Application'filed April 2, 1919. Serial No. asaew.

primary object to provide a'mold for concrete steps embodying readily adjustable gages whereby steps of various heights and widths may be accurately and uniformly constructed.

A further object is to provide an adjustable mold or form which may be conveniently adjusted and positioned for forming flight of steps in which such steps have treads and risers of anydesired dimensions.

A still further object is to provide a device of the character mentioned by means of which is obviated the large waste of lumber commonly entailed, and the time lost, in cutting and fitting timbers for concrete step forms to meet the varying requirements of successive jobs of Work.

With these andother objects in view, the invention resides in the features of construction,arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1' is a view of the invention, partly in section and partly in side elevation, illustrating its application Fig. 2 is a top plan view of the same;

Fig.- 3 is an enlarged detail elevation of a fragmentary portion 7 of one of the step gages. l 1 l Fig. 4 is'an enlarged section onlin'e l 1, Fig. 3; 7

Figs. 5 and 6 are enlargedsideelevations of the lower and upper endportions, re-

spectively,'of the inclined supports; and- Fig. 7 is a section 011 line 7-7, Fig. 3. Referring to said drawings, in which like designating characters distinguish like parts throughout the several views f A indicates generally each of two opposite supports adapted to be disposed at any inclination whiehit may be desired that the flight Each of said supports comprises two

parallel memhers

1 and 2, the former superposed over the" latter, at a distance therefrom to provide an intermediate narrow slot-like passage or runway 3. The lower ends of said

members

1 and 2 are rigidly attached to an angular arm. 4 having a vertioal eye 5 formed therein for a groinid enterhig peg-t1- stake 6 by means of which the lower may be held in position; An arm 7 having a form somewhat similar to that of the arm 4- and having the upper ends of said members similarly attached thereto isprovided with "an eye 8 for thereceptionof a peg or end of the support stake 9-by which the upper end of the sup- I port may be secured in place.

a A pluralityofstep gages, the number of which will vary with the number-of steps to be constructed or with the length of the supports-A which are employed is provided 1n association with said supports, each being adjustable to conform to the dimensions required for the steps. Each step gage com prises a post-like support 10 adaptedto be disposed against its rear edge the outer face of a riser board 11. Said post 10 has in the upper end thereof a vertical slot 12 of appropriate length, through which is directed a bolt 13 by means of which said post is attached to the adjacent support A. Said bolt is directed outwardly, first through the runway 3 of said support A, thence through the slot 12 of the post 10, and finally through a lug ltcarried upon the outer end of one of two alined threaded rods 15-and 16 which, together with an intermediate turnbuckle 17, constitute an adjustable brace whereby the upper end of each post 10, except the uppermost of the series employed, is spaced from the lower end of the next post 10 thereabove.

Said bolt 13 preferably has that portion 13 of its body which is adjacent to its head 13 of rectangular form in cross section so that,

while it may be moved to any desired position along the runway 3, it cannot be rotated in said runway. Fromsaid portion 13 to its point said bolt is of cylindrical form, as shown, and has a threadedend for the reception of a nut 18 whereby the relatively adin vertical position and to receive -posts 10 with respect: to the: The adjusted position of the istering holes provided in said members for said bolt of a form and size corresponding to that of the body of the bolt. r

In practice, when the supports been properly positioned, the various step gages are ad usted to the dimensions of the" steps which are to be constructed This adjustment is effected, first,

lengths of the braces, in accordance with the required width of the treads of the steps, thusaccurately spacing the foot of each post 10 from the post next therebelow, and, second, by making vertical adjustment of said supports I A. parts will be maintained upon tightening the nuts 18 upon their bolts 13. v r V Each post 10 has formed on the. lower end thereof a jrearwardly extending toe 21 which constitutes a seat upon which'an end of a transversely disposed riser board 11 rests, such endpreferably being provided with a suitable recess 22 forithe reception of said toe.

As is obvious,.there may be made any desired adjustments within the limits allowed by the size of the parts composing the step gages. I

Any appropriate form of said plates or cheeks 23 may be employed in the construction of the form.

What is claimed is- 1. In a form for concrete steps, a plu- V .ralityof adjustable step gages, each gage comprising an upright post having a longtudinal slot in the upper part thereof, said post being adapted to have a riser board seat thereagainst, and a brace pivotally connected to the lower end of said post and adaptedto space the latter from the correspondingpost of the next subjacent gage, said vbrace being longitudinally adjustable and having at its front end attaching means receivable in and adjustable along the slot of thepost of said subjacent gage.

2. In a form for concrete steps, apluralityof adjustable step gages, each gage comprising an upright post having a longitudinal slot in the upperpart thereof, said post beingadapted to have a riser board seat thereagainst, and a brace connected to the lower end of said post and. adapted to space the latter from the corresponding post of the subjacent gage, said brace consisting of two alined threaded rods and a turnbuckle adjustable on said rods for varying the reach thereof, the forward end of'said vbrace being adapted to be adjustably mounted intheslot of the post: of said subjacent gage.
