DEPTH-GAGE.
. Specification of Letters Patent.
Application filed September 24,1910.
Patented Nov. 21, 1911.
Serial No. 583,599.
To all whom it may concern:
Be it known that I, FRED I. WALKER, aj citizen of the United States, and a residentof Babylon, in the county of Suffolk and State of New York, have invented anew and Improved Depth-Gage, of which the following is a full, clear, and exact description.
or blade frictionally engaged and slidable in keepers pressed from and to the opposite sides of the gage head.
The invention has in view a depth gage of this character in which the keepers are set back a substantial distance inward from the working edges of the head, and the metal at these edges brought well to the blade so that the gage head will rest evenly substantially throughout on the surface to which it is presented, and will not be raised there from when the head is laterally tilted.
Anotherobject of the invention is to provide for the frictional adjustment of one or more of the keepers to the blade.
A further object of the invention is to extend the metal of the head at the center well to the blade and provide the same with a graduated scale, and locate the said scale .so that it will serve to give the correct reading of the blade when the head in one position of use or the inverted position.
Reference is to be had to the accompany-- ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a front side view of a depth gage constructed inaccordance with my invention; Fig. 2 is a rear side view of the same; Fig. 3 is a cross-section of the gage on the line 33 of Fig. 1; Fig. 4: is an inverted plan of the gage as shown in Fig. 1; Fig. 5 is a cross-section of the gage on the line 55 of Fig. 1; and Fig. 6 shows the head of the gage inverted, as when the gage is used in close places.
The type of gage to which I apply my improvements is well known and embodles a gage head 5, and a gage'blade or stem 6, the head having a relatively long working edge 7 at one end, and a much shorter working edge 8 at its opposite end, and provided with a number of keepers 9 pressed to the opposite sides thereof in alternate order, in which the blade or stem is slidable and frictionally retained against accidental movement. The keepers 9 in thistype of gage generally adjoin the working edges, which prevents the metal of the head from being brought wellup to the gage stem at these points, and also causes the head to be raised from the surface to which it is presented when the head is tilted laterally. To over- The invention is an improvement in depth gages, particularly such as embody a stem;
come this and make the edges of the metal of the head to extend well up to the gage stem, I position the outer keepers 9 a substantial distance inwardly of the working edges, making these edges substantially con tinuous, which is very desirable in practical use. A gage of this type is often rendered useless by the loosening of the gage stem in the keepers, due to the wear. To overcome this and provide for the requisite friction on the gage stem, I split one or more of the keepers 9, preferably the long central keeper on the rear face of the head, as shown in Figs. 3 and 4, the slit in this keeper being adjacent to the body of the head so that the metal at this edge can be flattened out and brought well to the blade at the opposite side, as indicated at 10 (see Figs. 1, 3 and 6.) This central or intermediate portion of the gage head which is extended well to the blade is, as shown in Figs. 1 and 6, graduated in any. standard unit of measurement and fractional parts of the said unit. The blade 6 is also graduated in the same unit, the lines of graduation 11 extending, completely thereabout, so that they will at all times be presented to the scale when opposite thereto, in any position the blade is turned,
use when the head is applied to the blade as shown in Fig. 1, as well as applied when shown in Fig. 6.
In the drawings the blade 6 is shown to be marked every half inch from the lowerend by the graduations 11 and as the head 5 has graduations thereon of thirty-seconds of an inch, the half inches may be read directly from the blade and the fractional thirtyseconds may be read from the head, which will cause the projection of the blade to be read to a thirty-second of an inch.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. The combination of a depth gage head having keepers pressed therefrom to the opposite sides thereof, and a depth gage blade slidable and friction-ally retained in the keepers, with the keepers arranged inwardly from the working edges of the head, and wit-h the material of the head brought well up to the blade.
2. The combination of a depth gage head having keepers pressed therefrom to the opposite sides thereof, and a depth gage blade slidable within and frictionally engaged by the keepers, one of the said keepers being split whereby it may be adjusted to vary the frictional engagement with the blade.
3. The combination of a depth gage head having keepers stamped therefrom to the 0pposite sides thereof, and having working edges at both ends, and a blade slidable within and frictionally engaged by the keepers, the head having a scale arranged to give the correct reading of the blade for either of the said working edges.
4. The combination of a depth gage head having keepers stamped therefrom to the opposite sides thereof, and a depth gage blade slidable within and frictionally engaged by the keepers, the intermediate portion of the head at one side opposite one of said keepers brought Well to the blade and provided with a scale to give the reading of the blade.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRED ISRAEL WALKER.
