y To all whom it may concern.'

Be it known that I, ALEXANDER J. INNns, a citizen of the United States, residing at Sutherland, in the county of OBrien and State of Iowa, have invented a neuv and uscful Machine for Making Concrete lJValls, of which the following is a specification.

The invention relates to improvements in machines for making concrete walls.

The object of the present invention is to improve the construction of machines for ma ing concrete Walls, and to provide a siniple and comparatively inexpensive molding machine of this character, adapted to enable a hollow concrete wall to be easily, rapidly and economically erected.

A further object of the invention. is to provide an automatic machine of this character, adapted to receive concrete or other plastic material from an elevator, and capable of carrying the material to and distributing' it along a wall under construction, and simultaneously leveling, packing' and smoothing the material, whereby the wall is automatically built up by the machine.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying' drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, Within the scope of the claims, may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Lilie numerals of reference designate corresponding parts in all the ligures of the drawmgs.

ln the embodiment ef the invention illustrated in Figs. 1 to 6 inclusive, the mold or n'iolding frame includes spaced sides 1, designed to be constructed of ordinary lumber, when the vertical faces of the Wall are to be smooth, but it will be readily apparent that the sides of the molding frame may be provided with any desired design for decorative purposes. The molding frame in the present form of invention is 'fixed or stationary, being' built up as the wall increases in height, and the said frame is designed to be removed from the concrete Wall after the material has set and hardened, like the melding frames or sections of a concrete wall molded in the ordinary manner. The machine is provided at the end of the molding frame with vertical guides or Ways 2 and 3, preferably formed by spaced timbers arranged in pairs at opposite sides of the molding frame and adapted to guide horizontal end shafts 4 and 5, provided at their ends with slides G, arranged in the said vertical ways. r1`he slides 6, which consist of rectangular blocks, have bearing openings and are provided at their outer ends with proj ectinghorizontal l lan ges 7, extending in opposite directions and -fitting against the outer faces of the vertical bars or timbers, which form the sides of the guides or ways 2 and. 3. The horizontal shafts 11 and 5 carry sprocket wheels S and 9, preferably arranged in pairs and receiving endless sprocket chains 10, but one or more endless belts or bands of any preferred form may be employed to adapt the machine to the width of the wall or other analogous structure to be erected. The endless sprocket chains, which are arranged horizentally, consist of upper' and lower nights, and are equipped with cars or Y ranged at an angle to each other and extending upward from the ends of the bottom sections of the car or carrier, and connected at their upper terminals to the transverse rod 12. The bars or members 14 and 15 form approximately triangular sides and may be constructed of any suitable material, either Wood or metal. rllhe bottom sections may, as illustrated in the accompanying draWings, be constructed of Wood and have their loWer faces covered With sheets 16 of steel, or other suitable material to enable them to Withstand the Wear incident to the friction produced by the grout. The sections of the bottom, Which are spaced apart to travel at opposite sides of a vertically disposed core 17 operate to level, pack and smooth the cement by traveling over the same at the upper face of the Wall, the necessary pressure being applied through the cars or carriers by the means hereinafter described. The dividing of the car into spaced opposite side portions forms practically tWo cars, and any number of separate series or sets of cars may be employed to mold a Wall or structure of the desired thickness, and a plurality of cores arranged in parallelism may be utilized for forming the necessary holloW spaces at the desired points. The bottom sections carry the concrete or other plastic material, and the cars or carriers distribute the material along the Wall and smooth and tamp the said material. rinhe 'flat loWer faces of the sections of the bottom of the car are particularly eflective and operate With a troWeling action in smoothing the cement.

The top of the molding frame is open, and the ends are closed at the upper portion of the Wall by means of vertically movable or adjustable end members 18 and 19, arranged vertically betWeen the sides of the molding frame and ec uipped With outwardly extending horizontill platforms 2O and 21. The end members 18 and 19 and their platforms are preferably constructed of Wood, but they may be made of any desired material, and the outer portions or platforms are supported by inclined braces 22 and 23. The end members and their platforms are raised automatically by the means, hereinafter described, as the Wall is constructed, and they are connected With and suspended from the transverse shafts 8 and 9 by vertical side bars 24 and 25, secured at their loWer ends to the platforms at the side edges thereof and provided at their upper ends With bearing openings for the said shafts 8 and 9. The end members are also connected With the vertically movable or adjustable core 17, Which is provided at the bottom With terminal projections 26, arranged horizontally and extending through slots 27 of the end members 18 and 19. By this construction the core and the end members are connected and are mutually supporting. The core also operates to space the end members and prevents undue pressure at the ends of the Wall.

