APPARATUS FOR CONSTRUCTINY'G CONCRTE MANGERS.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed July 8, 1915. Sera1No.f38,648.

easily made of uniform sizes and shapes and' the different parts of the mangerand other concrete work will be more securely united together, which results will be attained by the expenditure of a minimum amount of time and labor; and it consists of the employment of certain forms and appliances constructed and used as hereafter described to accomplish the results herein set forth.

In the accompanying drawings forming a part of this specication, Figure l is a perview of the latter.

spective of a series of cow stalls having a partially constructed manger provided with appliances, embodying my invention. Fig. 2 yis a transverse section running through the partially completed section of the manger, substantially on the line 2 2. Fig. 3l is an enlarged perspective of a portion of one of the appliances. Fig. 4c is an enlarged top view of another appliance. Fig 5 is a side Referring to the drawings, A represents the'top-rail, B the stall posts and C the partitions of a series of cow stalls. These parts comprising the stalls are set up on the ground and are connected together inthe usual manner as shown. `After being propiv erly lined up to make the row of stalls stand plumb and true, boards D and D are set up on opposite sides of the Vlower ends of the posts B tomake a form or mold' for the manger curb E, which is made of Vconcrete placed while in a plastic state between the boards D and D.

The boards on both'sides are supported in position'by stakesxS -driven in the ground, the stakes on the rear side being hidden from view by the boards in Fig. l. It is preferable that a space of several inches be left A between the lower edges of the boards and the ground so that the plastic cement or con-A crete' will run out under the boards to some extent and spread on the gro-undfor a short distance so as to form an enlarged base for the curb, which is built rst as shown by Figs. l 2.I Besides making a broader base for the curb it will also make roughened sloping surfaces which will adhere better to the concrete thereafter added.

It is important that the boards D and D be spaced apart equal distances on eachV side of the posts B so that the posts will stand directly in the center of the curb and not be set to one side or the other. To facilitate this central spacing I use devices F which may be called curbVV gages, enlarged views of which are shown by Figs. 4 and 5. The

upper inner edges of the form boards D and D. fare placed against the outer faces of the downwardly projecting lugs or shoulders f and nails or screws may be driven through the holes in the ends of the gages the boards in this position.

Laterally projecting lugs g spaced apart so as to embrace some of the stall posts B are formed on the central portions of the gages. These lateral lugs being equal dis-l tances from the adjacent depending lugs'or shoulders j", the boards D and D will jbe held a uniform distance from each other and equal distances from the postsl B. No cutting ofbracin strips, nor measuring or fitting as was. formerly needed will be required to get the' parts in their properplaces. It is preferablel to have laterally projecting lugs on each side of the gagesl and to have the lugs on the opposite sides set 'different distances apart so the spaces be-V tween them willV correspond with the different sizes of the material that may be used for the stall posts.

In Fig.v 1, the 'section of the stalls at the right-hand end of the drawing (the fourth section from the left-hand end) shows the form boards D and D in place ready for the placing of the concrete for the curb, while the first, second and third sections from the left-hand end show the curb completed and the form boards removed. The rst section at the left also shows themanger I lconnpleted; the second section shows the manger` to hold partly completed, andthe third `section shows nothing donetothe manger exceptthe completion of the. curb E and the set` ting up of a'portion of VVthe 'manger fr-oml ger as 'shown by Fig. Tlls'f'lfimgemeli) I" Y also insures a better joint between the man-'i ger and concrete floors which, though not shown, are usually built adjoining the curby which nails or screws may be driven to hold the upper ends of the templets on the upper edge of the form board H. The lower ends of the templets are preferably set Yin recesses or pockets N formed in the adjacent edge of the curb E which is built first as plainly shown in Fig. 2.

Y One or more pairs ofthese bent metal bars or templets are thus placed according to the length of the section of the manger/to be built at the same time. The plastic cement is placed in position until it is Veven with or a little above the upper edges of the templets Twhen it is smoothed oft' even withk their upper edges by means of Vastraight edge. The workman stands outside of the form board Hand draws the straight edge to him.

If the cement is soft and will not atfirst stand in its proper position at the upper edge of the manger, theworkman can continue'to draw it up toward him until Vit has stiffened sufficiently Vvto stand; or if preferred he can clamp Va thin board or sheet of metal upon the upper portions of the templets to hold the cement in position until it has stiifened sufficiently to stand alone. When the cement has stiened suiiiciently to stand, the templets arey removed and the small recesses or grooves formed bythe templets, as well as the recesses or pockets in the curb, are filled with cement by means of a trowel or otherwise, and the face of the man- Y ger is troweled smooth and made continuous, as may be required.

It is essential that the upper edges 'of the bars T be Vbroadened'to give them suicient lateral strength and to cause lesswear on-the straight edge which is lused to form kthe interior surface of the manger, also, to secure suliicient vertical Vstrength Vwithout eX- tending the dimensions of the bars downward to any considerable extent. The 1recesses Voccupied by the bars having to be filled it is advantageous to have them as shallow as possible. A T shape with the head on the upper side is ythe preferable form for the bars, but other shapes 4may be used having a laterally extended upper sur- Vlouter `end of the bars doesaWay-Nvith the vor.

and hold the lower ends of the bars or templets, it is advisable to nail or tack a strip K on the inner side of the form vboard D" as shown by Fig. l. This strip will form a con i tinuous groove in the side ofthe curb adjacentV to the inner face of the manger fas; shown 1n Crossfsectionjby F 1g. 2,'and .Willi Y insure the placing of thelower ends ofthe templets in line with each other. It'will also 1 form a more substantial jointV between `the Y cement ofthe curb and the body of theV manger.V Without this groove there would probably be a perpendicular Vseam Vwith aYY feather edge oint between Vthe Vcurb and Vthe tionable.

Y This defect Vwill .be @maar ty flani'ngV f the groove in thesideof the curbfbymeans of the strip K tackedo'n the? Vform board D. This will thicken .what Ywouldotherwisebe Y Vbody of the-manger .which would beV objec- Y Y' a feather edge of the main'part of the man- 4 ger adjoining lthe previously {eonstructed V Y sideof the curb, and it VVwill make Va horizon curb by extending it Vintofthe-groove .in the tal instead of a vertical joint.

Fig. 1V shows a different' step in thecon-Y il 'Y struction of theV manger in each of'thefstalls,V Y' y Y 10o'V u but in .actualV operation the same step is usually continued ythrough afsectlon of four or more stalls at the Sametime: The .objectV of the drawing is to illustrate thefdiiferent steps in the. minimtunfof-spaeeforithe drawing. After the manger is completedthesstall floor and other Vfloors adjoiningit may lbeVV added in'theusual manner, but these .operai- .j

tions are not shown inthe drawings;

Fig. Vl shows cut-outsii'n the manger Where Q. Y

the stanchions, (not shown) are usuallyan-Y chored. These cut-outs-are preferably made by cutvout forms Mset Vin between 'the form boards l)y and D and which are the subject"V Y' of another application. The ftemplets may 115 Y be readily made to fit any size and shapeof manger andY theplate 'P being'bendable may be readily bent to fit-and stand horizontally Y on the upper edge of the form boa-rdsV when different-widths of'boardsare used to .ma-keVr Y V the outer Tedge of the manger of different heights.
