Claims. (Cl. 183-73) This invention relates to caps for attachment to the access necks of liquid receptacles, for example, engine crankcases. Such caps contain filter material and are generally known as crankcase breathers.
Such breathers comprise two generally cup-shaped spaced metal members, one inside the other, between which is disposed woven wire or other air filtering material. Perforations permit air to pass into the space between the cup members, through the woven wire or other air filtering material and out. The inner cup member is adapted to fit over a tubular access neck and spring arms on the breather depend into the neck and resiliently engage the inner surface thereof. 7
The object of the invention is to secure the spring arms to the breather in a simple and inexpensive manner.
Accordingly, a pair of spring arms is formed integrally as a generally U-shaped member, the middle portion As a further alternative, the top of the inner cup member may have a hemispherical deformation to engage the middle portion of the spring to the outer cup member.
The breather may also have indentations in the upper part of the outer cup-shaped member to assist in locating and maintaining in a compressed state the said woven wire and to provide finger grips to facilitate handling of the breather when it is fitted to or removed from an en- The scope of the invention is indicated by the appended claims; and how it can be carried into effect is hereinafter particularly described, with reference to the accompanying drawings, in which:
Fig. 1 is a vertical section of a first embodiment of a crankcase breather according to: the invention, shown fitted on a tubular access necks.
Fig. 2 is an inverted plan of the breather in Fig. 1;
Fig. 3 is a vertical section of a second embodiment;
Fig. 4 is a detail plan of the inner cup member of the breather in Fig. 3;
Fig. 5 is a vertical section of a third embodiment;
Fig. 6 is a detail plan of the inner cup member of the breather in Fig. 5;
Fig. 7 is a vertical section of a fourth embodiment;
Fig. 8 is a detail section on the line VIII-VIII of Fig. 7;
Fig. 9 is a detail plan of the inner cup member of the breather in Fig. 7;
Fig. 10 is a vertical section of a modification of the breather shown in Fig. 5; and
'q 2,53 ,258 Patented May 2?, 1958 Fig. 11 is an elevation of Fig. 10.
In the first embodiment, shown in Figs. 1 and 2, the crankcase breather is made from inner and outer cu members 1 and 2 respectively which are metal pressings. The outer cup member 2 contains an annular woven wire filter element 3, and the inner cup member 1 is arranged within the outer cup member 2 in contact with the woven wire 3 and spaced from the top 4 of the outer cup member. The inner cup member 1 has a flange 5 with perforations 6 therein, and a top 7 with an opening 8 therein, through which air can pass to and from the filter element 3, and through the opening 8 depend the arms 9 of a U-shaped plate spring member 10 which has a fiat middle portion 11 adapted to contact the outer cup member 2 and connected to the arms 9 by re-entrant portions 22 of semi-circular formation which are disposed between the tops 7 and 4 of the inner and outer cup members 1 and 2.
Upon assembly, the outer periphery of the perforated flange 5 of the inner cup member 1 is gripped between the portions of a turned over edge flange 13 on the outer cup member 2. The diameters of the semi-circular portions of the spring member Ill are slightly greater than the space between the tops 7 and 4 of the cup members 1 and 2 so that the spring 16 is resiliently gripped between the inner and outer cup members 1, 2.
In the second embodment (Figs. 3 and 4), the inner and outer cup members 1, 2 are similar to those in the first embodiment except that the top 7 of the inner cup member 1 has two slots 14 for the arms of the spring member 18 and two slots 15 for the passage of air. The middle portion of the spring member 10 is con nected directly to the spring arms 9 and is formed with an undulation 16 so as to engage the tops 7 and 4 of both the inner and outer cup members 1, 2. The height of the undulation 16 is slightly greater than the space between the tops 7 and 4, so that the spring member 10 is resiliently gripped between theinner and outer cup members 1, 2 upon assembly.
In the third embodiment (Figs. 5 and 6), the flat middle portion 11 of the spring member 10 is connected directly to the spring arms 9. The top of the inner cup member has an upward hemispherical deformation 17, which, upon assembly of the inner and outer cup members 1, 2, resiliently engages the flat middle portion 11 of the spring member 19 against the top 4 of the outer cup member 2. In this form the slots 15 are replaced by opposed pairs of holes 18.
In the fourth embodiment (Figs. 7 to 9), which is similar to the third embodiment, the spring member 19 is in the form of a round wire 19 and the spherical deformation 17 of the top of the inner cup member 1 has a groove 20 to locate the wire 19 against the top 4 of the outer cup member 2. The arms of the wire extend through diametrically opposed narrow slots 21 in the top of the inner cup member 1 and there are also three diametrically opposed pairs of holes 22 for the passage of air.
In a fifth embodiment of the invention (Figs. 10 and 11), the outer cup member 2 is formedwith indentations 23, of which there are conveniently three, equispaced about the axis of the outer member 2 and extending from the periphery of the substantially fiat top part 4 to approximately half way down its wall. The indentations 23 protrude inwardly so as nearly to meet the wall of the inner cup member 1 and thereby retain the annular mass of woven wire 3 in position between the lower parts of the walls of the two cup-shaped members 1, 2.
The indentations 23 in the outer cup member 2 can be provided in any of the four embodiments of the crankcase breather previously described.
