Claims. 1

This invention relates to new and useful improvements in a device for feeding pulverized or granulated material and proposes certain improvements in the construction shown in my earlier application Serial No. 763,367, filed July 24, 1947, now matured into Patent No. 2,568,814, dated September 25, 1951.

More specifically, the present invention proposes the construction of an improved device for feeding pulverized or granulated material and, more specifically, relates to a device for feeding' small quantities of face powder upward within its containing box so that it may be conveniently picked up with a conventional powder puff and applied to the face in the usual manner.

Another object of the present invention proposes characterizing the device by a fiat disc which is adapted to be rotated on the top surface of the pulverized or granulated material; such as face powder, and which is provided with depending scoops arranged in a manner to feed small quantities of the pulverized or granulated material onto the top face of the disc as the disc is given a partial rotation.

Still another object of the present invention proposes forming the center of the disc with'a formation for throwing the pulverized or granulated material laterally to the sides as the disc is rotated for preventing the material from caking beneath the center of the disc and restrain downward movement of the disc.

The invention further proposes providing the top of the disc with a handle by which a grip may be conveniently had on the disc for rotating the same.

A further object of the present invention proposes pivotally mounting the handle on the top face of the disc in a manner so that the handle may be pivoted to an out of the way position extended parallel to the top of the disc.

A still further object of the present invention proposes providing the edge of the disc with a depending knife for severing the top protective cover of paper usually applied to the inside of powder boxes or any box or container having pulverized or granulated material.

Another object of the presentinvention proposes forming the disc of a thin sheet of metallic or plastic material and to provide it about its periphery with a reinforcing means in a manner to stiffen the disc and lessen its chances of becoming misshapen in use.

The present invention also proposes forming the sides or one .side of thescoop with small notches extended into the material of the scoop from the open ends thereof in a manner to impart some resiliency to the scoop to prevent the pulverized or granulated material from becoming stuck in the scoop and to permit some entrance of the pulverized or granulated material into the scoop fromthe side or sides thereof.

It is a further object of this invention to construct a device for feeding pulverized or granulated material which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and Fig, 2 is an enlarged partial side elevationalview of Fig. 1.

elevational' view of Fig. '11 is a perspective. view of one of the scoops of the form of the invention shown in Figs. 8 to 10, looking at the side of the scoop facing toward the center of the device. l

The device for feeding pulverized or granulated material, according to the form of the invention shown in Figs. 1 to 6, includes a flat disc 20. The

disc 20 is preferably circular inplan and is formed of a thin sheet of metallic or'plastic material and is reinforced by a downwardly depressed circular rib 2| formed in the disc adjacent the periphery thereof. The rib 2| stiffens the disc 29 and prevents it from becoming misshapen in use.

While the disc is illustrated on the drawing as being reinforced by a downwardly pressed rib 2!, this is by way of illustration only, as the rib could be upwardly pressed or the disc could be reinforced by bending the periphery of the disc into a depending flange, by forming the disc with a roller edge or by bending the periphery of the disc under.

A handle 22 is provided which forms a convenient grip by which the disc 20 can be rotated. The handle is formed of an elongated strip of metallic or plastic material and has its ends pivotally secured to lugs 23 by pivot pins 24. The lugs 23 are stamped from the material of the disc 23, Within the circular rib 2|, and are bent to extend vertically therefrom.

The center of the disc 20 is formed with a downwardly pressed formation 25 which is to engage the pulverized or granulated material beneath the center of the disc 20 and continuously feed the material outward as the disc is rotated. This action will prevent the material from caking beneath the center of the disc 26 where it will interfere with the downward movement of the disc with relation to the material.

On the drawing, the formation 25 is .shown.

in the shape of a four-pointed star, but this is by way of illustration only, as the formation may take any shape which will effectively feed the material outward from beneath the center of the disc.

A plurality of scoops 25 are pressed from the material of the disc 20 and those scoops have their open ends faced in the direction in which the disc 20 is to be rotated so as to feed the pulverized or granulated material upward onto the top face of the disc 26. The direction of rotation of the disc 20 is illustrated by the arrow A in Fig. I. From Fig. 1 it will be noted that the scoops 26 are arranged in concentric circles with the scoops of each outermost circle larger than the scoops 28 of each adjacent innermost circle. As the scoops 26 of the outermost circles must operate over a greater surface of the pulverized or granulated material, forming those scoops of a larger size will serve to feed the material of the top surface evenly upward through the disc 20 so as to keep the top surface of the pulverized or granulated material fiat at all times with an even distribution.

As shown in Figs. 2 to 5, the side walls of the scoops 26 are formed with small triangular notches 126 extended inwards from the open ends of the scoops 26. The notches Z6 render the scoops 26 somewhat resilient preventing the pulverized or granulated material from becoming jammed in the scoops and also permitting the pulverized or granulated material to enter the scoops 26 from the sides thereof through the notches 26 The notches 26 further provide for ventilation of the top surface of the pulverized or granulated material by providing openings for the circulation of greater amounts of air between the bottom face of the disc 20 and the top surface of the granulated material.

