FILLER.

SPECIFICATION forming part of Letters Patent No. 388,249, dated August 21, 1888.

Application filed October 26, 1887. Serial No. 253,481.

To all whom it may concern:

Be it known that I, GEORGE BLUM, a citizen of the United States, residing at Newark, in the county of Essex and State ofNew Jersey, have invented certain new and useful Improvements in Powder-Fillers; and I do hereby 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 appertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference marked thereon, which form a part of this specification.

The purpose of this invention is to provide [5 a device for filling suitably-prepared receptacles with sedlitz or other powders, which is compact in construction and of small size, so

that it may be easily operated by one hand,

and which may be made at very little expense.

Heretofore in preparing sedlitz powders for sale the powder is first measured in cups of the required capacity and the powder deposited in unfolded papers of the required size which are afterward folded by hand. This evidently requires a great deal of handling, and hence occupies much time in preparing the powders for sale, and, moreover, owing to the thickness of the folded paper, a box of considerable size is necessary to hold the required number of powders.

My invention is designed to obviate the extra handling of the powder and the paper, to enable a greater number of powders to be prepared in a given time,and to reduce the size of the package containing the powder, and hence permit the use of a much smaller box for the same number of packages.

In the sheet of drawings herewith accompanying, in which similar letters of reference in- 4: dicate corresponding partsin each ofthe views, Figure l is a side elevation of my improved filler inserted in a powder paper or envelope, showing the position of the parts just before the powder is expelled from the powder-chamber into the envelope. Fig. 2 is a view of an envelope which is used to receive the powder. Fig. 3 is a section taken through m, Fig. 5; and Fig. 4 is a front elevation of my improved filling device. Fig. 6 is a section taken 50 through g on Fig. 5, illustrating the position of the parts when arranged to receive the (No model.)

smaller quantity of powder or tartaric acid designed for the white paper.

In the above views, (L indicates the receptacle havinga powder-chamber, a,within, which 5 receives the powder, said receptacle being preferably sharpened or tapering at the end which is inserted into the powder and also into the powder-envelope to more readily permit the insertion thereof. Extending through the bottom of the receptacle a, and opening into the chamber a, is a perforation through which works a plunger, I), having on the end within the powder-receptacle a head, I), which is of sufficient size to fill said powder-chamber and still permit the same to move reciprocally within the same.

Encircling the receptacle a is a plate, 0, which acts as a guard to prevent the powder into which the receptacle is inserted from adhering to the fingers of the hand which holds the filling device, hooks or finger-pieces (I being formed on or secured to the end of the receptacle back of the guard c, by which the filler is held in the hand. Said hooks may be riveted orotherwise secured to the receptacle, or may be formed or cast integrally therewith, as may be desired; also, the guard may be riveted or otherwise secured around the receptacle. WVhile the use of the said guard is considered advantageous, still the filling device may be conveniently used without said guard, particularly when the receptacle is made of considerable length, or when the fingerpieces or hooks are made to extend back- 8 ward away from the bottom of the receptacle.

As indicated more particularly in Figs. 3 and 6, the plunger 1) is tubular, and is provided with a slot, If, on one side thereof extending from the stop 1) down to or nearly to the head, 0 and within said tubular spindle is arranged a spiral spring, bflone end of which abuts against the finger-piece I) and the "other end projects through the slot b and is preferably wrapped around the outside of the spindle, thus acting 5 to hold the lower end of the spring stationary, so that it will be compressed when the plunger is moved into the powder-chamber, and thereby store up sufficient force to withdraw by its expansion the plunger from the open end of the powder-chamber and restore it to its normal unoperated position, as indicated in Figs. 1 and 3, at the bottom of said powder-chamber.

While I have illustrated and described this peculiar arrangement of the spring within the plunger, I do not wish to be understood as limiting myself to this particular arrangement and construction, as said spring may be otherwise arranged to produce the desired movement of the plunger within the chamber in the receptacle; in fact, I may dispense with the spring altogether and move the plunger in the chamber by hand. As thus constructed, the spring acts to throw the head down into and against the bottom of the powder'chamber, leaving a large space between the said head and the mouth of the chamber, which, when used in preparing sedlitz powders, is of sufficient capacity to hold the quantity of powder designed to fill the blue paper.

In order that the same device may be used to measure the desired quantity of powder to fill the white paper, or that containing the tartaric acid, I have provided a slot, 22, extending from the stop I) along the tube a sufficient distance, which is determined by the length of the space between the head and the end of the powder-chamber. Into said slot b a set-screw, or, projects and limits the movement of the plunger according to the length of the said slot 1). While I have specifically described and illustrated this form and construction of detaining device, I do not wish to limit the scope of the invention thereto.

The operation of the device is as follows: Two of the fingers are inserted through the hooks d and the thumb placed upon the end of the plunger, and the mouth of the filler is inserted and pressed down into the powder and is then lifted therefrom, carrying the contents of the powder-chamber with it. The tapered end of the filler is then inserted into the envelope, and then by the pressure of the thumb upon the plunger the downward movement of the head forces the powder from the chamber into the envelope,which is then sealed up and is finished ready for packing. After a sufficient quantity of the combined soda and salt has been prepared in the blue envelopes the plunger is adjusted to the position indicated in Fig. 6, and the same operation is repeated with the tartaric acid,which is placed in the white envelope.

Having thus described my invention, what I claim is 1. A powder-filling device consisting of a powder-receptacle having finger-hooks thereon,and a guard around said receptacle between the hooks and the end of said receptacle which is inserted into the powder, and a plunger working within said powder-chamber,whereby the powder is expelled from said powder-ch amber, substantially as specified.
