To all 'whom t may concern.-

Be it known that I, LEE S. CEADWICK, a citizen of the United States, residing at East Cleveland, in the county of Cuyahoga and State of Ohio', have invented a certain new and useful Improvement in Oil-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention pertains to an improved wick carrier for use with oil stoves or burners of the type wherein a tubular wick is supported by and about a wick tube, the wick being equipped with a carrier for cooperation with the wick raiser.

It is essential that an accurate and denite adjustment be maintained between the carrier and wick so that, as the wick is raised, it will be affected alike at all points throughout its circumference and will produce an even iame of substantially the same length and character all the way around. Wicks of the sort in question, as is well known to those familiar, with the subject, are loosely woven and very soft (so as to readily absorb the oil and by capillary attraction conduct it to the upper end or exposed portion ofthe wick), and because of these characteristics the wicks are easily stretched out of shape and normal size. Infact, the Wicks are so elastic that to an experienced person they would seem to be over-size as compared to the cary riers and wick tubes wherewith they are intended for use, and would require considerable manipulation to lit them to these arts.

p Heretofore wicks have been furnished to the public by stove manufacturers of a size and shape suitable for use with the type of stove above referred to, and the user has had to remove the wick carrier from the stove, discard what remains of the old' Wick, t the new wick within the carrier, and then introduce the wick and carrier into the stove or burner.

This operation has been found tedious and extremely diliicult in the unskilled and '1nexperienced hands of the users, and invarl'- ably some detail essential to properly placing the Wick within the carrier has' been neglected or overlooked which results 1n the failure of the stove to properly perform its function and consequently in a general condemnation of the stove.

' It is the objects of this invention to provide, for presentation to the trade as a single unit, a wick and an inexpensive wick carrier permanently united in proper relation to each other;v which is of such nature as to reduce to a minimum the work of inserting a new wick into a stove or burner, enabling persons unskilled and unacquainted with the principles of the stove or burner to properly insert a new wick without the ditculties above set forth; which insures subsequent satisfactory 4operation of the stove, so far as the wick is concerned; and which may involve means for temporarily holding the wick distended and which facilitates the application of the wick to the wick tube of the burner, such means remaining Within the wick during storage and shipment, and preferably being automatically displaced by a part of the burner during the application of the wick.

A further object is to locate the means for. connecting the wick and carrier below the plane of the carrier stops so that inten ference of such means with the operation of the Wick carrier is impossible.

In the accompanying drawings, Figure l is a perspective view of the unit comprising a wick and wick carrier; Fig. 2 is a central vertical section through the same; and Fig. 3 is a central vertical section through a stove, showing a wick and wick carrier unit therein.

The wick, which is designated 1, is of tubular form, slit upward from its lower end on eachvside, as indicated at 2, and spaced downward a suitable distance from the upper end of the wick and completely surrounding it, is the carrier 5. The carrier is of thin cheap metal, and is freely perforated, as indicated at 6. The upper land lower edges of the carrier are provided with teeth 8 which are embedded into the matethe carrier throughout its circumference.

' Stops 9 are struck out from opposite 'sides rial of the Wick so as to hold the wick to top of the wick to a point well below the upper end of the carrier, the tube 12 being of substantially the same diameter as the inner wick tube of a stove or burner.

In Fig. 3 I have shown a type of stove wherewith my invention is adapted for use. The stove comprises a reservoir 15, centrally within which is supported a wick tube 16, and a Hame spreader 17 reposes within the upper end of this tube. What is known as a gallery 20 has a threaded portion that is adapted to be screwed into a threaded opening in the top of the reservoir, and the bottom of the gallery is turned inward where it has connected to it the lower end of an outer wick tube 21.

When it is desired to rewick a stove, the flame spreader is disconnected from an anchorage ring 25, fixed within the inner wick tube, and is removed. The gallery is un-l screwed and lifted upwardly from about the inner wick tube. After the old wick has been withdrawn from the: inner `wick tube, the split lower end of new wick is projected down over the wick tube 16 with one of the slits 2 astride the wick raiser pinion 26, se-

.cured to the spindle 27. Thus the wick may be lowered until the pinion 26 is only a slight distance below the Vwick carrier before it is obstructed by the pinion. Now by forcing the wick carrier farther downward, the pinion 26 is caused to ride over the brief extent of wick between it and the carrier until it is engaged by the lower end of the carrier and rotated to project its teeth into the perforations 6. Now upon rotating the spindle 27 in the proper direction -by the usual operating handle connected thereto exterior of the reservoir l5, the wick carrier and wick may be fed downward along the tube 16, the temporary tube 17 meanwhile beingl forced out of the upper end of the wick by vits engagennnt with the upper end -of the inner wick tu e.

By reason of the permanent connection be-y tween the wick and carrier; the holding of the wick firmly to the upper end of the carrier throughout its circumference by the teeth 8 (wherewith the wick is maintained in engagement by the tube 12 until the wick is finally in place, and thereafter by the tube 16) and by reason of the further fact that the upper end of the wick is previously treated by the manufacturer so that it is in condition for immediate use and bears a proper relation to the wick carrier, the stove is ready for service as soon as the wick has been inserted and the gallery 2O and flame spreader 17 have been returned to their respective places.

Excessive upward movement of the wick carrier is prevented by the engagementof the stops 9 with the bottom of the outer wick tube-21, and since the rivets 10 are below the plane of the stops no interference between the rivets and adjacent parts of the structure is possible.

The plicbility of tlvfI wick material rallows the inner endsI of the rivets 10 to be so embedded into the material that there is no chance of the rivets interfering with the opleration of the wick upon the inner wick tu e.

Having thus described my invention, what I claim is v 1. In combination, a tubular wick, a wick carrier surrounding the wick, stops projecting from the outerside of said carrier, each stop havinga portion arranged for engagement with an abutment, and fastening 4means for attaching the wick to the carrier and situated on the side ofthe stops remote from their abutment engaging portions.

2. In combination, a wick, a wick carrier provided with projecting stops, and fastening means connecting the wick and carrier and protruding in the direction of the stops beyond the surface of the carrier and located below the plane -of said stops.

3. In combination, a tubular wick, a carrier surrounding the wick, said carrier being provided with laterally extending stops, and

rivets connecting the wick and carrler the heads whereof project beyond the outer surface of the carrierand are-located below the plane of the aforesaid stops.

In testimony whereof, I hereunto affix my signature`in the presence of two witnesses.
