INVENTOR RNEY6 Patented Feb. 21, 1939 UNITED STATES PATENT OFFICE SHORE Application July 20,

2 Claims.

j My inventionrelates to adjustable shores, and especially to the general type of shore illustrated in United States Letters Patent to Roos No. 1,368,353, granted February 15, 1921. It is my object, to increase the range of adjustability of such a shore and to do so by a simple and inexpensive means.

A shore of the type with which my invention is concerned comprises two telescoping parts one of which is composed of two longitudinally extending transversely spaced parallel members, conveniently pieces of lumber, betweenwhich the other shore-part is telescopically received. In embodying my invention in such a shore I provide at the end of the former shore-part a pair of opposed channel members which are secured to and extend in spaced relation between the two members of such shore-part. In addition, I provide a generally U-shaped stirrup which extends inwardly from the ends of the shore between the two longitudinally extending members thereof and between the two channel-members. The end of each leg of this U-shaped stirrup is bent outwardly to rest on the upper end of the associated longitudinally extending shore-member and then downwardly to provide a flange secured against the outer face of such member. This stirrup is adapted to receive and support one end of a shoreextension which is conveniently formed of a piece of lumber substantially square in cross-section and which can be of any desired length.

The accompanying drawing illustrates my invention: Fig. 1 is a side elevation of a complete shore to which my invention has been applied,

showing the shore as it is used when no extension is desired; Figs. 2 and 3 are elevations of the upper end of the shore with a shore-extension in place; and Fig. 4 is an isometric view illustrating the upper end of the shore with the extension removed.

The shore shown in the drawing comprises two telescoping parts III and II, the part III being shown as composed of two longitudinally extending side members I2 and I3 between which the part II, conveniently in the form of a length of pipe, is received. As shown in the drawing, the part It is the upper part of the shore, while the part I I extends downwardly therefrom to rest on a supporting surface I I. For convenience in description, it will be assumed that this position of the shore is always maintained; but it will be obvious that the shore may be inverted or may occupy a position other than vertical.

The upper end of the pipe II is provided with a guide I5 which engages the members I2 and I3 1936, Serial No. 91,512 (01. 24s--s54) to hold the upper end of relation thereto. part It, there are mounted on the members I2 and I 3 dogs It and I l which engage the pipe II in the manner more particularly set forth and described in the aforesaid Patent No. 1,368,353. Means (not shown), conveniently of the general type shown in that patent, is provided for extending the shore, and a clamp I8, acting between the members I2 and I3, may be employed to aid the dogs I6 and I I in holding the shore in extended condition.

The particular form of shore illustrated and described is cited merely as an example of one form of shore in which my invention may be embodied. In embodying my invention in the shore shown, I provide at the upper end of the part III a pair of opposed channel members 20 and 2| the flanges of which overlie the outer surfaces of the members I2 and I3 and the webs of which extend between such members to maintain them in proper spaced relation. Between the upper ends of the members I2 and I3 there is disposed a stirrup 22 of a general U-shape and having the upper ends of its legs bent outwardly to rest on the upper ends of the members I2 and I3, as is clear from the drawing. Conveniently, the extreme ends of the stirrup 22 are bent downwardly to overlie the flanges of the channels 20 and 2|. Bolts or rivets 23, passing through the bent-over end of each leg of the stirrup 22 and also passing through the flanges of the channels 20 and 2|, secure the channel members and the stirrup to the side members I2 and I3 of the shore.

The shore extension 25 shown in Figs. 2 and 3 has a cross-section such as to be received between the parallel legs of the stirrup 22 and the webs of the channels 20 and 2| and may have any desired length. The lower end of the shoreextension rests on the bottom of the stirrup 22, as is clearly shown in Fig. 2, to transmit to the shore-part I any thrust sustained by the extension 25. Conveniently, there are provisions for detachably securing the shore-extension in place. As indicated in the drawing, the webs of the channels 20 and 2| are provided with alined openings 26 adapted to receive bolts 21 which pass through holes suitably provided in the shore-extension. In case it might be desired to employ a shore-extension which was not drilled for the passage of the bolts 21, the webs of the channels 20 and 2| may be provided with additional, and smaller, holes 28 through which nails may be driven into the shore-extension. By using double-headed nails for this purpose, they the pipe I in proper Near the lower end of the shorecan easily be withdrawn when it is desired to remove the extension.

The shore may be used with or without an extension; but when no extension is used, I prefer to provide for the shore-part III a head of the type illustrated in Fig. 1. This head may comprise a short shank 30, having a cross-section permitting it to bereceived between the legs of the stirrup 22, and a cross-piece 3| secured in any desired manner to the upper end of the shank and adapted to rest upon the upper ends" of the stirrup 22. To hold this head in place, straps 32, conveniently of sheet-metal, pass transversely across the cross-piece 31 and have their ends bent downwardly to overlie the web of the channels 20 and 2| to which they may be secured by nails 33 passing through the straps and the holes 28 into the shank 30.

I claim as my invention:

1. In an adjustable shore having two telescopingparts. one of which comprises-two spaced longitudinally extending members, a pair of opposed channels having webs extending between said members on opposite sides thereof and flanges engaging the outer surfaces of said. members, a u-shaped stirrup disposed in the space defined by said members and the webs of said channels and having the ends of its parallel legs bent to extend outwardly over the ends of said members and along the outer surfaces of the channelflanges, fastening means extending through each such bent end, the adjacent channel-flanges, and the adjacent shore member to hold the stirrup in place, a shore-extension seated in said stirrup, the web of at least one of said channels being provided with one or more openings, and means extending through said openings and into said extension for holding it in place.

2. In an adjustable shore having two telescoping parts one of which comprises two spaced longitudinally extending members, a pair of opposed channels having webs extending between said members on opposite sides thereof and flanges engaging the.- outer: surface of said members, a U-shaped stirrup disposed in the space defined bysaidmembers and the webs of said channels, means for-securing said stirrup in place, a shoreextensionseated in said stirrup, the webs. of said channels being provided with openings, and, means extending through said openings and into said extension for holding it'in place.
