Applicationiled September 4, *1923. Serial No. 660,808.
Thev present invention relates 'to metal' 185 issued October 31, 1911, and 1,405,670,
issued February 7, 1922, aredisclosed spacing elements. These devices are accurate where the spacings are not great, but errors are apt to arise when extended measurements are necessary and the resent invention is applicable to machines aving Veither vertical or horizontal slides adapted to move comparatively great distances and in which measurements of several feet down to thousandths of an inch can be determined quickly and with great accuracy.
the character described, which` may be supplied either as anattachment to be applied to machines or may be formed integral therewith without any material change' in the existing structurek ofisuchA machines.
` In the accompanying drawings f Figure 1 is a fragmentary front elevation of a milling and drilling .machine with the improvements a'` plied thereto,
Figure 2 is a ont elevation of the device.
' Figure 3 is an end elevation of-the device,
parts being shown in section.
Fi re 4 is a section taken on of Figure 2,
Fi` re 5 is'anV enlarged section taken on the lme 5 5 of Figure 2, y Figure 6 is an enlarged section taken on the line 6-r6 of Figure 2.
Figure 7 isa bottom plan view ofthe indif cator slide. In the present embodiment-'the invention is shownfand describedas an attachment. 'Referring to the' drawings,.the invention is shown applied to a milling and drilling machine 8, carrying work 9 mounted ,on the y usual transverse andV laterally` moving memv` -bers 10 land 11.A The device is applied to each 'of these' members vfor gauging. the amount of movementtobe given, and consists of a member. 12,.which in 'the present instance, is secured to each of the transverse and laterally moving members 10 and 11 by screws 13, as shown iii-Figure 1. An indicator slide in the form ofa base 14 is mounted in a s1ideway'15 formed in the fac-e of member 12 and extending the `full length thereof.
A further object is to provide a device of- Formed the member'12 subjacentvto the slideway 15 andcommunicatin a slot 16 in which. ositioning elements, preferably steelballs 1 are located.` Blocks '17 are secured upon either end of the member 12, whereby'th'e spacing balls are retained in f slot 16. The balls 17 have portions-ground away to form flattened, abutting surfaces 18. It will be evident to those skilled in Athe-art that the distance from center to center of these balls may be determined with great accuracy by varying the amount of material therewith is removed from opposite sides ofeach ball.
Referring now to Figure 6t will be noted that portions of the balls 17 project slightly `from the slot' 16 into the slideway 15, and are lreceivable in a centering socket 19 yformed in the underside of the indicator slide 14. Adjacent thereto and extendin "longitudin`al ly on the underside of the in icator slide 14 1s a groove 20 suiliciently deep to clear the balls 17, and preferably tapering toward its inner end. u
The indicator slide 14 is secured in the slideway 15 by lmeans of a screw clamp 21 carried thereby, and having a head 22 oper ating in a T-slot 23 formed in member 12.
ACoiled springs 24are carried in recesses 25 formed in the. underside of indicator slide 14 and are adapted to bear against the surface of slideway-.15. It is thus evident that when screw clamp 21 is loosened, the sprin s 24 force the rear end of the indicator sli e outward to free it from .the balls 17 and the v slide ma be moved to any Adesired position and again clamped, whereupon one of the vballs will sea-t itself in the socket y19 and thus position the slide.
The member 12 carries a scale 26, `the, markings of which are predetermined and arein alignment with the centers of the dierent'balls 17. An indicator 27 is pivoted on the slide, as shown at 28,V and provided with an outwardly turned end 29. .L scale 30 is in coacting relation to the pointer end of the indicator. The indicator 27 is normally held at one end ofthe scale, as
shownin Figure 2`by a hair spring 31.
' Secured on the supporting member is a' micrometer 32 detachably carried by a standard 33 that is mounted on a base 34. The
' standard 33 is .longitudinally ad'ustable by means of thumb screw 35 an clamping screws 36, passing throu h slots 37 and engaging the base k34, as sI own, to hold it i-.u adjusted positions.
It will be appreciated that the indicator slide 14 carrying the pointer 27 and the micrometer 32 constitute gauge elements.
The o eration of the device is as follows: The wor 9, being in position u on the member 10, the central or zero-mar ing of scale 30 is brought in registration. with theI zero, or a determined marking, of scale 26. The micrometer 32 is set at zero and the member 10 moved-until the anvil of micrometer 32 contactsthe outwardly turned end 29 of the indicator 27, and brings the indicator to the zero marking-of scale 30, as shown in Figure 1. The device is n ow in the initial position for taking a measurement. Totake a. measurement on the work of, for instance, four feet, six inches, and four hundred twenty-eig'ht 'thousandtlis, the' micrometer is set at the thousandths 'and thel indicator slide moved-until the four feet six inches is read on scale 26. The member 10 is now moved until the parts are brought to their initial position to determine the measurement' on the work 9. It is evident `that in securing lateral measurements the operation is the same, substituting member 11 for member 10...
From the foregoing, it is thought that the construction, o eration and many advantages of the l erein described invention Will be a parent to those skilled in the art, without fiirther description, and it will be `understood that various chan in the size, shape, proportion and minor etails of construction, may be resorted to without departing from the spirit or sacrificing any of the a advantages of the invention.
