' This invention relates to concrete building construction, particularly -to such construe# tion of the monolithic typevwherein the vvalls v are built up by successive pourings of concrete 5 that unite in setting. Itis concerned pri marily With devices for the building of such structures by the use of so-called slip forms,
y Y that is, forms which are gradually elevated as the Wall is built up, to afford -themolds forv v the successive pourings one on top of another..
The Ypresent invention is concerned prima# rily with thel construction of Walls in such fashion, With suitable voids or recesses for' the accommodation and `tying lin Y of floor slabs,
V'1.5, brackets, or other elements of the building structure Whichareplac'e'd after thel vvall is formed.
A general object ofthe invention is the p rov vision of certain improved devices which may 2Q be employed inconn'ec'tion with theuse ofslip'forms, Without involving changesjinthe construction ofthe forms or complications in their handlingand which Will'result inthe accurate and definite Vlocating and proper forming of, recesses and the like V for the ac-V commodation andityinginof other structural parts. f Another object is the provision of suchV de vices' by employment of which the amount of 3Q labor required will be minimized and'substantial savings effected in the'cost offthe construction operations. j l

Inone procedure followed in the buildingY of'monolithic concrete Walls, slip forms are' employed which formthe mold faces for the inner and outer Wall surfaces, and which," are elevated, step by step, after :successive pourings 'of concrete. 1 These slip forms are usually carried on 'jack rods which constitute reinforcing elements extending ver? tically in the Wall, said jack rods land the subjacent completed portions of "the Wall affording guidance for the forms such as to maintain them in a position-Where they will holdnsubsequentl pourings to continue the i Y I f over, to avoid interference .with'fthesystem- 'accompanying drawing Aforming a,

In Fig. 2 is illustrated a portion" of a joint' form Which is em lo ed Where desired as 7 7 Y an auxiliaryto the slip form, to provide a recess inthe Wall. This joint form `1s made up of top andbottom lplanks 14 connjected in parallel relationshipby spacers 14a` and having a length ofivire nieslr14b stretched across and securedto their l edges vonesidea Thns awtroughlike structure 1 is provided,
openfat thefront and havilngpa Wire mesh Wall atthe back, At suitable intervals the planksare provided with 'apertures 14C, for acconnnodation ofreinforcing or tie rods. rl`he Wall 10 having been built upto jan-relevation Where it'V is desired to form av recessfjoinjt forms of the sort just described arey placed 4*within the mold space between the formY panels 11 and 12 and, in the event the recesses are for the accommodationl ofV floor slabs,y
saidjoint forms are arranged'in the proper level disposalfand Withv their-*open side iir contact with the linner forni panel. For a floor joint, thesefjoint forms may be of 'such Width .that they extend for'only a. part ofthe Walls thicknessthe mesh side 14b thus being within the cross sectional area :of the Wall.V Reinforcmg or tlefrods 1.5extending;verv-l tically in theW'all, are accommodated bythe Nmains -1 apertures 14C,y said. rods-` being placed "either before or afterthefpositioning of the 'joint forms and being partlyl imbedded in the concrete; whereby they hold the `joint form against the form panel. Whelrth'e joint forms are thus suitably place'd',`the next pour-v ing of concrete is placed `betwcen'tbe form panels 11 and' 12,] the jointv form being enveloped therein at'tlietop'and on the ,screen side.v The Wire mesh is of such size 'as Vto prevent the flow of the concrete'therethrough:
to any` lappreciable extent. However, l some o f the finer or morefluid partsofl'the mixture do penetrate'the screen', bonding it into'v *thev concrete, n and holding iti l definitelyin place",l thusvcounteracting'the tendency of thek jointfo'rinrto fioat out of placeintheuconv-`v Crete Wl11the-latfe1f `isiplastic .Whenljthef nen* pouring isset vs1 i"flicie' I'itlyg'and thje'timej comes toelevalte fthevslip ,frm,' suchV ils'zgac conifplished inf lthe iisiialfashiom v Wit'lijoiitjto the Vdesired height,Y the planks 14 and of' the VWall, With t-he rods"15 expose'din the` recesses for the connection of tying reinforcetalents of a-1oor1s1ab h' W tobe poured. 5, In Fig; 3 is illustrated an arrangement of ichis subsequently` jointform forlforming the recesses completely through the Wall, as for the accommoda'tion of a'loor bracket.y This joint form is built of boardsas a rectangular open sided box;V one of the 'side boards being illustrated at l'and' the endboards at lThe lengthVA of they latter is -such as 'to equal'the thickness of thejjvall, jandftheii" Widtl'rissuchl isl n necesser'yjf: the Widtlro'fgtlle recess'- The end boards arefrrordd with. apertures" 17?.

A
further very important advantage lies in the j readiness with Which the joint forms may be removed after the Wall has set. The Wrecking or tearing out of these joint forms is a procedure requiring hand labor, and if such forms are vdilicult of removal, 'may'involve considerable expense. The joint forms herein disclosed have the advantage of being very easily removed, aS the spacers may readily be knocked outand the boards pried loose from the concrete and split longitudinally to free them from' the rods. This advantage appears particularly in the case 1 i' of the ioor joint forms, Where it is necessary simply to remove the spacers and the top and bottom planks, the screen, which form the back retaining Wall of the recesses, being lett bonded in the concrete.
wWhat I claim is: l. As an v article of manufacture, a joint form for concrete construction comprising a trough-like frame having oppositely disposed Walls formed of planks provided with longitudinally spaced apertures, and a Wall of Wire mesh conjoining margins of said oppositely disposedvvalls, said Wire mesh being of a size to retain concrete mixture.
2. A joint form for concrete construction comprising a three-sided trough-like frame, the opposite sides of theframe being formed of planks spaced apart and connected in parallel relationshi and the third side being formed of Wire i'abr-ic conjoining said opposite sides and of a mesh size eii'e'ctive to retain concrete mixture from passing through into A the space between the planks.
.Y scribed my name.
3. A joint form for concrete construction comprising a trough-like frame having opposite sides formed of planks malntained 1n a denite spacedrelationship and a third Wall formed of Wire fabric stretched between said opposite sides and of a mesh size eii'ective to dam unset concrete mixture.
4. Means for concrete building construction comprising, in combination, form panels arranged in opposite disposal to afford mold faces for a Wall, a oint Jform arranged between the panels Within the cross sectional Y area of the Wall, said joint form having oppositely arranged sides spaced apart and positioned With their margins against one of the form panels and a Wall portion formed of wire mesh stretched bet-Ween said Wall portions and spaced apart from said panels, and rods extending through the joint form between said panel and said mesh Wall. s
In testimony whereof I havehereunto sub- WILFORD R. sPRoUL.
