WILLIAM H. EGGLESTON, OF GRANDVILLE, MICHIGAN, ASSIGNOR OF ONE-HALF T0 DAVID RITZEMA, OF GRAND RAPIDS, MICHIGAN.
EXTENSION Anew-SQUARE.
Specification of Letters Patent. Patented J an. 27, 1920.
Application filed January 13, 1919. Serial No. 270,939.
To all whom it may concern:
Be it known that I, WILLIAM H. EGGLES- ToN, a citizen of the United States of America, residing at Grandville, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Extension Angle-Squares; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.
- This invention relates to a tool or implement for use by carpenters or other mechanics and which I have termed an extension angle square, being particularly useful in transferring measurements and angles of position with respect to openings to be fitted with closures so that a proper outline of a closure for an opening may be obtained very readily with the tool. It is an object and purpose of the invention to produce a tool, and make the same in a simple and economical manner, which will serve the function above outlined as well as many others as will more fully appear from the following description taken in connection with the accompanying drawing, showing a preferred and practically operative form of the invention.
In the drawing,
Figure 1 is an elevation of the complete implement.
Fig. 2 is an enlarged under plan view of the construction shown in Fig. 1, the right hand end thereof only being shown, and a part of the same being in section.
Fig. 3 is a fragmentary longitudinal section through certain of the telescoping members of the device and showing the stop means for limiting the extension of the implement.
Fig. 4 is a transverse 4-4 of Fig. -1.
Fig. 5 is a fragmentary elevation of one end of the telescoping extension portion of the implement, and
Fig. 6 is a longitudinal section through the right hand end of the implementshown in Fig. 1.
Like reference characters refer to like parts in the different views of the drawing.
In construction three telescoping members 1, 2 and 3 are used, members 1 and 2 being of tubular form and member 3 being section on the line a rod circular in cross-section, preferably. Each. of the tubes 2 and 3 is slotted as indicated at 4 and 4, respectively in one side and at oneend, in which end a sleeve 5 of sheet metal, also correspondingly slotted in one side is secured so that the rod 3 passes through such sleeve to enter tube 2, and tube 2 at its other end passes through the sleeve in entering the end of tube 1. A plug 6 having a head 7 is threaded into the end of tube 2 within tube 1, the head 7 being of a size to move freely along the inside of tube 1 but incapable of passing the sleeve 5. Similarly the inner end of the rod 1 may be bored and tapped to receive a similar plug 6 having a head 7 to prevent disengagement of said rod and the tube 2 into which it inserted. This construction permits an easy and ready extension of the telescoping members without any binding and without liability of the telescoping parts separating from each other. Around the slotted ends of tubes 1 and 2 a band 8 of metal. is secured terminating at its ends in ears 9 which come one at each side of the slot 4 and through which a binding screw 10 is passed, one end having an operating finger member 11 so that the band may be tightened or loosened at will, permitting extension of the telescoping members and fixing the same against movement at any desired position.
At the outer end of the tube 1 a member 12 is located, being formed with a collar 13 to go against the end of the tube and with a threaded plug 14 to thread into the end thereof and permanently Solder mavbe used to effect permanency if desired. The member 12 includes a substantially circular portion 15 having a squared opening 16 through it as shown in Fig. 5. The outer end of the rod 3 also carries a similar member 12, the only difference being that the plug 14 is absent and the end of the rod 3 is threaded into a threaded opening made in the end of said member 12.
A bar 17 of flat relatively thin metal and having a straight outer edge 18 is positioned,- under each of the circular portions 15 of the members 12 and a bolt 19 inserted through the bars and said openings 16. The head of the bolt 19 is of frusto-conical form as indicated at 20, and the opening through a bar 17 is countersunk so that the bar may secure it in place.
turn freely on the head. Adjacent the head when the nut is loosened a porton of the bolt 19 is square in cross-section, said squared portion 21 entering the squared opening 16, thus holding the bolt against movement with respect to the members 12. A binding nut 22 threads on to eachbolt 19 and is equipped with a radially extending arm for operation of the nut, the operation of the nut being such that when it is turned to position such as to tightly bind the parts togetherand hold the bars 17 against movement the arms 23 come within the outer straight edges of the bars 17 and, preferably, directly over the members 12. In practice, it is desirable to head over the ends of the bolts 19 making heads 24 which preclude template detachment of the bars 17 but permit a slight movement of the nuts so as to release the bars for turning movement.
A tool or implement of the character de scribed is particularly useful in many cases where carpenters desire to fit closures into openings, it being possible to set the implement in the opening, adjusting it so that the straight edges 18 of the bars 17 he snugly against the sides of the opening, then tightening the various nuts and binding screws and 10 to hold the implement in any position to which it may be adjusted, after which it may be transferred to a board or the like and lines drawn along the edges of the bars 17, thus outlining the closure to fit in the opening. The bars 17 may taken many different angles with respect to each other and the length of the telescoping members, and the telescoping members may be adjusted to an indefinite number of positions this making the implement of practicall'y universal usefulness betweenthe limits of the shortest and longest lengths of the telescoping members. There are many places where such a device is useful, particularly in fitting in any partition or the like where the boards have to be cut at an angle which otherwise may be hard to determine. The positioning of the operating arms 23 always within the line of the outer straight edges 18 of the bars 17 insures 17 insures against any interference of the arms with the side of an oeniiig in which the implement is placed.
he structure is simple in construction, readily manufactured, the telescoping action of the tubes 1 and 2 and rod 3 is smooth and when not in use, the implement may be made to occupy very small space, bars 17 being placed in alinement with the telescoping'mernbers, so that the same may be placed in narrow ease and carried conveniently in the usual tool chest ofcarpenters and other mechanics that use. it.
I claim:
1. In combination, an extension member comprising parts adjustable lengthwise of each other, means to secure the parts in fixed relation to each other in any position to which they may be adjusted, a member connected to each end of the extension member and having a squared opening therethrough, a bar of flat metal located under the end of each of said last mentioned members, a bolt extending through the bar and the said opening in each of said members, said bar being pivotally mounted on the bolt, and said bolt having a squared portion entering the said squared opening, and a binding nut threaded on to the bolt and adapted to bear against the upper side of each of the members at the ends of the ex' tension member.
