CHARLES INI. LUNGREN, OF BAYONNE, NEW JERSEY, ASSIGNOR TO THE SAFETY CAR HEATING & LIGHTING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
MEANS OF SUSPENDING INCANDESCENT-LANIP NIANTLES.
Specification of Letters Patent.
Patented Nov. '7, 1905 Application filed August 12, 1904. Serial Nol 220,473.
To all whom, it may concern:
Be it known that I, CHARLES MARSHALL LUNGREN, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Means of Suspending Incandescent-Lamp Mantles, ofwhich the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to means of suspending incandescent-lamp mantles. l
Certain broad features herein shown and described are shown, described, and claimed in a companion application, filed of even date herewith, and are accordingly not claimed herein.
One of the objects of this invention is to provide a simple and eflicient means for suspending fragile articles of the above type in such manner that they may be readily secured in position or removed foireplacing the mantle.
Another object is to provide a resilient suspension adapted to engage the flame-nozzle of the burner without appreciable injury.
Other objects will be in part obvious and in part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the devices herein described and the scope of the application of which will be indicated in the following claims.
In the accompanying drawings, wherein are shown several of various possible embodiments of my invention, Figure I is a sectional elevation of mantle-suspending means with the mantle attached in position. Fig. 2 is a sectional View of a portion thereof, taken substantially on line fr of Fig. l. Fig. 3 is a sectional elevation of an embodiment provided with a different type of securing means. Fig. 4 is a cross-section taken on line y y of Fig. 3. Fig. 5 is a sectional view showing a dame-nozzle upon the member to which the mantle is directly secured. Fig. 6 is a similar view showing integral threads upon the supporting member. Fig. 7 is a similar View of another modification.
Similar reference characters referto similar parts throughout the several views.
It may here be noted that although gasburners utilizing an incandescent mantle have marked advantages in the matter of quality and quantity of light to be given they are nevertheless open to serious objection on account of their fragile nature and tendency to frequent breaking in use. Another obstacle to be overcome in constructions of this type is the diiiiculty with which the parts bearing the mantle are removed from the supporting means if a tight joint is to be formed between the same.
The above and other defects are remedied in constructions of the nature of that herein described.
Referring now to Fig. l, a supporting member, which may be mounted in any desired manner and to which gas is conducted by any desired means, is represented at l. In this embodiment member l forms the conduit through Which the gas is conveyed to the burner; but it is to be understood that the mantle suspending means, hereinafter described, are useful in other relations. Supporting member l may be formed of-any desired material and, if of metal, has turned upon the lower portion thereof a thread for a purpose hereinafter described. In this embodiment, however, it is preferred that the supporting member be of porcelain, steatite, or similar material and that the thread 2 be formed upon a separate sleeve or ring of metal 3, which is secured in place upon su pporting member 1 between shoulders 4in any desired manner. The thread herein shown, which is of the preferred form, has a fiat upper face lying at substantially right angles with the axis of the supporting member: The lower face, however, is inclined so as to provide a sharp upper edge. This thread is preferably cross-cut, so as to form teeth 5, which are preferably of the shape shown in Fig. 2. These teeth may be made in any desired manner; but it has been found convenient to form the same by means of a longitudinal cut with a milling-machine, thus forming the teeth in vertical alinement, as appears in Fig. 1. It will be seen by reference to the drawings that these teeth will permit a ready rotation of the parts engaging the same in one direction, butl will tend to resist any relative movement in the opposite direction. This toothed thread may be cut in various forms, and the expression toothed as used IOC- throughout this description and in the follow ing claims is meant to comprehend any irregularity of outline tending to resist a relative rotary movement of the thread and the parts with which it engages. Mounted upon a spool or ring 6 is a mantle 7 of any desired form,which is preferably secured in place by means of an asbestos cord, hemmed within one end thereof, within a recess formed by shoulder 8. Spool 6 is lined with a resilient suspending means 9, which is preferably formed of a refractory fibrous material, as
asbestos wicking, so as to be adapted to resist the high temperature to which it is eX- posed and form a tight-and resilient means of suspension for theA mantle. Although other material may be used in place of asbestos, it has been found that this material is peculiarly adapted for the purpose in question, as it performs its functions of cushioning the jar or vibration of supporting member 1 without moving the mantle to any appreciable degree, and hence avoiding the undesirable feature of a moving source of light. Asbestos is also desirable, because aside from the advantageous features above indicated it also possesses by virtue of its fibrous character the quality of forming a tight packing, and thus overcoming any tendency of the gas to leak between supporting member 1 and the spool 6. Packing' 9 may be held within spool 6 by means of water-glass or any otherdesired cement 10; but this spool is preferably provided with an inwardly-turned 'liange 11 in order more positively to hold the packing in place. Support 1 projects downwardly through spool 6 in such manner as to direct the liame caused by the burning of the gas against the mantle 7. By reason of this feature the lower part of supporting member 1 is termed throughout this description and in the following claimsa liame-nozzle, and by such term is meant any member adapted to discharge gas or other material in such position as to be efficiently burned at the point of discharge.
