I 8 Claims.

'This invention has as its'principal obj'ect'the provision of 'animprove'd T-head shorehanger such as used in'the building and construction arts for attaching shores to forms while adjustment is made at'the base'of the shore.

The improved T-hea'd' shorehanger'is in the form of a metal plate having oppo'siteliollow arms and depending flanges in "juxtaposition to fit onto the head of the shore'and further'provided with spaced slots for engaging the hanger with'hanger bolts or nails in the forms, the hanger having other formations for receiving wedges by means of whichcertain; parts of the form may be firmly secured in position at points adjoining the T head.

Viewed from another aspect, it is an object of the invention to provide an'iinproved T-head shore hanger consisting of a'metalplate bent back upon itself to provide'fiatsleevesof rectangular cross section'with opposite depending flanges to engage the shore head andcertain openings aligned in'the top and bottom'faces of the plate to receive wedges, together with formations for engagingthehead with hanger bolts or the like on'theformto maintain the shore in position untiliadjustment can be-made at the base.

Other objects, advantages and novel aspects of the invention reside in certain 'details of construction as well as'the cooperative relationship of the component'parts of the illustrative embodiment described hereinafter --in view of the Fig. 1 is a planview of the stamped plate from which the hanger is'formed;

Fig.- 2 is a perspective of the shore-hanger in exploded'relation to the shore and form;

Fig. 3 is an enlarged 'verticaltransverse section through the hanger along lines 33 -of Fig. 2;

Fig. 4 is a longitudinal sectionthrough the hanger in operative position drawn to enlarged scale;

Fig.6 is a vertical cross section of-the-hanger as seen from line5-5 in'Fig. 4;

"consistsof a metal plate turned back uponitself to provide substantiallyfiat opposite sleeves -I having'atop face I I and albottom faces IZ-with "oppositevertical side walls l3-from=each ofwhich depends a' fiangel4 adapted tofit over the head block on a Shore [6 which is moved into sup- 'to the latter by welding or the like as at 34. reinforcing beams 30 are so disposed that the porting position beneath the bottom-of "a form to receive cement or the like-l8 in the formation, for example, of'a beam or-a combination beam and floor slab.

The customary'practice inthe'building arts -is to attach the'head blocklB by-'means'ofstraps 15a to the tops of a-pair'ofshore timbers [6, the

'T-head hanger being'fi'ttedpntotheblock "as aforesaid and held'in'positionby means of a wedge peg I9 (Fig. 4' also) which is driven through the flange openings beneath a block ZIat the top of the shore.

When the hanger is thus in position, it" ishung from the beam 22 of the form by'means of headed hanging elements, such as nails, 23 ('Fig.""4= also), the heads '24 of which are adapted tobe fitted into theenlarged'edgewise openings25 in apair of transverse slots'26 formed in'the' top 20 is suspended from the bottom'of'theform I1 until thebottom (not-shown) of the shore'may be jacked up to take part of the lead.

.A feature of the improved hanger structure resides in the provision of reinforcing means in the nature of T beams (Fig. 4),'the cross web 3l of which is fittedagainst the underside of the top H of thehanger and secured thereto of the bottom plate I2 of the hanger and secured The cross webs 3| thereof-will "support a maximum portion of the load in the region "where-there would be the greatest" weakness to 'a" bendingmo- 'ment, that is'to say, at the'point where the mounting flanges H are formed on the plate, this bending moment being further'suppresse'd by the disposition of the main web portions'33and their attachment 3 34 with the bottom faces "of the hanger.

-A further feature of the 'invention'relatesto the provision of wedge receivingformations in the nature of aseries ofholes-36' (Fig. 1) in the top plate II and correspondinghol'es 36 inthe tomove in a horizontal direction as a result of driving the same into any givenset of paired holes in the upper and lower plate portions, as

illustrated in Fig. 4, for example.

Once the pegs 31 are in position, they may be smuredagainst accidental dislodgement'in the manner illustrated in Fig. 6- where there is shown a cast iron peg. 31a. provided with a transverse hole 31b in which a retaining pin, such as, a nail,

40 may be disposed. If the pegs are made of wood, the retaining nail may be driven therethrough, or the holes 311) may be preformed therein.

Relative offsetting of the companion openings for the pegs is accomplished by having one of the openings mm (Fig. 3) of lesserwidth than the companion opening 2!], as illustrated in the vertical section taken through the attaching flanges, which are intended to be secured on the head block I5 by the peg l9 (Figs. 1 and 4:). ihe same principle is-applied to the

openings

36 and 36, as shown in the plan view of the stamping 'of Fig. 1 representing the condition of the plate be fore it is formed up into the completedhanger shown in Fig. 2!.

r In the formation of the bottom Wall I2 the two edges l2 are spot welded at intervals and vinv the presentfembodiment there is a rib l2 pro 'vided by the joining edges, which rib 42 constitutes a reinforcing for the sleeve IE and is ,welded to the web 33 of the T 38 :as before stated.

The various advantages and objects of the in- .vention may be accomplished by modifications of .the particular embodiment specifically described herein, and it is intended that the appended claims shall include all equivalent arrangements fairly coming within their call.
