SHOE HEEL.

Application led November 23, 1922. Serial No. 602,674.

To all 'whom it may concern:

Be it known that I, HENRY J. P. Ro'rrenn, a citizen'of the United States, residing at Maspeth, in the borough of Queens, city and State of New lYork, have invented an Improvement in Shoe Heels,'of which the following is a specilication.

This invention relates to a shoe heel and more particularly to that type of heels for boots and shoes in which there is provided a revoluble tread and devices for turning the revoluble tread a partial revolution each time the heel is raised from contact with the walking surface. The object of the invention is the provision of a heel l*of this type which is of comparatively inexpensive construction and which is preferably operated through gears and associated Vmechanism so as to cause the action thereof to be absolutely positive, and the shoe heel made in accordance with my invention will be hereinafter more particularly described.

In the drawing: A

Fig. 1 is a side'elevation and partial sec# tion showing the application of my improved heel in use in a slipper.

Fig. 2 is an enlarged central cross section showing the tread member in the raised position.

Fig. 3 is a similar view showing the tread member in the lowered position. f

Fig. 4l is a section on line 4-4,Fig. 3, and

Fig. 5 is a sectional elevation illustrating the construction ofthe drum, gear, collar and shaft employed in the heel.

By reference to the .drawing it will be seen that in carrying out the invention I employ a heel, the body portion of which is indicated at 10; and which may be made of any suitable material and provided with a hole or opening 11. As will be understood the body of the heel may be attached to a slipper 12 or a boot or shoe in any suitable manner.

At the lower or outer end of the heel I employ a plate 13 which may be connected to this end of the body of the heel in any desired manner. At the opposite end of the heel, that is at the upper or inner end thereof or adjacent the same there is a cross plate or bar 14.- This'is set in oppositely disposed recesses provided therefor, androne end 15 of thev cross plate isl secured to the heel by ascrew 16 and the opposite end 17 of the crossy plate is similarly Secured intheheelbyascrewlS.. Y f

Mounted in the plate 13 'therel isa drumV 19. This is journaled in an .opening 2O in the plate 13 which provides a bearing therefor. At the inner end of the drum 19. there is a flange 21 normally adapted to bear'against the inner surface of the plate, it being understood that the drum19 is revoluble in the bearing and also shiftable therein longitudinally of the heel. I also employ a shaft 22. At one end` this is provided' with a circularly flanged head 23fadapted to be received in a recess 24 provided thereforin the inner end ofthe drum 19. Mounted on the shaft 22 there isa sleeve 25. AThis sleeve 25 also extends into anj opening 26 provided therefor in the inner end of the drum 19and is suitably connected to the drum 19 in any manner to .permit the drum and sleeve to also turn onthe shaft 22 and the head .23 thereof. At the outer end of the sleeve 25 there isa bevel gear 27. This, as will be understood, may be made an intergral part of the sleeve or connected thereto in any suitable manner. The opposite or inner end 0f the shaft 22 is flattened as indicated at 28 and passes through a. slot provided therefor and acting as a .bearing in the cross plate or bar 14. /These' parts are normally maintained in the position indicated in' F ig. 3 by a spring '30, secured at one end between the head ofy the screw 16 and the upperface of the cross plate or bar la and bearinglat its opposite end against the flattened end of the shaft22. By this structure, as will be understood, the drum 19 and its flange 21 are revoluble in the bearing in the plate 13 and are also adapted to turn on the outer end of theshaft 22, together with the sleeve 25 and its bevel gear 27, while these parts together with the shaft 22 are shiftable longitudinally of the heel and the shaft is prevented from turning because of its flattened end passing through and being movable in the slotv29 in the cross plate or bar 14.

Suitably Xed in and extending from the shaft 22 there is a stub shaft 31.'. Mounted on 'this stub shaftis a disk 82. Connected to the'disk 32 at one side thereof is a bevel gear 33 adapted to mesh with the bevel gear en a 27, while at theopposite side of the disk 32 there is a ratchet 34E. Associated with the ratchet there is a pawlr 35 which is pivotally connected at one end as indicated at 36 to the side of the cross plate or bar 14, while the free or latch end of the pawlis adapted to engage the teeth of the ratchet. The pawl is normally maintained in posif tion with the latch end thereof in engagement with the teeth of the ratchet by means of a springr 37 or otherwise.

l also employ a tread member which, as indicated, may include a plate 38 which is secured to the under or outer surface of the drum 19 by means of screws 39 or otherwise and to which plate 38 a suitable tread member 40 is attached in any desired manner, it being understood that this tread member may be made of leather, or rubber or other material of which heel treads are commonly constructed. lt will be noted that the tread member 40 is centrally recessed as indicated at 41 not only for the purpose of making it possible to readily attach the plate 38 to the drum 19, but. it provide an annular or tread surface. for the heel so as to make it impossibile for the tread member to wear into ar conical formation, it being obvious that as the wear is onthe outer edgeof the tread member in the revolution of the tread member it would wear into the form of a` cone if it were made to extend entirely across the bottom of the heel, whereas because of the central recess therein the wear on the heel can only7 create an inclined surface eX- tending'from the outer edge to the recessed portion of the tread member.

In the use and operation of the devices comprising the heel as hereinbefore described, the parts are normally maintained in the position shown in Fig. and when the heel is broughtv into contact vwith the walking surface the tread member and the parts associated therewith are shifted longitudinally of the heel to the position shown in Fig. 2. In this shifting of the parts thc drum with the shaft and the gears carried thereby are moved inwardly against the action of the spring 30. ln so doing, as will be obvious, the latch or dog end of the pawi rides over one or more of the teeth of the ratchet 34;. When the heel is raised the action of the spring against the shaft returns the saine and the drum with the revoluble tread member to the position shown in Fig. 3. ln so doing the ratchet 34 in moving outwardly will be turned a partial revolution transmitting a correspondingmovement to the bevel gear 38 which is transmitted to the bevel gear Q7 thereby turning the sleeve 25 and the drum 19 a partial revolution which is also transmitted to the tread member so that each time the heel is raised and returned to the tread surface the tread member is revolved a partial incense revolution to bring a new section thereof at the rear of the heel where in most cases it is first brought into contactv with the tread surface. This, as will be apparent, causes the tread surface of the heel to wear evenly.
