ADJUSTABLE ermine-COLLAR;

7 .To all-whom it may concern.

' is clearly shown.

Be it known that LELSTON A. Roor, a citizen of the United States of America, residing at Dayton, county of Montgomery, State of Ohio,.have invented certain new and useful Improvements in Adjustable SpacingCollars, of which the following is r 'a full, clear, andexact description.-

This invention relates to devices for ad justing the I'GlQtlVBdlStlIlCQ between two objects and more particularly for adjusting the relative distance betweentwo machine elements such as cutters, facers and the like.

In the general machine shop practice close adjustments have heretofore been arrived at by adding paper shims to the regular spacing collars. After this type of ad justment had been used in the machine for a short period, the paper shims would wear and thereby destroy the accuracy of the adjustment.

Other types of spacing collars have been used which include two collars of the male and female type, which when rotated relative to each other would tend to increase or decrease the combined width of the two. The main objection to the use of this type of adjusting collar is that the rotation of the cutters would sometimes tend to rotate the adjusting collars themselves and thereby destroy the original adjustmcnt thereof.

It is among the objects of the present invention to provide a device of small struc ture and of substantially great durability, which may in no way be affected by the operation of the cutters to destroy the adjustment of the same and which may readily be operated to change the adjustment between the cutters if desired.

Other objects and advantages of the present invention will be apparent from the fol lowing description, reference being had to the accompanying drawings, wherein a pre ferred embodiment of the present invention In the drawings:

Figure 1 is a view showing a shaft of a milling machine (not shown), this shaft having mounted thereon two cutting tools with the adjusting collar interposed therebetween;

t Fig. 2 is an elevational view of the adjusting collar;

7 Specification of Letters Patent. Patented Jan 1921 Application filed August 23, 1920. Serial No. 405,492.

Fig. 3 is a side view partly in section, the section being taken along the line 3-'3 of Fig. 2 and shows the adjusting collar in its expanded position;

screw an'd a portion of the collar show- 111" graduations on the screw.

neferr-ing to the drawings, 20 designates an an usting collar comprising flanges 21 and a web port1on22. Theflanges 21 are screw threaded at various points, five points being shown in the Fig. 2, each of these screw threaded portions being adapted to receive a tapered screw 23 capable of forcing the flanges apart when screwed therebe tween. In order to increase the resiliency of these flanges, the web portion 22 is provided with a series or holes or openings 24 which are shown concentric with the screw threaded portions of the flanges 21.

Referring to the Fig. 1, a machine bearing 25, support-s a shaft 26 on whichare mounted two cutting elements 27. lnterposed between these two cutting elements are two collars 28 which have the adjusting collar 20 substantially therebetween. A nut 30 tends to hold the entire assembly of cutting elements 27, collars 2S and adjusting collar 20 in position against the shoulder 26" of shaft 26.

'lVhen the operator desires to locate two cutting tools a certain distance apart, the tapered screws 23 are operated, which when screwed into the collar tend to force the flanges apart and increase the distance between the cutting portions, and when screwed out of the adjusting collar will permit the flanges thereof to spring back again and thereby tend to reduce the distance between the cutting elements 27. y

In order that equal spreading of the flanges may be obtained at all the points of adjustment, the screws are provided with graduations 31 adapted to aline with indices 32 on the flanges whereby the operator may turn all screws an equal distance as indi cated ,by the graduations.

While the form of mechanism herein shown and described constitutes preferred forms of embodiments of the invention, it is to be understood that other forms might be adopted, allcoming within the scope of the claims which follow:

What I claim is- 1. A spacing collar comprising'a ring provided with peripheral flanges; and means interpose'c'l between said flanges for increasing the space therebetween.

'2. A spacing collar comprising a'ring provided with peripheral flanges; and wedge shaped means interposed between said flanges for increasing the space therebetween. a

' 8, A spacing collar comprising a ring provided with peripheral flanges; and a plurality of screws interposed between said flanges, and operable to increase the space between the flanges. i V

4. A spacing collar comprising a ring provided with peripheral flanges; and a plurality of tapered screws interposed between said flanges, and operable to increase the space between the flanges.

A spacing collar comprising} flanges of tapered screws interposed between said flanges and equidistant from the web por- Y tions to adjust the relative distancebetween the flanges.

6. A spacing collar comprising flanges and spaced web portions; and a plurality of tapered screws interposed between the flanges andthe web portions for adjusting the" relative distance between the flanges.-

7. A spacing collar comprising flanges and spaced web portions; a plurality of tapered screws interposed between said flanges for increasingthe spaces therebe tween; an index markon the flanges and in alinement with the center of each screw; and graduations on said screwsfor indicating the distance each screw is turned, to obtain equal spacingbetween' the flanges.

In testimony whereof I hereto afiin my signature; '7 v a a JELs'roN asoor.
