DUST-RETAINING DEVICE FOR CAN-FILLING MACHINES.
Application filed December 23, 1918.
To all whom it may concern:
Be it known that I, CHnsnEY T. SMALL, a citizen of the United States of America, residing at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and useful Dust-Retaining Device for Can-Filling Machines, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to a dust retaining device for can filling machine; and is more particularly adapted for use in connection with a machine, such as shown in my prior application Serial No. 184,990 filed August 8, 1917, in which a nozzle enters the can during the operation of filling and performs not only the function of a nozzle but also of a displacing member. My invention may, however, be usedin connection with other forms of can filling machines.
In the accompanying drawing which illustrates one form of device made in accordance with my invention, together with a portion of the filling machine to which the same is applied, Fig. 1 is a sideview partly in section, Fig. 2 is a view similar to Fig.1,
but showing the can into which the nozzle projects, Fig. 3 is a sectional view showing a different form of can and also showing a filling member or position in the nozzle, and Fig. 4 is a top plan view of the nozzle and filling member detached from the other parts.
5 represents a nozzle carrying member which is like that shown in my prior application above referred to. Secured in an opening 6 in the said member 5 by means of a reduced upper part 7 provided with threads is a nozzle 8. The outer wall of the nozzle is straight below the reduced portion 7 while the inner wall is slightly tapered as best shown in Fig. 3 so that the internal area of the nozzle is greater at its lower end, in order to facilitate the discharge of the contents of the nozzle into the can or other receptacle to be filled. In the drawings, I have shown the nozzle as cylindrical in form.
Serial No. 268,031.
The lower end of the nozzle is provided with an outwardly projecting flange 9 and the nozzle is surrounded by a dust retaining member 10 the central portion of which is spaced a slight distance from the outer wall of the nozzle 8. This dust retaining member 10 is provided with an inturned lower edge lladapted to fit snugly around the nozzle 8 and make dust tight contact therewith. The upper edge 12 of the member 10 is flared outwardly so as to provide a contact surface for engagement with the upper edge of the can and also to make contact with the lower face of the nozzle carrying member 5. Surrounding the nozzle 8 isa coil spring 14: bearing at one end upon the inturned lower edge 11 of the member 10 and at the other against the lower face of the member 5. The object of this spring 14; is to normally hold the member 10 against the flange 9 as shown in Figs. 1 and 3 of the drawings.
When the member 10 is forced upwardly by I the can 15 as shown in Fig. 2, this spring 14 lies in the space between the nozzle 8 and the body of the dust retaining member 10, as shown in said Fig. 2. The can 15 shown in Fig. 2 is provided at its upper end with an inturned edge 16 while the form of can 15''? shown in F ig. 3 is provided with an out turned upper edge 17 In either case, or in case the upper edge is straight without any turned over portion, the upper edge of the can contacts with the flared edge 12 of the member 10, preferably at a point near to the junction of this outwardly flared portion with the body of the member. The nozzle carrying member 5 preferably has secured to it a wear plate 18 which over laps the upper edge of the nozzle 8.
