MEASURING- AND CONVEYING DEVICE FOR CONCRETE AN D OTHER MATERIAL.

Specification of Letters Patent.

Application filed May 27, 1915. Serial No. 80,814.

To all whom it may concern:

Be it known that we, LUDWIG Enron and J osEPH EIRIGH, both citizens of the German Empire, and residents of Hardheim in the Grand Duch of Baden, Germany, with the ost-oliice a dress Walldiirnerstrasse 65-66,

ave invented new and useful Improvements in or Relating to Measuring and Conveying Devices for Concrete and other Material, of which the following is a specification.

In connection with endless conveyors it has already been proposed to construct the transverse walls of the individual sections or com artments in a movable manner or to make t e bottom parts thereof movable so thatat the delivery point the material may be completely removed from the individual.

sections and the conveyer may, if desired, be cleaned by means of a scraper or wiper. Ac cording to this invention a conveying device of the above kind is so arranged that it may simultaneously be employed to measure the material conveyed b it. To this end the ttom parts are made adjustable particu larly at the point at which the conve er passes through the feed receptacle so t at the transverse walls or bottom parts may at the delivery point be positioned higher or lower according to the uantity of material required to be conveyed uring one complete travel of the conveyer.

If desired, the device may also be so constructed that a reciprocating slide is used in the place of a conveyer band, whichslide guides for the move 'le transverse walls or is fitted with a number of compartments provided with bottom flaps, whichlatter are capable of being lowered to a determined adjustable depth for the purpose of receiving from the feed receptacle a determined quantity of material. The material thus received by the compartments is intermittently located in front of wipers arranged above the slide and then conveyed further.

Several such conveying bands may be arranged side by side or several feed receptacles may be located above each band.

Several constructional forms of a device according to this invention are illustrated by way of example in the accompanying drawings, in whic Figure lrepresents a lateral view of one form of the conveyer which is arranged on an appropriate carriage and may be tipped to any desired oblique position.

Fig. 2 is a longitudinal sectionof Fig. 1, an

Fig. 3 is a top plan view thereof;

Fig. 4 shows in partial section a second constructional form in which the conveyer band is composed of individual curved plates so as to enable the conveyer to form a pre cise cylindrical surface at the reversing points.

Figs. 5, 6 and 7 show diagrammatically various arrangements and positions of a conveyer arrangement.

Fig. 8 shows a conveyer arrangement for the simultaneous conveyance of stones, sand,

mortar and the like.

Fi 9 shows a constructional form in whic use is made in the place of movable transverse walls of movable bottom parts in the form of flaps of corresponding compartments, and

Fi .10 and 11 show a further constructiona form of a reciprocating slide in two different positions.

Referring first to Figs. 1 to 3, it will be seen that a frame 3 is pivoted at 2 on a carriage 1 and is provided with a driving shaft 4 carrying a pair of sprocket wheels 5 adapted to be driven by anylmown driving mec anism. The whole frame 3 may be tipped about the shaft 2 from the position shown in dotted lines lines or any other intermediate means of a hand wheel -6 which t rough the agency of a worm gear 7 operates a chain 9 secured at 8 to the framework. An endless band-like conveyer 11 is adapted to travel around the sprocket wheel 5 on the one hand and about a. curved guide 10 on the other.

osition by This conveyer consists of a number of individual sections hinged together by pins "'12. These sections or compartments are provided with lateral walls 13 carrying sectors 14 so shaped as to completely close the spaces or crevices produced between the lateral walls during the travel of the compartments over the air of the sprocket gears 5 and over the i e 10 and thereby to prevent material om dropping out or from tween the compartments.

The material is supplied from a hopper 15 traversed by the conveyer and the delivery takes place at 16 where a wiper or scraper 17 'is arranged for the purpose of cleaning the bottom parts and lateral walls of the conveyer in a continuous manner.

