GAGE FOR SCRIBING WORK.

Specification of Letters Patent.

Patented Oct. 15, 1912.

Application filed February 6, 1912. Serial No. 675,864.

To all whom it may concern.'

Be it known that I, Gnonen A. Moss, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Gages for Seribing lVork, of which the following is a specification.

The hereinafter described invention relates to an improved tool for the use of carpenters in obtaining an accurate outline measurement of the work to which a piece of wood work is to be united, as, for instance, in connection with the fitting of a partition to the existing ornamental mill-work within a building, whereby the piece to be fitted may be cut to make a perfect lit or joint with the surface of the exist-ing woodwork to which it is to be joined; the object of the invent-ion being the production of a simple, inexpensive, accurate and positive gage for use iny obtaining an accurate reproduction or outline of the piece or molding to which the new work is to be joined or fitted, oy means of which the taking of repeated measurements thereof and the cutting of the board or piece to be fitted may be avoided.

To comprehend the invention reference should be had to the accoinpanyii'lg drawings, Wherein- Figure l is a plan view of the improved gage with its cover plate and the presser plate partly broken away. Fig. 2 is a longitudinal sectional View taken on line acl- Fig. l of the drawings. Fig. 3 is a detail view illustrating the improved gage as applied for securing a measurement of a. piece of molding. Fig. L is an enlarged des tail View of one of the gage pins removed from the holder. Fig. 5 is a broken view illustrating the cover plate detached from the holder,

In the dra-wings, the numeral l is used to designate what shall be termed a holder for the gage pins, the same comprising a flat p-late provided with the upturned ends 2, between which the presser plate 3 is situated. The presser plate 3 is held in place against displacement by means of the end lugs Kit projecting therefrom fitting within the vertical slots 5 formed in the flanged ends 2 of the holder l.

Within the holder 1 and between the inner face thereof and the under face of the presser plate 3 is located a series of horizontally disposed independently slidable alined gagetingcrs or bars 6, which normally project a predetermined distance beyond the inner horizontal edge a thereof. These gagefingers, pins or bars are of a uniform length, and one end of each is reduced to a point, while the opposite end is preferably formed with a downwardly extended fiange, projection or scribing point 7.

rlhe presser plate 3 is held down onto thcupper surface of the row of slidable gagefingers, pins or bars 6 by means of the cover plate S, which plate rests on the flanged ends 2 of the holder 1, being cut away at each end to provide seals 9 for the reception of the shoulders or ears l0 upwardly projected from thejtlanged ends 2 of the holder l.

'lhrough each end of the cover plate 8 and the shoulders or ears l0 of the holder is extended a transverse bore 1l for the reception of a securing or lock pin 12, by means o'l which the said cover plate is locked to the ends of the holder l.

To obtain a. .friction-al hold between the slidable adjustable gage-pins, bars or fingers 6 and the presser plate 3, a layer 13 of felt or textile material is secured to the under face of the presser plate 3, and the said plate is held firmly pressed against the gage-pins, bars or fingers 6 to hold the same in locked position, by means of the tension thumbscrews 11i which work through the cover plate 8 and bear against the upper surface of the presser plate 3.

When assembled for use the scribing end of the liorizontal row of gage-pins, bars or fingers (S are flush with the outer horizontal edge (designated by the letter a) of the holder i, the pointed end of each of said gagepins, bars or fingers being projected a uniform distance beyond the inner horizontal edge a olfthe said holder l.

In using the improved gage for obtaining an accurate outline of the irregular surface of a piece of molding 15 for use in scribing a piece to be fitted thereto, the thumb-screws 14k are first loosened to partly relieve the pressure of the presser plate 3 onto the gagepins, bars or lingers (l, and the gage then pressed firmly against the outer surface of l the molding l5 until the inner horizontal edge a of the holder l bears against the same. 'VV ith the pressure. thus applied, Athe gage-pins, bars or fingers are gradually forced within the holder, the scribing ends of the said pins being forced a distance be-` yond the outer horizontal .edge a `of ,the holder to a distance equal to the elevations and depressions of the molding to be fitted. The thumb-screws 14 are then screwed down to force the presser plate firmly against the alined series of gage-pins or fingers 6 with sufficient pressure to hold the same securely locked against movement With the parts thus locked, the gage is placed on the piece to be fitted and the scribing points 7 ofthe adjusted gage pins `6 depressed or forced into the surface thereof to leave thereon an outline of the molding, by means of which the scribed piece may be readily Kcut or` sawed for an accurate fit or joint with the molding.

As an aid for readily determining rthe width of the gage molding, the cover v-plate 8 is provided adjacent each of lits horizontal edges with a scale of measure 16, the same being in inches to one-half of a foot measurement.

The described gage is simple of construc-y tion, accurate as to measurement, and readily adapted for moldings or mill work of complex outline.

lVhileby preference each of the gage pins` is provided with a scribing point for the formation of an outline marking on the surface ofthe piece to be fitted to the molding, it is apparent that a pencil may be employed for scribing said piece by following the outline formed by the ends of the gage` pins projected beyond the outer `horizontal edge a of the holder 1.

Having thus described the invention what, is claimed as new and desired to protect by Letters Patentis- 1. In a gage for the work of scribing,the combination with a holder provided with upturned vertically slotted ends, of a series of horizontally disposed alined gage pins independently slidable therein, a presser plate situated within the holder to bear onto the gage pins and provided with projecting flugs to .engage the vertical slots in the upturned ends of the holder, ears upwardly vprojected `from said ends, a cover .plate pro- Aplate for forcing the presser vplate againstvthe gage pins.

2. In a gage for the work of scribing,

Athe combination with a holder provided lwith upturned vertically slotted ends, of a series of horizontally disposed alined gage pins independently slidable therein, and each provided at one end with a scribing point, a presser plate situated within the holder to bear onto the gage ypins and provided with :projecting lugs to engage the vertical slots in the upturned ends of 'the holder, ears upwardly kprojected from said ends, a cover plate provided with cut outs or seats to receive the said ears, lock pins fitted within a transverse bore in the ends of the cover plate and the ears of the upturned ends of the holder fto secure the cover plate thereto, and thumb-screws working through the cover plate for forcing the presser :plate against the gage pins.

In testimony whereof l have signed my name to this specification Iin the presence of two subscribing witnesses.
