`SCALE AND GAGE FOR PFiINTER'S USE.

'SPECIFICATION forming part of Letters Patent N o. 691,715, dated January 21, 1902.

Application filed June 4, 1901. Serial No. 63,091. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOSEPH L. DODD, a citizen of the United States, and a resident of Camden, Camden county, New Jersey, have invented certain Improvementsin Scales and Gages for Printers Use, of which the following is a specication.

My invention relates to certain improvements in scales and gages for printers use, applicable more particularly for use in connection with lead-cutters and the composingsticks in which type is set.

My invention is fullyillustrated in the accompanying drawings, in which- Figure 1 is a perspective view illustrating my invention as applied to a lead-cutter. Fig. 2 is a plan view showing the application of my invention to a composing-stick. Fig. 3 is an enlarged view ofa portion of myinvention, illustratinga detail thereof; and Figs. 4 and 5 are views of certain modifications of parts of the mechanism forming the subjectof my invention.

In printing offices of the present day the scale of measurement is that which is known as the point system, in `which twelve points equal one em pica, and ysix ems pica equal one inch, and the scale and gage which I have devised is adapted particularly for effecting measurements in the cuttingof lead and the gaging of the width of lines of the type to be set on this scale.

The gage which I have constructed is adapted to be adjusted in one place in accordance with the pica measurements'and in another place in accordance with the point measurements, and by the combination of these two scales I am enabled to effect measurements in points and pica of any required size within the limit of work required.

In the drawings herewith, 1 represents a suitable frame forming the bed of a lead-cutter, which frame is supported by means of a bracket 2, having the lower forked portion 3, adapted to engage the front rail 4 of a composing frame, being held thereto by the Pivotally mounted at 5 on the end of this bed-frame is a knife-handle 6, carrying the movable knife 7, which coacts with the fixed knife 8, carried by the bedplate 1. The handle 6 is adapted to the guide 9,'and a spring 10 is employed for keeping the knife normally in the raised position.

Carried by the side of the bed-frame 1 is a triangularly-toothed rack,- the teeth of which" are shown at 11, and adapted to engage these teeth is a pawl 12, pivoted at'13 to a slidepiece 14, carried by the raised edge 15 of the bed-frame 1 and movable along said frame.

This slide controls the position of the knee-1 piece 16, ,which serves as the gaging-stop against which the leads to be out are held.

hold them in positive engagement. The slide' is so made as to move along the bed-frame 1, havingportions contactingtherewithoneither side of the rack, and connecting these portions is .the yoke-piece 21, to which both the pawl12 and catch 17 are pivoted. The teeth 11 of the rack are formed with two beveled faces, and the pawl is beveled to engage such faces. While I do not wishto limitmyself to this form of tooth, I prefer it, for the reason that if the points of the teeth wear as well as the point of the pawl the beveled faces of the latter engaging the beveled faces of the teeth will insure the centering of the pawl and the correct adjustment of the slide 14.

The parts just described provide for the adj ustment of the knee-piece 16 in pica measurements, such measurements being the coarse adjustment of the gage. fine adjustment in points, I arrange the kneepiece 16 so that it is movable with, respect tol T0 provide for the' 9o the slide 14, each part having coacting por- This is more clearly ICU turning said catch 25 down into place, as shown in Fig. l.

In Fig. 2 I have shown the mechanism just described as applied to printers composingsticks 1. All the rest of the parts are similar to the structure shown in Fig. 1 and are lettered accordingly.

Instead of using the pawl and catch, as illustrated in Figs. l and 2, for holding the slide and knee-piece to the pica-rack I may employ, as shown in Fig. 4, a spring 26, carried by the yoke-piece 21 and adapted to engage a pawl 27, pivoted to said yoke-piece, such spring serving to hold said pawl in engagement with the rack. When it is desired to move the knee-piece, the frame 14 will be slid along without touching the spring 26.

In Fig. 4 I have also illustrated another form of rack, in which the teeth 1la are provided with an abrupt face on one side of the same. By the use of such teeth as these all danger of accidental movement of the kneepiece by pressure on the lead to be cut will be obviated. In connection with this form of teeth I have shown the spring-controlled pawl 27, as above described, and as such pawl may only ride over the teeth in one direction I provide the pawl with a hooked end 28, so that it may be readily lifted to permit adjustmentin theotherdirection. Thepointscale may also be provided with teeth of this character, and in lieu of the catch 25, as shown in Fig. l, I may employ the spring 29, as shown in Fig. 5, such spring engaging the depending arm 30 of the frame 14 and the extension 16a of the knee-piece 16.

When desired to adjust the knee-piece along the point-scale, it is only necessary to move such knee-piece against the spring 29, releasing the coacting racks 22 and 23 and permitting the movement o"f the said knee-piece 16 to the desired position.

In order to prevent any rise of the kneepiece during any operation of my improved scale and gage, whether as a lead-cutter or composing-stick, I provide the slide with a projecting portion 3l, extending over the knee-piece and partially covering the same in all of its adjusted positions.

As clearly pointed out in the specification and clearly shown in the drawings, the structure forming the subject of my invention is applicable with equal advantage to both a leadcutter and composing-stick, and unless otherwise specifically restricted the claims are to be construed as covering a lead-cutter and printers composing-stick.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. rlhe combination of a frame or bed for printers use, a rack carried thereby, an adjustable stop carried by said frame, securing devices carried with said stop and adapted to engage the rack,and means for adjusting said stop independently of the rack.

2. The combination of the frame or bed for printers use, a rack carried by the same, a movable slide-frame carried by said bed, engaging means carried by said frame whereby it may be held to the bed, a stop carried by the frame and held therewith, and means for y adjusting said stop with respect to the movable frame.

3. The combination of the frame or bed for printers use, a rack carried thereby, a movable frame carried by the bed, a pawl carried by said frame and adapted to engage the rack and hold said movable frame in a predetermined position, an adjustable stop or knee-piece carried by said movable frame, means for adjusting said stop with respect to the movable frame, and means for locking the movable frame and the movable stop in their adjusted positions, substantially as described.

4. The combination in a lead-cutter, having the bed-frame carrying a fixed knife, and a pivoted knife adapted to coact therewith, of an adjustable stop for determining the length of the lead to be cut, a movable slide-frame carrying said adjustable stop, a rack carried by the bed-frame and serving to control the position of the movable frame, and a liner rack arranged between said movable frame and the adjustable stop whereby said stop may be adjusted with respect to the movable frame.

5. The combination ina lead-cutter, of the bed-frame carrying a fixed knife and a pivoted knife adapted to coact therewith, of an adjustable stop for determining the length of the lead to be cut, a movable frame carried by the bed-frame and serving also to move the adjustable stop, a rack carried by the bedframe, a pawl carried by the movable frame and adapted to said rack whereby the position of the movable frame may be controlled, and a finer rack arranged between the movable frame and the adjustable stop whereby said adjustable stop is permitted movement with respect to the movable frame, and means carried by the latter for locking said stop in its adjusted position, substantially as described.

6. Thecombination of the frame or bed for printers use, a rack carried by the same, a slide-piece adapted to the frame and carrying a gaging member, a pawl pivoted to the slidepiece and adapted to engage the rack, and a pivoted catch also carried by the slide-piece and adapted to lock the pawl in place.
