WALL FORM OR IEOLD.

Application filed May 28,

To all whomit may concera:

Be it known that I. CHRISTIAN BnYNoLDT, a citizen of the United States, residing at Pittsburgh, in the county of Aliegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wall Forms or Molds, of which the following is a specification.

This invention relates to wall forms for making concrete walls and the like, and has particular reference to a buttress wall mold or form. I

' One of the primary objects of .my invention consists in the provision of an improved wall form of such character that it may be utilized to form buttress walls, such for example as reservoir walls.

Another object of my invention consists in the provision of an improved wall form, by means of which I am enabled to construct leaning walls whose tops overhang their bases, or inclined walls.

' provision ofw Still another object of my invention consists'in the provision of an improved wall form of such character that it may be readily accommodated to construct walls of different slopes or inclinations or having different tapers.

My invention also contemplates the pro of rigidity, while at the same time it is adjustable to permit of the attainment of the foregoing objects. 1 r

In general, my invention is directed to the art may be termed, a collapsiblc wall form.

I accomplish the foregoing, together with suchother objects as may hereinafter appear, or are incident to my invent-ion, by means of a construction which I. have illustrated in preferred form in the accompanying drawings wherein:

Figure 1 is a transverse section through my improved wall form with the parts in position for the casting of the concrete, the section being taken on the line 1.1 of Fig. 2; Figure 2 is an irregular section taken on the line 22 of Figure 1; Figure 3 is a section taken on the line 33 of Figure 1 and Figures t, 5 and 6 are sectional views illustrating details of my invention.

Referring now to the drawings, it will be seen that in general, the apparatus comprises Specification of Letters Patent.

and to .be shifted longitudinally thereofon rails 7 a' front wall mold section B adapted to be supported from the traveler a swinging framework C,.also capable of support Fatented A r. 25.1922.

' a traveler A, adapted to straddle the work,

from the traveler; a rear wall mold section D and adaptedto be carried by the framowork G, and cooperating withthe section B; buttress wall mold sections orbnlkheads E, also. adapted to befsupported from the'framework C and the lower buttress mold sections or bulkheads F. The moldsections constitute a collapsingyself supporting W ll form which'may be used with the carrier as a unit to be shiftedto cast the successive. sections of the wall. 01' the traveler may be used with a plurality of such mold forms to carry out what may be termed a telescopic method ofoperation in which the traveler be utilized to set up the forms and to shift'or telescope each form'outside theother forms to a newcastingposition." The invention" will first be described in connection with the unitary operation ofthe traveler and certain of the mold sections. v

The traveler A comprises. a top; section a,

preferably in the shape of a rectangular frame composed of suitable channels 8 and connecting angles 9; and two side sections and braced by longitudinal structural members, such as the members-10 and 11. The upper corners of the side section a?) are braced by the angles 12, and thesidosecor limbs 12, and 0, each side" section being; composed of apair of truss.es,'suit ably spaced;

tion a is bracedby diagonally disposed rods 1?; (see Fig. j

Theside section b, is preferably secured to the upper section of thejtraveler, while the side section a is hinged-or pivoted thereto in the manner. matically at 14; in Fig. 1. The purpose of hinging the side section etc the top of the carrier is topermit of adjusting .the angular inclination of the section so that the apparigidly indicated diagramratus may be utilized in building walls of I different inclinations or tapers, or in constructing center walls. To this end, I further provide both the top. section and the side section a, at various points, with a .plu-.

rality of holes or apertures 15 adapted-to receive locking pins (not shown) by'means of which the side sect-ion will be supported in any adjusted position with respect to the top section. At" the corners, Iprovide the side sections with flanged wheels 16 adapted-Q g V V 1,413,705

to engage the rails Z, the flanges serving to sufficiently support the side sections against lateral displacement under ordinary conditions of service.

The wall mold section B comprises top and bottom rails or beams 17 and 18, the vertical angles 19, secured to the rails 17 and 18 in the manner shown in Figum 1, the horizontally disposed wales or nailing strips 20 adapted to carry the lagging 21. The mold section is swung or suspended from the top of the traveler by means of jacks 22 and it is supported from the side section 0 by'jacks 23, by which arrangement the wall mold section is supported adj ustably but securely with reference to the side section 0 of the traveler, and in such manner that the mold section may be adjusted as to its inclination and to the thickness of wall to be constructed, and may be collapsed from the work after a section of the wall has been cast and has set in order to permit the traveler to be shifted to a new position. In collapsing the mold section toward the side section 0, it will be apparent that the lower end of the mold section will be cleared from the ground.

Referring now to the swinging frame 0, this frame is composed of upright truss members (Z composed of suitable structural members such as angles or the like, the trusses being spaced and braced by connecting, longitudinally disposed channels 24 and angles 25, or similar structural members. The wall mold section D is composed of lagging 26 suitably secured to nailing strips carried by the frame C. The frame C is swingingly mounted from the top section of the traveler by means of jacks 27 which have pivotal connection both with the frame itself and with the top section of the traveler. The frame U, with its wall mold section D, is supported and. braced in a manner to be hereinafter described.

