To all whom it ma cop-tern:

Be it known t at"I,JULns Asonanu, a citizen of the United States, residing at Cedarhurst, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Methods of Making 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 leg in having a foundation consisting of a exi le 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 sufiicient 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. As leather merely consists of animal fibers, it is obvious that a number of other materials composed of connected fiber having equivalent properties could be su stituted therefor.

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

5 and 6.

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 F. This period of immersion may vary for the different 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 acheaper grade or variety than the ones used for making leather leggings or puttees composed of'leather alone.

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 the 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 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. 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 temperatureof 85 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 On the I parent for scribed is also subjected to the with a magnifying glass of low 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 sutiiciently 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 ing is to make the leather quite resilient and springy so that it always tends to assume the shape given thereto by this treatment. and fits snugly and neatly around the leg of the wearer.

While the leather foundation is still upon the form 2. in dried and stretched condition,

power such its outer side or surface is completely covered with a cement which preferably is a viscous rubber cement dissolved in benzene. This cementshould be so viscous that. if a eneil or the like be drawn across "its sur are a noticeable line is formed which remains apseveral minutes.

At the same time a piece of canvas 4, which has been cut'intothe shape shown in Fig. ,4, has the inner surface thereof also covered with this cement. "The film of tre ment on the leather foundation and the can "as face should-be as thin as possible, fl t1 the purposes later described.

The canvas is so cut that it is stretchable alon the line at ri ht angles to the axis. of the arm 2 and of the legging, and also stretchable in the perpendicular direction.

The leather 1 is kept upon the form 2 at a temperature of between 60 and 1*. 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 de same treatment.

is the cement has not been forced up to 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 placed symmetrically over the leather upon the form and is strongly pressed thereon. the aforesaid la) 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 adpicent. this names? 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 logging. 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 together while both are in the stretched eondition This small tool is applied with a strong pressing and rubl'iing motion away from this median line.and toward the said tacks :s. The canvas and leather may be cemented together throughout one half and then throughout the other half thereof; and this is preferable, but the cementing may proceed gradually from both sides of the said line. the rubbing and pressin taking place a short distance on one half 0 the, fabric. and then for a short distance on the other half. The small tool is also rubbed on the cartvas in a direction parallel to the axis of the logging so as to uniformly cement the earn \as to the legging without the iormation 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 the pressure into the pores and inequalities of the leather and into the pores of he fabric so that the tei'ision of the canvas is maintained because the cement does not allow it. to spring into its untenscd and unstretched condition. i

The pressure ma): be so powerful so as to force the canvas :utbstantially into contact,- with the little proiections on the roughened surface of the leather, the cement being driven into the canvas. and into the title, holes on the sur'h ce of the leather as well as into the pores of the leather.

Alter this is doom the canvas i'olded around the leather and is stitched along the lines Ti and d as shown in Fig. 2. after being cemented at the folds.

It is desirable to cement a piece of nonstretrhabhe tape T to the top of the leather before the canvas is applied as this a. sis in nnliotainin the leather foundation m its 'fHltlttP lill'ltti shape. where the wear and tear are parti ularly severe.

()l' course. the legging is renn-ved from the i'ortn before thestitching: takes place and the fact that the eenu-nt exists in the before mentioned noirt'lmving condition be fore the joining takes place is hown by the fact .that substantially no cement is stp'leezcd over the margin of the leather.

Since the canvas has been stretched and simultaneously cenn-nted to the resilient leather, which is sntlicicntly still to have a permanent shape like an ordinar leather legging or puttee, the combination legging can be freely bent and manipulated without any 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 because 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 leg- 7 ging 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 riv- 'ets 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 1y causing the leather 21 to project downwardly sufficiently. I

' 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.

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: In the art of making a combination legging having a fabric facing and a foundation of leather sufficiently stiff and resilien to always tend to assume a definite predetermined normal shape similar to the leg of the wearer, those steps in the art which consist in soaking the leather in water until it absorbs some thereof, stretching it into normal shape. maintaining it in normal shape by holding means. drying it.whilc being so maintained in normal shape at a temperature less than the boiling point of water. and cementing the fabric in a stretched condition to said leather before said holding means are released.

2. In the art of making a combination legging having a fabric facing and a founda of leather sutliciently stiff and resilient to always tend to assume a definite predetermined normal shape similar to the leg of the wearer, those steps in the art which consist in soaking the leather in water until it absorbs some thereof, stretching it into normal shape. maintaining it in normal shape by holding means, drying it while being so maintained in normal shape at a temperature less than the boiling point of water, and cementing the fabric to said leather before said holding means are released.

In the art of making a combination legging having a fabric facing and a foundation of leather sufficiently stifl and resilient to always tend to assume a definite predetermined normal shape similar to the leg of the wearer. those steps in the art which consist in soaking the leather in water until it absorbs some thereof, stretching it into normal shape. maintainin it in normal shape by holding means, drying it while being so maintained in normal shape at a temperature of about 85 F., and cementing the fabric to said leather before said holding means are released.

4. In the art of making a combination legging having a fabric facing and a foundation sufficiently stiff and resilient to always tend to assume a definite predetermined normal shape similar to the leg of the wearer, those steps in the art which consist in stretching the said foundation in a direction at rightangles to the axis of the said legging and maintaining it in the said stretched condition. stretching the said fabric in a direction at right angles to the said axis, cementing the said fabric to the said foundation while both are in the said stretched condition, and then releasing the said foundation, the said fabric being ermanently maintained in its tensioned con ition.

. '5. In the art of making a combination legging having a fabric facing and a orous foundation sufiiciently stiff and resilient to always tend to assume a definite predetermined normal shape, similar to the leg of the wearer. those steps which consist 1n stretching the said foundation in a direction at right an less to the axis of the said legging, stretc ing the fabric at right angles to the said axis and connecting it to the said foundation while both are in the same stretched condition by means of a thick cement which is forced into the said porous foundation without substantially spreading sidewise. the said cement being sufliclently strong to maintain the fabric in itstensed condition before it hardens, and maintaining the said fabric permanently tensed.

6. In the art of making a combination legging having a fabric facing and a foundation sufficiently stiff and resilient to always tend to assume a definite predetermined normal shape. similar to the leg of the wearer, those steps in the art which consist in stretching the said fabric in a iiireetion transverse to the axis of the leg 11 cementing all parts of the said fabric swing and to the said foundation while the said facing is so stretched and while the said foundation has substantially the said normal shape, the resilience of the said foundation being so great that it overcomes the tension of the fabric so that the combination legging alwa s tends to assume the said normal shape, to an the said fabric is always tight! stretched against the said foundation an remains in permanent contact therewith at all parts thereof. a
