This invention relates generally to elevators, and particularly to an elevator for concrete.
The main object of'this invention is to construct a simple and efficient form of elevator by means of which concrete may be raised to a desired elevation with a minimum amount of effort and with the maximum smoothness of operation.
The second object is to construct an elevator of the class described which will be easily transportable, set up and taken down and which will adapt itself to varying conditions of the ground upon which it is used.
The third object is to so construct the elevator that the unloading point can be changed with very little effort.
I accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawings, in which:
Fig. 1 is a side elevation of the device showing the elevator tower lowered in full lines and raised in dotted lines.
Fig. 2 is a vertical section taken along the line 2--2 in Fig. 1.
Fig. 3 is a horizontal section taken along the line 3-3 in Fig. 1.
Fig. 4 is a fragmentary section taken along the line 44 in Fig. 1.
Fig. 5 is a shortened section taken along the line 55 in Fig. 1.
Fig. 6 is a perspective view of one of the tracks showing the closing gate in position.
Fig. 7 is a section taken along the line l-l in Fig. 5.
Similar numerals refer to throughout the several views.
Referring in detail to the drawings, there is shown a truck I upon whose rear end is mounted a standard II and on whose forward end is mounted the upright tower support I2. A winch I3 is mounted on the frame of the truck I0 and carries the hoist operating line I4 which is also used to raise and lower the tower I'which is hingedly attached to the standard II on the pins IS. The tower I5 consists of four upright members I! and I8 and the intermediate tracks I9.
On the tracks I9 are mounted the slotted runners 20, the upper ends of which are joined by the arch 2I and the clevis 22 to the line I4. The lower end of each runner is joined by a pin 23 to the lower end of the bucket 24 to one side of its center line nearer the members I'l than to the members I8. The straps 25 are secured to similar parts the bucket 24 for the purpose of reinforcing the pins 23. The bucket 24 has secured on the sides thereof the angular stops 26 which can engage the sides of the runners 20 although normally they are not in contact therewith.
The bucket 24 is provided with a pair of wheels 21 which ride against the faces 28 of the upright members I8. Since the bucket 24 is slightly out of balance, it follows that the wheels 21 bear against the faces 28 at all times until they reach 10 the openings 29 which are formed in the members I8 permitting the bucket 24 to assume the position shown in dotted lines in Fig. 5.
Attached to the outside of the uprights I8 is a discharge spout 30 at whose upper end are 15 mounted the rollers 3I upon which the side 32 of the bucket 24 rests when in a discharging position. The spout 30 may be connected to any desired chute or may discharge directly into a conveyor or conveyance as desired.
It will be noted that the uprights I8 are provided with a number of openings 29 those of which are not in use are closed by the gates 33 which are held in place by means of the bolts 34. The uprights I8 are provided with slotted brack- 25 ets 35 which receive the heads 36 of the discharge spout 30 whose outer ends 31 are supported by the rods 38.
At the lower end of the tower I5 is mounted a crank shaft 39 whose arms 40 support the lower 30 end of a bucket filling chute 4| whose upper end 42 is supported by a brace rod 43 whose lower end 44 is slotted to permit it to receive the pin 45 which is fastened to the uprights I1. The upper end of each rod 43 is attached to the chute 4| by 5 means of the pins 46 to which are also secured the perforated braces 41 which are secured to the uprights IT by means of the bolts 48. A hand lever 43 is secured to crank shaft 39. The purpose of this mechanism is to enable the operator 4a to move the chute 4I away from the path of the bucket 24.
There is provided an anchor 50 on the lower end of the tower I5 to which the line I4 can be attached for raising and lowering the tower I5. 45 A second anchor 5| is attached to the tower I5 and it has attached thereto a perforated tie rod 52 which passes through a perforated bracket 53 on the frame of the truck Ill. The purpose of the tie rod 52 is to hold the tower I5 in a desired 60 upright position with relation to the body of the truck I0. A pin 53--A holds the rod 52 in a desired position.
The operation of the device is as follows:
When it is desired to elevate a quantity of con- 55 crete, it is first necessary to move the bucket 24 to a lowermost position as shown in Fig. and then by operating the lever 49 to move the chute 4| to the position shown therein, that is, with the discharge lip of the chute 4| within the boundaries of the bucket 24. Concrete is then discharged from a truck or mixer into the chute 4| from whence it passes into the bucket 24. When the bucket 24 is sufliciently loaded, the lever 49 is operated and the chute 4| is withdrawn to the position shown in dotted lines in Fig. 5. The winch I3 is then operated and the bucket 24 is raised to a point where the wheels 21 pass through the openings 29 and since the bucket 24 is no longer supported laterally, it will turn on its shaft pins 23 and discharge its contents through the discharge spout into whatever receptacle is provided.
When it is desired to move the apparatus, it is only necessary to attach the line l4 to the anchor 50 and release the guy 54 and the tower l5 may be lowered at a desired speed until it rests upon the support l2.
It will be noted that the line I4 passes around the sheaves 55 at the upper end of the tower IS.
The precise details of this construction are immaterial and may be varied considerably without departing from the spirit of this invention.
It is desirable to construct the tower I! of sections so that it may be lengthened or shortened as required for a particular set up.
When hoisting concrete, the line l4 passes around the sheaves B8 and II, but when raising or lowering the tower I, it passes around the sheaves 56 and II.
I claim:
A tower i'or elevating concrete having in combination a pair of upright tracks and a pair of guide rails parallel to said tracks and spaced therefrom, said guide rails having a plurality of openings formed therein, removable closures for said openings, a pair of runners slidably mounted on said tracks having means for operating same in unison, an unbalanced bucket having its lower end hinged to said runners in a manner to cause the upper end of said bucket to be urged toward said guide rails, wheels attached to said bucket near the upper end of its heavier side, adapted to ride against said guide rails and to pass through those openings from which the closure is removed, in a manner that said bucket may tip to a discharging position, a discharge spout supported by said guide rails under the end of said bucket when in a tilted position, together with a pair of stops secured to opposite sides of said bucket near its upper end adapted to engage said runners when said bucket is in an upright position.
