GUM-PLASTER.

SPECIFICATION forming part of Letters Patent No. 688,446, dated December 10, 1901.

Application filed May 20,1901. Serial No, 61,108. (No specimens.)

To all whom it may concern: _u

Be it known that Ϊ,Herman F. Stempel, Jr., a citizen of the United States, residing at Fort Madison, in the county of Lee and·State of 5 Iowa, have invented certain new and useful Improvements in Gum-Plasters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apio pertains to make and use the same.

The invention relates to gum-plasters— plasters for the treatment of gums.

Heretofore when it was desired to apply a plaster to the gum great difficulty was experi15 enced in causing the plaster to adhere to the gum, for if the gum were slightly moist the plaster would work loose or shift its position.

The object of the present invention is to provide a plaster which will securely hold itself 20 in the position in which it is applied whether the gum be moist or not. In fact, if moist the plaster will have a greater retaining or adhesive power.

With this object in view the invention con25 sists in a plaster for applying medicaments to the gum, consisting of an elastic cup having a convex inner surface, to which inner surface is securely fixed an absorbent lining for holding and retaining the medicament, 30 the device being of a size easily covered by the lips of the wearer.

In the accompanying drawings, Figure 1 is a view illustrating the application of the invention, and Fig. 2 is an enlarged vertical 35 sectional view through the plaster.

In the drawings, A denotes a cup made, preferably, of rubber, and B denotes a piece of absorbent material secured within the cup. The medicament is placed in the cup and the 40 cup forced against that part of the gum to which it is desired to apply it and will be securely retained in position by the suction due to the forcing of the air from out of the cup in the act of pressing it against the gum. The medicament may be applied to the cup in 45 othei· ways than by providing the cup with a piece of absorbent material. For instance, a piece of raw cotton made up into a little sphere may be supplied with the medicine, packed into the cup, and the cup then applied 50 to the gum.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily un- 55 derstood without requiring a more extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without depart- 60 ing from the spirit or sacrificing any of the advantages thereof.
