the suspended pipe sections in close engagement with each other, and also to support the weight of the concrete in them.
Only a few floors are shown in the drawings, but the delivery-chute is intended for use chiefly in tall buildings which have many floors. The delivery-chute also forms a storage-chamber for the concrete, so that the concrete-mixer can be worked continuously, and even when the discharge of concrete from the discharge-pipe is very intermittent. The concrete from the dischargepipe is usually taken away in wheel-barrows. WVhen all the concrete required on one floor has been supplied, the deliverychute is shortened by removing sutficient of the pipe sections, and the concrete is then delivered on the floor next above, and so on, until all the floors have been supplied.
The delivery-chute has been shown in a vertical position in the drawings, but it may be arranged in an inclined position, if desired, and it may be used for any material and in any location to which it is applicable. The deliverychute has been described as used for wet concrete, but it may also be used to deliver the mixed dry materials to the different floors, and the water may be added to the dry materials at the places they are finally delivered.
In the alternative arrangement of the discharge-door shown in Figs. 7 and 8, the discharge-door F slides crosswise of the pipe E between guides s and 25, so that the dedelivery of concrete can be regulated, and the door is provided with a handle I for operating it. The guide 8 on the upper side of the door is preferably a flat plate secured crosswise of the pipe leaving an opening at its lower part; and the guides t are preferably brackets secured inside the pipe and overlapping the side edges of the door.
What I claim is:
l. The combination, with a building provided with a series of floors having openings in them, of a temporary chute for building material formed of a series of similar tubular sections and having a straight and unobstructed passage, said chute being arranged loosely in the said openings and provided-with a discharge door, removable collars provided with projecting flanges which are clamped on certain of the chute sections and beams arranged in pairs at the sides of the chute between the said flanges and the floors and supporting the chute.
2. The combination, with a floor provided with an opening, of a delivery-chute for concrete arranged loosely in the said opening, said chute being formed of tubular sections and provided with a discharge-door for retaining the concrete in it, a collar secured to the lower part of the chute, a collar secured to the upper part of the chute above the floor, a pair of beams arranged between the floor and the upper collar so that the weight of the chute and its contents is distributed, and suspension rods secured to the said beams and passing through the said opening and having their lower ends connected to the lower collar.
In testimony whereof I have afiixed my signature in the presence of two witnesses.
HOWARD S. GARDNER.
