Specification of Letters Patent.

Patented Dec. 3, 1918.

Original application filed March 28, 1918, Serial No. 225,142. Divided and this application filed July 25, 1918. Serial No. 246,696.

To all whom it may concern.

Be it known that I, J ULES ASGHEIM, a citizen of the United States, residing at Cedarhurst, Long Island, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Combination-Leggings, of which the following is a specification.

My invention relates to combination leggings having an interior resilient foundation which always tends by reason of its resilience to assume a definite and predetermined normal shape, and a face portion which is combined with the said foundation so as to present a smooth and unwrinkled appearance, the connecting means being such, that this combination legging can be freely bent without any wrinkles being formed in the said face portion and without any separation of the foundation and the face portion.

More particularly, my invention is directed to making a combination legging having a foundation consisting of a flexible split leather which has been shaped into a definite and predetermined form, namely the correct and perfect outline of the human leg, and which has sufficient resiliency to always tend to assume this predetermined form, and a face fabric of canvas or similar stretchable fabric which is combined with the leather so as to prevent the formation of wrinkles in the said canvas at any time. A leather merely consists of animal fibers, it is obvious that a number of other materials composed of connected fibers having equivalent properties could be substituted therefor.

A preferred embodiment of my invention is disclosed in the following description and drawings, in which,

Figure 1 is a perspective view showing how my improved legging is put on,

Fig. 2 is a front view of my improved legging showing the same unfastened,

Fig. 3 is similar to Fig. 2 and shows a legging fastened,

Fig. 4 is a perspective view showing how the leather foundation is shaped,

Fig. 5 is a front view showing the connection of a different form of fastener,

Fig. 6 is a front view showing the legging fastened,

Fig. 7 is a central vertical section, somewhat enlarged, of Fig. 6,

Fig. 8 is a section along the line {I of Fig. 6, and

Fig. 9 is a detail showing the connection of one of the complementary fastening A piece of leather 1 which has been cut substantially into the shape illustrated in Fig. 4 is immersed in water for about thirty minutes at ordinary room temperature, that is between and 70 degrees F. This period of immersion may vary for the difierent kinds of leather, but thirty minutes is the average time for a piece of rough unfinished leather, whose pores have not been filled up and which may be of a cheaper grade or variety than the ones used for making leather leggings or puttees composed of leather alone. v

As a result of this immersion, the pores of the leather take up the water, and it becomes very soft and pliable. It is now stretched into the final shape Which is desired, and which should be such so as to fit the leg of the wearer, of which the wooden mold or form 2 is a duplicate.

The leather is well stretched to make it assume its final and predetermined normal shape, and is then secured around the form 2 in its moist and stretched condition by means of a number of tacks 3. The form 2 with the leather 1 fastened as before described, is now dried by means of a current of Warm air having a temperature of substantially 85 degrees F.

It is undesirable to dry the leather too quickly as the sudden generation of vapor, if too violent, will enlarge the pores of the leather too much for the purposes of the treatment later to be described. 011 the other hand, it is desirable to enlarge the pores of the leather to a certain extent so as to fit it for the said treatment. The said temperature of 85 degrees F. is generally satisfactory and as a result of this drying treatment the pores of the leather are substantially enlarged so that they are readily visible with a magnifying glass of low power such as an ordinary reading glass. The surface of the leather also becomes roughened by this treatment and presents a number of minute projections and depressions.

After the leather has been thoroughly dried, it is now ready for the next treatment and if the surface is not sufficiently rough, which can be determined by running the tips of the fingers over it, sand paper may be used to give the surface of the leather the desired roughness.

The effect of soaking, stretching and dry- 7 the form 2, in dried and stretched condition,

its outer side or surface is completely covered with a cement which preferably is a viscous rubber cement dissolved in benzin. This cement should be so viscous that if a pencil or the like be drawn across its surface a noticeable line is formed which remains apparent for several minutes.

At the same time a piece of canvas 4, which has been cut into the shape shownin Fig 4, has the inner surface thereof also covered with this cement. The film of cc ment on the leather foundation and the canvas face should be as thin as possible, for the purposes later described.

The canvas is-so out that it is stretchable along the line at right angles to the axis of the form 2 and of the legging, and is" also stretchable in the perpendicular direction.

The leather 1 is kept upon the form 2 at a temperature of between 60 and degrees F. until the cement is dried out so'that it has the properties of a somewhat plastic solid so that it requires a perceptible pressure of the finger to cause it to change its shape. The canvas covered with cement as before described is also subjected to the same treatment.

As the cement has not been forced up to i the present time into the pores of either the leather or of the canvas, it forms a layer upon their surfaces of' a somewhat irregular exterior.

The canvas is now placedsymmetrically over the leather upon the form and is strongly pressed thereon, the aforesaid lay ers of cement being of course in contact.

The cementing is performed by means of a small tool like a knife having a blunt, rounded edge, so that the pressure of the hand produces a considerable pressure per square inch and the leather foundation and the canvas facing are first pressed together along their median lines, that is on the line opposite to the tacks 3. Then the operator presses a part of the canvas adjacent this median line onto the leather by means of the tool, and strongly stretches the canvas in a direction at right angles to the axis of the legging, and while the canvas is held in this stretched condition, he forces it against the leather with the said tool so that the leather and canvas are cemented a short distance on one half of-the fabric,'

and then for a short distance on, the other half. The small tool is also rubbed on the canvas in a direction parallel to the axis of the legging so as to uniformly cement the canvas to the legging without the formation of any wrinkles. The fabric may thus be also stretched in a direction parallel to the axis of the legging, either by the hand or by this tool.

