United States Patent CEMENT DISPENSING DEVICE David Joseph, 203 Governor St., Paterson, NJ.

Filed May 29, 1956, Ser. No. 587,980 Y 4 Claims. (Cl. 72-128) This invention relates to improvements in devices for laying building members such as blocks, bricks, slabs, and the like, and more particularly relates to devices for dispensing cement for placement between adjacent building members.

It is an object of the present invention to disclose devices which will facilitate the construction of walls with building members such as blocks or the like.

A further object of the invention is to provide devices for the more perfect construction of walls with building blocks, bricks and slabs than heretofore possible.

. Yet another object of the invention is to provide improved devices for the dispensing. of cement for placement between adjacent building members.

Other objects of the present invention will be more apparent in the course of the following description of a preferred embodiment thereof.

This invention is an improvement upon that portion of applicants copending application Ser. No. 387,579, filed October 22, 1953, now Patent No. 2,818,725, which relatesto the dispensing of cement into the hollows in the laid-up building members and between adjacent ones of such members. The device of the invention is characterized by the greater ease of its manipulation, the positiveness of feeding of cement to the desired locations, and the completeness with which the hollows and joints in the laid-up structure may be filled with cement.

Briefly, the device of the invention in its preferred embodiment and when used with a laid-up structure of hollow blocks comprises at least two cement dispensing devices of different character, one of which extends generally longitudinally of the laid-up structure and dispenses cement on the top thereof at the location of the edges of the blocks. The other dispensing device extends generally transversely of the laid-up structure, and dispenses cement on top of the structure at the location of the forward and rear corners of a vertical joint be- A clamp extending between two blocks may be used to facilitate the operation.

The dispensing devices are mounted on a common supporting framework disposed beside the structure. The devices may be easily and quickly disposed over successive zones of the structure as it is progressively laid.

The invention will appear more clearly from the following detailed description when taken in conjunction with the accompanying drawing showing by way of example a preferred embodiment of the inventive concept.

Figure 9 is a side view, partly in section, of a portion of the dispenser shown in Figures 2 and 3.

The cement dispensing device of the invention is used to apply cement upon a portion of a wall, generally designated 10, made up of hollow building blocks 11 (Fig. 7). Such blocks have outer edges 12 which are provided with cement dispensed by mechanism generally designated 14 in Figs. 1, 4 and 5. Adjacent blocks 11, which are' preferably laid up by apparatus such as that shown in application Ser. No. 387,579, when laid are spaced at short distance to form narrow crevices 15. Cement to fill crevices 15, thus to provide joints between the confronting vertical surfaces of adjacent blocks 11, is dispensed by mechanism generally designated 16.

Dispensing mechanisms

14 and 16 are carried by a laterally extending plate or framework 17 so as to lie in alignment above the top course of wall 10. Framework 17 may be mounted on a support 19, indicated diagrammatically in Figure 1, which may travel longitudinally of the wall, while the framework 17 may travel vertically with respect thereto, to allow the cement dispensing device to be positioned at the desired location above the top course of blocks. Support 19, the specific details of which do not form parts of the present invention, may be, for example, similar to that shown in Figure 11 of application Ser. No. 387,579 for supporting cement receptacle of the prior application.

In the construction shown in Figure 1, the support 17 carries four dispensers 14 extending in pairs parallel to the direction of the blocks 11, and two dispensers 16 extending transversely thereto. Obviously, this arrangement may be varied, if desired.

Proceeding now to a description of

cement dispensing mechanisms

14 and 16, each of the dispensers 14 comprises a container of symmetrical, trough-shape, having downwardly converging side walls 20 and spaced vertical end walls 21. Each dispenser 14 in the embodiment shown is of a length slightly less than the length of a block 11, and in operative position lies above an edge 12 of the block 11 as shown in Figure 1. The lower ends of sidewalls 20, which are spaced a distance at least generally equal to the width of hollows in blocks 11, are provided with oppositely laterally directed flanges 22.

The upper ends of the

walls

20 and 21 have flanges 22a which are attached to the plate 17 and by means of which the dispensers 14 are suspended from the plate 17. To aid in the distribution of the cement each dispenser 14 is provided with a horizontal, longitudinally extending agitator means 24 positioned centrally of the mechanism 14 adjacent its mouth at the lower end thereof. Means 24 comprises a rod 25 journalled in opposite end walls 21, and turned manually by a crank 26 on one end thereof. A U-shaped stirring member 27 having serrated longitudinal edges is secured to rod 25 so that the rod lies within the bight thereof.

Dispensers 16 lie transverse to dispensers 14, and are spaced from the latter a distance such that while dispensers 14 are being used to apply cement to the edges 12fdf'a bloek11,'dispensers16 are in posit-ion to dispense cement for filling crevices 15. Y 1

Each dispenser 16 comprises an upwardly open container of symmetrical trough-like shape. Such container has downwar'dly converging side wall 29, the lowera ejnds 'of which converge still more steeply at 30. The bottorn 31"ofi'the container, inwardly from each nozzle device?? 7 to 'be described-at the front and rear of the containing-is in the form of aninverted broad V, so as'to lead the cement contents of the container downwardly'to both I nozzles 32. As shown, thefcon'tainer of mechanism 16 is disposed-with itslo-ngitudinal axis above the space between blocks 11, and the container is of such'length that the end-walls 34 thereof lie generally in alignment-with the vertical front and rear walls, respectively, of thread j'acent blocks 11 forming the crevices-15 being treated.

