ADJUSTABLE MARKING GUIDE.

Application filed Au ust'ai, 1926. Serial No. 130,729.

My invention relates to adjustable marking guides, and the object of my improvement is to supply an adjustable device of this class which has means for indicating on opposite faces'of a block places for marking construction lines at the same relative Preparatory to the marking of construc tion lines upon opposite faces of a block of stone, such as a tombstone, and in which the design of the sculpturing includes lines to be engraven at the same level or height on said faces, it is desirable to provide a device for indicating the exact position of such a line on one face relative to a primary line to be drawn upon the other face, to insure exactitude in the work and to save time and labor cost.

My improved device is intended for this purpose, and has been found effective in practise.

My said device is composed of a pair of guide-bars or parallel straight-edges 1 and 2, whose upper edges are smooth and in the same horizontal level. The guide-bar 1 is the wider vertically and has at its four corners horizontal transverse holes to receive therethrough the terminations, threaded, of the vertically spaced parallel members a and 5 respectively of a pair of like looped rods. These rods are bent twice at equal distances from their middles providing a vertical con necting part 6 with the members t and 5 parallel. The narrower bar 2 has near each end short slots 7 which are transversely alined with the upper holes in the guide-bar 1. The upper members at of the loopedrods aforesaid are first passed loosely through these slots 7, the lower members 5 passing below the bar 2. The terminations of said members are then passed through the holes in the bar 1 after nuts 14 and 13 have been mounted on their threaded tern'iinations,

and then wing-nuts 8 and 9 above and below are mounted on the terminations to clamp the bar '1 between them and the nuts 14. and 13. i j

The device is then complete for service as above described, but I have shown in combination therewith means for supporting the device for vertical adjustment relative to. a block between thebars 1 and 2 as indicated by dotted lines in Fig. 1.

This means comprises a third bar 3 which is of the same length and placed below the bar 1 in vertical registration therewith. Bars 10 are used as pivoted connectors between the ends of the bars 1 and 3,- the upper ends of the bars 10 being pivoted on the terminations of the lower loop members 5, and the lower ends of the bars 10 being pivoted on the threaded terminations of bolts 12 whose stems are passed through holes in the ends of the bar 3 and secured by wing-nuts 11.

In practise, as shown in Fig. 1, the device is mounted about a block and the connectors 10 swung tolift the guide-bar 1 to the desired height along one face of the block, the wing-nuts then being tightened to support the bar 1 rigidly upon the bar 3 and the latter upon the supporting surface beneath. A line may then be drawn across the face of the block guided by the upper straightedge of the bar 1. The bar 2 having been moved along the loop members 4 and 5 to contact with the opposite face of the block, the upperedge of the bar 2 will be at the same level as the upper edge of the bar 1, so that a line may be drawn on the block along the .upper edge of the bar 2 at said level. In case of any slight difference in' thickness in the block between the bars 1 and 2, the

.slots 7 permit some relative movement to the bar 2 to swing slightly to thus contact evenly with the abutting face of the block. The lower bar 3 and its connectors 10 may be dispensed with if desired for some purposes, by separating the bars 10 from the lower terminations of the loop rods.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is: 1

1. A device of the character described, comprising a pair of opposed bars with like edges in the same plane, looped rods with parallel members in different planes, spaced apart and terminally secured to the end parts of one bar, the other bar being loosely slidably mounted upon said rods to be adjustably moved to and from the first-mentioned bar.

2. A device of the character described, comprising a pair of opposed bars With like longitudinal edges in the same plane, projections on the end parts of one bar, the other bar being slidably mounted upon said project-ions to move to and from the first-mentioned bar, a basal supporting member, adjustable connections between said basal member and the first-mentioned bar, and means for releasably securing said connections to said basal member and said bar to hold the bar in a desired position of adjustment relative to the basal member.

3. A device of the character described, comprising a pair of opposed bars with like edges in the same plane, looped rods with parallel members in different planes, spaced CARL H. MOLINE.
