This invention relates toimprovements in shores, and particularly to that kind of shore which is used for supporting forms for concrete floors and the like.

The principal object of the present invention is to provide a simple and inexpensive construction whereby the range of adjustability of an adjustable shore may be considerably increased.

A further object of the invention is to provide a shore having a frame adjustable on a support with a. head bearing member which may be readily and quicky removed from the frame and another of a different length quick- 1y substituted therefor without the use of special tools.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the specification.

In the drawings:

Figure 1 is a front elevation of an adjust able shore showing one way of carrying out the invention applied thereto;

Figure 2 is a transverse section taken substantially on line '22 of Figure 1, and look- Figure 3 is a fragmentary side elevation of parts shown in Figure 2;

Figure 4; is a perspective view of one of the brackets for retaining the head bearing memher on the frame;

' Figure 5 is a perspective View of a supporting member for the head bearing member;

Figure 6 is a section on line 66 of Figure 1, and 7 Figures 7 and 8 are perspective views of a slightly modified form of bracket.

Referring s ecifically to the drawings in which like re erence numerals refer to the same part in all the figures, 1 is the base or support of an adjustable shore of well known type and construction. This post comprises a tubular upright member having a spreader 2 at its upper end which is slidably engaged by the side members 3 of a frame. The spreader 2 has outwardly extending lugs being in the direction of the arrow at said line;

tween whichsthe sidemembers 3 are guided in their vertical or longitudinal movements.

'The side members 3 have clamping members fl mounted on their lowerenols which extend inwardly and are pivoted together insuch a manner'as to clamp the post 1 between them to support the frame thereon. The construction is such that when the side members are raised relatively to the post, the clampingv members are disengaged therefrom, permittmg the frame to be moved longitudinally relative to the post, but when the side meming bracket 5 showninperspective in Fig- 1 ure 5. This supporting member or bracket 5 may be formed of sheet material, andcomprises a horizontal supporting wall 6'substantially square or rectangular in form, and on opposite sides has downwardly projectmg flanges 7. These flanges 7 maybe provided with openings 8' whereby the support is secured in the frame by means of bolts, although it might be secured in the frame by any other suitable means." The opposite front and rear edges of the supporting member are provided with upwardly projecting flanges '9adapted to engage thesides-of ahead bearing member'lO resting with its lower'end on the support 5 and serve to retain the head member between the side members '3 of the frame. j Y r I The side members 3 extend above the support 5 and at their upper ends each is provided with a bracket'generally referred to by the numeral 12. Since these brackets are similar in construction, except for being right and left, a description of one will suflice. Each of said brackets comprises an outer wall member 13 and an-inner wall-member 14 integral therewith but spaced therefrom to form a channel between them. These inner and outer walls engageopposite sides of the top of the side members 3 to which they'are. secured by any suitablemeans, as .bybolts member which lies between the inner and outer walls of the bracket, and the member.

or lug 16 projects forwardly and outwardly over the front wall of the side member. By this construction, the bracket is readily and :quickly positioned on: the side member of the frame.

- The bottom of the head member is seated on thesupportfi between the sidemembers and the flanges 9 on the support, which fixes it against movement in all directions horizon'tally. The member 10 extends upwardly from this support between the side members 30f the frame andvertically above said side .members, and atits top has secured theretoahead 20 ofany usual or well known vconstruction. The rear wall ofthe head supporting member engages the inwardly 'pro- ,jecting flanges 15 of'the brackets 12, as shown in Figure-2', which retain it from rearward .movement from the frame. Secured to the front wall ofthe' head .member at-a point oppositethe flanges 15 by means of a bolt or ..otherwise is atie member 21 in the form of a strap preferably .formed'of sheet material,

. andwhich projects laterallyover the front .wallsof the -side members 3, asat 22. :Each

of the projections'122is provided with an opening through which the corresponding projection orlug16'on the-associated bracket -14 is adapted to project.

