I FRANK L. WALTER, F DAYTON, OHIO.
Application filed August 15, 1918.
To rill Wit/NH may con/era Be it known that l, FRANK L. \Vnursn, a citizen of the United States, residing at Dayton. in the county of Montgomery and State of (lhio, have invented certain new and useful Improvements in Gages, of which the following is a specification, reference being had therein to the accompanying drawing.
T his invention relates to gages, and more particularly to a work supporting structure for use in connection with an amplil'ying gage. In amplifying gages and the like, the work or article to be gaged is placed between a. fixed work supporting derive and a movable work engaging mcmher, which work engaging member is so connected with an indicator that the movements of the work engaging member will be rea .lable, in amplified form. on the indicator. 'lhe work or article which is to be gag-ml upon a device of this kind varies gi'rcatly in character, and work supporting devices of different kinds are necessary in order that the work may be properly supported with relation to the movable work engaging member. Moreover, the repeated .:ont:-ict of the work with the work sup porting member, as the work is passed be tween the same and the work engaging member, tends to wear away the surface of the work supporting member and to form a depression or recess therein, which affects tl a arcnracy of the reading on the indicator.
One object of the invention to to provide in an amplifying gage or the like a work Sl.l] )])()1tlllg strlu-ture comprising a removable supporting member or base on which the work supporting devices proper are mounted, so that different bases may be 'n'ovidcd for different work and may be interchangeably secured to the gage.
Another object of the invention is to provide means for adjustably mounting a work engaging member on the l. ase so that when worn the member may be adiustedto bring a fresh or unworn portion of its surface into proper position with relation to the work engaging member of the gage.
It is also an object of the invention to provide a structure of this kind which will be very simple in its construction and which will be of such character that the parts Specification of Letters Patent.

will be held firmly in their positions, but can be readily loosened. for adjustment or removal.
In the accon'ipanying drawings Figure l is a perspective view of an amplifying gage showing one embodiment of my invention;
Fig. 2 is a sectional view of a portion of the structure shown in Fig. 1;
Fig. 4 is a side elevation of a portion of the device of Fig.
In those drawings l have illustrated the invention as applied to an amplifying gage, wrri-isponding in its main features of construction to the gage shown and described. in the application for patent filed by me August 23, 1917, Serial No. lfSTJISS, but it will be understood that the present embodiment of the invention has been selected for the purpose of illustration only and that the invention may be applied to gages, or similar devices, of various kinds, and that the invention itself may take various forms.
The amplifying gage of the above men tioned application, in so far as it is necessary to illustrate the same in the present application, consists of a standard 1, having secured thereto a supporting bracket 2. Adjustably mounted on the standard 1, preferably by mounting the same in a split sleeve 3, is a shank 4- upon the upper end of which is mounted a cross arm or frame 5. Mounted in one end of this frame and arranged above the bracket 2 is a movable work engaging member or pin (3, which is connected with an indicator '7 in such a manner that the movements of the work engaging member will be transmitted to the needle of the indicator. The connecting devices may be of any suitable construction, such as the lever arrangement shown. in the above mentioned application.
The work supporting devices are carried by the bracket 2 and, in the above mentioned application, consist of a flat plate rigidly secured to the bracket, but this plate can be used only with a. limited class of articles to be gaged and, in order that work SllpPOltlDg devices of different kinds may be mounted on the bracket 2, I have provided a removable base 8 which is adapted to carry the work supporting devices proper and which may be constructed to accommoflat face of the bracket is provided with a groove or channel 9 adapted to receive a rib '10 depending from the base plate and ex-' tending longitudinally thereof. The device for attaching the base plate to the bracket, as shown in the present drawings, consists of a screw 11 extending vertically through thebracket and into a screw-threaded socket formed in the base plate and, preferably, in the rib 10. In this manner, the base plate is readily removable and it will be obvious that any base plate comprising these broad features of construction can be applied to the bracket.
