Application February 27, 1937, Serial No. 128,092
` The present invention relates to heat resisting trouser legs.
More particularly the present invention relates to wearing apparel for workers who are subjected to the dangers incident to hot splashing metal or the i like. An example of such a worker is a metal molder who must Work in the vicinity of hot molten material which hot material is likely to splash. Garments such as asbestos leggings, overalls and the like have been proposed, but so far as applicant is aware such garments have been objected to by the Workers because they are heavy, interfere with the movements of the wearer, and/or require the worker to change his clothes at his place of work. So objectionable have these garments been to the workers that they have avoided the use thereof to the jeopardy of their own safety.
An object of the present invention is to provide a garment which may be part of the ordinary trousers worn by a worker and will not interfere with his comfort or movements.
A further object is to provide a garment which by a simple sewing operation or the like may be substituted for the bottom portion of the ordinary trouser leg i and which will effectually resist splashes of hot molten material.
A further object is to provide a trouser leg having a portion thereof composed of heat resisting l material, which trouser leg will form no pockets for catching globules of molten material and which will not interfere with the movements of the wearer thereof.
A further object is to provide an improved pro- 5 tective device for those who must be in the vicinity of splashing molten material, which will be convenient and agreeable to the wearer.
A further object is to provide an improved protective device which is so inconspicuous that the .l wearer will have no objection to wearing it on the streets while en route between his home and his place of work and return.
Further objects will appear as the description proceeds.
5 Referring to the drawing- Figure l is a view of the legs of a wearer of one embodiment of the present invention;
Figure 2 is a sectional view, on an enlarged scale, of certain details of construction; and
0 Figure 3 is a View similar to Figure 2 but showing a modification.
The numerals Il'I-Ill represent trouser legs of which the upper portions I I-II are of the ordinary material of which trousers are commonly The lower portions of the trouser legs Ill- Ill `are tubular members I2--I2 secured to the upper portions II-II. Said tubular -members I2-I2 may be made of asbestos or other material having the advantage of resisting heat. As shown in Figure 2, each tubular portion I2 may be provided at its bottom with an inturned hem I3. Secured to the top of each tubular member l2 is a flexible fabric tubular member I4 having its lower edge inwardly turned to provide the hem I5. The upper extremity of the tubular member I2 is disposed inwardly of the hem I5. The upper extremity of the tubular portion I4 is disposed inside the upper portion II of the corresponding trouser leg. Preferably the lower extremity of the upper portion II is turned inwardly to provide the hem I6. The upper portion II of the trousers, the tubular portion I4 and the tubular portion I2 may be united by stitches.
The upper extremity of the tubular portion I2 of heat resisting material may stop just below the knee of the wearer. Inasmuch as the tubular portion I4 is of flexible material, and inasmuch as the upper portion I I is of the ordinary material of which trousers are made, there will be no interference with the knee action of the wearer. The flexible tubular portion I4 may be united to the tubular portion I2 at the factory and said tubular portions I2 and I4 may be sold as a unit. A housewife equipped with needle and thread may sew the tubular portion I4 to the upper portion II of the trouser leg. In many instances, of course, trousers will be utilized which have been worn to such an extent that the wearers do not desire them any longer for regular street Wear. The bottom portions of such trousers will be removed and the protective tubular portions substituted therefor.
The embodiment shown in Figure 3 omits the flexible tubular portion I4, the heat resisting tubular portion I2 being united directly to the upper portion II of the trouser leg, preferably at a region just below the knee of the wearer. The construction of Figure 3 does not have the advantage of the construction shown in Figure 2 in that the housewife may attach the protective portions I2 by sewing only through exible material. However, the construction shown in Fig,- ure 3 presents no very serious difliculties to the housewife in sewing the portion I2 in place.
rll'he described embodiments of the present invention do not present an unsightly appearance and Workers do not object to Wearing them from their homes to their places of employment and back to their homes. Inasmuch as the workmen may at their homes don the trousers including the protective portions and do not have to change at their places of employment, and inasmuch as said trousers are neither uncomfortable nor inconvenient, they are perfectly willing to wear the protective devices.
Inasmuch as the tubular portions l2 need not be bound tightly to the legs or ankles of the wearer, he gets plenty of ventilation inside the protective members, and therefore he does not object on that score. Of course, the worker may use heat resisting shoes such as molders are well acquainted with. It should be noted that the present invention forms no upwardly presented pockets or ledges upon which globules of hot molten material may lodge.
Though certain preferred embodiments of the present invention have been described in detail, many modications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.
What is claimed is:
l. A pair of trousers comprising, in combination, an upper leg portion of cloth and a tubular lower leg portion, said lower leg portion including a portion of heat resisting material, the upper extremity of said heat resisting portion being suciently low to avoid interference with the knee action of the wearer of said trousers, the upper extremity of said tubular lower leg portion being disposed within said upper leg portion, said tubular lower leg portion being free of upwardly presented ledges upon which globules of hot material may lodge and being sufliciently large in diameter to permit uninterrupted Ventilation therethrough along the leg of the wearer.
2. A pair of trousers comprising, in combination, an upper leg portion of cloth and a tubular lower leg portion, said lower leg portion including an asbestos portion, the upper extremity of said tubular lower leg portion being disposed within said upper leg portion and being suiciently low to avoid interference with the knee action of the wearer of said trousers, said tubular lower leg portion being free of upwardly presented ledges upon which globules of hot material may lodge and being sufficiently large in diameter to permit uninterrupted ventilation therethrough along the leg of the wearer.
