SPEGIFXGATION formingpart of Letters Patent No. 634,837, dated October 10, 1899. Application filed in 20,1899. SerialNo, 717,585. mom-can:

To all whom zit-may concern: I

Be it known that I, FRED L. SEELY, a citizen of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented new and useful Improvements in Apparatus for Measuring, Delivering, and W'rapping Powders, of which the following is a specification.

My invention is designed for the production of an apparatus for measuring, delivering, and wrapping medicinal compounds in pulverized or granulated form, the object of the same being to simplify and otherwise improve the construct-ion of devices of this kind by means of which greater accuracy of measurement and speed of operation may be obtained and whereby the powder or granulated material may be conveniently wrapped in packages of uniform size and shape.

The invention consists of a bed-plate, a re-' ciprocating measurer mounted thereoma hopper, connections between the hopper andthe measurer, and means for holding the parts against which the measurer bears in contact with each other.

The invention also consists in an improved form of wrapping-plate which is adapted to be used in connection with the foregoing parts.

The invention also consists in certain details of construction, combinations of parts, and arrangements of instrumentalities which will be hereinafter more fully described and claimed.

In the drawings forming part of the specification, Figure 1 is a perspective view of the device complete. Fig. 2 is a sectional elevation showing the measuring-plate in its nor- Fig. 3 is a similar view showing the measuring-plate in its dumping or delivering position. Fig. 4 is a detail view of the wrapping-plate, showing one of the paers partially folded thereon. Fig. 5 is an end view of the same, showing-one of the pa- Like reference-numerals indicate like parts in the difierent views. 7 a

The illustration in the'drawings represents one embodiment of my invention, shows the essential features thereof, and serves to indicate how the invention may be carriedout. I do not care to be limited, however, to the a slot 4, as shown.

exact construction and arrangement of parts, as of course these may be varied indefinitely within ,the scope of the protection prayed.

The operative parts of the device are mounted upon a base 1, as shown, thesame being provided with an opening2 at one point there- -in.. The bed-plate 3 is conveniently formed of a strip of metal bent to form two horizontal portions, the lower of which is screwed or otherwise secured to the base 1 and the upper of which constitutes the bed-plate proper.

The connecting-web between the two horizontal portions referred to is provided with The bed-plate proper is imperforate and has secured to the side edges thereof guide-strips 5 5, which project above the upper surface of said plate and form a rectilinear guideway for a rectilinearly-reciprocating measurer 6. The said measurer, as shown, is made of an oblong plate having an opening 7 extending thereth rough at one point .and provided with laterally-extending stop- ,pins 8, which arev adapted to engage the forward ends of the guide-strips 5 for the purpose of limiting the inward movement of said reciprocating measurer.

At the rear end of the plate 6 are laterally-extending hooks or projections 9 9, each connected at its outer end to a coil-spring 10, which is attached at its lower end to the base 1, the said spring serving to hold the plate 6 at all times in close contact with the upper surface of the secured to the base 1 and provided with a 'ring or eye 12 at its forward end, is a funnel- ;forated block 16, normally held in close conbed-plate 3. Supported upon a bracket 11,

tact with the upper surface of the plate 6 by means of springs 17 17, secured to the guidestrips 5 at one end and bearing upon the upper surface of said block at the other end. When the plate 6 is in its normal rearward position, its forward end lies flush with the forward end of the bed-plate 3 and the opening 7 therein registers with the opening in the block 16, from which the nipple 15 thereon leads. I

18 19 represent a toggle-lever, the upright 21, which passes through the slot t in the bedplate 3, around a guide-pulley 22 on the base 1, andthrough the opening 2 in said base,the

lower end of said strap or cord being connected to a treadle. 23, by means of which said toggle-lever and the parts connected therewith may be operated by foot-power.

Secured to the base 1 beneath the forward end of the bed-plate 3 isa wrapping-plate 24, which extends forwardly some distance beyond said bed-plate. The wrapping-plate 24;

is formed with a flat uppersurfaceand a con vexor rounded lower surface, the sides and end of said plate being beveled down to sharp edges.

- In using. the device I proceed as follows, it

being understood of course that the hopper- 13 is supplied with powdered or granulated material andthat the plate 6, which constitutes the measure-r, isin its normal rearward position with the opening 7 therein directly beneath the opening in the block 16, with which said hopper communicates. The opening 7 is made of such size as to hold the exact quantity of material which is to be wrapped up. The treadle 23 being now depressed the toggledever is moved forwardly against the action of the spring ZOandcarries with it the plate 6 until the opening 7 therein projects beyond the forward end of the bed-plate 3. The powder in the opening 7 being now without support drops down upon the wrappingplate 24, and upon releasing the treadle 23 the parts return to their normal positions, and another charge is received in the opening 7. As the plate 6 is held at all times in close contact with the bed-plate 3 by the springs 10 and as the block 16 is held in close contact at all times with the plate 6 by the springs 17, it will be obvious that leakage of material between said plates and block is effectually avoided, so that at each operation of the treadle 23 an exact predetermined quantity of the material will be delivered upon the wrapping-plate 24:. Previous to this delivery of material upon the Wrapping-plate, however, there is inserted paper of proper size, in which the material is to be wrapped. This is laid loosely on the upper surface of said wrapping-plate, and the measured material is delivered thereto. The same is then folded longitudinally in the usual manner, and the ends thereof are bent down upon the under side of the plate 24:, the side edges of said plates serving as guides, whereby the packages may be made of the same size at all times, and for producing a 'crease therein. The under side of the plate is made rounded, and the forward end thereof is beveled for the purpose of enablingv the folded package to be readily slipped off from the plate 24 at its front end.

By the construction described it will be seen that sedlitz or other powders may be'accurately measured in predetermined quantities fed upon the papers in which they are to be wrapped and the papers themselves folded up into equal sizes and shapes.

Having now described my invention, what Iclaimasne'w, and desire to secure by Letters Patent, is
