MEASURING-CAN.

SPECIFICATION forming part of Letters Patent No. 623,499, dated April 18, 1899.

Application filed August 19,1898. Serial No- 688,990. (No model.)

To all whom it may concern:

Be it known that I, Gnonon W. CHANDLER, a citizen of the United States, residing at Manhattan, in the county of Riley and State of Kansas, have invented new and useful Improvements in Measuring-Cans, of which the following is a specification.

My invention relates to measuring vessels, and contemplates the provision of a can equipped with means wherebya certain predetermined quantity of its contents may be quickly and easily discharged whenever desired without the necessity of removing its top, the said meansbeing very simple and adding but little to the cost of the can and being adapted to be entirely contained in the can at the time of packing, so as not to offer any obstruction which would increase the space taken up by the can in a box or packing-case.

IVith the foregoing in view the invention will be fully understood from the following description and claims when taken in conj unction with the annexed drawings, in which Figure 1 is a diametrical section of a can embodying my improvements, all partsof which are shown in their proper operative positions. Fig. 2 is a similarview showing the positions which the parts of the improvements are caused to assume at the time the can is packed. Fig. 3 is an enlarged transverse section taken in the plane indicated by the line 3 3 of Fig. 1.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which A is the body of a can, which is similar to those usually employed for containing bakingpowder, except that it is provided with an opening a in its bottom and an upwardly-directed cylinder or cylindrical wall 1), surrounding the same. B is the can-coveigwhich is also of the ordinary construction, with the exception that ,it has an aperture 0 coincident with but smaller than the opening a.

O is a guide fixedly connected to the side wall of the can-body and disposed above the opening a in the bottom thereof, and D is a rod movable in the guide 0 and through the opening a in the can-top. Said rod is threaded at its lower and upper ends and at an intermediate point of its length, as indicated by (Z, c, and f, respectively, and is equipped with two pistons E F of a diameter to snugly fit the cylinder. The pistons may be of any construction suitable to the purposes of my invention; but I prefer to have them respectively comprise two metallic disks g, a packing or gasket h, of cork or other suitable material, interposed between and extending slightly beyond the perimeters of the disks, and nuts 2 arranged above and below the said disks, the nuts of the piston E engaging the threads (I of the rod and the nuts of the piston F engaging the threads f, and both sets of nuts having for their purpose to clamp the disks against the packing or gaskets h to securely hold the same on the rod. The pistons are arranged on the rod D at a suitable distance apart, according to the quantity of powder or other substance contained in the can which it is desired to discharge at each depression or downward movement of the rod, such quantity being increased by moving the pistons apart and diminished by moving the pistons toward each other. Thus it will be seen that with the can filled v with baking-powder or other substance and the parts in the position shown in Fig. '1 the space between the pistons E F will be occupied by a certain quantity of powder, which when the rod D is depressed will be carried down into the cylinder 1) and separated from the remainder of the powder in the can by the upper piston F acting as a cut-off. When the rod D is depressed sufficiently to carry the lower piston E out of the cylinder Z), the quantity of power between the two pistons is permitted to freely escape into a receptacle placed to receive it. On the return or upward movement of the rod D as soon as the upper piston F passes out of the cylinderb the space between the two pistons will be occupied by powder, the lower piston serving to prevent the escape of any powder until the piston-rod is depressed after the manner before described. The upward movement of the piston-rod and its appurtenancesis limited by the guide O, which, engaging the upper piston F, prevents the lower piston from moving up out of the cylinder 1), and thereby precludes the casual escape of the powder from the can. I prefer to arrange the pistons such a distance apart that an amount of powder corresponding to a table-spoonful will occupy the space between them and be discharged from the can at each depression of the piston-rod. It is obvious, however, that being mounted in the manner described on the rod the pistons may be fixed at different distances apart, according to the amount which it is desired to discharge at each downward movement of the piston-rod.

