SPECIFICATION forming part of Letters Patent No. 418,553, dated December 31, 1889.

' Application filed May 25, 1889. Serial No. 312,112. (No model.)

To all whom t may concern:

Be it knownjthat I, CHARLES C. CHAMBER- LAIN, a citizen ofthe UnitedStates, residing at Muskegon, in the county of Muskegon and State of Michigan, haveinvented; certain new and useful Improvements in Cuspidors; and I do. declare the following'y to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same, reference being had to theaccompanying drawthereon, which form a part of this specification.

The invention relates to improvements in cuspidors, the object being to produce an article of the kind of paper or other suitable material rendered by any suitable means water-proof, and also preferably partially 'fire-proof, so that it will not easily burn and which can' be flattened or knocked down for the purpose of rendering it less bulky and occupying less space during transportation; and it consists in the points of construction hereinafter described, illustrated in the accompanying drawings,`and pointed out in the y claimhereto appended.

. Referring to the drawings by letter, A, Fig.

l, designates the circular blank of which the cuspidor is made' and which consists, preferably, of suitably thick paper rendered waterproof and, preferably, partiallyre-proof by any proper means, so4 that it `Will not burn readily unless thrown into a stove orfurnace. The said blank `has extending inward from it-sedge to the circular inner partition a, in-

` tended to form the base of the cuspidor, the

score-marks a d2, each score a forming an elongated V-shaped space orffigure a3 with the adjoining score a2, the vertex of which space is inward. The said spaces a3 are not radial to the blank, but all inclined at equal angles and in the same direction tothe radiiv that wouldotherwise bisect them, the scores a2 inclining sufficiently more than the scores. ct to make the spaces a3 V-shaped in the proper degree to permit said spaces a3 to be turned over on the intervening spaces 0,4 of the blank and form plaits therewith when the blank is operated upon by a suitable forming-machine.

The described construction is plainly and fully shown in Fig. l of the drawings.

Therblank when knocked into shape by a machine forming no part of this invention,

but which is subject-matter for an application of even date of filing herewith, appears as shownA in the side view, Fig. 3, in which the cnspidor tapers inward from the base a, as at B, to a circular neck b, and thence flares or inclines upward and outward, as at Z9', the part B forming a conical frustum below the neck b and the part bf forming a reversed conical yfrustum above said neck. In Fig. 3 the plaits are shown completed, the V-shaped spaces A3 being folded down on the intervening spaces a4. tant and, on account of the described inclination of the V-shaped spaces, incline upward from base to top ofthe cuspidor at equal angles, so that by twisting the top of the latter on the base thereof the inclination of the plaits can be largely increased and the cuspidor' flatten ed or knocked down, thereby decreased in bulk for the purpose of transportation,the paper having suflicient elasticity to assume its normal and proper shape when unpacked. The plaits may, when formed, have their sides or leaves held together by any proper means; but it is preferable to hold i The said plaits areequidisf' bind on each other, besides binding in the Y IOO last about two days, when they may Without cleaning be burned in a stove or furnace or otherwise destroyed.

The invention is simple and effective and 5 fully answers the purpose for which it was designed.

Having described my invention, l claim- The circular cuspidor-blank A, having the circular interior base portion a, and the in- Io clined equidistant V-shaped spaces a3, ex-

tending from the circumference to said base portion and composed of the adjacent inclined scores a a2, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
