To all whom/it mayconcern:
Be it known that I, HARRY VoLIs, acitizen of the United States, and residing at Detroit, 7
in the county of YVayne and State of Michigan, have inventecha new and. Improved Gauge, ofwhiclr tl'ie following is a specificatlon.
This invention relates to gauges for accurately determining the interior diameters of cylindrical holes andthe distances between opposed surfaces, and its objeotis to a provide a measuringinstrument of this character which shall be simple in construction,
which shall not be liable toget out of order, and which shallhe accurate.
This invention consists of a body provided It further consists of 'raduated members.
attached to the shaft and to the body whereby theanumber of rotations and the angles ,ofrotations may be indicated.
It also consists in-the details of construc tion illustrated in the accompanying drawmg and particularly pointed out in the claims.
In the accompanying drawing, Fig. l is.
an elevation of this improved gauge. Fig. 2 is a section on. the line 2-2 of Fig- 1. Figs. 3, 4E and 5 are sections on the lines 3-3, e-.4t and 5--5 of Fig. 2. Fig.6 is a perspective of one of the blades. Fig. 7 is a perspective of an auxiliary gauge balm.
Similanrefcrence characters refer to like parts throughout the several views.
The body 1 of this gauge is preferably cylindrical and is formed with any desired number of radial slots in which the blades 2 are mounted; These blades are preferably opposite to each-other in order that their outside measurements may be checked by means of ordinary micrometer calipers. Each of thesegbla'des is preferably U-shaped; incross sectionand its parallel sides areformed with the inclines 3 to be hereafter described.
.lWithin the blades are springs preferably formed of the leaves 4, 5 and 6, one of which has inclined projecting ends, 7 which are.

- adapted to engage the shoulders 8 formed in the body at the inner ends ofthe radial slots.
Attached to the outer end of the body is adisk 10 which is also formed with the shoulders 8 which are engaged by these projecting ends 7 of the springs. While this ilate may be attachedto the body in any desired inanner,-I prefer to use screws 12.
The body has a tubular extension 13 in which isjournaled a shaft 14% whose outer end 15 is also journaled in the disk 10, and
this shaft is formed with two groups of threads 16 and 17 which are of reversed pitches. Mounted on each one of these groups of threads is a head 18 internally threaded to fitthe threads of the shaft 14' and. provided with radial projections 19.
having inclined outer surfaces adapted to engage the inclined surfaces 3 of? the blades 2.
It will be noticed that when this shaft 14 is turned in onedirection the heads 18 will be separated and the inclined. surfaces of the projections 19 will slide on theinclined surfaces 3 of the blades 2 and thereby move these blades radially outwardly- In doing so the springs within the blades will be flexed, their ends 7 engaging the shoulders 8..as before stated, and so when theishaft is turned inthe opposite direction these springs.
will force the blades inwardly. Vihen the parts are accurately made these blades will move outwardly in such a manner that their outer surfaces will always remain parallel to the. axis of the shaft and the outside measurements at bothends of opposed blades will be the same.
The tubular extension 13 is formed with threaded portions 21 and 22. A tubular handle 23is screw-threiuled on the portion 21 and a sleeve 2a is screwed onto the threaded. portion 22 of the. extension. When this sleeve is turned on. the tubular extension the graduations 27, seen through the window 26 in thehandle 23 (Fig. 1) pass the line 25 on the tubular extension 13 and at the same time thesleeve moves longitudinally of the graduations adjacent this line 25. The pitch of the threads 16 and 1.7 is preferably the same as the pitch of the threaded portion 22 of the tubular extension and of the sleeve 24: and this pitclris indicated by the graduations on the tubular extension 13 adjacent the .line 25, so that the inner edge of the sleeve-2a will move longitudinally of the tubular extension the distance between graduation lines thereon for each rotation and the angular distance that this sleeve is rotated will be indicated by the gradnations 2T thereon.
I also form internal threads in the end of this tubular extension 13 and screw a small hollow plug 31 into this extension. The inner end of this plug holds aball bearing 32 against a shoulder 33 on the shaft 1 1-, although it will be understood that this ball bearing may be omitted. The outer portion 34; of this shaft may be threaded to receive a sleeve 35 which positions a second ball bearing 36, slidable on the shaft, so that when this sleeve 35 has been properly adjusted the shaft 1e will be absolutely prevented from moving endwise any appreciable amount.
In order to turn the shaft T have mounted a knob 40 on the end of the handle 23, holding it in position by means of a flange 11 on the handle. This knob screws onto a threaded end 42 on a forked member 13 which is seen in end elevation in Fig. 3, and extending into the slot 44 in this forked member is a block as which may be secured to the shaft and to the sleeve 35 by means of a pin 46 or in any other desired manner. When the knob 40 is turned this forked member 48 will turn with it and rotate the shaft through this block 45. The rear end 47 of the sleeve 24 is similarly forked; in fact, the same view will be had when looking in either direction from the line 3-3 of Fig. 2. The forked end 4:7 of the sleeve 24 receives this block 45, and the sleeve is therefore rotated by means of this block whenever the knob 40 is turned and the sleeve may travel along this block because of the threads on the end of the tubular member.
It will therefore be seen that the blades 2 may be moved freely inwardly and outwardly by simply turning the knob 40 and that the endwise movement of the shaft is prevented, but the endwise movement of the sleeve 2a is not interfered with, so that the graduations which are read through the window 26 always correctly indicate the out side measurements of this instrument.
It will be understood that the number of these blades may be varied to meet the various requirements and that the details and proportions of' the various parts of this instrument may be changed by those skilled in the art without departing from the spirit of my invention as set forth in the claims.
Vhen this instrument is to be used for measuring threads an auxiliary bar 50 provided with threads 51 and pins 52 may be mounted on the blades 2, which in that case are provided with small holes 53 to receive these pins. Any other desired type of auxil iary bars may be employed and when smooth bars are employed, the range of measurements capable of being performed by an instrument of this character may be greatly increased so that one instrument may be used for measurements between considerable limits.
I claim 1. In a gauge the combination of a hollow cylindrical body having a radial slot, a shaft rotatably mounted in the body and having two groups of threads, heads threaded on said threaded portions and having projections inclined to the axis of the shalt registering with said radial slot, a blade mounted in the slot and having inclined surfaces engaging the inclined projections on the heads whereby the blade is forced outwardly when the shaft is turned in one direc tion, and a spring to force the blade inwardly when the heads are moved in the opposite direction.
