IMPROVED CARPENTERS GAGE.

Specification forming part of Letters Patent No. 11,572, dated August 22, 1854.

To all whom it may concern.

Be it'known that we, HALCYON'SKINNER and WILLIAM GREENHALGH, of West Farms, in the county of Westchester and State of N ew York, have invented a new and useful Improvement in Combination-Gages; and we do hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings, forming a part of this specification, in Whichi f Figure l is a side View of our improvement; Fig. 2, sectional view of the same; Fig. 3, view of another side; Fig. 4, View of side opposite Fig. 3; Fig. 5, horizontal section; Fig. 6, perspective view.

Similar letters refer to like parts.

a is the frame of the instrument; b, fixed fence; c, gage-point; d, sliding fence; c, ad-

justing-screw; f, sliding gage-bar; g, sliding -fence; h, adjusting-screw; t', sliding fence; k,

sliding gage-bar; Z l m, gage-points; n, shoulder; o p, gagejpoint.

Our invention consists in the combination, into one convenient instrument, of several sliding adjustable gages, so arranged that various operations in carpentry hitherto requiringthe employment of several distinct and costly instruments may all be accomplished by the use of one of our improved gages.

In constructing our gages we make a grooved and slotted frame, a, in the form shown in the various figures. At the lower end of the frame a we attach a fixed fence, b, having a gagepoint, c, placed in the center of one side. The other extremity of the frame a is furnished on both sides with gage-points l l. The sliding fence d is made to fit the groove and slot of the frame a, and has a shoulder, n, which projects through the slot in the frame a to an even On this opposite side there is a gagepoint, o. rlhe sliding gage d and gage-point o are adjusted and secured in any desired position by means That portion of the of the adj ustin gscrew e.

groove in the frame a above and on lthe same side with d lis occupied by the sliding fence g and the sliding gagebarj'. The sliding gagebar f is slotted throughout its entire length, and occupies the inner or central portion of the groove. The sliding gage-bar f is armed at its upper end with a gage-point., 19. The sliding fence g is also slotted and moves upon and outside of f. 0n the opposite side of the instrument there is another sliding gage-bar, It, with point m, arranged and moving in the same manner as f. There is also another sliding fence, fi, arranged an dmoved in 'the same manner as g. The sliding fences g i and the sliding gage-bars f k are all adjusted and secured by one adjusting-screw, e. The various gage-points are so 'inserted that they can at any time be pushed out or removed `Whenever they become Worn.

It is needless for ns to specify the various ways in which our improvement is useful in carpentry, since every carpenter will readily recognizeits advantages. It may at all times be used in place of the ordinary gage., and also in place of all other double or special gages, since it combines the advantages of the Whole of them in the most convenient manner, besides possessing many more useful qualities not to be realized at all with the others.`

Our improvement is cheap, durable, and very simple, there being only two adjusting screws in its entire construction.

Having thus. described our invention, We