In that form of the device shown in Figs. 1 and 2, the base plate is designed to support a work engaging member or anvil, upon which, the work rests while in contact with the work engaging member or pin 6; As has been explained, a work engagmg mem-.
ber of this kind issubjectto wear and it is desirable that it should be adjustable to permit different portions of its supporting surface to be brought into proper relation to the work engaging. member. The work supporting member or anvil, as shown at 12, in Figs. 1 and 2, is so mounted on the base plate that it can be quickly and easily adjusted to different positions thereon, or entirely removed therefrom and a difierent member substituted therefor. In the con struction here shown, the base plate is provided in its upper surface with a longitudinal channel 18, in. which the lower portion or base 14L of the anvil 12 is mounted, and in V which itmay be moved lengthwise. It will be understood, of course, that the anvil may take any suitable form so long as the base its properly within the channel 13. The wmrk supporting member or anvil may be secured in adjusted positions on the base plate in any suitable manner, but I prefer a clamping device which can be quickly and easily operated. In the present instance, the base plate is so constructed that the vertical side walls of the channel 18 constitute clamping members which can be moved toward. and from each other to clamp or release the anvil. To accomplish this, the lower surface of the base'plate is so constructed that it will rest upon the supporting surface of the bracket 2 at its edges only, the intermediate portion being cut away, as shown at 15, so that it will not contact with the surface of the bracket, and, when, as in the present instance, the base plate is provided: with arib 9, this rib is of'such a depth that it will; not engage the bottom of its bracket and to be groove when the base plate is in its normal position. With the base plate constructed in this manner, the attaching screw 11 acts as an operating device for the clamping jaws or side walls of the channel 13, it being apparent that when the screw is inserted in the socket in the rib 9 and tightened down, the rib will be drawn downward toward the bracket and, inasinuch'as the edges 'of the base plate are held against movement, the upper edges of the side walls of the channel will be moved toward one another, thus bringing them into gripping engagement with the base of the anvil 12, the base plate having sufiicient resiliency to permit it-to be thus distorted from its normal shape. To facilitate the clamping action of the jaws I have, in the present instance, provided the corners at the junction of the side walls with the bottom of the channel 13 with grooves 16, as shown in Figs. 1 and 2. r
' It will be apparent that when'it is desired to adjust the anvil it is only necessary to loosen the screw 11', without entirely withdrawing it from itssocket, and after the proper adjustment of the anvil has been made to again tighten the screw and thus cause the walls of the channel to grip the anvil. Such a construction enables the base plate to be used indefinitely, as'it is subjected to very little wear. The work engaging member or anvil being a separable part of the structure, it not only can be ad justed as has been explained, but can be readily removed to enable another anvil to be substituted therefor on the base plate.
' In Figs. 3 and 1, I have shown a base plate 17 similar to the base plate 8 above described, but having means for carrying a different kind of work engaging device. This base plate is provided at its inner or rear end with an enlarged head or cross arm 19, which fits into the space between the shank 1' and the base plate proper, and in the rear of the work engaging device. This head, which preferably extends for some distance on each side of the base plate,
has a bearing surface 20 arranged obliquely to the plane of the work engaging device, and is provided with a T-shaped slot 21. This cross arm or head is adapted to carry a pair of tail stocks 22, which are adjustably secured thereto by means of bolts having their heads arranged in the slots 21, extending through the respective tail stocks and provided with hand nuts 23 for clamping the same in position. Each tail stock is provided with a'center pin 24; which is rotatably mounted therein and is, preferably, provided with a milled head 25 whereby it may be rotated. mounted in split bearings 26 which are provided with clampingscrews 27, so that they may, if desired, be locked against rotation. This type of work support is designed for The pins are, however,.
gaging cylindrical work such, for example, as a shaft, and serves not only to gage the size oi. the work, but also gage the same as to concentricity, because the center pins are caused to engage the centers at the ends of the work and as the latter is rotated any eccentricity thereof will be shown on the indicator.
The operation and manner of use of the invention will be understood from the foregoing description, and it will be apparent that I have provided a structure in which the base plate is readily interchangeable and in which the worn supporting devices may be adjusted, either to bring different surfaces into operative relation with the work engaging device or to accommodate the same to work of different kinds or sizes. The device very simple in its construction and is ot a strong durable character, which not only is not liable to get out of order or to be broken, but which will always support the work supporting devices in proper relation to the work engaging device.
While I have shown and described one embodiment ot the invention, I wish it to be luiderstood that I do not desire to be limited to the details thereof, as obvious modifications will occur to a person skilled in the art.
