ALEXANDER FOLLEAU, OF SAN FRANCISCO, GAIJIIORIIIA.V

Letters Patent No. 111,115, dated January 24, 1871; antedated January 13, 1871.

IMPRovEMENT IN TRUssEs.

The Schedule referred to n these Letters Patent and making part of the same.

To all whom it may concern i Be it known that I, ALEXANDER FOLLE'AU, of the city and countyof San Francisco, State of California,

Vhave invented an Improved Truss; and I do hereby declare the following description and accompanying drawing are snfcient to enable any person skilled iu the art or science to which itl most nearly appertains to make and use my said invention or improvements wit-hout further invention or experimenu My invention relates to` an improvement in trusses, such as are applied and worn on the person in case of hernia or rupture and Inconsists in the use -cf a secondary pad within the ordinary pad, and so constructed that it may be 'made to lgive additional pressure toward the center.

Referring to the accompanying drawing for a more lcomplete explanation of my invention- Figure 1 is aback view of the whole device.

Figure 2` is a iew showing the back of the pad.

Figure 3 is a sectional view showing the secondary pad.

A A are the two parts of the compressing spring, which meet and are pinned together at a, so that they are allowed some motion up and down, or in the direction of their edges.

The two parts of the springpass respectively through the staples or guides B B, which are attached to the back pad G.

llhese guides, while allowing a freedom of motion; up and down, canse the two parts to act as one whole spring with reference to the compressing pad D, which is fastened to oucend of the spring. rIhis end ofthe spring is slightly enlarged, and has a curved slot, li, through it. p'

The pad is connected with the' spring by a screw, c, which passes through the sprintr and the metal back plate E of the pad.

A screw, (I, passes through the slot l), and enters the plate E, and may be set so' vas to hold the pad in any position desired.

In order to hold the pad more securely, a number 'of small holes, e c, are pierced-through the end of the spring in an arc of a circle, having the screw c as a center, and a pin rising from the plate E may be entered into either of these holes, as the angle admits, thus preventing its slipping. f

Within the outer pad D is placed a smaller pad, G, which may be moved back'so as to allow the face oi' the outer pad to become flattened, or rather to assume the vcurve which would be natural to a pad of vits size.

When .it is necessary to have a greater pressure, and to confine it to a. smaller space, the screw H,

which operates theinner pad, is turned and is forced forward, thus changing the shape of the pad and reducing the bearing surface to as small aspace as may lbe necessary. v

This is very eiective, asit never allows the parts to protrude beyond the ring when any sudden or violent exertion is taken; and it' the inner pad is pressed well forward, it tends-toiiritate the edges of the ring, so that they may be broughty together and permanently joined again, this form of truss often effecting the entire cure without any further operation.

Having thus .described my invention, What I claim asnew, and desire to secure by Let- The combination, with the pad D, of the auxiliary adjustable-pad G, arranged beneath the surface`of the saule, substantially as described.Y

In witness whereof I have hereunto set my hand and seal.