By the simultaneous rubbing and pressing, the canvas is uniformly stretched, and the cement is so hard that it is forced by thepressure into the pores and inequalities of the leather and into the pores of the fabric so that the tension of the canvas is maintained because the cement does not al-f low it to spring back into its untensed and unstretched condition.

The pressure may be so powerful as to force the canvas substantially into contact with-the little projections on the roughened surface of the leather, the cement being driven into the canvas, and into the little holes on the surface of the leather as well as into the pores of the leather.

After this is done, the canvas is folded around the leather and is stitched along the lines 5 and 6 as shown in Fig. 2, after be ing cemented at the folds.

It is desirable to cement a piece of nonstretchable tape 7 to the top of the leather before the canvas is applied as this assists in maintaining the leather foundation in its predetermined shape, where the wear and tear are particularly severe.

Of course, the legging is removed from the form before the stitching takes place and the fact that the cement exists in the before mentioned non-flowing condition before the joining takes place is shown by the fact that substantially no cement is squeezed over the margin of the leather.

Sincethe canvas has been stretched and simultaneously cemented to the resilient leather, which is sufficiently stiff to have a permanent shape like an ordinary leather legging or puttee, the combination legging can be freely bent and manipulated withoutany wrinkles being formed, and without any separation of the canvas and the leather, and it always springs back to the desired form. This is highly important as a smooth unwrinkled surface is absolutely necessary to give the legging a neat appearance and be.- cause the treatment with the rubber cement before mentioned makes the combination legging waterproof, and the fact that the canvas facing always contacts with the leather foundation without any wrinkles, prevents the rubber cement from being chipped off by a blow or the like. The stretching of the canvas is particularly desirable, although not always necessary, because this tends to make it always cling closely to the leather.

To fasten the legging, an ordinary strap 9 may be applied which is sewed on at 10 and can be passed on the inside of the legging through slots 11 and 12 and finally be secured to the buckle 14, as shown in Figs. 2 and 3.

Another form of fastening is shown in Figs. 5 and 6. A spring 15 is secured upon the outside of the legging by means of rivets 17, a point 18 being caused to project on the inside through a slot 19 and a strip 20 pasted over the outside of the spring to cover it.

A strip 21 of leather may also be pasted on to the bottom of the inside of the legging so as to prevent it from contracting and to protect the fabric. This is accomplished by causing the leather 21 to project downwardly sufficiently.

The point 18 fits into a socket 191 having a plate 120 so that the point 18 does not rub on the fabric and spoil it. I It is desirable to quickly stitch the fabric and leather together after the cementing in order to prevent the cement from slowly yielding, and thus allow the fabric to lose its tension.

What I claim is 1. A combination legging comprising a fabric facing and a foundation of relatively stiff and resilient material, the material of said foundation being sufficiently stiff and resilient to always tend to assume a predetermined normal shape, similar to that of the leg of the wearer, the said facing being unwrinkled and being cemented to said foundation throughout substantially its entire surface of contact with the front of said foundation, and being so yieldable that it partakes of the bending movements of said facing without becoming separated therefrom and without becoming wrinkled.

2. A combination legging comprising a stretchable fabric facing and a foundation of relatively stiff and resilient material, the material of said foundation being sufficiently stiff and resilient to always tend to assume a predetermined normal shape similar to the leg of the wearer, the said fabrlc being stretched and cemented in a tensed and unwrinkled condition to said foundation throughout substantially its entire surface of contact with the front of said foundation, and being sufiiciently stretched so that it partakes of the bending movements of said foundation without becoming separated therefrom and without becoming wrinkled.

3. A combination legging comprising a fabric facing and a foundation of relatively stiff and resilient leather having a porous and rough front surface, the said leather being so stiff and resilient that it always tends to assume a predetermined shape similar to that of the leg of the wearer, the said fabric being unwrinkled and being connected substantially throughout its entire surface of contact with the front of said leather by a cement which has partially penetrated the adjacent faces of said leather and facing, the said fabric being so yieldable that it partakes of the bending movements of said fac-. ing without becoming separated therefrom and without becoming wrinkled.

4. A combination legging comprising a stretchable fabric facing and a foundation of relatively stifi' and resilient leather having a porous and rough front surface, the said leather being so stiff and resilient that it always tends to assume a predetermined shape similar to that of the leg of the wearer, the said fabric being stretched and cemented in a tensed and unwrinkled condition to said foundation by a cement which is sufficiently strong to maintain the fabric in said stretched condition and which has penetrated the adjacent faces of the said fabric and leather, the said fabric being sufiiciently stretched so that it partakes of the bending movement of said foundation without becoming separated therefrom.

5. In a combination legging, the combination of a fabric facing and a foundation of relatively stiff and resilient material that always tends to assume a predetermined normal shape similar to that of the leg of the wearer, the said fabric being connected to the said foundation in a stretched condition by a cement sufficiently strong to maintain it in said stretched condition.

6. In a combination legging, the combination of a stretchable fabric facing and a foundation of relatively stiff and resilient material that always tends to assume a predetermined normal shape similar to that of the leg of the wearer, the said fabric being stretched over the said foundation in an un wrinkled condition, and means for maintaining the said fabric in its tensed and unwrinkled condition.

In testimony whereof I hereunto afiix my signature.
