LAYOUT DEVICE.
Application filed September 9, 1919. Serial No. 322,632.
T 0 all whom it may concern: 1
Be it known that I, CLIFFORD E. HAwKns, a citizen of the United States and resident of 183 Midwood St., Brooklyn, in the county of Kings and State of New York, have 1nvented certain new and useful Improvements in Layout Devices, of WhlCll the following is a specification.
This invention relates to layout devlces, that is, a tool for laying out work on a plane surface and has for an ob ect to 1ncrease the accuracy of work of this character, facilitate the operation and ncrease the speed in laying out Work of this character. These objects are obtained by the construction shown in the accompanying drawmgs in which, Figure 1, is a plan vlew of my 1mproved layout device, Fig. 215 a side elevation, Fig. 3 is an end elevation, Flg. 4 1s a detail partly in section and Fig. 5 1s a detail of an extension for the stand of the instrument.
In laying out work to be machined lines are transferred from the drawing to the work and at the intersection of these llnes center punch marks are made by hand to spot the drilling of holes, to mark the llmits of a machining operation etc. The pres ent invention provides for spotting these positions on the work by a micrometer adjustment directly from the lines of the drawing and provides a means whereby the center punch will spot the position wlth absolute accuracy. This is an important feature of the invention as it is impossible, by hand, to position a center punch absolutely perpendicular to the surface on wh ch it is used. It is also superior to center punches with a guide inasmuch as it is located with a micrometer adjustment with absolute accuracy and without regard to irregularities on the surface on which it is used.
This layout device'consists of a surface plate 11 to which the four posts 12 are secured. On one side these posts support the slide bar 13 and on the other side theysupport the slotted bar 14. Across these two bars the slotted bar 15 is placed snugly fitting a groove in the saddle 16 which is maintained at right angles to bar 14 by a T nut similar to' 18, Fig. 4 engaging the slot 19 in this bar. Bar 15 supports the slide 17 which carries the main part of the mechanism. A lead screw 19 is provided in the slot of bar 14 which is operated by handle 20, an index 23 being provided to show the extent in decimal fractions of-its operation. This screw engages the T nut on the under side of the saddle 16 and thereby moves cross bar 15 back and forth in response to handle 20. A similar lead screw' 21 is provided in slot of bar 15 operated by handle 22 with a micrometer index 24 to show fractional movements. On the slide 17 a nut 18 is provided engaging with lead screw 21, hence this slide is operated back and forth in response to handle 22. This construction is equivalent to a compound slide rest Well known in certain classes of .to be marked is placed on the face plate 11,
and the sides of the article may be positioned against the guide bars 51 and 52 on the face plate; the center punch 31 is replaced by a set plug similar to 55 and positioned relative to the base line from which the dimension is to be read. Set plugs of this kind are well known in the tool-makin art, consisting as shown in Fig. 4, of a comcal point with a flat side, this fiat side can be accurately sighted on the base line from which the dimensions are read. The lead screw 20 is now operated until the graduated scale 25 and the index 23 measure off the dimension required, this locates the position in one direction. This'operation is repeated with reference to moving slide 17 from another base line according to the di mensions indicated by the scale 26 and the index 24, this locates an intersecting position upon imaginary lines drawn from two sides and thus accurately locates the position for the center punch without scribing the work and without disturbing the setting of the center punch after it is obtained.
The set plug is replaced by the center punch in sleeve 34 and atap from the ham- Iner locates the point.
The extension 35 is positioned horizontally by the knuckle 61 on hinge 36, this part, however, is free to turn upward in the arc of a circle, the hinge member being cut away at 62 for this purpose the angle through which it moves being indicated by the protractor 37 secured in place by the Patented Mar. 8, 1921.
that may be protruding from the work inserted below. This movement also enables the work to be quickly and easily inspected and forms a yielding connection in case the I punch 31 is accidentally obstructed.
This gage also provides for measuring angles about a center located b punch 31'. This is secured by the horizonta protractor 4.5 which carries the plate 48 Fig. 4:, and is arran ed to move about the axis of punch 31. he zero mark of the protractor corresponds to a zero mark on 35 (not shown) when in the position shown in Fig. 1. Angular variations in either direction can thus be easily read. An adjustable extension 42 is secured to this plate by the screw 44 engaging the slot 43 in extension 42. A sleeve 41 similar to sleeve 34 is inserted in the end of 42, in which sleeve a punch similar to 31 may be inserted. This punch can, there. fore be used to accurately set off angles as indicated by the protractor 45 at various radii about'a centerwhich is located by the micrometer adjustment. The supporting posts 12 may be unscrewed in the middle and extensions 12 Fig. 5, inserted to lengthen these posts when it is desired to increase the height of the punches above the base plate.
Having thus described my invention, I claim: a
1. In a layout device of the class described, a base plate, supporting a stand, a movable carriage on said stand supporting a spring retrieved center punch, means whereby said punch may be moved at an angle to said base plate and means for adjusting the position of said carriage in two directions.

carriage, a plurality of micrometer screws, said screws arranged to move said carriage on said supporting stand, a spring retrieved punch supported by said carriage, means for operating said micrometer screws for positioning said carriage in two directions and means whereby said center punch may be moved angularly in a vertical plane.
3. In a layout device of the class described, a base plate supporting a stand, a'movable carriage on said stand supporting. a 'center punch, micrometer means for positioning said carriage in two directions at right angles to each other, means whereby said punch may be moved angularly in a vertical plane, and an index to show the position of said punch.
4. In a, layout device'of the class described, a base plate supporting a stand.
a movable carriage supported by said stand and supporting a center punch, a set plug, a horizontal protractor having the same axis as said center punch, an adjustable extention arm secured to said protractor and adapted to support said set plug.
5. In a layout device of the class described,
, a base plate supporting a stand, a movable carriage supported by said stand and supporting a center punch, a set plug, a protractor having the same axis as said center punch, an arm secured to said protractor and adapted to support said set plug, micrometer means for positioning said carriage in two directions and means whereby said set plug may be positioned by said protractor.
6. In a layout device of the classdescribed, a base plate supporting a stand, a movable carriage supported by said stand and supporting a center punch, a protractor having the same axis as said center punch and supporting a set plug, said carriage being movable in a horizontal plane, and means whereby said center punch and set plu may be moved in a vertical plane.
S igned at Brookl n, in the county of Kin s and State of ew York this 3rd day of ept. A. D. 1919.
