therein gishadmitted=through--the pad structure specific,conditions jorinstanceQitmambetshaped 553 more conveniently to fit the hand in certain cases and in order to enter narrow recesses into which the surfaces to be cleaned may extend. The applicator is shown as rectangular in shape, but this may also be altered to suit the work.
The hollow body of the reservoir is preferably made of fairly strong though pliable rubber or its equivalent, and is preferably molded in one piece in the form of a cup. The body may have a generally rounded top portion 4 and a skirt portion 5 the inner rim surface of which is flat at 6 adjacent which is a flat shoulder which runs continuously about the inside of the body. Suitable strengthening ribbing 9 may be formed either interiorly or exteriorly of the body or both,
as desired. A filler opening it is formed at the top, which is closed by a removable stopper H. The filler opening is preferably countersunk as at l2 to receive the stopper which is formed slightly oversize so as tightly to fit the opening. The body I is shown as normally completely closed at the bottom, by the rubber applicator and valve member or pad 2, the rubber of which may be of substantially the same consistency as that of the body. The member 2 may be attached at its edges to the surfaces 6 and l by suitable cement or by vulcanization or both. It is also possible to make the applicator pad and the body all in one-piece by suitable molds as is well understood in the art of making hollow rubber articles.
R ie'ferring further to the pad member 2 with which the present invention is principally concerned. This as will be seen from Figs. 2, 3 and 4 comprises a generally flat section of pliable material such as rubber, having a central web I5 and inner and outer marginal flanges l6 and H, the double flange forming a relatively stifi marginal support for the web extending continuously about the peripheral portion of the pad. The top and side surfaces of the top flange are formed substantially complementary to the surfaces 6 and 1 inside the skirt portion of the body to which secured as mentioned above. The web l5 due to its relative thinness is fairly flexible and is substantially imperforate throughout its area so as to hold the cleaning fluid inside the body. In one or more places, the web is slit as at l8 to provide retaining valve means. normally holding back the fluid but opening automatically when the body is squeezed or pressed inwardly at its sides in order to dispense the fluid onto the surface to be scrubbed. Intermediately of-the two portions which are slit to form the valve openings the web is transversely reinforced at the back as by an upwardly bowed or arched and fairly broad rib 20, the ends of which merge substantially with the web material and terminate close to the inner flanges I 6 but do not join such flanges. The arch shape of the inner rib 29 and the fact that the ends of the rib taper down to nothing and merge with the diaphragm are important features in that the face of the pad is held against excessive bulging and indentation whenever the device is not in use, and, during flexing of the pad in use, the ends of the rib, being flexibly hinged to theside flange to disjoin the flanges from the cup. If the ends of the rib were connected to the inner side portions of theflanges, then, upon flexing of the central or web portion, there would be a tendency for the flanges, to be pulled away from the complementary surfaces of the body to which attached. v
On the under or exposed face of the pad are a marginal flange U.
do not pull or twist the flanges, at least to such extent as would tend plurality of spaced ribs 25 preferably of rectangular section and with smooth bottom faces located in the plane of the bottom surfaces of the The ribs as shown, are of substantially the. same height as width (about /8" x /8 in a 2%" x 4%" pad), and extend from one end marginal rib to the other. Both outer corners of each rib, preferably, are fairly sharp, for cutting action. The central rib branches at 26 inthe region of each'valve slit [8 so as to pass around it, forming a circular pocket 26a as shown. The circular rib portions connect with other ribs 25 on each side as at 21 for bracing efiect. Laterally aligned. with the circular rib formations are transverse stiffening ribs 28 which extend in both directions from the pockets 26a to the side marginal flanges. The ribbing forms a series of elongated pockets which entrap fluid cleaner from the surface being cleaned and assist in uniform distribution of it.
To relieve the slits and permit them to open easily upon subjection to atmospheric pressure outside the web and sub-atmospheric pressure inside the reservoir, V-shaped recesses 30 maybe formed on the outside of the slit regions; the slits communicating with said recesses at their apices as shown in Fig. 6. The web stock may be thinner at the circular regions (adjacentthe' slits) than at other. regions, for the same effect, as suggested in Fig. 7. The pockets Elia-adjacentthe slits do not of course, have to be circular; this particular shape being selected only because it simplifies the mold. r
A modificationof the inner rib which stiflens the web it is shown in Fig. 5 wherein it will be noted that the rib (indicated 20a) is not of d ecreasing height toward its ends as previously ,de-' scribed, but, instead, continues across the web. substantially at'the same height as the upper flange l6. Ween so formed, the ends of the rib are severed from the adjacent flanges I Is as by cutting at 2% with .a' knife. This prevents dawnward bowing of the Web and rib am from pulling? portions of the fluid on the surface to be cleaned. are caught by the rectangular pockets provided by the longitudinal and transverse ribbing for gradual distribution over said surface. 'In case the fluid contains abrasive, such as French chalk, this is finally wiped off the surface with a cloth or chamois. f'
Referring to Fig. 5 it will be noted that, when pressure is applied to the sides of the body. i, the web and its ribbing bows outwardly and thus the surfaces of the ribs may be brought into forcible contact with the work independently of the side and end-flanges H. An advantage of this is that the corners ofthe ribs o'f the web which stay sharp notwithstanding long use can be used to cut material from the surface tobe cleaned.
