SHORE Filed June 1o, 1948 Patented Oct. 25, 1949 UNITED STATES PATENT OFFICE Application June 10, 1948, Serial No. 32,191 In Sweden April 16, 1948 2 Claims.

The invention relates to shores for use in building construction such as concrete molds for yarches and other work, an object of the invention being to provide improved means for this purpose comprising means for accomplishing both major and iinal micrometric adjustment thereof to Vary the length of the shore. Other objects and advantages will appear hereinafter or will be obvious.

The invention consists in the novel construction and combinations of parts as hereinafter set forth in the claims.

In the accompanying drawings,

Figure 1 is a side View of the invention as applied.

Figure 2 is a front view of the same, and

Figure 3 is a section on the line 3 3, Figure 1.

In these drawings, the numeral I designates the base member of the shore, and 2 the adjustable member thereof, these members being each of T- form in cross section with the heads thereof opposed to each other, ithe head of the base member being provided with gui-des 3 for and engaging the head of the adj ustabl-e member.

For the purpose of accomplishing major lengthwise adjustment of the member 2 with respect to the base member, a lever 4 is fulcrumed within a notch seat 5 of the flange of the base member, said lever being provided with a springurged pawl 6 engaging the ratchet teeth 'I of the fiange of the adjustable member.

For the purpose of accomplishing nal micrometric adjustment of the member 2 with respect to the lbase member, an eccentric device is mounted upon the upper end of the base member, said eccentric device being provided with manipulable means for accomplishing such adjustment described as follows:

An annular strap 8 is iixed to the upper end of the base member I, a cylindrical roller 9 being rotatably adjustable within said strap, said roller having an aperture I 0 which is eccentric with respect to the center of said roller, manipulable means for accomplishing the rotatable adjustment of said roller Within said strap comprising a horizontal arm I I Xedly secured to said roll-er within said aperture, said arm having a handle end portion I2 at right angles thereto. A bail I3 depends from and has its spaced ends pivotally engaging the opposite ends of said arm II at opposite sides of the shore. the lower end of said 2 bail engaging the ratchet teeth 'I of the ange of the adjustable member of the shore.

Thus rotative adjustment of said roll-er within said strap accomplishes eccentric adjustment of said horizontal arm I I with respect to said roller and micrometric adjustment of said bail and of the adjustable member of the shore, to vary the length of the shore. In order to fix this micrometric adjustment a clamp bolt I4 has threaded engagement with the ends of said strap, said bolt having a handle arm I5.

In order to center the shore with respect to the overlying work, two angle irons I6 located side by side have each a vertical flange I1, ithe two iianges rbeing spaced apart and engaging opposite sides of the support beam I8 of the mold for ith-e arch or other work, an underlying fplate I9 supporting both angle irons, loop clamp 20 engaging over the adjacent ends of both angle irons and said plate, said angle irons being laterally adjustable to adjust the flanges thereof for work of varying breadths, and said loop clamp having a set screw 2| to fix the adjustment.

I claim:

1. In a shore, a base member, `a, member vadjustable lengthwise with respect tothe base member to vary the length of the shore, and means mounted upon the base member and engaging the adjustable member to :accomplish major lengthwise adjustment thereof and nal micrometric lengthwise adjustment thereof comprising ,a cylindrical strap fast to the upper end of the base member, a cylindrical roller rotatable within said strap yand having an eccentric aperture, a manipulable dew'ce having a horizontal arm fixed to said roller 4within said aperture kand a bail depending from and one end of which is pivoted to said horizontal arm and the other end of which engages said adjustable member, said strap having manipulable means for closing the same upon said roller to fix the adjustment.

2. In a shore, a base member, |a member adjustable with respect to the :base member to vary the length of the shore, and means mounted upon the base member and engaging the adjustable member to accomplish major lengthwise adjustment thereof :and nal Ymicrometric adjustment thereof comprising an eccentric device mounted upon lthe Iupper end of the base member having manipulable means for accomplishing the eccentric adjustment thereof and for xing the -adjustment, the upper end of the adjustable member Ibeing provided with means for centering the shore with respect to the overlying work comprising two angle irons located side by side and hav- 5 10 Number 4 for work of Varying breadths, and said loop clamp having a set screw to x the adjustment.
