PRINTERS lVllTER-TOOL..

SPECIFICATION forming part of Letters Patent No. 473,689, dated April 26, 1892.

Application filed May 12, 1890.

T0 all whom. it may concern.-

Be it known that I, VILLIAM H. F. BLOE- BAUM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and usefullmprovenients in Printers Miter-Tools; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make andnse the saine.

My invention relates to improvements in printers initer-tools.

The object of my invention is to produce a printers miter-tool which shall be simple of construction, convenient to use, durable, and not expensive.

The invention consists, essentially, ot' a work-table, a hinged rule-holder, adjustable means for supportingr and holding the ruleholder at any desired inclination, and suitable means for holding the rule in position for being operated upon.

Figure 1 is a left-side View, partly in section, along the line x, Fig. 2, and to Fig. 4. Fig. 2 is a plan view of the work-table. Fig. 3 is a right-side view of the device with a part of the work-table broken away. Fig. 4 is a plan of the rule-holder and devices connected therewith.

The same numbers and letters refer to the same parts in different iigures.

5 is the work-table, 31 30 its support, and 29 the base of the support, which may be made heavy enough to maintain the device in an upright and stationary position, or it may be bolted to a table or other support.

The Work-table 5 has an opening through its front end, into which the end of the ruleholder projects. Lugs 3 are formed on the end of the rule-holder, Figs. 1 and 4, and lugs 6 on the sides of the table 5,Figs. 1 and 2, and pins 2 hinge these lugs together. The axis of the pins 2, the edge of the end of the ruleholder 9, and the edge of the rule 7 all coincide in one line 1. This arrangement enables the rule-holder 9 to be rotated through any desired angle about the line 1, and thus enables any desired inclination to be given to the bevel on the end of the rule. The under side of the end of the rule-holder 9 is chamfered, as shown in Fig. 1, so that the holder 9 may have Serial No. 351,404. (No model.)

`the greatest possible downward swing and yet have its edge 1 close to the body of the table 5. The angle b 1 c indicates the amount of swing of the rule-holder, the plane through the axis 1 being considered. The holder 9 is held in any desired position by means of the sector-arm 10, which is rigidly attached at l1 to the side of the rule-holder 9 and has a central slot 14, through which a binding-screw or a pin 13 is placed for guiding and clamping the arm 10. The rule-holder 9 (shown in Figs. 1, 3, and-i) is rectangular in outline and has a central rectangular recess 2S in its upper side of the width and depth of a printers rule. A gage-bar 37, Fig. 4, is adjusted in aposition such that a rule placed in the recess 28 and resting against its upper end will come into proper position at the end 1. The gage 37 is held in place within the recess 2S by the binding thumb-screw 12, Figs. 1 and 4. The pins 13 and 25 also have thumb ends and screwthreads.

Metal pieces 17, Fig. 1, are pivoted at 19 to the sides of the rule-holder 9, and have a crosspart 2O 21 secured to their ends by screws 27, Fig. 4. A clamping-bar 8 is held in a rectangular slot between the parts 2O and 2l, as shown in Figs 1, 3, and 4, and is retained in place and guided. bythe pin 22 and aslot 28 in its center. The bar 8 may be clamped between the parts 20 and 21 by adjusting the screws 27, or the part 2l may be made of spring metal and thus hold the bar 8 in any desired position, while allowing it to be moved freely by the hand applied at the lower end. The bar S is designed to clamp a rule in place and hold it firmly while being operated upon. Such clamping action is obtained by means of the lever 24, and the eccentric 2G, having the pinbearing 25. The lever24E is rigidly connected to the piece 17 which is pivoted at 19, and hence when the eccentric is turned into the position shown in Fig. 3, the Lipper end ot' the bar 8 will press upon and hold the upper end of the rule iirxnly in place. The bottom surface of the recess 28 in the rule-holder 9 for the reception ot' the rule is in a plane which passes through the axis or edge 1, and the ends of the rule-holder at the sides of the recess are beveled on top, as shown in Fig. 4, at a, and the top surface of the table 5 is plain and horizontal.

IOO

The operation of mitering is performed by means of a file worked by hand and held and guided upon the top surface of the work-table 5, bearing both in front and back of the opening through its body into which the end of the rule projects, whereby a plain even surface at any desired angle can be formed on the end of the rule. The upper end of the clamping-bar'S is beveled on top, Figs. 1 and 4, so that it will not interfere with tiling While having its end bear close to the end of the rule. The sector is graduated, as indicated by the divisions 16, and an index is fastened on the side of the frame part 30, whereby any desired angle may be formed at the axis 1 accurately, and whereby adjustments for different angles may be readily made.

The work-table 5 may be connected to the top 29 30 in any suitable manner, as by bolts through the flange 31. The table 5 itself is to be made of case-hardened steel, and the top surface made perfectly plain and even, so that the file may be guided in a true plane, and not abrade or injure the guiding-surface of the table. The parts 9, 10, 17, 20, 21, 24, and 26, may be made of cast or malleableiron. The parts 8 and 37 may be made of brass,

I claiml. In a miter-tool, the combination of a main table having an even flat top surface and an opening in one end and two pivotal points, one at each side of the opening, a ruleholder having one end pivoted at its upper end to the pivotal point ofthe table and so as to turn about an axis extending across the opening in the table and coincident with the upper surface of the table, substantially as set forth.
