DEVICE FOR RET A|N|NG AND APPLYIN-e LleulDs.

SPECIFICATION forming part of Letters Patent No. l116,659, dated December 3, 1889. Application filed July 1`6, 1889. Serial No. 317,727. (No model.)

Be it'known that we, JOSEPH L 'VVELLS and DEWEY A. COBB, citizens of the United States, residing, respectively, at Avalon, in the county of Cape May and State of New Jersey, and in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Devices for Retainingand Applying Liquids, &c., of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, of which- Figure l is a longitudinal section through one form of the device. Fig. 2 is a full transverse section, as on line :n Fig'. l. Fig. 3 is a longitudinal section through a modification.

Fig. 4 is a section through the exit-nozzle,

showing felt and cap securing means. Fig. 5 shows the cap and felt detached from the nozzle.

The nature of this invention is a recep-A` tacle for containing a liquid or pasty material, such as mucilage, mixed paints, duc.,

with means for gradually forcing small or slightly beyond the exit-opening, and may be readilyand conveniently applied by taking the vessel in the hand and rubbing, as by brushing,"upon the desired surface or object.

The invention consists, primarily, of a receptacle, preferably of tubular form, having a tight-fitting piston adapted to work by means of a rod passing through a cap upon one end of the cylinder, and having a Inilled head for rotating said rod, together with a foraminous exit-opening at the opposite end of the receptacle, whereby any liquid or paste placed Within the cylinder in advance of the piston may be caused to eXude through the foralninous exit in small quantity, and the mass projects slightly beyond the exit, Where it is retained by the cohesion, and whereby the liquid or paste may be then applied as desired. j

The invention consists, also, in certain features and details that will be hereinafter described and particularly claimed.

at the lower oreXit end.

Referring to the annexed drawings,rwhere in Fig. l shows the preferred form of the device, o, is a hollow cylindrical vessel, usually l as a convenient size-say five inches long and one inch in diameter-made of sheet metal or other suitable material, screw-threaded at the upper or larger end, and contracted, as shown,

The latter is provided with a series of minute. holes h.

. c is a piston, preferably of india-rubber, which is fixed to the ends of rods c', (two in the present instance,) the other ends of Which rods are secured to a head d with a central threaded bore e, through Which passes a ,threaded rod f. This rod extends beyond a screw-cap a', screwed onto the top ofthe cylinder, and is provided with a milled head g,

preferably projecting circumferentially from the cap. A boss h is fastened to thethreaded rod just inside of the cap.

The operation of and mode of using the dei vice are as follows: The cap a is removed and the piston and its adjuncts withdrawn from the cylinder. serted within the latter, and the piston, dac., replaced. Vhen desired to force through the foraminous exit aquantity of the liquid orpaste, the milled head g is rotatedl in the proper direction, which obviously forces the piston-head in or down the required distance; The substance Within the cylinder is thus caused to exude through the pores, and is retained by cohesion around and extending beyond the exit, as indicated by the curved dotted line In order to spread the substance The ,liquid or paste is in on the desired surface, the cylinder is taken j The defect, however, in that device is that IOO the gum hardens Within and upon the spon ge, and thus'closes the pores, requiring t-hat the vessel sha-I1 be kept inverted a considerable time before the mucilage Within Will liquefy that on the sponge. With our device the mucilage may be forced through the sponge.

We have mentioned that the exit end of the receptacle is foraminous. This may be a series of small holes or perforations, or it may consist of a piece of felt t' or other suitable porous material secured just within the exit end of the cylinder. This felt, the., when used is preferably in the form of a truncated cone. (See Fig. 5.) It is inserted at the upper or larger end of the cylinder, and is forced into tliemozzle. As a means to prevent the felt from being forced from the cylinder, We sometimes provide the nozzle with an internal ring or bead a2, against which abuts the enlarged inner end of the felt, as clearly shown in Fig. 4. rIhe external circumferential groove a3, arising from the formation of the bead, provides a means whereby a protective rubber cap j may be de# tachably secured over the nozzle. When forced over the latter, the edge of the cap will spring into the groove, and thus the cap be held in place. To remove said cap, it is merely forcibly Withdrawn from the nozzle.

This cap, when applied, excludes air from the cylinder and at the same time prevents exudation of the contents.

In Fig. 3 We show a modiiication of the de-l always Within the saine, as in the previouslydescribed construction.

We are aware of the fact that hypodermic syringes have been made withv a screW-rod1 3, but with thel and piston similar to Fig.

usual elongated nozzle or tube through which the liquid is forced. IVe do not, therefore, claim this construction as 11eW.\vhen such;

porting-cap, and the porous material-such as felt-confined Within said nozzle, so that the outer end of said material will be practically flush With the end of the nozzle, substantially as and for the purpose described.

2. The liquid or paste retaining and apply-V ing device consisting of the combination ot' the cylinder or receptacle having the exitopening, the perforated head or cap on the end of said cylinder, the piston, and the threaded rod adjustably connected With the piston and provided with the rotating head and the retaining-boss, substantially as described.

3. The liquid o r paste retaining and applying device consisting of the combination of the cylinder or receptacle having the exitopening, the piston, the 'threaded head, the rods connecting said piston and head, the cap a', secured to the top of the cylinder, the retaining-boss h, and the head secured to the end of said rod for rotating the latter, substantially as described.

4. In a device of the class recited, the combination of the receptacleprovided at its exit end with the internal bead and the external groove, the porous material, and the detachable rubber protective cap, the piston, the screw-rod provided with the head, and the d etachable supporting-cap, substantially as described.

In testimony Where-of We have hereunto affixed our signatures this 28th day of June, A. D. 1889.
