G. FRASER GREASE PLUG Filed July 28. 1923 Zia/anion Patented June 30, 1925. f. a 1, I v I i "trated.
To all- .w/mm, it .may. cancer-n .1 1
Be it: known that: 1,} GEORGE ;FRASER, a citizen of the. 'United"States,,residingjat Topeka,.in: the county of: Shawnee and State of Kansas, have invented certain new and useful Improvements: in I Grease Plugs, of which .thefollowing. is. a specification.
V This inventionirelates. torimpro e ents in grease cups and imorerpar ticnlarly .to ithe. plugs employed therein for compressing ;or feeding the grease therefrom.
: Oneyobjectofitheinvention isvto provide a plug of the character described having self contained .means for. holding it against acci dentaldisplacement in any. of its: ,Yarious positions of adjustment; Other objects and advantages of the inventionwill be apparent from theifollowingdescription, taken in connection with theiaccompanying drawings, wherein one form'of' theiinvention is illus- In the drawings Fig. 1 is a sectional view taken through a grease cup,fshowinglla plug constructed in accordance with the present invention, operatively positioned therein;
Fig. 2 is a side elevation of the plug;
Fig. 3 is a top plan view of the plug showing the parts in the position they occupy when the plug is in position in the cup;
Fig. 4 is a top plan view of the plug showing the parts in the position they occupy when the plug is removed from the cup;
Fig. 5 is a bottom plan view of the plug; and
Fig. 6 is a sectional view taken on the line 6-6 of Fig. 3.
Referring more in detail to the drawings, the grease cup is designated 10 and may be of any of the well known constructions, the same being internally screw-threaded as at 11. The plug is designated in its entirety by reference character 12, and is provided with a cut out portion 13, which extends downwardly from the top of the plug to a plane slightly below the center transverse axis, the base 14 0f the plug being integral and cylindrical in shape, and of a diameter corresponding to the interior diameter of the cup.
Pivotally mounted upon the base portion 14-, of the plug, and substantially filling the out out portion 13 thereof, is a movable section 15. The pivot pin bears reference character 15 and may be at any suitable for n such as arivet, ,orrthedike... The adjacent facesfof; the main, ,portion. of the plug and the movablesectiorrlb thereof. areprbvidedi with two pairs of complementary recesses 17; and, 18, the former, whemtlie 1 plug 1 is assembled, forming a; triangular. socket "19 adapted to receive the end of agwrench or j the lil e, ,fo,r operating ;t heplug., I
The complementary recesses .18; receive the opposite ends of .a, coiled spring 20,2 which. interposed ibetween, the ,main,' part .of. the plug-and the movablejsection15; thereof, this spr n rma y; n in fi me h section 15' on its pivot, causing the end of said sectionagainst which the. spring bears to;- protrude beyond the normal circumference-of th e-pl-ug, ,as shown more clearly in Fig. 1. flin other words, the plug is expanded at this point, causingthe'gscnew threads theneofvto bind against thesides of the .cup by reasonpf. which the plugr is. held against accidentals displacement. As shown in the ..drawings,-- V the", plug i s,scr,ew threaded from 7 end to end. for engagement .WYltllthe screw threads of the cup, the screw threads on the tends completely through the latter from top to bottom and communicates at its lower end with the socket continuation formed in said base 14. From this it will be observed that the bottom of the socket 19 is fixed, the sides thereof being relatively immovable, while the contrary is true of the portion of the socket 19 which extends above the base 1 1 of the plug, this portion of the socket being formed by the complementary recesses 17. This arrangement is preferably such that the recess '17 in the movable section 15 coincides with the corresponding portion of the socket in the base 14 when said section occupies the position shown in Fig 3. This being true, the long side of the recess 17 in the movable section 15 assumes a position slightly offset inwardly of the corresponding side of the socket in the base 1 1 when the no section 15 is in the position shown in Fig. 4. In this manner undue binding of the parts 15 prevented during use of the wrench in the same as with the solid plug now in comapplying, removing or adjusting the plug. 'In other words, the plug may be operated in either direction with but one operation,
mon use. i s
It will be obvious to those skilled in the art that the present improvements are $115- mental sections, forminga'n externally screwceptible of various changes and modifications without departing from the spirit of the invention and it is not, therefore desired to limit or restrict the same to the particular t'orm or arrangement of parts herein illustrated, except where'limitations appear in the appended claimsp l5 I What I claim is A g e 11'.
