MARKING-TOOL.

Application filed- July 26, 1920. Serial No. 398,876.

T 0 all whom it may concern.

Be it known that I, BENJAMIN Moss, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements inMarking-Tools, of which the following is a full, clear, and exact specification.

This invention relates to tools for marking material for plaitingor for produclng parallel marks forotherpurposes, and 1t 1s the object of the invention to provide a device of this kind which is simple in construction, easy to operate and capable of a wide range of adjustments.

A special object is to improve the construction of the marking pointsand adapt them for the use of detachable and adjustable tips or markers. Another object is to provide for adjusting the lazy-tongs carrying the marking points at an inclination to the horizontal so as to raiseall but one set of marking points out of contact with the surface tobe marked. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of thls specification, and then more speclfically defined in-the claims at the end of the de-.

scription.

In the accompanying .drawings,1where1n similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a plan view of a marking tool constructed substantially in accordance with this invention.'

Fig. 2 is a perspective view of a part of said tool.

Fig. 3 is a detailed view on a larger scale of one of the marking points, partly in section.

Fig. 1 is a plan view of the marker clamp on a still larger scale.

Fig. 5 is a detailed perspective view of one of the members'of the cam acting clampingjaws.

Fig. 6 is a side view of the guide member and carriage of the tool, showing the arrangement of the slots in the latter.

Fi 7 is a side view of the marking tool, showing theinclined adjustment of the lazytongs.

Specification of Letters Patent.

. and a horizontal portion 5.

Patented June 14, 1921.

Fig. 8 is a section a. the line VIII-VIII of'Fig. 1,

Flg. 9 1s a plan View of a modified form of the marking tool designed for marking concentric curved lines, and

Flg. 10 is a sectional view of the tip clamp of the Inarkingpoint'on a larger scale.

The device consists of a guide rail 1 which may be of any desired length and secured in place by screws 200 passed through ears 2. Aearnage 3 is adapted to slide along said rail 1 over which it fits. To said carriage there is adjustably secured a'bar preferably of angle form having a vertical portion 4 I Said portion 5 of the bar has a long slot 6 extending longitudinally thereof with which the lazytongs" of the marker hereinafter described is connected.

The carriage 3 has pairs of horizontal slots 10 entering from each end thereof, and a central vertical slot 11. Each of said slots 10 and 11 is of rabbet form'adap'ting them to receive the heads of the bolts 9' between said carriage and the guide rail 1. Said bolts extend through slots 7 arranged vertically in the portion t of the adjustable bar, and thumb nuts 8 arefitted on the outer ends of-said bolts for clamping said bar in adjusted position. It will be noted by reference particularly to F ig. 7 that the end bolts may be arranged in either of the end slots 10 according to the desired adjustment of. the bar, it being possible-with the arrangement of slots described to adjust said bar at an incline to the horizontal in either direction, as well as adjust it up and down in a horizontal position- The lazy-tongs comprises twosets of links 12 and 13 slidably connected at one end with the slot 6 by bolts 15having tightening nuts 16. A spacing washer 14 is placed between the slotted portion 5 of the bar and the end link 13 to supportit'on the same level with the uppersurface of the links 12. At the intersections of the lazy-tongs links they are swiveled together by mark ing devices comprising marking tip carriers having adjusting knobs 18 and shanks 19 which are screw threaded on their lower portions as at 20, see'Fig. 3. Said shanks pass loosely through the upper'links 13 but ing fingers come in contact with the end of the shank and cause said fingers to firmly grip thetip 24.. By loosening said cap the tip may be removed or adjusted to take up wear or for any other purpose desired.

The inclined adjustment of the bar and lazy-tongs shown in Fig. 7 is desirable when onlyone set of marking points is to be used.

When the bar is adjusted horizontallyall of the marking points may be utilized to make a series of parallel lines 25, Fig. 1, as the carriage 1S moved along the guide rall. As

shown in Fig. 9, the laay-tongs may be connected byconverging,links l'i to common point in the slot 6 and said lazy-tongs swung about said point as a center for describing concentric arcs 26. In this modification, the distance between=the concentric arcs ma'y be varied by extending or contracting the lazytongs, the same as in the preferred form the distance between the parallel lines 25 may be varied. It will be noted that the position of the markers 24 as shown in Fig. 7,. serves to bring the markers into an angle position or about as a pencil is held 1n thehand when writing, and that this position servesto per-' mit the markers to be more smoothly drawn over a surface to be marked than it the marking points were set vertically and that the possibilities of scratching or-tearing the surface to be marked are eliminated.

As shown best in Figs. 5 andlO, the con cave curve 27 oneach of the clamping fingers 22 will causethem to move bodily to-' ward the center when pressure is-applied to the ends of the cam portions 23 by screwing up on the cap 21, so that the vertical portions 22 of said clamping fingers will. grip the tip 24 uniformly throughout the length of said fingers. p

Having thus described my invention, what I claim as new and desire to secure by Letters Patent oi the United States is 1- 1. In a marking tool, the combination with a guide rail, of a carriage mounted to slide on said rail, lazy-'tongs. carried bysaid carriage and extensible in a direction trans.

verse to the guide rail, and marking devices on said lazy-tongs. j

2. In a marking tool, the combination with a guide rail, of a carriage mounted to slide on said rail, lazy-tongs carried bysaid carriage and adaptedto be adjusted at an inclination'thereto, means for retaining said lazy-tongs in adjustedposition, and marking points on said lazy-tongs.

3. In a marking tool, the combinationwith a guide raihota carriage mounted to slide on said rail, a bar adjustableon said carriage, and lazy-tongs carrying marking devices attached to said bar and extensible transversely to the guide rail.

4-. In amarking tool, the combination with a guide rail, of a carriage mounted to slide on said rail, a bar, lazy-tongs attached to. said bar to move'in the plane thereof, marking'deviceson saidlazy-tongs, the latter being extensible transversely to the guide rail, and means for permitting adjustment of said bar into dilferentpositions on said carnage.

10 .In a marking tool, the combination.

threade'dshank and adapted to clamp said jaws about said tip.

12. In a marking tool, combination with a bar, of a lazy-tongs, marking devices on said lazy tongs, and converging links connecting said lazy-tongs with said bar at a common pivotal point for permitting a series of concentric arcs to be described by swinging the lazy-tongs on its pivotal point of connection with the bar.

13. In a marking tool, a marking device having a threaded shank, a marking tip, clamping jaws for gripping said tip, and a cap adjustable on the end of the threaded shank and adapted to clamp said jaws about said tip, said jaws being angular in form with vertical gripping portions and inclined cam portions, there being curved eX- terior angles between said portions to cooperate with said cap for moving the jaws inward bodily to uniformly grip the tip throughout the length of the gripping portions of said jaws.

In testimony whereof I have signed myv name to this specification.
