This invention relates to brushes;v and more particularly, to a brush adapted to be used in connection with a pan greasing ma'- ,l chine commonly used in connection with J Jf greasing pans in the baking industry. f f
rlhe prime object is to prevent grease that is normally fed through the hollow stem or sleeve onto the brush from leaking onto the n Nmachine during the feeding process.l VAs usually used, the grease is melted and fed into a grease pump freni which it `is'forced through a hollow sleeve onto a brush head, A foot puinp is usually utilized, as a continu-y Q A fous feed is not necessary. Under these conditions due to the fact that the brushliead is usually made of wood 'andra close fit canrnotrbe obtained between the metal sleeve and the wooden brush head,the grease has -a tendency to iow back along` the outside of the sleeve onto the machinery, creating` a very unsightly and undesirable condition, at the same time providing iiivadet'iuatey lubrication for the brush head. 4 n V., ii my inventiointliis condition is impos-V sible due to my providing seals in the brush. to overcome these objections. s
Another object isto provide astronger and more durable construction between the brush head 'portion` and the grease feeding mecha'- nisin. l
Gther objects will be disclosed in the speciiication and claims forming a part of this application. Y A Y In the drawing: f e g Y, 1
Figure 1 is a sine elevation of-tne greasingapparatus in connection with ay .pain a portion of the pan. being broken away;
Figur-e 2 is a side elevation kof the greasing apparatus, with a vertical section taken l:
through the brush head; and y Figure 3 is a bottom plan ofthe brush portion. y Y
Referring to the drawing in whichA like parts are designated by similar numerals:
' Numeral l designates a dough pank ofthe usual construction which iiiust be greased before receiving the dough. Numeral 5 desig` nates a wooden brush head havinga bore 6 extending therethrough, the upper end ,7 of
L the bore 6 being of smaller diameter than the lower end 8; VBristlesll are secured Iinthe Outer periphery 1()y of the hea-d'5 byk means of staples 11 or other suitable means. A metal vtube 12 "having its upper end 13 conforming` to the upper end 7 of the bore 6 Ais forced into 55V the bore 6., A shoulder 14 is formed yon the tube 12'andadaptedfto fitV closely against a similar shoulder l-,forined inthe bore 6 due to the lowerk portionofthe'bore being cut "so lThe upper 'endfof the tube 12 is. swedged outwardly to hold thefsameirinlyrin posi-k tion. `A.,groove 16 is formed in the bottom yface 17 of the bruslilhead k5 and extends'into the bore. i Ay hollow spindle 18, having'a 65' collar 19fsecuredthereto andkeys 20 (formed -f [on ,oney face 'adapted to engage the groove' 16, causes 'Y the brush head 5to rotate ,with the spindle 18X The collar` 19is spaced a suii'- cient distancefroin the endof the spindle 18 7 i so'tli'at Va close lit can always be maintained between f the end'offthelfspindle 18 yand the y shoulden 14 and yet enablek the keys y20 to engage'fthe groovef16. Y The spindle- 18 kis i. supportedin bearingsg21and 22 in any suit- 75 e able manner,` and has a gear 23V which may be attachedto'any well known drive means,` A- ballbearing 24-is positioned on the spindle 18'directlyabove the bearing 21.
Underf this 4construction a grease 'seal is so formed 25 by the swedgingofthe sleeve 12, whic'liiat'the same time draws the shoul dery 14' tightlyjagainst the shoulder 15 forni,-
' ingja secondgrease seal26glf'l`he lower pors -tionof'thevtiibe 12 forms a vclose sliding it -85 s withtlie spindle 18 and the ,end of the spindle`18` lits tightly against the underside of the shoulder 14.15 Since lboth the tube 12 and spindle 18 are of metal, the ysaine may be `machined toa very-close lit which is not true no where `metal is contacting kwith wood, which is they case under the old construction; s
Underv my construction, a film of grease ywillaccumulate from lthe'shoulder14 to theV lower end of the'tubefk12 forming a seal,` the 95 grease formingthe film which wouldy not be true wherefthe metal was contacting with the wood since the wood would vhave a tendencyto absorbthegreasa y Y v'As' actually used, thel grease will be firstv 100' melted and forced under pressure by means of a hand pump through the spindle 18 through the tube 12 until it reaches the brush bristles 9. It is evident that it is literally impossible for this grease to work back around the tube 12 and spindle 18 due to the seals described. A,mueh superior construe# tion is obtained by'having the groove 16 in the lower face of the brush head instead of having this feature on the interior of the Y bore 6, as a more positive locking is obtained and the same may more easily be formed in the head 5.
It is obvious that the subject matter of my F invention may be utilized in ways other than illustrated in my drawings, and I do not limit myself tothis structure, but include means of accomplishing the saine result which may fall within the scope of the claims appended hereto.
What I claim is:
1. Pressure grease brush for greasing pans and thelilre comprising a brush head and a conduit for supplying the grease thereto,
said conduit being divided in said head, the
upper part being a tube fixed to saidV head, s
and the lower part being a spindle for rota-t-` ing said brush head, said tube telescoping with sliding sealing fit into said spindle. 3e
and thev like comprising a brush head and a- Q.' Pressure grease brush, for greasing pans conduit for supplying grease thereto, said conduit comprising a tubeixedly fitted in sealing contact with the walls of a bore in ,the brush head, and a spindle extending into 'a counter-herein said head, said tube teleseoping with sliding sealing fit into said spindle.
Pressure grease brush for greasing` `and the 'like comprising a brush head having a bore extending therethrough and an enlarged coaxial eounter-bore forming a shoulder, a tube positioned in said bore having a collar 'adapted to seat on said shoulder and -orin a seal, a spindle extending into said counter-bore, in which said tube teleseo .es with sliding sealing lit, and interdigitating means on said spindle and said head for causl ing the two to` rotate together, said top and said spindle forming a conduit for feeding grease under pressure to the brush head.
Ll. Pressure, grease brush for greasing pans` and the like comprising a brush head having a bore extending therethrough and an enlarged coaxial counter-bore forming a shoulder,- a tube positioned in said bore and havin a collar adapted to it on said shoulder an form a seal, the top portion of said tube being swedged outwardly into intimate contact with the brush head to form a seal, a spindle extending into said counter`bore, in "which, said tube telescopes with sliding Sealing lit, and interdigitating means'on said spindle andY head for causing the two t0 rotate together,said tube and said spindle orming r a grooveformed in said head to cause the two to rotate together, said tube and spindle being adapted to feed grease under pressure to 'said brush head.
In testimony whereof I affix my signature.