As herei'nbefore indicated, the buttress forms or bulkheads, constituting a part of o my apparatus are made in two sections. a-

lower section F and an upper section E. The lower sections F are each comprised of longitudinal beams 28; the nailing strips or wales 29; and the lagging .30. In setting up the lower buttress formsF. the pairs of forms may be connected at their outer ends the detachably mounted spacing and bracing channels 31 (see Figure 1) or other wise braced. At the front the pairs of lower buttress forms are preferably spaced apart by the lower wall section G. composed of suitably framings carrying the la gginp; 33.

The upper buttress wall mold sections E each comprise a framework of structural members such as the angles 34 and the beams or wales 35 (see Figures 2 and which carry the lagging 36. A pair. of such buttress wall sections Eare carried by the frame 0 in such manner that the sections may be collapsed toward one another. This is accomplished by supporting the sections. from the frame C 'by means of pins 37 passing through. slots 38 formed in the longitudinal channels 24: of the frame. 'ihe sections are adjusted, i. c. advanced or retracted by means of the jacks located near the top of the frame C and the jack h) which is secured to the framework of the mold sections in the manner indicated in Figure 2.

The corners formed by the buttress sections E and the wall section D are closed by lap joints of the construction illustrated. in i ure 5, from inspection of which will be seen that at the forward edges the but tress sections are provided with beams or strips tl over which are secured the an -2 plates 42 adapted to lap over the lagging 26 of the wall section D. The corners formed at the top are also closed by a lap joint of similar construction (see Figure 6). i y the provision of these joints the corners of the mold forms are closed so as to properly form the corners of the wall and buttresses, while atthe same time it will be apparent that they do not interfere with the collapsing of the parts.

The operation of the parts is as follows.

The frame (I) carrying the'wall mold section D and the collapsible upper buttress mold sections E, is swung to the position indicated in Figure l and there supported by such means as the tackle mechanism 45. The wall section and the lower buttress forms F are now placed in position and properly braced. after which the frame C is supported and braced by suitable means, such for example as the horse or truss and the wedges 4-6, or the braces 4-4 (see Figure 1) or both: and also by the beam 50. as will appear. The buttress sections E are braced by tightening the wedges 4L7 which are inserted between the upper and lower butt-res. sections the gap between such sections be ing covered over by the plates 48 secured to the lagging 35 of the upper buttress sections Figure 4;). v

The other buttress mold sections cooperating with those carried by the traveler to form the but sees, are nowset in position as indicated by the dotted lines in Figure 3 and are secured in position by means of tie rods 49. or the like. diagrammatically indicated in the drawings. The ends of the but tress sections are preferably closed by end plates such. as shown for example in Figure 5%. The weight from the trusses or rather from the frame C, is transmitted. to the buttress frames or sections by means of the beam 50 supported from brackets secured to the frame work of the buttress sections and wedged in position by tlie'wedges 51, as shown in Figure 2. V

' The section of the wall is new cast and after the concrete has set, the tie rods 49 are first removed, which permits of the removal of the lower sections F of the buttress form, after which it is possible to collapse the buttress sections E, free of the concrete, by means of the turn buckles 39 and the jack Frame C and together with. it, the wall section D and the buttress sections E may now be shifted or swung rearward to the dotted line position of Figure 1, by'means of tackle mechanism shown, or by other suitable mechanism, and the wall section B may be retracted in the'manner previously described, by means of the jacks 23. The traveler may now be'shifte'd to a new position and the parts positioned for another casting operation.

It will be seen from, the foregoingthat I have provided a simple apparatus whereby I am enabled to cast a sloping wall, such as'are suitab e for reservoirs,dams and the like; and that the apparatus may be readily adapted to build walls of different inclinations and tapers. It will also be apparent that the form may be utilized in casting center walls by the substitution of the proper form of wall sections, in which connection it is to be observed that the mold sections shown may be readily detached and others substituted therefor where necessary. Furthermore, the collapsing of the parts can be readily accomplished, and all of the parts when assembled constitute a rigid form. lVith regard to the collapsing of the mold form, it will be observed that the side section I) of thetraveler while it its open to permit of the retraction of the frame C and the buttress sections E, is nevertheless sufiiciently rigid. because of the truss construction employed which is of considerable width at the top.. (See particularly Figure 1.)

Referring now to the telescopic method of operation, i. e. the use ofthetraveler with a plurality of mold forms, the apparatus is employed as follows 1 v The traveler A is used as a carrying memher to set up the forms, for the forms, as

will appear, are self-supporting when set up and it will be obvious that the tackle mechanism and thejacks 22, 23 and 27 can be readily detached from the mold section to which they are respectively attached at one end, as a result of which the traveler may be utilized to set up any desired number of wall forms. 1 r

7 It will be apparent that the mold sections D,.E, F and G, are self supportingwhen'set up in the manner previously described, and

the mold section B may be readily supported from the other sections by any preferred means and detachably secured in po-- sition by connecting elements, such for example as the tie-rods 60, which may be removed preparatory to collapsing the form. When it is desired to shift any of the mold forms, the traveler is. brought into position and properly coupled to the mold section,

shapes difl ering from the buttresses shown. I The term buttress, therefore, is employed. in the specification and claims -hereof 1n a broad sense.