G designates what I will for convenience of description term the finger-piece of my improvements. Thisfinger-piece G is preferably of wood and has a bore j extending throughout its length, so as to enable it to receive the rod D. It also has a shoulder 7t and a transverse passage Z intersecting the bore 7', said passage being designed to receive a metallic nut m, which in turn receives the rod D and engages the threads 6 thereof. At the time of packing the can the finger-piece G is reversed on the rod Dthat is to say, is inverted after the manner shown in Fig. 2- so that its lower end bears on the guide 0 and its upper end rests in the opening 0 of the top=and flush with said top. In this position the finger-piece engaging the guide C eifectually prevents casual downward movement of the several parts. Casual upward movement of the parts is prevented by a strip at of paper or other suitable material connected to the top B by adhesive or othersuitable means and resting over the opening 0 therein. This strip serves to prevent casual upward movement of the piece G and the parts connected therewith, seals the opening 0, and is susceptible of use as a label when desirable.

In the position shown in Fig. 2 all of the parts of my improvements are contained entirely in the can and do not therefore increase the space taken up by the can in a box or packing-case, which is a higl'ily-important advantage.

hen it is desired to use the contents of the can, the top B is removed from the body A, and the strip at is disconnected from said top, or an opening is formed in said strip sufficient for the passage of the finger-piece G. Said fin ger-piece is then removed from the rod D and after being passed through the opening 0 in the cover is replaced 011 the rod in the position shown in Fig. 1, when the can and discharging mechanism are ready to be used in the mannerset forth. \Vhen the improvements are so used, the shoulder of the finger-piece is designed to engage the top B, and thereby limit the downward movement of the rod D and prevent the upper piston thereon from being moved below the cylinder 1).

My improvements are applicable to receptacles of various 'kinds and are adapted to measure different kinds of substances, as coffee, sugar, spices, &c. I therefore desire it understood that the term can as herein employed is intended to comprehend receptacles and vessels. I also desire it understood that,

while I prefer to employa finger-piece of wood because of its lightness and cheapness, I may,

if desired, use a metallic piece having interio'r threads, in which event the nut will of course be dispensed with.

Having thus described my invention, what I claim is I 1. The combination of a can-body having a discharge-passage at its lower end, a removable cover on the body having an opening coincident with the discharge-passage, a reciprocatory rod arranged in the can, pistons on said rod conforming in size to the dischargepassage of the can, and a fingeriece resting in the opening in the cover and having a bore receiving the rod and means detachably con necting it to said rod whereby, when not in use, it may be reversed on the rod and be contained entirely in the can, substantially as specified.

2. The combination of a can-body having an opening in its bottom and a wall surrounding the same, a removable cover on the body having an opening, a reciprocatory rod arranged in the can, pistons on said rod, a fin ger-piece resting in the opening in the cover and receiving and detachably connected to the rod whereby when not in use it may be reversed on the rod and be contained entirely in the can, and a removable strip connected to the cover over the opening therein, substantially as specified.

3. The combination of a can-body having an opening in its bottom and a wall surrounding said opening and also having an interior guide, a removable cover arranged on said body and having an opening, a reciprocatory rod extending through the guide and having threads e, pistons arranged at a distance apart on said rod and disposed below the guide, and the finger-piece resting in the opening in the cover and having the bore receiving the rod and the interior threads engaging the threads 6 thereof and also having the shoulder arranged to form a stop, said fingeriece being adapted to be reversed on the rod and contained entirely in the can, substantially as specified.

4c. The combination of a can-body having an opening in its bottom and a wall surrounding said opening and also having an interior guide, a removable cover arranged on said body and having an opening, a reciprocatory rod extending through the guide and having threads e, pistons arranged at a distance apart on said rod and disposed below the guide, the reversible finger-piece having the bore receiving the rod and also having the passage intersecting the bore, and the exterior shoulder 75, and the nut arranged in the passage of the finger-piece and engaging the threads 2 of the rod, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE W. CHANDLER.
