Specification of Letters Patent.
Application led A'pril 25, 1921. Serial No. 464,155.
T 0 1U whom if may concern:
Be it known that I, HENRY L. VENN, a citizen of the United States, and a resident of Oak Park, county of Cook, State of Il linois, have invented an Improvement in Dies and Heads Therefor, of which the following is a specification.
This invention relates to dies and heads therefor, and with regard to certain more specific features, to a die and head for male ing paits of rubber tires.
Among the several objects of the invention may be noted the provision of a simple and effective die and head for use with rubber and similar materials; and the provision of an inexpensive and durable construction of die and associated parts, for making parts of rubber tires.
The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts, which are exemplified in the construction hereinafter described and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings, in which is shown one of various possible embodiments of this invention,
Figure l is an end elevation of a die and head;
Fig. 2 is an elevation of the other end thereof;
Fig. 3 is a longitudinal vertical section of the die and associated parts;
Fig. 4 is an end elevation of the die plates, on an enlarged scale;
'Fig. 5 is a vertical transverse section on the line 5 5 of Fig. 4.; and
Fig. 6 is a face view of the disk.
Similar reference characters indicate corresponding parts throughout the several views of the drawings.
Referring now more particularly to Fig. l of the accompanying drawings, there is illustrated at l the body of a die head, in which is detachably mounted a die member comprising in the present instance two die plates 3,4, which for convenience may be referred to as the upper and lower plates respectively. y
As is indicated in Figs. 3 and 5, these plates are mounted in a horizontal transverse groove 7, in the head member 1. This l groove has preferably a. moderate amount of taper as is shown in Fig. 1, and the plates instance a cylindrical 3, are correspondingly tapered, in order to insure a tight fit between plates and head member when the plates are in operative position. Additional means (not shown) may be. provided if desired, to hold the plates ip position with respect to the head member. Loacting means Asuch as the tongue 9 on the upper plate 3 and the groove 1() on the lower plate 4 prevent displacement of one plate with respect to the other. Or the platesmay be made in a single piece. The head member extends from the flattened end-portion 12 at the groove 7,. to an annular portion 14 at the other end of the member. The latter portion is threaded as at 16 to fit corresponding threads of the apparatus in which it is mounted, in this steamjacketed casing 18, shown in Fig. 3.
The casing is shown conventionally as having an annular space 20 for the reception Patented J une 28, 1921.
of steam for maintaining the 'rubber in l proper condition, and a screw conveyer 22 for forcing the rubber toward and through the die. A disk 24, perforated in two or more placesas indicated at 26 in Fig. 6, is mounted between the annular portion of the head member and the adjacent shoulder in the casing 18, and takes the roll oi twist out of the rubber before the rubber reaches the die plates. A belt conveyer 28 is operated at a proper speed to convey the web 29 away from the die plates as fast as it emerges from said plates.
By having the die plates removable, they maybe readily replaced when it is found desirable to repair or renew, them or to alter the contour of the rubber web that is to be formed in the apparatus. v
As is shown in Figs. 1 and 3, the thickness of theA head member is substantially the same throughout the several portions exposed to the air. To effect this, the. member is formed vwith the concave or depressed surfaces 31 of a contour similar to the contour of the interior surface 33 (Fig. 3) of the head member. This equality of thickness of metal insures equality of temperature throughout the inner surface 33 and equal radiation of heat from the interior to the exterior, throughout the head member. As a result of this construction, excessive temperature within themember is effectively avoided, and premature curing or hardening of the rubber is prevented.
Y combination, a
Fromthe above, it will be seen that the several objects of the invention are realized, and other advantageous results attained.
As various possible embodiments might be made of the above invention and as various changes might be made in the embodi-. ment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
I claim:
1. In apparatus of the class described, in combination, a head member, means for detachably securing a die member thereto, means for securing the head member to a casing containing a conveyer, and means for equalizing the heat radiation in the head member.
2. In apparatus of the class described, in
head member of substantially uniform thickness throughout the portions thereof eXposed to the air, and a die member detachably secured to the flattened end of said head member.
3. In apparatus of the class described, in combination, a housing, a conveyer therein for forcing material toward the end of the housing, a head member threaded in said end, and a die member detachably secured in said head member and adapted to form the material passing therethrough, into a strip or Web of the desired contour, the head member being of .substantially uniform thickness throughout.
4. In apparatus of the class described, in combination, a head member` of substantially uniform heat-radiatingcharacteristic, and die plates detachably secured to onel end of said member.
5. In apparatus of the class described, in
tachably secured in said flattened end of the v first member and adapted'to formthe lmaterial passing therethrough, into a strip or web of the desired contour, and a conveyer for removing the Web from the first member` as the web emerges therefrom, the first member being of substantially uniform thickness throughout, to equalize radiation of heat and to prevent premature curing of the` material therein.
. 6. In apparatus of the class described, in combination, a j acketed housing, a conveyer therein for forcing material toward the end of the housing, a head member having an annular portion threaded in said end and terminating ina fiattened portion, coperating die plates detachably secured together against relative movement and detachably secured in a transverse groove in said flat-` tened portion and adapted to form the material passing' therethrough, into a strip or web of the desired contour, an Yapertured disk mounted between the conveyerl and said member and adapted to eliminate the roll or -tvvist of the material fed to the member,
and a conveyer for removing the Web from the member as the Web emerges therefrom, the member being of substantially `uniform thickness throughout, to equalize radiation of heat and to prevent Vpremature curing of the material therein.
In testimony whereof, I have signed my name to this specification this 19th day of April, 1921.
. HENRY L. VENN.
