PATENT CARPENTERS GAGE.

Specification of' Letters Patent.

Patented Dec. 16, 1913.

Application filed June 19, 1913. Serial No. 774,614.

To all whom it may concern Be it known that I, HALvon E. HAUKOM, a citizen of the United States, residing at Minot, in the county of Ward and State of North Dakota, have invented certain new and useful Improvements in Carpenters Gages, of which thefollowing is a specification.

This invention relates to improvements in gages employed by carpenters for marking off mortises for looks, butt-hinges and the like, and its object is to provide a simple and efficient gage of this kind which can be readily set for different dimensions, and

which will accurately do the work for which it is designed.

These objects are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a plan View of the gage. Fig. 2 is an end view. Fig. 3 is a side elevation, partly broken away. Fig. 4 is a cross section on the line 4P4 of Fig. 3. Fig. 5 is a side elevation showing an extension gage applied to the stock of the device.

Referring specifically to the drawing 5 denotes the stock or body of the gage, the same comprising a block having a top longitudinal groove 6 in which a gage bar 7 is slidably mounted. One end of the gage bar carries a downwardly pointing scribing point 8, and the side of the bar has inch graduations 9 to enable the bar to be accurately adjusted to position the scribing point the desired distance from the forward end of the stock, said end being placed against the edge of the door or other part to be marked. Thus, if a line is to be scratched a distance of one inch from the edge of the part against which the front end of the gage is placed, the gage bar is slid outward until the one inch mark coincides with said end of the gage. The bar is then locked by a. means to be hereinafter described, and upon sliding the stock along the edge of the door or other part, the point 8 scratches a line exactly one inch from said edge. The stock 5 is also provided with a second scribing point 10 the same also pointing downward and projecting from the bottom thereof. This point is carried by a block 11 which is slidably mounted in a longitudinal recess 12 opening through the sides of the stock. One end of the block projects from the corresponding side of the stock and carries a pointer 13 which indicates on a scale 14 on Qsaid side of the stock. This scale starts at a shoulder or abutment 15 formed by a depending flange on the bottom of the stock, and extending transversely thereof. The pointer coincides with the scribing point 10, hence the latter can be accurately set the desired distance from the shoulder 15. This shoulder is adapted to be placed against the edge of the part to be marked by the point 10, to guide the latter in the same manner as the front edge of the stock guides the point 8, as hereinbefore described.

From the recess 12 a recess 16 extends through the bottom of the stock 5, The bottom of the block 11 has a rib l6 which slidably fits in the recess 16 and serves to guide the block. The point 10. depends from the bottom of the rib. The top of the block 11 comes slightly higher than the bottom of the groove 6, and said top has a groove 17 in which the gage bar 7 seats.

In the top of the stock 5 is a recess 18 which intersects the groove 6 and extends down to the recess 12. The top of the stock has a cross piece 19 through which a clamping screw 20 is threaded, the same being located so that its point may be screwed down against the top of the gage bar 7 to lock the same in adjusted position, and as the gage bar engages the top of the block 11, the latter is locked at the same time. Upon slackening the screw both parts can be readily adjusted in the manner hereinbefore described. A long graduated gage bar 21 is also provided to enable the device to be used as an extension gage, said bar taking the place of the gage bar 7 upon removal of the latter. The bar 21 has an eye 22 at one end to hold the point of a pencil for scribing.

I claim:

1. A gage comprising a stock having a longitudinal groove and a recess, a gage bar slidably mounted in the groove, a block slidably mounted in the recess and carrying a scribing point projecting from the stock, said stock having a shoulder to guide the scribing point, the block and the gage bar being in contact with each other, and means for clamping the gage bar and the block together.

2. A gage comprising a stock having a graduated side, and provided with a longitudinal groove and a recess, a gage bar slidably mounted in the groove, a block slidably mounted in the recess and having apointer indicating on the graduations of the stock, a scribing point carried by the block and projecting from the stock, said stock having a shoulder to guide the scribing point, the block and the gage bar being in contact with each other, and means for clamping the gage bar and the block together.

3. A gage comprising a stock having a longitudinal groove and a recess opening through the sides of the stock and a recess extending, therefrom and opening through the bottom of the stock, a gage bar slidably mounted in the groove, a block slidably mounted in the first mentioned recess and having a depending rib slidably fitting in the second mentioned recess, a scribing point extending from the bottom of the rib and projecting from the bottom of the stock, said stock having a bottom shoulder to guide the scribing point, the block and the gage bar being in contact with each other, and means for clamping the gage bar and the block together.

4. A gage comprising a stock having a graduated side and provided With a longiin the second mentioned recess, a scribing point extending from the bottom of the rib and projecting from the bottom of the stock, said stock having a bottom shoulder to guide the scribing point, the block and the gage bar being in contact With each other, and means for clamping the gage bar and the block together.

In testimony whereof I itffiX my signature in presence of two Witnesses.
