SPECIFICATION forming part of Letters Patent No. 660,427, dated october 23, i900. v Application lel December l, 1899. Serial No. 738,799. lNo model.)

To all whom, t may concern:

Be it known that I, MICHAEL HALLANAN, a citizen of the United States, and a residentv of the city of New York, borough of Manhattan, in the county and State of New York,

haveinventedanew and Improved Hoof-Pad, of which the following is a full, clear, and eX- act description.

The principal purpose of this invention is to so construct hoof-pads of leather and rubber a's to prevent the separation of thel parts during the use of the pad. In the practical use of hoof-pads constructed of a composite of leather and rubber it has been found that the rubber is frequently knocked off the pad, thus of course destroying the pad. By means of. my invention the rubber is more securely held to the leather and the necessity for sewing is to a large extent done away with, cement sufficing in most cases.

This specification is the disclosure of one form of my invention, while the claims define the actual scope thereof.

Reference is to be h ad to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is an under side View of the pad in use. Fig. 2 is a top View of the rubber section or the pad proper, and Fig. 3 is asec tional view on the line 3 3 of Fig. l.

The pad to which my invention is applied is here shown to comprise a leather backingplate a of the marginal form indicated in Fig. l and a rubbersection or pad proper, b, secured to the under side of the backing-plate a and havinga portion b/ cutaway to receive the shoe c, as. shown, it being understood that the shoe is nailed through the leather plate a into the hoof and that the pad proper, b, is held in position by its connection with the backingplate. At the front edges of the widened heel portion of the pad b and directly adjacent to the cut-away part thereof projections b2 are formed on the pad b, and the horseshoe c has its heel portions reduced, as indicated by dotted lines at c, so that the reduced heel portions of the shoe may lie under the projections b2, thus clamping these portions of the p ad b in position. j the nail-holes of the shoe, at the heel thereof, are arranged directly adjacent to the reduced As shown in Fig. l,

portions c', so that the heel portions of the shoe are held firmly at this point, so as to press firmly on the projections b2 ofthe pad b. Now for the purpose of firmly securing the pad b to the backing-plate ct l construct the pad and back-plate with interengaging surfaces or members, whereby to resist the tendency of the rubber pad to shift or work edgewise from its position von the back-plate, and in lcarrying out this invention I so dispose the engaging surfaces as to offer a resistance in all directions to the strains on the pad. As shown best in Fig. 2, the pad is provided with a number of transverse ribs or corrugations d, extendingsubstantially throughout the wid th of the pad at the heel and forwardly to a point just rearward of the projections Z9, before re- 4fel-red to. The forward portion of the pad b is formed with a n umberof shorter corrugations d', situated at the edges of the pad and disposed approximately in radial position with respect to the center of the before-mentioned forward portionv of the pad. This forward portion of the pad has its middle or central part plane to lie snugly against the back-plaie Ct, forming a broad ceinenting-si'irface. EX- tending continuously throughout the pad b, at the margins thereof, is a groove d2, which forms a small iiange around the margin of the pad. This groove d2 is situated at the ends of the ribs or corrugations d', and the depressions or grooves formed by these ribs run into the marginal groove d2. The leather backing-plate o, is formed with corrugations and grooves to match those of the pad, in the manner shown in Fig. 3. In this View it will be seen that the back-plate a is formed with transverse ribs a at its heel portions, forming grooves on the under side of the plate, which match with the ribs d and with shorter approximately radial ribs a2 at its front portions, forming grooves on the under side of the plate, which match with the ribs d. The plate ct is also formed with a continuous groove a3 in its top face, such groove prod ueing a rib on the bottom of the plate ot, which rib its into the groove d2 of the pad. The

two sections of the device are so formed that their several ribs and grooves will match exactly with each other. The parts ot and b being thus constructed, they are set together, as shown, and cemented in the usual manner.

broken and the pad will remain intact. "providing the marginal groove d2 for the pad,

2 l y p sanfte? The result of this construction is that `the several interengaged ribs and grooves resist the strains `on the pad and prevent the separation of the pad from the back-plate a. It should be understood that in the use of the pad the strain thereon is to a large extent in the plane of the pads. This tends to disrupt the securing means and gives a tendency of the pad to creep on the back-plate. Therefore in my invention, which vprevents the movement of the pad on the backplate, the cement between these two parts cannot be By forming the small marginal iiange, and the corresponding formation as of the back-plate I insure the snug and hermetic engagement of the edges of the pad with the back-plate and constitute what is practicallya seal at the edges, thus insuring the security of the pad at its edges, which, it should be understood, is a very important point, for it prevents a single part of the edge of the pad from becoming detached from the back-plate, in the event of which dirt and other material would enter between the pad and the backplate, to their injury.

Reference to Fig. 3 will show that the heel portion of the parts ct and Z9 is set slightly lower than the other portion of the pad, thus placing the heel of the pad out of contact with the heel of the hoof of the horse, which heel is indicated by the dotted lines in the' figure referred to. This aords a measure of additional resiliency at the heel of the pad and eases the step of the horse. It is clear that the pad being disposed, as in Fig. 3, with its heel out of contact with the hoof Will form a cushioned portion which as the horse treads Will first engage the ground and in yielding will tend to break the force of the blow attending the descent of the horses hoof.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. A hoof-pad, comprising a pad proper of rubber, anda backing-plate of leather, formed with interengaging ribs and grooves on their `opposing faces, and being cemented at such ribs and grooves, the ribs and grooves of the heel portions of the pad and back-plate being disposed transversely and extending substan tially throughout the widththereof, and the ribs and grooves at the front portions of "the pad and backing-plate being disposed in an essentially radial position from the center of such front portions.

2. A hoofp'ad, formed in two parts cemenw4 ed together and having interengaging formations including a marginal sealing rib and groove.

3. A hoof-pad, formed of a rubber pad proper, and a leather backing-plate, provided with interlocking ribs and grooves, and being cemented together at such points, and the pad and back-plate having their margins formed with additional interlocking ribs and grooves producing a seal at the edges of the pad, for the purpose speciied.

4. A hoof-pad, comprising a backing-plate, and a pad proper held thereto, said parts having mating ribs and grooves ranging transversely, and additional ribs and grooves at different angles to the first-named ribs and grooves.

5. A hoof-pad, comprising a front or main portion adapted to lie rmly against the hoof, and a rear or heel portion set away from the hoof normally out of contact therewith, such portion extending throughout the Width of the pad, and being yielding to cushion the tread of a horse. I

6. A hoof-pad, having a main or front portion, and a rear or heel portion, the upper surface of which latter portion is situated in a plane below that of the main or front portion and extends throughout the width of the `pad so that when the main or front portion of the pad is engaged with the hoofthe heel portion will be set away therefrom, for lthe purpose specified.

7. Ahoof-pad,comp1isingapad proper, and a stiff backing-plate laid thereon and to which the pad is secured, the backing-plate being adapted to be attached to the hoof, and the backing-plate and pad being provided with intercngaging formations-on their engaging faces, by means of which formations independent edgewise movement of the pad and plate is prevented.

8. A pad comprising a stiff upper or back plate and a yielding pad proper on the under surface thereof,'and the back-plate and pad proper having intercngaging formations pre.

venting relative edgewise movement of the parte. l

In testimony whereof I have signed my name to this specificationl in the presence of two subscribing witnesses.

MICHAEL IIALLANAN.
