HERMAN MILLER, on NEW YORK, N. Y.-

IMPROVEMENT IN CANS FOR PAINT, &c.

Specification forming part of Letters Patent No. 145,440, dated December 9, 1873; application filed November 22, 1873.

To all whom it may concern Be it known that I, HERMAN MILLER, of the city, county, and State of New York, have invented an Improvement in Cans for Paints and other Materials or Liquids, of which the following is a specification:

This invention, like that described in Letters Patent No. 136,085, issued to me February 1S, 1873, relates to cans the lids of which are detachable, and are capable of being tightly or hermetically closed without soldering them to the body of the can; and the latter is made to present a wide mouth, having an extended bearing-surface for the lid, free from all liability to stick, by constructing said mouth and lid to have a cone-like valvular fit, the one upon or over the other, and so that, while the contents of the can may be preserved from outside exposure, every facility is afforded for the repeated opening and closing of the can. This invention consists in a combination, with a conical or tapering male valve-seat at the mouth of the body of the can and female valve in the lid, of a screw-thread spun or wrought in said body, and corresponding screw-thread in the lid, whereby an extended and close valular fit of the lid and body is more perfectly obtained, and but little, if any. cement is necessary to efl'ect a hermetical closing of these parts; also, the lid is securely held to its place.

Figure 1 represents a side view of a can constructed in accordance with my improvement; Fig. 2, a similar view of the upper portion of the body of the can with the lid removed; Fig. 3, a sectional view on a larger scale, showing the upper portion of said body and lid fitted thereon in profile.

Similar letters of reference indicate corresponding parts.

A is the body of the can, of cylindrical shape,

and having its mouth portion 1) made to contract or curve inwardly in an upward direction, so that said mouth portion constitutes a conical or tapering valve-seat, over which the lid B, that is made with a correspondinglyshaped female portion, (1, fits throughout the depth of the seat I), or thereabout. Spun or wrought in or around the outside of the body of the can, below said valve-seat, is a screwthread, f, and a corresponding female screwthread, g, spun or wrought in the lid below the valvular portion d, so that, when the lid is fitted to its place on the body and screwed home by means of the screw-threads f and the valvular portions I) d are brought in hermetically close contact, although, if necessary, or to yet more perfectly insure this, the interior of the surface 61 may be previously smeared with paint or cement of any suitable description.

hen the can is formed with a seam up it, as will usually be the case, then the meeting edges of the valvular portion should be rolled with a scarf-joint to give a smooth and unbroken surface.

I claim- The combination, with a conical or tapering male valve-seat, I), at the mouth of the body of the can, and female valve d in the lid, of a screw-thread, f, spun or wrought in said body below the valve-seat b,and corresponding screw thread 9 in the lid, substantially as shown and described.