One side of the disc 20 is formed at the peripheral edge thereof with a depended knife member 21, see Figs. 1 and 6, for the purpose of severing the sheet of paper which usually covers the pulverized powder box or the top of the pulverizer or granulated material in a similar container.

After the knife member 2! has been used for its intended purpose it may be bent under to extend parallel to the bottom face of the disc 20. In this position, the knife member 2'! will not interfere with the operation of the scoops 25 in lifting the pulverized or granulated material from the very bottom of the box or container. I

The operation of thisfirst form of the invention is as follows:

While the device of the present invention has general application for feeding pulverized or granulated material it is designed chiefly for feeding pulverized face powder upward within a powder box, and in Fig. 6 the device is shown applied to such a powder box 28. Normally, such boxes are covered by a cover, not shown on the drawing. The box 28 contains pulverized face powder 29 and is enclosed within the box 28, when purchased, by a piece of paper 39 fixedly secured in position slightly below. the top of the box forming a chamber 31, above the piece of paper 30, in which a powder puff (not shown) is usually placed.

In Fig. 6, the device ofthe present invention is shown rested on the top facev ofthe piece of paper 38 with its knife member 2.! piercing the piece of paper 38 at one side thereof. The

handle 22 is extended vertically and may be used.

to give the device one complete revolution so that the knife member Zl'will completely sever the piece of paper 30 from the, interior'ofthe' box. The device is then liftedout of the box and the piece of paper 30 removedand discarded.

The knife member 21 having'served. its pur-' pose, is now bent out of the wayv beneath the disc 20 to extend parallel to the: bottom face of the disc. Then, the device is returned to the box to rest on the top surface of the pulverized.

face powder 29.

With the handle 22 extended vertically, the

some of the pulverized powder fr'om' the top face of the disc 20.

In the modification of the invention shown in Fig. '7, the construction of the device for-feeding the pulverized or granulatedmaterial-is similar I to that previously described, except that the scoops 26' are formed in-the disc 20 so that they extend at an angle to the direction of ro tation of the disc 20', whichis illustrated in Fig. '7 by the arrow B.

On the drawing, Fig. 7 illustrates the scoops 26 as being extended at an'angle of approximately 45 degrees to the direction of rotation of the disc 20', but this angle may beivaried in accordance with the particular requirements-of the pulverized or granulated material to be fed upward through the scoops ofthedevice.

In other respects, this form of the invention is similar to the previous form and like refere ncenumerals identify like parts in each ofthe several views. v

formed of a thinsheet of sheet metal which has its edge portion reinforced by a downwardly bent narrow flange 4i.

The top of the disc MI is provided with a handle 42 by which the disc 46 can be rotated. The handle l2 is formed of a length of wire bent into an inverted U-shape and whichhas its ends bent into laterally inwardly extendirigtrunnions 43. The trunnions 43 are rotatively received'in complementary bosses A l stamped from the material of the disc 48. The engagement of the trunnions 43 with the bosses 44 permits the handle 42 to be pivoted between a position extended vertically upwards from the top face of the disc 18 and a position flat against the top face of the disc M on either side of the bosses M.

The center of the disc 30 is formed with a four-pointed star formation 45, see Fig. 8, for the purpose of feeding the pulverized or granulated material outwards so as to prevent it from caking beneath the center of the disc 40.

A plurality of scoops G6 are stamped from the material of the disc 40 and are arranged in spiral lines extending from the periphery of the disc lfi toward the center thereof, with the scoops being progressively smaller toward the center of the disc. The open sides of the scoops 46 are extended substantially in the direction of rotation of the disc 43 which is illustrated in Fig. 8 by the arrow C.

The sides of the scoops 46 faced in the direction of rotation of the disc 40 are formed with notches 46 see Fig. 11, extended inward from the open sides of the scoops. The notches 46 render the scoops somewhat resilient and permit the pulverized or granulated material to be fed into the scoops through the notches 46 in addition to the open ends thereof, as the disc it is rotated in the direction of the arrow C.

One side of the reinforcing flange M of the disc t?! is formed with a depending knife member 4? for cutting the piece of paper normally positioned across the top of a powder box over the contained pulverized face powder as described in connection with the first form of the invention illustrated in Figs. 1 to 6.

It is believed that the operation of the form of the invention shown in Figs. 8 to will be apparent from the operation described in connection with Figs. 1 to 6 and that a further explanation will be unnecessary.

While the arrangements of the scoops shown in Figs. 1, 7 and 8 are well adapted to the feeding of pulverized or granulated material, the arrangement of the scoops shown in Fig. 8 is also well adapted to scraping powder from solid cakes of such powder. This is so, as the spiral arrangement of the scoops 46 will be effective over the entire top face of the cake of powder and prevent the device from merely cutting ridges in the top face thereof.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