Patented June 4, 191s.

to that shown in full collecting be Arranged in the individual sections are slots through which the transverse walls 18 (see Fig. 2) are adapted to move. These transverse walls are secured to members 20 rotatable about pivots 19 and provided with rollers 21 adapted to travel along a guide 22 adjacent to the conveyor. This guide is so arranged as to be adjustable below the hop e1: 15 thereby enabling the transverse walfs 18 to project to a determined extent above the conveyer band and, therefore, to receive a determined quantity" of material from the supply hopper. ()n the remaining portion of the ascending band the guides are stationary and more closely arranged to the ban in order that the transverse walls may at these points still further projcct and that the material may be prevented from falling out.

For the descending portion of the band, that is to say. on its idle side. the guides are 50 arranged as to cause the transverse walls to be completely retracted and, eonsetmenl ly. to enable the wiper 17 to completely clean the band and the lateral walls.

The adjust able wrtion ol the guide 22 located below thehopper 15 is marked 23. It is provided at its lower end with an incline 24 which is movable in a block and on its upper end is provided with a rack 26 adapted to engage with a small toothed Wheel 27. At this point a block 26 is again arranged to form a bearing.

Mounted on the shaft of the toothed wheel 27 is a hand wheel 28 by means ot which the toothed wheel 27 may be rotated and thereby the rack 26 and the guide portion 23 adjusted at will. By this displacenn-nt duev to the oblique parts referred to, this liide portion will be set at a higher or lower fiavel as will be readily understood.

The incline 24 also serves to cause the individual rollers 21 to ride up the adjustable guide portion 23 from the lower guide portion 29 at the lower reversing point. For the curved guides 10 a sprocket wheel similar to sprocket. wheel 5 may be substituted.

In the constructional form shown in Fig. 4 the arrangement is similar except that the individual bottom parts 11 of the compartments are not straight but are curved in order to enable the conveyor at the reversing points where it travels over the sprocket gears or over th curved guides to assume a completely smooth cylindrical surface capableof being easily cleaned by a wiper.

5 shows diagrammatically the cone or constructed in a triangular form in r'l iich the individual sides of a triangle may be of any desired length and form any desired angle one with the other. Fig. 6 shows the conveyer band in horizontal and Fig. 7 in a vertical arrangement. Fig. 8 shows a portion of the conveyor band in vertical arrangement, the construction being s n-h as to enable the conveyer to carry slmultaneously, for instance, bricks I50 and sand or mortar 31.

According to Fig. U which shows a section of another n'ioditication, the bottom parts of the convcyer are adjustable instead of the transverse walls thereof. In. this case the individual sections of the conveyor are constructed in the form of flaps 31 rotutable about 32 and carrying rollers 33 running along an appropriate guide 34. 'lhe front walls 35 are permanently secured so that compartments 30 are produced into which the. material may drop from the hopper 15. The discharge of the compartments is eilcel'ed in this (use by the. guide 3-} being placed nearer theconvcyei' at the dclivery point whcrcbv the flaps 31 are caused to rolnle about their pivots and are thus llllHt'tl {lush with one another. as indicated in the lower part oi Fig. .l. so that at. these points the band again forms a continuous surface apable ol being readily wiped by a scraper. in the idle side of the convcvcr band the llaps are all raised until they enter lho hopper 15 as indicated at 37 where it will a lso be seen that the corresponding part 3S ol the guide for the rollers 33 is located at a higher level.

Instead of constructing the transverse walls in the form of ares they may be straight or they may consist of corrugated sheet metal or the like.

()ther means may, of course. be employed for adjust ing purposes in the place of guide rollers and corresponding guides of the kind described. For particular purposes the transverse walls may be in the form of individual in'ongs or rakes.

Now what. we claim and desire to secure by Letters Patent is the following:

1. In cijinveyers of the character described. a. continuous trough ctnllplbilltl segments. said segments being 'pivotally joined together, in combination with a plu ralily oi movable walls adapted to cooperate with said segments so as to constitute a pinl'ality of receptacles and adjusting means for the movable walls whereby the capacity of the receptacles may be varied.
