JOINTED SQUARE.
SPECIFICATION forming part of Letters Patent No. 739,054, dated September 15, 1903.
Application filed February 24, 1903. Serial No. 144,801: (No models To all whom it may concern.-
Be it known that I, HARVEY G. BOGERT,
' Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Jointed Carpenters Squares, of which the following is a specification.
This invention relates to squares, preferably constructed of metal, which are so constructed that one section may be detached from the other for the purpose of packing the square within aitool-box or elsewhere, and the invention more especially relates to the means by which the'se'ctions are detachably held together.
The invention consists in the features of construction and combinations of parts hereinafter described and claimed.
In the drawings, Figure 1 is a plan View of the entire square; Fig.2, a view of the crossbar of the square; Fig. 3, an end view of the long or main bar of the square with a'portion thereof removed; Fig. 4:, a corner view of the square; Fig. 5, a sectional view takentransversely of the cross-bar and longitudinally of the main or long bar; Fig. 6, a top view of the expansible block or wedge; Fig. 7, a bottom view of the wedge in contracted relation, and Fig. 8 a similar view of the wedge in expanded relation.
The square of this invention consists of a main bar A, preferably of regulation length, and a cross-bar B at right angles to the main bar, and in the end of the main bar is a slot or recess 0, cut in the body of the bar, and the face D of the bar at this point is cut down in to leave a shoulder 01, against which a plate E contacts, so that the outer face of the plate E will lie flush with the outer face of the bar,
leaving a rectangular recess 0 within the end.
of the bar, and the plate E is preferably held in place by means of rivets e passing through holes e in the end of the bar. The cross-bar is provided with a tongue F of dimensions to fit snugly within the recess in the end of the main bar, and the cross-bar is further provided with holes f, two in number, one on each side'of the tongue, and these holes are in alinement with pins or studs f in the end of the main bar, which are adapted to extend into the holes when the two sections of the square are, brought together by slipping the tongue of the one member into the recess of the other member. Within the tongue at a suitable distance from the bar is a hole G, preferably rectangular in shape. In the walls of the recess are similar holes H and H at a distance from the end of the main bar slightly greater than the distance of the hole G from the cross-bar, which arrangement is such that when thetongue is slipped vinto the recess the edge of the hole in the tongue will lie within the edges of the outer walls, forming, in effect, a groove h for a purpose to be hereinafter explained, and in like manner the opposite edges'of the hole in the tongue will project beyond the edges of the holes in the walls of the recess, forming, in effect, a ridge of like dimensions with the oppositely-disposed groove or recessh In order to maintain the engagement of the two bars and the tongue within the recess and the pins within their respective holes, an expansible block I is provided,which block is preferably constructed of spring-steel, although other metals might be used under some circumstances, and said block is provided on one of its edges with a ridge 1;, adapted to enter the recess h, and is provided on its opposite edge with a flange i, adapted to abut against the ridge h when the flange has been forced into place. The block is provided in one of its faces with a transverselyextending slot 1 of a depth sufficient to allow the block to be readily expanded, and in the center of said groove and of a greater diameter than the groove is a screw-threaded hole J, extending down into the body of the expansible block, and within said hole is a-tapered screw J, having its end of a diameter to enter the hole when the block is in compressed relation and having its head end of a diameter to expand the block as the screw formed by the holes holding the two sections of the square in true relation to one another. Whenever, however, it becomes necessary to take the two sections apart for the purpose of packing or otherwise, the same may be readily accomplished by unscrewing the tapered screw and allowing the expansible block to contract, so that the ridge thereon will spring out of contact with the groove formed by the hole in the tongue, allowing the block to be removed and the tongue withdrawn from the recess without difficulty. The tongue is preferably made of a length equal to the width of the main bar or section of the square, so that when the two sections are placed side by side the tongue will not project, thereby facilitating packing of the sections without impairing the efficiency of the tongue.
It is preferred to make the entire square of steel,as is customary with carpenters squares; but I do not limit myself to the use of such metal, as other metals or materials might be employed. The expansion of the block tends to draw the tongue down into the recess and force the pins up into their respective holes, therebyinsuring a firm and solid joint between the two sections.
WVhat I regard as new, and desire to secure by Letters Patent, is
l. Ina jointed square, the combination of two sections one of the sections being provided with a recess and the other section provided with a tongue adapted to slip thereinto, the tongue being provided with a hole and the walls of the recess being provided with holes slightly out of alinement with the hole in the tongue leaving a groove between the tongue and the outer walls of the recess, and an expausible block or wedge adapted to en- .ter the holes and be expanded therein to enter the groove and hold the tongue within the recess and compress the sections of the square together in angular relation to one another, substantially as described.
2. In a jointed square, the combination of two sections at right-angle relation to one another, one of the sect-ions being provided with a tongue and the other section provided with a recess the tongue being provided with a hole and the walls of the recess being provided with holes slightly out of alinement with the hole in the tongue forming a groove when the tongue is slipped into the recess, an expansible block or wedge provided with a transversely-extending slot or cut and a screw adapted to enter the cut and expand the wedge forcing the two sections of the wedge together,
substantially as described.
3. In a jointed square, the combination of a main section provided in its end with a recess, a cross-section provided on one edge with a tongue at right angles to the cross-section and adapted to enter the recess in the main section, the tongue being provided with a rectangular hole and the walls of the recess being provided with rectangular holes slightly out of alinement with the hole in the tongue, forming when the tongue lies within the recess, a groove or depression, an expansible block or wedge provided on one edge with a ridge adapted to enter the aforesaid groove and provided with a transversely-extending slot or out having a screw-threaded hole and a tapered screw adapted to enter the screwthreaded hole and to expand the wedge causing the ridge to enter the groove and lock the tongue within the recess, and pins or studs in one of the sections adapted to enter holes in the other section, substantially as described.
