SCALE Filed Feb. 14, 1929 amg Patented Dec. 27, 1932 PATENT `ortica TUNIS C. lNOLD, OFBOISE, IDAHO SCALE Application filed February 14, 1929, Serial No. 335,923.

This invention relates to a device for clamping independent scale members together to permit their use as an adjustable unit.

More specifically, the invention contemplates a body in the form of a guide member in which the scales are positioned and clamping means for clamping the scales individually, whereby separate adjustment of same may be attained.

@ther features of the present invention will be noted by reference to the accompanyinO drawing forming a part of this specifica- D u u tion and wherein like characters of reference r l n' s, .f 1 0 designate coiiesponding parts Vthi oughout the several views, in which: Fig. 1 is a side elevation; Fig. 2 is an end view;

Fig. 3 is al fragmentary perspective showing the parts in position for assembling; anld tig. 4 is a section on line 4 4 of Fig. 1.

Referring now to the drawing, reference numerals 1 and 2 indicate conventional scales which are usually constructed in one foot or i two foot lengths or decimals thereof. Each the member 3 may best be determined by the type and length of the scales in connection with which the assembly is to be utilized.

For clamping the scales in their adjusted positions screws 6 and 7 are provided. The screws G and 7 are threaded at one extremity and are cut away as at 8 for a portion of their length to form seats for the scales 1 and 2, and projections 8 for engaging the grooves 1 and 2. When in position the screws 6 and 7 extend through perforations 9 and 10 formed in the base of the U-shaped body. Thumb nuts 11 are utilized for locking the parts together. The perforations 9 and 10 formed in the U-shaped body are positioned at opposite sides and at opposite ends and at such points that a continuation of these perforations forms grooves 12 in the inner `faces of the wall members 4 and 5 of such a depth as to accommodate those portions of the screw Shanks remaining from forming the seat 8.

From the foregoing it will be seen that when it is desired to use two scales as a unit for the purpose of securing the increased length, the screws are first positioned within the grooves 12 and with the projections 8 turned inwardly towards the central passage between the walls 4 and 5. The scale members 1 and 2 are then positioned. with the grooves 1 and 2 facing outwardly and in register with the projections 8 permitting the scale members to be slid between the walls i and 5. Then the scale members are properly positioned with the projections engaging tae groove, they may then be adjusted relatively to one another as indicated in dotted lines in Fig. 1, and secured in this adjusted position by tightening of the thumb nut 11.

lli/That I claim as new and useful and de- F sire to secure by Letters Patent of the United States is:

1. A scale holder comprising a U-shaped body formed with staggered perforations at its intermediate portion and slots formed in C the opposite inner wall faces merging with said perforations, hook members extending through said perforations and seating in said slots. the outer faces of the hook members being fiush with the inner wall faces of said U-shaped member, scale members formed with longitudinally extending grooves in their outer faces and positioned between the arms of said U-shaped member, said hook members engaging the grooves in said scale members, and means for clamping said hook members in fixed position.

2. A scale holder comprising a U-shaped body formed with staggered perforations at its intermediate portion and slots in the opposite inner wall faces merging with said perforations, hook members extending through said perforations and having threaded outer extremities, scale members formed with longitudinally extending grooves in their outer faces carried by said U-shaped body member, said hook members engaging the grooves in said scale members, and'thumb nuts threaded onto the threaded extremities of the hook members.

3. An extensible scale comprising a U- shaped member formed With slots in its opposite inner Wall faces, scale members formed with longitudinally extending grooves in their outer faces and positioned between the arms of said U-shaped member, and locking means for said scale members normally positioned in the slots in the opposite inneI` Wall faces of said U-shaped member and having inwardly extending projections positioned in said longitudinally extending grooves of said scales.

' In testimony whereof I aliX my signature.