T he core 17 Which is arranged in a vertical plane, extends longitudinally of the Wall, and is composed of separate detachable sections, connected by a horizontal top member 28 and spaced apart at their adjacent edges to provide slots 29. The cement is laid and molded at opposite sides of the core 17, Which forms dead air spaces, and the slots 29 permit the cement to floW through the core 17 so that the opposite portions of the Wall Will be united at intervals by transverse vertical Webs 30, Which divide the dead air space into separate cells or passages. The stability of the core may be increased by blocks or pieces 81, arranged in the slots 29 between the upper portions of the sections of the core, and the latter are adapted to be detached to permit the core to clear a framed portion or space, Where it is desired to provide a WindoW, door or the like. Also by this means arches or other openings may be formed in a Wall, or other concrete structure, and the slots or openings 29 Will admit of the arrangement of the rods or other means for reinforcing the cement.

The horizontal top member 28, Which extends laterally from opposite sides of the core, is supported and raised by the cars or carriers, Which are equipped at opposite sides With inWardly extending anti-friction rollers or Wheels 82, mounted on pivots or spindles, Which are carried by the inclined side bars 15 of the cars or carriers. The loWer flights or stretches of the endless sprocket chains are located directly above the horizontal top member of the core, and the sides of the cars or carriers extend slightly above the top member, the antifriction devices 32 being located intermediate of the ends of the said side bars 15 and arranged to pass beneath the top member 28. The front edge 33 of the top member 28 is beveled at its loWer face to provide an incline to enable the anti-friction devices to pass readily beneath the said top member 28, Whereby the latter is lifted and carried upward by the cars or carriers 11. The cars or carriers by engaging and supporting the top member of the core are subjected to the Weight of the said core, the end members and the gearing for operating the cars or carriers. The loWer face of the horizontal top member 28 is provided With a covering 34 0i sheet steel, or other material to prevent it from being worn by the rollers or wheels ol' the cars or carriers.

The material is delivered to the machine by means of an inclined elevator 35 of any preferred construction, having a discharge spout 36 at the top, located above a hopper 37. The hopper 37 is provided with a bottom 38, hinged at its inner edge 3Q and detachably held in its closed position by a catch 40, mounted on the body of the hopper and engaging the free outer edge of the bottom, as clearly illustrated in Fig. 4 of the drawings. The cars or carriers are moved from the front end of the machine to the rear end thereof by the lower flights of the endless chains, and during such movement distributes the concrete and levels, packs and smooths the same. They are inverted when they are transferred from the lower to the up er flights of the endless chains at the rear en of the machine, and advance toward the front of the machine in an inverted position, as illustrated in Fig. 1 of the drawings.

f When a car or carrier arrives at the front ot' the machine, it swings through an are indicated by the dotted line 41 and during such movement engages an arm of the catch 40. The movement of the car or carrier through the said arc at the liront ol' the machine returns it to its normal, upright or operative position, which it assumes in time to receive a charge of concrete from the hopper. The catch preferably consists olE a spring secured at its upper end to the exterior of the hopper, and provided with a lower engaging head 43, having an upper shoulder for locking the bottom of the hopper in its closed position, and provided with a lower beveled or inclined face to enable the bottom of the hopper in closing to automatically engage it. rl`he hopper is automatically closed by means of a weight 44, secured to one end of a flexible connection 45, which has its other end attached to the hinged bottom of the hopper. The flexible connection passes around a pulley 46, mounted upon tl exterior of one of the sides of the hopper. The weight of the material contained within the ho )er overbalances the wei-ht 44 and o vens the 1 )ottom of the hopper, and as soon as the material is discharged from the hopper the weight 44 quickly swings the hinged bottom 38 to its closed position.

The hopper is secure-d to a pair ol supporting bars or members 47, connected at their lower ends with the front horizontal shaft 4, and composed of lower inclined portions and upper vertical portions. rlhe lower inclined portions extend upwardly and outwardly, and tho hopper is secured to the upper vertical portions, which support the upper end of the elevator, as clearly illustrated in lligs. l and 4 of the drawings. The upper ends 4S of the supporting bars 47 are pivoted to the 'may be included in the series.

elevator, and the hopper' is provided with operating yokes 49, slid ably embracing vertical extensions 5l) of the outer bars or members of the front guides or ways 2. The yokes 49, which are disposed horizontally, are connected by a horizontal bar or member 49, secured to the hopper. By this construction the hopper and the upper end of the elevator are carried upward with the mechanism for spreading, smoothing and packing the concrete along the top of the wall. Motion may be communicated to the endless chains by means of an inclined belt or chain 5l, extending from one end ot' the iront shaft 4 to the top shaft of the elevator, but any so other suitable means may be employed for operating the machine. Vhen, however, the machine is driven from the elevator, the gearing for communicating motion to the machine, is not affected by the vertical movement of the machine incident to the building or molding of the wall.

