[o all zul/tcm t may concern:
Be it known that I, JAMES GRAHAM GREEN, acitizen of the United States, residingat Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Glass-Cutting Table, of which the following is a specification.
This invention relates to an improved attachment for glaziers tables, and has for its object to provide a simple, inexpensive, and efficient device of this character capable of being readily attached to glasscutting tables or boards in general use and by means of which an unskilled person may conveniently and accurately cut either plane or plate glass in yany desired angular shape.
A further object of the invention is to provide means whereby the rule or straight-edge may be adjusted longitudinally of the table to cut pieces of glass of different widths and means for securely clampingsaid straight-edge in adjusted position.
A further object is to provide means for yieldably supporting the rule or straight-edge carrying-bar, whereby the same may be adj usted vertically to accommodate glass of different thicknesses.I
A still further object of the invention is to provide means for automatically elevating the rule or straight-edge after each cuttingoperation, so as to permit a new pane of glass to be placed in position on the board or table.
With these and other objects in View the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
ln the accompanying drawings, forming a part of this specification, Figure 1 is a top plan View of a glaziers board or table constructed in accordance with my invention. Fig. 2 is a side elevation of a portion of the same, showing the straight-edge in elevated position. Fig. 3 is a side elevation, partly in section, of the clamping members of the straight-edge. Fig. L is a vertical sectional view of one of the corner castings or brackets. Fig. 5 is a vertical sectional View taken on the laine 5 5 of Fig. t. Fig. 6 is a transverse sectional View taken on the line 6 6 of Fig. 5, and Fig. 7 is a detail sectional view of the locking-lever.
Similar numerals of reference indicate corresponding parts in all the figures ofthe drawings.
The cutting' board or table 5, which may be of the usual shape and formed of wood, metal, or other suitable material, is provided at the rear thereof with corner brackets or castings 6, in which is journaled a graduated guide bar or rod 7, the latter being preferably angular in cross-section and provided with terminal trunnions 8, which engage elongated slots or openings 9, bored, cast, or otherwise formed in the vertical extensions 10 of said brackets, as shown. The brackets 6 are provided with integral laterally-extending wings 11, which engage suitable recesses 12 in the face of the board, so as to present a smooth even surface to the glass to be cut and also to form an additional means for securing said brackets to the table or board. The bar 7 is preferably graduated to inches` and fractions thereof, as shown, and slidably mounted on said bar is a rule or straight-edge 13, also preferably graduated to inches and fractions thereof, so that the operator can determine at a glance the exact length and width of the glass to be cut without resorting to the use of auxiliary rules and similar measuring devices.
Carried by one end of the rule or straightedge is a clamping member preferablyformed in two sections 14C and 15, the section 14 being riveted or otherwise rigidly secured to the rule, as indicated at 16, while the section 15 is pivoted or hinged thereto, as shown at 18, whereby when the clamp is operated the angular sockets 19 of the clamp- sections 14 and 15 will vengage the bar 7 and eflectually retain the rule or straight-edge in adjusted position. The clamping member is operated to engage the bar 7 by means of a hand-lever 20, pivoted between a pair of spaced lugs 21 at a point adjacent the free end of the rule or straight-edge, and to which is fastened in any suitable manner one end of a fiexible rod or wire 22, the opposite end of which passes through suitable guiding loops or eyes 23 and.
is secured to a vertically-disposed arm or lug` 24, preferably formed integral with the n1ovable clampingsection and extending through an opening 25 in the adjacent fixed section, as shown. The flexible rod or wire also passes through a terminal opening in a lever 26, which latter is pivoted between a pair of vertical ears Q7 on the clamping-section 14 and IOO IIO
is provided with a curved lug or extension 28, adapted to bear against the clamping-section la when a longitudinal pull is exerted on the wire 22. It will thus be seen that when the hand-lever is moved to the position shown in Fig. 2 of the drawings the movable section will be elevated to thereby clamp the rod or bar 7, in which position it will be securely locked until said hand-lever is released.
As a means for automatically elevating the rule or straight-edge after each cutting operation suitable coil-springs 28 are provided, the normal tendency of which is to rotate the bar 7 in the direction of the arrow shown in Fig. 4, whereby when the clamping member is released and the hand removed from the free end of the straight-edge the latter will automatically assume the vertical position shown in Fig. 2 of the drawings, thereby permitting a new pane of glass to be properly positioned on the board or table. The springs 28' are seated in suitable openings 29, formed in the corner-brackets 6, and are secured, respectively, to the trunnions 8 of the bar 7and the interior walls of said openings, as shown. In order to adapt the device for cutting glass of different thicknesses, the bar 7 is also preferably yieldably supported in the slots 9, so as to afford the same a limited vertical movement, suitable springs 30, disposed in recesses 3l in the brackets and bearing upon the trunnions 8, serving to normally hold the bar depressed. It will thus be seen that the bar 7 is capable of both rotary and vertical movement and that the straight-edge being carried by said bar will also be elevated with the latter.
The corner-brackets 6 are preferably provided with detachable caps 32, so that the latter may be conveniently removed to facilitate the introduction and removal of the spring.
Secured to one end of the bar 7 is a depending bracket or stop 33, the free end of which is adapted to engage the rear edge of the table 5 to thereby limit the upward movement of the straight-edge when the latter is released, so that said straight-edge may be supported within easy reach of the operator.
From the foregoing description it is thought that the construction and operation of the device will be readily understood, and further description thereof is deemed unnecessary.
Having thus described the invention, what is claimed isl.
