SHORE ATTACHNKENT.

Application filed July 13, 1926.

My invention relates to an attachment for adjustable shores, and is designed more particularly to afford an extension member that is quickly-attachable to a shore head and to take care of requirements where a head of longer than usual dimensions is necessary, or where the shore is employed for supporting exterior beams.

A further object of the invention is to provide an extension member of low manufacturing cost that can be attached in a few moments to the usual shore head.

Another purpose of the invention is to afford a metallic extension member that can be easily transported and is always in readiness for quick assembly on a shore head, when it is desirable to increase the length of the latter for either interior or exterior beam supporting.

To these and other ends, the invention consists in the construction that will appear clearly from the following description, when read in conjunction wit-h the accompanying drawing, the novel features being pointed out in the claims following the specification.

In the drawing:

Figure 1 is a side elevation illustrating the invention applied to the head of an adjustable shore, for use in supporting an exterior beam;

Figure 2 is a side view, with a portion of the shore broken away, and showingthe extension member applied to ashore head for use in supporting an interior beam;

Figure 3 is a side view showing the exten sion member folded for transportation;

Figure 1 is a perspective view of the extension member inverted, with the brace removed;

Figure 5 is a detail sectional view on line 55 of Figure 1, and

Figure 6 is a side elevation of the shore, showing the cleat which holds the free end of the brace in operative position.

Referring more particularly to the drawing, in which like reference numerals refer to the same parts throughout the several views, I have illustrated the invention in connection w'tn an adjustable shore of conventional type, including a supporting post 1 and a frame adjustable vertically thereon and consisting of side members 2 and 3, and a head 4 permanently attached to the side members.

In the majority of shoring operations, the head at as shown is of suflicient length to func 7 ti n properly, but in many operations a longer Serial No. 122,109;

head is required. This is true with respect to supporting both inside and outside beams, in the latter of which bracing means is neces-. sary for the outer end of the head. The usual way of taking care of such conditions is to cut a suitable wooden beam and nail it to the conventional shore head. Where a brace is required, this must also be cut and nailed in place. i

My invention does away with this tedious and expensive process by providing an extension member that can be quickly slipped on to the head of a conventional shore togive the required additional length of head. either distributed equally on both sides of the center of the shore or affording an increased length to one side, as for exterior beam supporting. The extension member is preferably constructed of malleable iron or pressed steel, and comprises a top wall 5, a side wall 6, and transverse walls 7 terminating in bottom supporting flanges 8 extending on opposite sides thereof.

This arrangement affords two pockets, one centrally of the extension member and the other at one end thereof, which conform to and embracethe ends and top of the head t as shown in Figures 1 and 2. The shore head is fitted to the extension member by relative lateral sliding movement of the parts, so that the head 4. is read ly fitted into one or the other pockets of the extension member. The latter may be attached by nails or screws to a wooden beam 9 upon which the concrete forms rest.

Where the structure is used for supporting an exterior beam, as in Figure 1, it is necessary to brace the end of'the'extension head, and to accomplish this I provide a brace 11 which is pivoted at 12 to ears 18 forming part of a support that is suitably attached to the extension member. The free end of the brace 11 carries an angular portion 14 which is engageable' behind the cleat 15. the. latter being fixedly attached to the side member 3 of the shore.

The brace 11 and its angular portion 14 can be engaged with the cleat 15 by a lateral sliding movement at the same time that the extension member is fitted on to the head 4:, or suflicient play can be allowed between the brace 11 and its pivotal support to permit of swinging the brace behind the cleat 15, after which it may be held in place by a nail 16 passing through openings in the respective members and engaging the side member 3 of the shore. l/Vhen the brace is not in use, as

where the extension member is fitted to extend equal distances on both sides of the shore, as in Figure 2, the brace can be left to swing idly or may be nailed against the side member of the shore to hold it out of the way if preferred. When the structure is to be transport-ed, the brace 11 is folded against the extension member as shown in Figure 3.

lVhile I have described the invention with reference more or less to a particular embodiment, it is not confined to the details of con struction herein set forth, and this application is intended to cover other modifications and departures such as may come within the intent of the improvements or the scope of the following claims.

I claim:

1. The combination with a shore having a head extending transversely of the shore with each end projecting a substantial distance past the side of the shore, of a quickly attachable extension member having means for embracing the top and ends of the shore head.

2. The combination with a shore having a head extending transversely of the shore with each end projecting a substantial distance past the side of the shore, of a quickly attachable extension member provided with a pocket open at one side for receiving said head and engageable therewith by a relative lateral movement.

3. The combination with a shore head, of an extension member comprising a top wall, a side wall, and transverse walls terminating in horizontal bottom flanges, affording a pocket for engagement with said head.

4:. The combination with a shore head, of

an extension member comprising a top wall,

sion member, the free end of the brace being attachable to a side of a shore.

5. The combination with a shore having a head extending transversely of the shore with each end projecting. a substantial distance past the side of the shore, of a quickly attachable extension member provided with means for embracing said ends and engageable therewith by a relative lateral movement of the head and extension member.v

6. The combination with ashore having a head extending transversely of the shore with each end projecting a substantial distance past the side of the shore, of a quickly attachable extension member provided with means for embracing said ends and engage able therewith by a relative lateral movement of the head and extension member, and a brace connected near one'end of the extension member, the other end of the brace being attachable to the adjacent side of the shore.

7. The combination with a shore having a head extending transversely of the shore with each end projecting a substantial distance past the side of the shore, a quickly attachable extension member having means for embracing the top and ends of the shore head, and a brace connected near one end of the extension member, the other end of the brace being at tacha-ble to the adjacent side of the shore.

8. The combination with a shore having a head extending transversely of the shore with each end projecting a substantial distance past the side of the shore, a quickly attachable extension member having means for embracing the top and ends of the shore head and engageable therewith by a relative lateral movement, and a brace connected near one end of the extension member, the other end of the brace being attachable to the adjacent side of the shore.

In witness whereof, I have hereunto signed my name.

HENRY W. RODS.