Each car or carrier operates on the cement spread upon the wall by the preceding car or carrier, and in order to secure a uniform distribution of the cement throughout the length of the wall, the core is equipped at each side with a series of graduated Scrapers 52, consisting of blocks or pieces depen( ing from the top plate or member and gradually increasing in size from the front to the back of the core. Any suitable number of scrapers The core, shown in the accompanying drawings, is

equipped with front, rear and intermediate '.100

Scrapers, but in practice the Scrapers will be arranged at short intervals, say, about six inches apart. The front scraper removes a portion of the material from the car or carrier, the intermediate scraper removes another portion of the material, and the rear scraper removes the rest of the material. rlhe concrete is thus delivercc upon the top of the wall in a plurality of separate portions,

arranged at regular intervals, and the next T10 succeeding car operates to level, pack: and smooth the concrete. lt will thus be seen that the wall will be gradually molded, each car or carrier conveying a portion ol'v the material to the wall, and that the cars or car- U5 riers, besides operating to deliver the material to the wall and level, pack and smooth the concrete, also serve to automatically raise the machine as the wall is erected.

ln Figs. 10 and l] of the drawings is illusl' trated a modification of the invention, the core being equipped at each side with an inclined series of adjustable Scrapers 60, consisting of transverse slats or bars secured at intervals to the lower laces of the inclined V35 longitudinal straps or bars G1 carried by vertically adjustable pieces 62. '.lhe vertically adjustable pieces 62, which extend transversely of the top member 1S, gradually increase in size being progressively larger to support the series of scrapers at an inclination. The straps or bars 6l are secured to the lower faces 'oi the transverse pieces 62, and the latter are adjusted by means of screws 64, mounted in threaded perforations of the top member 63 and provided at their lower ends with ball-shaped heads, which are swiveled to the pieces 62, as clearly shown in Fig. 10 of the drawings.

In Fig. 12 of the drawings the transverse scrapers 65 are secured to chains 66 to form a ileXible series oi Scrapers for enabling different portions of the series to be adjusted independently of the other portions. rlChis construction is designed for use at points where spaces are to be lelt open for windows, doors, etc., and the scrapers at these points are adjusted so as to render themi nellective. The flexible series of the Scrapers will also operate to uniformly distribute the concrete at the places where the wall is being constructed.

ln Figs. 13 and 14 is illustrated a modification of the car, which is provided with inner and youter side walls 67 and rear doors 68, hinged at the bottom and yieldably maintained closed by springs 69, which permit the doors to be gradually lowered or opened by the Scrapers. rlhe bottom portions 70 of tne cars are tapered or wedge-shaped to present inclined laces to the concrete. rl'his will enable the cars to ride over the top of the concrete and will enable them to smooth, pack and level the material without clogging or causing the concrete to accumulate in front of the car.

Instead of employing a fixed molding frame, the machine may be equipped with a vertically movable molding frame 53, as illustrated in Fig. 8 of the drawings. rlhe molding frame, when vertically lovable and adapted to be carried upward with the rest of the machine, is composed of two sides, arranged between vertical guiding timbers 54. Each side is composed of three or four boards, in order to provide a comparatively light construction, adapted to be easily carried by the machine, but sides of any desired height may of course be employed. The sides are provided at their inner faces with horizontal rails or guides 55, which are engaged by rollers or wheels 56, mounted on the sides of the cars 57 at the outer faces of the contiguous side bar, as clearly illustrated in F ig. 8 of the drawings. The anti-friction devices 56 run beneath the sides of the mold and support and carry the same upward as the wall is molded. The sides of the vertically movable mold may be connected by any suitable means for maintaining them in spaced relation, and when building a wall in this manner, it will of course be necessary to operate so as to permit the concrete to set and harden before the sides of the mold are raised above the Sallie. instead of leveling',

smoothing and 'packing the concrete by means of the horizontal bottom troweling sections of the cars or carriers, illustrated in Figs. l to l inclusive, the cars may, as shown in Figs. 8 and 9, be equipped with transversely disposed bottom rolls 58, arranged to engage the cement at the top of the wall. The transverse rolls 58 are spaced apart to operate at opposite sides of the core, and the car 57 is also provided with supporting bottom sections 59, having their upper faces arranged in substantially the same plane as the tops of the transverse rolls and adapted to receive and carry the cement. The eniployment of the smoothing and tamping rolls does not interfere with the operation of the Scrapers in removing the concrete from the cars or carriers.
