-O|NTMENT OR PILL SLAB.

PECIFICATION forming part of Letters Patent N 0. 734,663, dated July 28, 1903.

Application filed February 3, 1903. Serial No. 141,675.

To all whom it may concern.-

Beitknown that I, WILLIAM Bowen, a citizen of the United States, residing at Olney, in the county of Ricbland and State ofIllinois, have invented a new and useful Ointment or Pill Slab; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

a The invention relates to an ointment and pill slab; and it has for its object to provide a simple, inexpensive, and efficient device of this character designed for the rolling of pills and the mixingof theingredients of ointments and the like and adapted to enable pills and ointments to be conveniently compounded and accurately divided.

A further object of the invention is to provide an ointment and pill slab adapted to hold firmly a sheet of transparent paper or other suitable material in position for forming a rolling or mixing surface and capable of permitting such'transparent sheet to be readily removed to enable the same to be destroyed after use, thereby obviating the necessity of performing the disagreeable task of washing and cleaning the slab after use, as is usually necessary to devices of this character.

The invention consists in the novel construction and arrangement of parts hereinafter described and shown, and particularly pointedout in the'claims hereto appended.

In the drawings forming part of this specification and in which like numerals of reference designate corresponding parts, Figure 1 is a perspective view of an ointment and'pill slab constructed in. accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view of one corner of the device.

Referring to the drawings, 1 designates a slab forming thebase of the device and con-' structed of any suitable material+such as wood, porcelain, earthen ware, glass, stone, or

any other hard material susceptible of a smooth upper surface-and the said slab is provided with perforations 2, preferably 10- cated at diametrically opposite corners for What I claim is- (No models the reception of screws or any other suitable fastening device.

The slab is designed to receive a sheet 3, of transparent paper or other suitable material, for forming the rolling or mixing surface, and the said sheet is designed to be removed and destroyed after each operation to obviate the necessity of washing and cleaning the slab.

The removable sheet is detachably clamped on the slab by means of a marginal engaging device 4, preferably consisting of a metallic frame, as illustrated in the accompanying drawings; but an elastic band or any other suitable means may be employed for clamping the paper to the edges of the slab. The

slab may be rectangular, round, oval, or of any other desired form, and it is preferably provided at its upper face with a marginal recess 5 for the reception of the clampingframe to permit the upper faces of the same to lie flush with the upper surface of the paper.

The marginal clampingframe has sides which are L-sbaped in vide horizontal and vertical flanges, the horizontal flanges being arranged in the marginal recesses of the slab. When the slab is square or oblong, the corners 6 are preferably cut awayto cause the corners of the clamping marginal frame to project outward and form grips for enabling the frame to be readily removed and to permit the paper or other material to fold without tearing.

A suitable gage orscale 7is arranged at the upper face of the slab, and this scale, which is visible through the transparent sheet, permits a mass of pill material or the like to be accurately divided, as will be readily understood.

It will be understood that various changes in the form, proportion, and minor details of construction may be made without departing from the spirit of the invention.

1. In a device of the class described, the combination of a slab, a flexible covering an ranged on the slab and being of greater area than the upper face of the same, and a removable marginal clamping-frame L-shaped in cross-section and consisting of upper and lower flanges, the upper flange fitting against 100 cross-section to prorial to fold without tearing and adapted to 10 detachably secure a sheet of material to the slab, substantially as described.

In testimony whereof I have hereto affixed resence of twowitnesses.

the top of the slab and holding the paper against the same, and the lewer flange fitting against the side edges of the slab'and em- I bracing the latter, substantially as described.
