Description
JOHN M. LARSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO NATIONAL REGULATOR COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
REGULATING DEVICE.
application filed June -15, 1923. Serial No. 645,620.
To all whom it may concern."
lie it known that I, JOHN M. LARSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Regulating 'Devices, of which the following is a full, clear, concise, and exact description, reterence being had to the accompanying drawing, forming a part of this specification.
My invention relates to a regulating d evice, and more specifically it relates to a diaphragm-cell-actuator.
One of the objects ot'my invention is to provide a. diaphragin-cell-actuator in which the individual cells are constructed as independent units, unconnected and noncommunicating with respect to each other and readily removable from the stack.
This construction has two distinct advantages: (1) If a cell is damaged it can be a readily removed and repaired or replaced by ill ire
a new cell without disturbing the other cells in the stack; (2) injury to a. single cell does not affect the operativeness oil the other cells, as is the case where thecells are incommunication with each other. It has another advantage also in that the diaphragms are flexible throughout their entire extent, as is not the case when the cells are connected together.
A further object ot my invention is to provide improved. means whereby the entire stack of cells may be easily and quickly removed from the well "tor the purposes of repairing, testing, etc. Further objects will follow from the description andthe appended claims. a
In the drawings in which an embodiment of my invention is shown- Figure 1 is an axial sectional view snowing the diaphragm cage and well; Fig. 2 is an enlarged axial view through the stack of diaphragm cells; and, r
Fig. 3 is a section on the line 3-3 of Fig.
2 showing how the individual cells are removed.
Referring now to the drawingsin detail the construction shown therein comprises a stack of superposed, unconnected, non-- communicating diaphragm cells 10, a cage 11 containing the diaphragm cells to facilitate handling them collectively, a casing or well 1.2 in which the cage and cells are containcd, a plunger head 13 engaged by the uppermost diaphragm cell and actuated by the stack of cells, alever 14C actuated by the plunger head, and a bonnet or cap 15 on the casing 12, through which the plunger rod 16 extends and on which the lever is pivotally mounted at 17.
One of the uses of such an actuator might be to control the damper of a heating plant,
the well 12 being screwed into the wall 18ot the boiler, so that the inner portion of the well would be exposed to the temperature within the boiler whereby the diaphragm cells 10 would be affected by the boiler temperature. There are of course many other locations where such a construction could be used.
As shown in detail in Fig. 2, the individual diaphragm cells are unconnected and non-communicating with respect to each other so that one ot the cells may be readily removed from the stack without removing theothers for testing, repairing, etc.
As shown in Fig. 3, the bars 18 of the cage 11, may be sprung outwardly, as indicated in dotted line on Fig. 3, to permit the removal of the cells 10.
a In order to center the cells with respect to each other and maintain them in align- Fill merit, they are provided with interengaging depressions and projections, the projections. v
therein a rovided with a countersunk 1 ormed by pressingthe sheet lid walls of the opening and the thickness of the solder plug which results from this countersinking.
'lh'e cagell in which the diaphragmcells were contained not only serves as a convenient .meanstorhandling the cells collectively but also serves toprevent injury to the cells h over-expansion. Thus no matter what 1: e rise in temperature, the cells can not expand befilltl a certain point,that is the po nt 'atw ltlll ch the plunger head 13 cugages the annular head 22 of the upper end and lift the cage 11 out of the Well.
of the cage. This prevents the expansion of the individual cells beyond a certain limit.
In order to, lessen the strain on the rivets 23 which secure the cage bars 18 to the cage-head 22, I so locate these rivets that they will be engaged by the plunger head 13, at the limit of its upper movement, thereby relieving the tensile strain on these rivets.
If it is desired to get to the diaphragm cells for inspection or repair, all that is necessary to do is to take oil the bonnetn115 e individual cells can then be removed from the cage laterally, as indicated in Fig. 3.
The stem 16 and bonnet 15 may be used as a sort of handle for withdrawing the cage 11 from the casing 12.
It will be seen that I have thus provided. a diaphragm-cell-construction in which the individual cells may be readily removed and repaired or replaced Without disturbing the other cells in the stack; in which the diaphragm cell is flexible throughout its entire extent; in Whichthe unconnected cells are maintained in alignment with each other, and in which the entire stack of cells can be readily handled collectively.
-W-hi1e I have shown but one form of my invention, it is obvious that it may be embodied in. other forms covered and defined by the claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. A heat controlled actuating device comprising a cage and aplurality of superposed, unconnected non-communicating expansible cells in said cage, said cage comprising a plurality of longitudinally extending spring bars embracing said cells and yieldable laterally to permit the removal of the cells from said cage.
2. A heat controlled actuating device comprising a cage, a plurality of superposed, un-
connected, non-communicating expansible cells in said cage, and a plunger head actuated by said cells, said cage comp-rising a plurality of longitudinally extending bars, embracing said cells, and a ring to which the ends of said bars are riveted, the ends of the bars being bent inwardly and the heads of the rivets being engageable by said plunger head to relieve the tension on the rivets when the cells are expanded to the capacity of the cage.
3. Aheat controlled actuating device comrisin a casin a ca e in said casin readil I D D O removable therefrom, a plurality of superposed unconnected expansible cells in said cage readily removable therefrom, and a plunger head in said cage actuated by said cells but disconnected therefrom, and provided with an actuating stem extending from said casing, whereby said actuating stem may be used to withdraw the cage from the casing.
4. jA heat controlled actuating device comprising a stack of superposed unconnected, noncommunicating expansible cells, the walls of said cells being of thin flexible sheet metal to permit expansion and contraction of the cells, said thin flexible sheet metal JOHN M. LARSON.
