BRYANT H. BLOOD, OF HARTFORD, CONNECTICUT, ASSIGNOR T PRATT & WHZ'INEY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
REVERSIBLE GAUGE.
Application filed April 8, 1922.
To all whom it mag concern:
Be it known that I, BRYANT H. BLooD, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Reversible Gauges, of which the following is a specification.
This invention relates to plug gauges and particularly to an improved reversible plug gauge of the go and not go type.
auges of this type usually comprise a handle having a go gaging head on one end and a not go gaging. head on the 1 other end whereby the operator may conveniently first try the go gaging head and then the not go head if necessary.
In my improved construction disclosed herein I provide a improved gaging head comprising both go and not go sections.
. propose to mount such gaging head on a single end of the handle and to make the head reversible relative to the handle in a manner to considerably lengthen the life of 2 the gauge. It is accordingly an object of my invention to provide an improved reversible plug gauge of the type.
It is another object of my invention to provide an improved reversible gaging head 80 comprising three sections, the middle section thereof being the not go portion of the head and the two outer sections being g1 portions,
ore specifically it is an object of my invention to provide a plug gauge comprising principally a handle and a gaging head, the gaging head comprising a middle not go section and a go section preferably integral with each end thereof, and the 4 handle being adapted to be mounted on either end of the gaging head.
With the above and other objects in view, my invention consists in the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing. In such drawing annexed hereto and forming a part of this specification, I have shown one embodiment of my invention, but it will be understood that the same can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the inven tion, the claims appended to this specification being relied upon for that purpose.
Serial No. 550,748.
Referring to the figures of the drawing:
Figure l is a side elevation of an assembled gauge comprising my invention.
F 1g. 2 is a side elevation of the gauge handle.
Fig. 3 is a side elevation of the improved reversible gaging head.
Fig. 4 is a side elevation of the means for securing the gaging head to the handle.
Figs. 5 and 6 illustrate end views respectively of the handle and gaging head.
Referring more specifically to the drawing by reference characters, 1 indicates the handle and 2 the gaging head of my im-' proved reversible plug gauge. I have illustrated the gaging head as of tubular form and as adapted to be secured to the handle by means of a bolt 3.
The gaging head 2' comprises three sections, namely, a middle not go section a and two outer go sections 6 and c. As illustrated, the sections 6 and o are symmetrical, relatively long as compared to the middle not go section a, and are preferably integral with the said middle section a. It will be understood that the middle not go section a is of a slightly greater diameter than the go sections 1) and c and the sections are preferably spaced from each other by annular grooves 4. I
The gaging head 2 is reversible, that is, either end may be secured to the handle 1. Means is provided for preventing relative rotation and looseness of the head on the handle and such means preferably comprises intereugaging projections and notches in the abutting ends of such elements. Each end of the head 2 is illustrated as being provided with three V-shaped radial grooves or notches 5 for receiving similarly shaped projections 6 on the end of the handle. When the bolt 3 draws the head and handle into tight engagement, these interengaging projections and notches form a tripod support therebetween thereby preventing relative rotation and looseness between the head and the handle.
I preferably provide the gauge with a pilot member at its gaging end. As illustrated this member comprises a conical bushing 7 mounted on the bolt and adapted to be engaged between the head of the bolt and the gagingend of the head 2. The bushing 7 is also provided with a tooth 8 for seating as the not in one of the notches 5 to prevent relative iotajiaion of the pilot relative to the gaging For gaging purposes, the auge is assembled as shown in Fig. 1. n operation, the operator holds the gauge b the handle 1 and inserts the other end of t e gau e into the hole to he gaged, the pilot 7 assisting in this gaging operation- If the hole is of the proper size, the go section b will enter the hole but the no go section a will be too large to enter. In use, the go section of the auge, by contacting with the edges of the holes being gaged, becomes worn down much more quickly than the no go section and must therefore be frequently renewed. When the section b of the gauge illustrated has become so worn down, the bolt 3 may be removed and the gaging head 2 reversed end for end, that is, so that the handle is secured to the end of section b. The unworn section a then becomes the go end of the'gauge in the same manner as was the end I) and the gauge is thereby renewed to a working condltion equal to that of its original form. As will be obvious, because of this reversible feature the life of the gauge is doubled.
To assure proper positioning of the pilot member 7 sothat it will be concentric with the forward end of the gaging member 2, I provide the bolt 3 with a slightly enlarged portion 9 adjacent its head. This portion 9 is ground or otherwise carefully finished so that it will fit within the hole of the gaging member 2 and also within that formed in the pilot member 7. It will thus be seen that as the finished portion 9 of the bolt 3 enters both the pilot 7 and the forward end of the gaging member 2 that it serves to hold these two parts in acurate alignment.
What I claim is:
1'. A cylindrical gaging head of the go and not go type comprising three sections, the middle section being of aslightly greater diameter than the end sections and acting 2.
