IRdCESSQOF MANUFACTURING LAMINATED VALVES.
Specification of Letters Patent.
Patented May 9, 19.22.
Application filed October 4, 1920. SeriaLNo. 414,450.
To all whom it may concern.
Be it known that I, WILLIAM H. WVAsir BURNE, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Processes of Manufacturing Laminated Valves, and declare the following to be a full, clear, and exaot description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings,
part of this specification.
In Patent No. 1920, I have illustrated a laminated valve built up out of thin washer-like discs of hard steel clamped between top and bottom holding plates and secured upon the end of a valve stem. The fastening together of the parts of the valve head and the union thereof with the stem is most conveniently secured by passing the valve stem through registering holes in the laminae and the clamping plates, and riveting the stem over. I have found that sometimes in valves made the laminae are not clamped to gether tightly enough to secure the full advantage of a perfectly made construction of the type disclosed in my aforesaid patent.
The object of the present invention is to produce a simple and novel method of build- 1ng valves of the aforesaid type, in such a Wa that they will present the compactness an apparent rigidity at the periphery which is so desirable in such valves.
The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my inventionand of its objects and advantages, reference may be had to the following detailed description taken in connection drawing, wherein:
Figure 1 is a view partly in section and partly in elevation through a set of dies in which are assembled the elements to form a single valve, the dies being open;
Fig. 2 is a view similar to Fig. 1, the upper die member being also shown in section, and the dies being partly closed on the work;
Fi 3 is a view similar to Fig. 2, showing the ice fully closed on the work; and
Fig. 4 is a side elevation of one of the completed valves.
1,338,759 granted May 4,
Referring to the drawing, 1 represents a. lower die member in which is held a valve stem, 2, having thereon an annular shoulder, 3, located at some distance below the extreme upper end of the stem; the top of the shoulder being flush with the upper surface of the lower die member. 011 the neck. 4, of the valve stem, that is the part that extends upwardly from the shoulder, while the neck is hot, are. placed in the order named the lower follower or clamping plate, 5, the series of washer-like discs, top clamping plate or follower, 7
The upper die member, 8, carries a central riveting head, 9, which, when the dies are closed upon each other, forges the pro-' jecting part of the neck 4 into a rivet head as indicated at 10 in Figs. 3 and 4. Surrounding the member 9 is a collar, 11, vertically slidable thereon; the collar being provided with an annular flange, 12, through which pass loosely a plurality of bolts, 13, the upper ends of which are screwed into the upper die member; the bolts being long enough to permit the collar normally to project considerably below the lower end of the riveting head, 9. Between the flange on the collar and the overlying portion of the up per die are a series of strong compression springs, 14, which are put under an initial compression when the parts of the machine are assembled.
The parts are so proportioned that when the upper die member is brought down, the yieldable collar engages with the upper follower or clamping plate, 7, before the riveting head comes in contact with the part a of the valve stem which is to be riveted. Then, as the upper die member is lowered still farther, the group of washer-like )arts of which the valve is to be formecl are pressed firmly together throughout a narrow marginal zone, the collar thereafter yielding and causing the springs to be further compressed. Not until after the parts of the valve have been firmly clamped together along the margin does the riveting head begin its riveting operation or, at any rate, the riveting operation should not have progressed very far before the clamping of the valve parts between the lower die and the yieldable collar has taken place. This intermediate condition is illustrated in Fig. 2 while in Fig. 3 the dies are shown complete- 1y closed, the riveting over of the projecting 6, and the I end of the valve stem having been comtween clamping plates applying pressure pleted. I to said plates in the vicinity of their mar- The top and bottom clamping plates out gins to press the laminae firmly together,