V The dispensers 16 are suspended-from the plate 17'by their upper flanges 29a, r V V -Each nozzle 32 is formed between its'respectiv'e end wall 34 and the confronting outer edge of bottom 31 of the container, such outer edges each being flanged to provide-a vertical passage 35 between it and the end walL, '"Such passage may be of any desired horizontal section,

that shown being round. 7 p "Each nozzle' is provided with a disc-like elosui'e'member 36 pivoted to the respectiveend wall 34 by ahorizontal p'iv'ot -pin. j' Each closure member 36 is normally held 7 inhorizontali nozzle cl'o'sing, position by a'coil spring137 of such strength that it sustains'the pressure-of a fullrload 'of cem'ent in eontainerilti; Closure-member 36 may be 7 pened when-desired-by swinging-in'the appropriate di-- rection a handle 39'connec tedthereto; t

' To insure delivery of cement to nozzles 32, an agitator nieans '40 ismounted above each nozzle. Such agitator '7 V t mp isesa verticalrod 41 rotatably mounted intopand bottom angle brackets 42 'and 44, aflixed to end wall 34. a

' Atgthe .lower e'nd'of rod 41, immediately above closure 7 disc-36, there is afliXed-a U-shaped stirring member- 45 7 having serrated free edges, as shown. Rods 41 may be continuously-rotated, when the device 16 is in use, by an f 1 m gmas zone transversely of the wall where it is required toifill thecrevicesw Theuplacing of nozzles .32 overthe corners of the crevice insures full penetration by the cement into the crevices at such locations:

A clamp 50 shown in Figure 6 is used to hold together two blocks 11 during the work; The clamp 50 includes a threaded shaft 51 which carries two clamping members 52 and 53 provided with projecting

plates

54 and 55, respectively. One end of the shaft 51 carries a handle 56. The plates 54"and--'55* fit-into inner openings-9 provided in the :blocks '11. :-It is; apparent that when the handle 56 is rotated, themembers 52 and 53 will move either toward each' other -or =away:ifromL-each other to. increase or T diminish their gripsupon the blocksll. 7

Figure 8 shows a stopper or flow-controlling device 60 which may be used, if desired, in conjunction with a dispenser 16. The device 60 includes two

outer bars

61 and 62 and two spaced inner bars 63 and 64 which are held together by transverse bars '65 (and 66. Theiinher bars '63 and 64 have inclined surfaces 67 and, respec; tively,-' so that cement is guided into channels .69 andflfi formed between the outerrandinner bars. Inoperation the stopper 60 is placed over the crevices IS betWeen two a 2 adjacent blocks, so that the lower ends 71 and 72 ,ofithe channels 69-and :70 are located directly above thefcrevices 15. The dispenser 16 is then moved into a position; in

"which its dispensingopenings areilocated .direc'tlyabove the upper" ends 73 and "74 ofthechannels 69fa'ndi70:

' Then the flow of cement may be eifectively guided bythe channels. 7

While tliere' are above; disclosed but- 1a limited miniber ofembodiments of the structure of thepreserit invention,

a it is possible to produce-otherembodiments-withoutjdealdesired'amount of cement, when closure discs 36 are be thus successively moved in either direction, that is,

eitherztofthe right'orleft. t

After mechanisms 14 and 16thave thus performed their functions and have been 'moved to a new wall section, an operatortrowelsLthe cement dispensed 'by both the mechanisms. t

iPreferablYsthetrowel work is done when the dispensingdevicerhas gonethrough'several cycles, thereby leaving anappreciable' length of wall section with'dispensed cement thereinlan'd thereon, ready for finishing'by-the mason. t

I 'have found that the dispensing device of the inven- 7,

tion is of particular advantag'e in that it provides two parting from the inventiye concept herein disclosed and 'it is desired, therefore, thatjtmly suchijlimitations be i nposed onthe appended claims as are statedthereim 1; A dispenser for simultaneously depositing cement uponythe longitudinal edges of buildingblocksand into the crevices between successiveibuilding blocks-which are in spacedulongitudinal arrangement in thetop course .21 structure, the dispenser comprising at least one elongated dispensing mechanismadapted tto bexlocated above a longitudinal-edge of a building block for depositing cement-thereon, at least one second elongated dispensing mechanism'disposed at right angles to thefirst mechanism adjacent oneend thereof )fOl' depositingccment into said crevice, a single frame connecting and supporting such mechanisms, the length of the first'dispensingmechanism being equal to :that of a block, whereby when the first dispensing mechaniSm ;is located..over a building block, the second dispensing mechanism will ,be ,locatedover the crevice adjacent said building bloek the-second mechanism having two spaced vertical dispensing nozzles-a driven agitator ,above each nozzle, and: powervmeans'. connected with vsaid ;frame;, to drive both agitators, each of said agitators comprisingia vertical'shaft locatedv within and above the nozzle, and a stirring-member on theshaft adjacent the nozzle.
