SINGEING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,937, dated May 3, 1904.

A li tion fil d March 10, 1900. Serial No. 8,141. (No model.)

I0 117/ whom it may concern.

Be it known that I, Max SARFERT, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Singeing-hIachines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to the art of singeing textile fabrics; and it consists of a machine for singeing the outside or outer surface of hollow or tubular articles such, for instance, as hosiery for the purpose of removing the fuzz, nap, or lint from the outer surface only thereof, and thus to impart to the article a finished appearance.

My invention further consists of novel details of construction hereinafter fully described and claimed.

Figure 1 represents a side elevation of a singeing-machine embodying my invention. Fig. 2 represents a front elevation of Fig. l, a portion thereof being shown in section. Fig. 3 represents a front elevation of the burnertubes, showing the air-valve in section. Fig. & represents a plan view of a form to be inserted in the article to hold the same in position when being singed.

Similarnumerals of reference indicate corresponding parts in the figures.

For the purpose of illustrating my invention I have shown a machine for singeing hosiery, as this example best illustrates the principle of my'invention, and since my invention has been particularly designed for singeing hosiery and inaccordance with the broad principle thereof I employ two principal instrumentalitiesnamel y, means for supporting the stocking or other article from within and, second, a singeing means, these two means being preferably relatively movable, so as to apply the singeing means to the outside of the stocking to singe substantially the entire outer surface thereof. It is obvious that these principal instrumentalities of which my invention consists can be variously arranged and organized, and in the accompanying drawings 1 have shown one simple embodiment thereof which I have found in practice to be successful and which consists in employing two burners arranged to project their flames toward each other, a pair of driven rollers situated next to these burners, so that when a stocking and a form placed therein to hold said stocking flat is inserted between these rollers said form and surrounding stocking is projected between the burners and the outside of the stocking or its entire outer surface is subjected to the singeing agent, although it is understood that my invention is not limited to this specific arrangement and organization of these instrumentalities. I will now proceed to describe the specific construction shown in the accompanying drawings.

1 designates the feeding-table, which may, although not necessarily, be employed and which is supported in any suitable manner in proximity to the feed-rollers 2. and 3, which are mounted on the shafts L and 5, which revolve in suitable bearings in the framework or housing 6. The shaft 5 is mounted in stationary bearings, while the shaft A is mounted in boxes or bearings 7, above each of which is a resilient or yielding cushion 8, upon which rests the plate 9, against which bears the bolt 10, which passes through a suitable portion of the housing and is locked in the desired position by the jam-nut 11. The shaft 4 and the feed-roller 2 thereon are rotated by any suitable means, as the belt 12 and pulley 13,

and power is transmitted from said shaft 4 to the gear 14, which meshes with the gear 15, mounted on the shaft 5, whereby the latter and its roller are actuated in unison with the roller 2,, At the discharge side of the feed- 5 rollers are located the upper and lower burnertubes L6 and 1?, respectively, which are supported in. any suitable manner and receive the gas orvapor from the supply-pipe 0r vaporizer. 18, the admission of the proper amount 9 of oxygen being regulated by a suitable valve 19, (seen in Fig. 3,) it being understood that each of the burner-tubes are provided with suitable valves 20 and 21, whereby the supply of vapor can be readily regulated.

It will be noted that the discharge jets or openings 2). in the upper burner-tube 16 are out of alinement with the jets 23 in the lower burner-tube and are so arranged that one flame is directed downwardly and the other upwardly, the downward flame in the present instance being in advance of the upper flame, whereby the flames are not directed to a common point, thus minimizing the danger of the flames uniting, and thus burning or scorching the articles passed between them.

In practice I have found it preferable to make the upper burner-tube 16 of greater diameter than the lower burner-tube 17, the jetopenings 23- in the latter being of less size than the jet-openings 22, it being evident, however, that the flame issuing from the ports 23, although smaller than the upper flame, will be equally intense, owing to its natural tendency to travel upwardly. 24 designates a receiving-table which may although not necessarily, be employed for the reception of the stocking or other article after 1 being singed.

To support the stocking or other article from within, so that it can be passed through the machine in a flat condition, I employ a form 25. (Shown in Fig. 4 This form 25 is shown as an ordinary stocking-board, although it is understood that in accordance with my invention the means for supporting the stocking within may consist of. any device inserted within the stocking to support the same in a flat condition while it is being singed. The

stockings are preferably stretched upon this form.

The operation is as follows: The stockings to be singed are supported from within by the form 25, which is so thin that the flames readily reach those portions of the stocking lying over the edges, as well as the portions stretched over. the sides of the form,the movement of the goods being sufliciently rapid to prevent any injurious effects of the flames, and it will be obvious that no singeing action is bad on the inside of the stocking contiguous to said former. The formers and the stockings thereon are propelled in the direction of the arrows seen in Fig. l by the feed-rollers 2 and 3, and it will be seen that all the long surplus fibers or fly will be singed therefrom at one and the same operation, which is an important desideratum in this class of work, as it saves much time and labor,and consequently greatly reduces the cost of the singeing operation. The upper feed-roller being mounted in yielding or cushioned bearings permits a sufiicient vertical movement to compensate for the thickness of the form and surrounding the stockings will be supported in a practically rigid manner during the feeding and singeing operation.

It will be evident that the feedqollers 2 and 3 can, be duplicated orarranged in ,pairs in series and the burner-tubes 16 and 17 also duplicated without departing from the spirit of myinvention, the feed-rollers being actuated in unison by any suitable means.

The vapor used in the burner-tubes can be taken from any suitable source of supply, and it will be evident that, if desired,thejet-

open ings

22 and 23 may be made the same size and the inlet to the lower burnertube reduced, which would result in supplying a less quantity of gas to this tube, whereby the size of the flame would be reduced.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a singeing-machine, burner-tubes arranged on opposite sides of the path of the article to be singed, and feed-rollers for propelling said article between said burner-tubes, whereby both sides thereof are singed at one operation, I