rl`he manner of assembling the parts of the above-described embodiment of my invention is as follows: The mantle 7 having been secured upon spool 6 and the wicking 9 being held within the same in any desired manner, the mantle-supporting spool, with the associated parts, is screwed upon the threaded lower end of supporting' member 1, so as to cause the threads to firmly take into the asbestos packing and form a tight and yet resilient joint with the ring. As above noted, the teeth 5 will permit the packing readily to pass the same when turned in the direction in which the parts are assembled; but if it is attempted to separate the same the sharp rear faces of the teeth will engage the packing and tend to resist such movement.
With the parts in the assembled form, as above described, it will readily be seen that any jar or vibration of supporting member 1 is cushioned by means of packing 9, so as to transmit the same to mantle 7 in such manner as substantially to do away with the harmful effects thereof. Sufficient clearance is of course provided between the supporting' member 1 and spool 6 to obviate all chance of direct mechanical contact between these parts.
It will thus be seen that I have provided a means of suspension for lamp-mantles and other fragile objects which are subject to injury through vibration orjarring of the structure in vwhich they are mounted, which is simple and efficient, and comprises few and easilyassembled parts. The construction is such as to form a tight joint and prevent leakage of gas and yet to permit the ready removal of the lamp-mantle and the member to which it is immediately secured withoutdetriment to the resilient suspending means or any other part of the device. It will also be seen that the device may be used in connection with lighting systems now in use without the necessity for extensive alterations in the same, the change beingl made inthe burner only and the form of chandelier or other secondary suspending device not being affected.
In Fig. 3 is shown another embodiment of my invention which is similar to that above described and differs from the same mainly in the form of retaining means upon the supporting member' 12. As in the former embodiment, the supporting member is provided with integral shoulders 13, between which is secured a metallic ring 14 in any desired manner. This ring is provided upon its outer surface with a thread 15, which is of the ordinary type, but is cut so as to form teeth 16, as shown in Fig. a of the drawings. The method of assembling the several parts and the operation of the same when assembled are substantially the same as in the above-described embodiment, the teeth 16 tending to resist movement in either direction. If it be desired to form the supporting member of metal with this form of thread, it is preferred to use a construction such as is shown in Fig. 6. ln this form the spool 17, with the'parts immediately associated therewith, is substantially the same as in the last-described embodiment, but the supporting' member 18 is provided with a thread 19 cut thereon instead of upon a separate member. The means of assembling and operation of this device is substantially the same as that above described.
1n Fig. is shown another embodiment in which the supporting member 2O is of such dimensions as to take into the wicking 21, substantially as above described, but not to project entirely through the spool 22. The latter member is contracted at its lower end and is so shaped, as by 'means of the downwardly-projecting shoulder 23, as to adapt it to form a flame-nozzle in the sense above in- IOO dicated. The other parts of this embodiment are substantially the same as in that first described.
In Fig. 7 is shown another modification of the embodiment shown in Fig. 5, the parts being reversed and the threaded portions being formed upon the inner surface of a ring 24, secured within spool 25, and the asbestos wicking being secured about the lower end of supporting member 26. Although in this embodiment the flame-nozzle is formed upon the spool, it will be seen from the construction above set forth that this may be changed so as to cause supporting member 26 to perform such a function, if desired. The means ot' assembling this embodiment and the operation oi' the same are substantially identical with those previously described.
Although the above description has reference to a burner in which the mantle is suspended by its upper part, it will nevertheless be obvious that the device may be used in connection with mantles which are mounted in any other position. It will also be seen that the means of suspension is not limited to a gas-burner, but will have a broad application in similar devices.
As many changes could be made in the above construction and many apparently widely different embodiments ot' my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
