JAMES TVINANTS TALLMADGE, OF BOSTON, MASSACHUSETTS.

EXU DATHU N GAP.

SPECIFICATION forming part of Letters Fatent No. 599,872, dated February 22', 1898.

Application filed November 1, 1897. Serial No. 657,100. (ModeL) To aZZ whom, it may concern;

Be it known that 1, JAMES Wnvxxrs TALL- MADGE, a citizen of the United States, residing at Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented a new and useful Improvement in the Manufacture of Exudation-Caps, of which the following is a specification.

My invention relates to exudation-caps as patented to me October 12,1897, No. 591,434; and it consists of mechanically joining the cap and nozzle without detriment to either flexibility or porosity. I accomplish this object by means of the stiffener and holder device illustrated in the accompanying drawings, in which Figure 1 is an elevation of my exudationcap mounted upon the outlet portion of a receptacle. Fig. 2 is a sectional elevation of the same upon the line a: to in Fig. 1. Fig. 3 is a detail view of a porous nozzle provided with my stiffener and holder. Fig. dis aview of said stiffener and holder. Fig. 5 is an edge view of said porous nozzle in its proper form for being adjusted in the apex of said cap, as shown in Fig. 1; and Fig. 6 is a perspective view of amodified form of stiffener and holder with porous nozzle folded about it.

Similar letters refer to similar parts through out the several views.

D represents the outlet portion of a receptacle of any desired size, shape, or material.

A represents a flexible impenetrable cap, preferably of rubber.

B represents a compressible porous nozzle, (which is not susceptible of hardening,) preferably of felt, provided with a stiffener and holder 0, preferably of aluminium wire, clasped around its middle, as shown in Fig. 3. The porous material B is folded with said stiffener and holder 0 at the line of flexure, as shown in Fig. 5. Thus formed, said nozzle B is adjusted in apex of said cap A. The stifiener and holder 0 keeps apex of said cap A in the rectilinear form of said nozzle B, and the tension of said cap Aholds said nozzle B in position. The lower portion. of said cap A is adjusted to the diametrical exterior of the outlet portion of receptacle D, all as shown in Figs. 1 and 2.

A straight bar 0' may be employed as a stiffener and holder at the crease-line in folded nozzle B, as shown in Fig. 6, instead of band shown in Figs. 3, 4t, and 5.

Either form of stiffener and holder above described prevents cap A from buckling, and being affixed at the neutral line of said nozzle B it does not interfere with the function of cap A or nozzle 13.

The flexible cap portion A acts as a hydraulic flexor, and the porous nozzle portion B acts as a combined stopper, conductor, and spreader, which will not exude until pressure is applied, no matter what position receptacle I) may be in.

This exudation-cap,being adjusted as above described to any suitable receptacle containing the requisite fluid, forms a combination more substantial and is manufactured at much less cost than the vulcanizing or cementing process of unification shown in aforesaid patent to me October 12, 1897, No. 591,434, which is an excellent construction, but expensive and difficult to manufacture on account of the felt charring by the heat required in vulcanizing. My present construction performs the same function, and is used in precisely the same manner, by applying (like a brush) said nozzle B to the surface that requires moistening, the extrusion being controlled by operator using more or less pressure.

I claim 1. In an exudation cap, the combination of the flexible, impervious, openended cap, the porous, compressible nozzle, inserted in the apex of the cap, and the stiffener and holder located in the cap transversely of the nozzle and engaging the sides of said cap, substantially as described.

2. In an exudation-cap, the combination of the flexible, impervious, open-ended cap, the porous, compressible transverselyfolded nozzle inserted in the apex of the cap, and the stiffener and holder located in the cap at the fold of the nozzle, and engaging the sides of the cap, substantially as described.

3. In an exudation-cap, the combination of the flexible, impervious, open-ended cap, the porous, compressible nozzle transversely-folded nozzle inserted in the apex of the cap, and the stiffener and holder located in the cap at the fold of the nozzle and extending around the same, and engaging the sides of the cap, substantially as described.
