Specification of Letters Patent.

Patented June 12, 1906.

Application filed December 22. 1904. Serial No. 237,907.

for applying the same to the surfaces to bepasted or cemented; and the object of the invention is to provide a device of this character of asimple and inexpensive nature which shall be adapted for long-continued use without liability of becoming clogged with the dried paste, the preferred form of the improved paste-applying device comprising a daubing and spreading means and a paste-receptacle, which latter may be replenished from time to time as the'same becomes emptied, so that the utility of the device is greatly increased.

The invention consists in certain novelfeatures of the construction, combination, and arrangement of the several parts of the improved paste-applying device whereby certain important advantages are attained and the device is rendered simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which serve to illustrate the invention, Figure l is an elevation showing a paste-applying device constructed according to my invention, and Fig. 2 is a similar view of the device with its cap or cover removed. Fig. 3 is an en- I larged fragmentary sectional view taken axially through the upper parts of the improved paste-applying device and illustrating certain details of construction to be hereinafter referred to.

In the views, 1 indicates a collapsible paste-receptacle, preferably in the form of a bulbof soft rubber or similar compressible substance, having its upper part provided with a reduced tubular integral nipple 2, within which is adapted to be held a tubular spreader 3, of metal, hard rubber, or similar substance, adapted by its insertion within the bulb-nipple 2 to prevent collapse thereof when the paste daubing and spreading means is in position, so that a secure attachment of said means to the bulb may be efiected, as will be hereinafter explained. Said spreader or thimble 3 is of sufiicient internal diameter to permit convenient filling of the bulb 1 from the collapsible tubes in which paste is commonly sold, and the upper end of the tubular spreader or thimble 3 is provided with a flange 4, outwardly extended and overlying the edge of the bulb-nipple 2 for retaining the spreader in position.

5 indicates a socket carried by the metallic shell or casing 6 of the paste daubing and spreading means and of an internal diameter adapted to receive within it the compressible bulb-nipple 2 for the attachment of the paste daubing and spreading means to the said bulb or receptacle 1, and said socket 5 is preferably integrally formed with said metallic shell or casing 6, screw-threads being spun or other wise produced in the walls of said socket, so that when the socket is in position over the bulb-nipple 2 the said screw-threads will sink into thecompressible material of which the bulb-nipple 2 is formed, as shown in Fig. 3, so as to securely hold the paste daubing and spreading means to the receptacle 1, while permitting of ready detachment of said paste daubing and spreading means when it is desired to replenish the receptacle.

The metallic shell or casing 6 is outwardly directed into an annular flange at its central portion, and it tapers at its upper portion into a conical integral nipple 7, over which latter is adapted to be slipped, as seen in Fig. 1, a cap 'or cover 9 of a size to house within it the paste daubing and spreading sponge or part 8, which, as seen in Figs. 2 and 3, is carried above the nipple 7, so that when said cap or cover 9 is in position the air will be excluded, and the paste within the pores of the spongy paste daubing and spreading part 8 will be prevented from drying and hardening and clogging the device for later use.

The paste daubing and spreading part 8 is preferably formed from a rounded piece of spongy rubber, the pores of which are adapted for the flow of the paste through them when pressure is brought to bear upon the of which is incased within the central portion The lower portion of the spongy paste daubing and spreading part 8 is extended down within the nipple 7 of the shell or casing and within said nipple is made to inclose or incase the supply-tube 9, a thread 11 or equivalent device being wrapped around said lower portion of part 8, so as to hold the same securely to the tube 9, as shown in Fig. 3, and for the attachment of the part 8 and tube 9 within the shell or casing of which the body portion is formed I provide within the hollow of said shell or casing, as shown at 12, a filling of cement or other plastic substance, by means of which a secure bond is effected between the part 8 and tube 9 and the shell or casing of the paste daubing and spreading means. This filling 12 is expanded within the hollow of the flange 6, so as to effectively prevent the accidental separation of the parts.

From the above description of my improvements it will be apparent that the paste-applying device constructed according thereto is capable of some modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A paste-applying device comprising a collapsible receptacle formed from soft rub ber and having a soft-rubber neck or nipple integrally formed on it, a shell having paste daubing and spreading means at its upper part and, at its lower part, an interiorlyscrew-threaded socket in which said nipple is adapted to be received and also adapted to receive paste from said collapsible receptacle, and means in the nipple for distending it and simultaneously holding the soft-rubber walls thereof engaged with the interior screwthreads of said lower part.

' 2. The combination of a soft-rubber bulb having an integral neck or nipple at its upper part, a tubular spreader of hard material inserted within said neck or nipple, and a tubular shell provided, at its upper portion, with' paste daubing and spreading means and, at its lower portion, with a socket, the walls of which latter have integral screw-threads for engagement in the said soft-rubber 'neck or nipple to contain and hold said paste daubing and spreading means detachably upon the bulb.

3. The combination of the casing or shell having at its lower part means of attachment to a paste-receptacle, a spongy part extended above said casing or shell with a lower portion housed therein, a paste-supply tube the upper end of which is adapted for communication with said spongy part and the lower end of which is adapted for communication with a paste-receptacle to which the casing or shell is attached and a filling within the I hollow of the shell or casing for holding the spongy part in relation thereto.

Signed at Cincinnati, Ohio, this 19th day of December, 1904.