, Suitable means are providedfor securing .the tie member to-the bracket 12 to prevent forward movement thereof and the head bearing member 10 engaged thereby and to which itis secured. In the embodiment illustrated herein, said means comprises wedgeshaped members23 adapted. to be inserted in openings provided therefor in the projections '16 and. to engage the front wall of the tie .member21and secure it and the head member in the frame. Vertical openings are .shownin the projections .16. .However, they may extend ina horizontal direction or additional .h'orizontalopenings may be provided sothatFthe wedges may be inserted in a horizontal direction. In thisposition, they may be "readily removed or replaced when the :s'horehead andforms supported thereon are positioned as near as possible to the top of the frame. 7 p

1 From the preceding, it will be understood that the extension orhead supporting mem ber '10i1can'rea'dily be demounted' from the frame "by. removing the wedges 23 from the projections 16. The head supporting member with the tie bar 21 can then be inclined forwardly from the flanges 15 and removed from the frame 3 and support 6. By this means, a new extension head member of the side members and to which the tie member :21 may be secured. By providing'extension head members of different lengths, it is possible to secure shores of a widerange of heights or provided with different types of heads, all using the post and frame of standard adjustable shore.

. In order to prevent loss of the wedges 23 and to have them convenient foruse when mounting a new extension member on the frame, they may be secured to-the ends of suitable flexible members,.such as the chains 24, the other ends of whichuare secured to rings 'or hooks 25 conveniently provided therefor on the outer walls of the brackets 14.

To secure the extension member against lateral movement or vibration'in the shore frame, bearing members may be provided therefor.

In the present embodiment such bearing membersare shown i'n'the formiof angle irons 26. The angle irons 26 are secured -to the members-3 of the frameand project inwardly between said members and the extension member 10. It will thus be seen that these angle irons'prevent movement of the ex tension, member in'one direction and the.

base of the head bearing-member and the side 7 members of theframe. This could-be done by cutting the flanges 7 andbending portions in opposite directions to provide both upwardly and downwardly projecting flanges.- 1

. In Figures 7 and 8 slightly modified forms of brackets 12 are illustrated. These are similar, except that like the brackets 12 they are right and left,fand only one will be described in detail. The brackets 12? are preferably constructedof sheet material and'each comprises an outer wall 30 and an inner wall 31 spaced therefrom but connected therewith by means of a spacing wall 32. By this con- 'struction, the walls 30=and 31 are connected with opposite sides'ofth'e wall 32 and ar ranged substantially at right angles thereto. The innerand top wall-sare extended forwardly to provide a projection or lug 33 having a top wall 3% in the planeof the top wall 32 and forming an extension thereof adjacent its inner side, and a side wall 35 in the plane of the side wall 31 and connected with the top wall 34. The wall 34 is provided with a slot or opening 36 and the wall 35 with aslot or opening 37. t its rear end, the inner wall 31 is provided with a flange 38 arranged substantially at right angles thereto.

The brackets 12 are adapted to be arranged at the tops of the side members 3 of the frame in a manner similar to the brackets 12. The top wall 32' engages the top of the side member which is arranged between the inner and outer walls 30 and 31. The flange 38 engages the rear wall of the head bearing member.

When the head bearing member 10 is arranged in the frame between the side members, the member 22 carried thereby engages the lugs 33 which pass through the openings therein, and to which it may be secured by the wedges 23 inserted in the openings 36, as will i be understood by reference to Figure l of the drawings. If desired, the wedges may be connected by flexible chains 24: with the bracket, the outer wall of which may be provided with a ring or eyelet 39 in which the chain may be secured.

In case it is desirable to use a very short shore in which the head, on which the forms are supported, is very near the top of the frame, or in which a T-head is mounted directly on the top of the frame, the wedges may be arranged in the horizontal openings 37 of the lug 33. In this arrangement, neither the head nor the forms supported thereon interfere with the removal or replacement of the wedges.

While the invention has been described with reference to certain details, it is not limited to the embodiments shown herein, and this application is intended to cover such changes or rearrangements as may come within the spirit of the invention or scope of the following claims.
