Patented July 29, 1947 UNITED STATES ROLLER AND OTHER SKATES Stanley Guttridge, Wanstead, London, England Application September 5, 1945, Serial No. 614,455 In Great Britain September 20, 1944 4 Claims.

This invention relates to roller and other skates and has for its object to provide an improved construction which enables the roller or blade part of the skate to be readily detachably secured to the skate plate and to be insulated therefrom by suitable shock absorbing means. The invention also provides simple means to enable the rollers to pivot for steering.

According to this invention the rollers of a roller skate are mounted upon a separate chassis which is readily detachably secured to the skate plate and is insulated therefrom by shock absorbing means. The chassis may be detached and a blade substituted and secured by similar means, for ice skating.

According to a preferred form of the invention the said securing means comprises apertured lugs projecting downwardly from the underside of the skate plate and which are adapted to receive pins projecting upwardly from said detachable roller T 2 skate chassis or said ice blade.

According to one embodiment the upper ends of said pins are threaded to receive nuts accommodated in recesses in the upper face of the skate plate and which bear upon rubber buffers provided between said lugs and the nuts, whilst according to another embodiment the upper ends of said pins are each formed with recesses adapted to receive the end of a spring loaded locking pin located in the wall of each of said lugs.

The said shock absorbing means comprises rubber buffers provided between said lugs and parts on the roller skate chassis or the ice blade adapted to fit in slots at the bottom of said lugs.

The wheels of the roller skate may be mounted on axles adapted to pivot about steering pins on the chassis and may be provided with steering dampers operating by cam action and adjusting means may be incorporated for alignment of the front and rear wheels.

In order that the invention may be clearly understood and readily carried into effect, reference will now be made to the accompanying drawings which illustrate various embodiments of the invention by way of example. On the drawings:

Fig. 1 is a part sectional side elevation of the invention as applied to a roller skate.

Fig. 2 is an inverted plan view showing the bogie at the forward or toe part of the skate.

Fig. 3 is a side elevation showing the skate plate of Fig. 1 fitted with an ice blade.

Fig. 4 is a cross-section showing an alternative form of quick release for enabling an ice blade to be substituted for a roller skate chassis or vice-versa.

Fig. 5 is a side elevation to a larger scale of a wheel carrying axle housing.

Fig. '6 is a section taken on the line VI-VI of Fig. 5 but including the bogie wheels.

Fig. '7 is an exploded View showing separately the various parts of the wheel carrying axle housing.

Referring to the drawings the skate plate I is shaped to correspond substantially to the outline of the boot or shoe to which it is to be secured and it may be provided with'holes 2 for fixing screws at suitable positions, in any well known manner. The underside of the plate I may be provided with suitable stiffening ribs 3 and downwardly projecting lugs 4 are provided to support the detachable chassis. The skate plate I may comprise a light aluminum or alloy casting with the ribs or lugs 3 formed as integral parts thereof.

The chassis comprises a longitudinal metal rod 5 adapted to be secured in the downwardly projecting lugs 4 of the skate plate I and is provided at each end with upwardly directed steering pins 6 about which the wheels 1 may turn for steering purposes. The chassis member is preferably square at its two ends 8 to engage in vertical slots 9 in the lugs 4 on the skate plate I so that it may move up and down therein and the two ends are connected together by the steel rod 5 of reduced size so as to keep down the weight. The chassis is located and held in the lugs 4 by upwardly projecting pins I0 (see Fig. 1) which pass through the lugs 4 and are secured by recessed nuts II screwed onto their upper ends from the upper face of the skate plate I. Suitable resilient shock absorbing means such as rubber buffers I2 are provided between the lugs 4 and the chassis and also between the lugs 4 and the nuts II on the securing pins on the chassis. The recessed nuts II enable the shock absorbing means I2 to be suitably adjusted. When these nuts II are removed the complete chassis may be readily removed from the skate plate I and if desired a suitably shaped ice blade I3 (see Fig. 3) may be substituted and secured in a similar manner.

Instead of locking the chassis to the skate plate I by means of recessed nuts II screwed onto the upper ends of the pins Ill, the latter may, as shown by Fig. 4 each be formed with a recess I4 into which is adapted to snap the inner end of a locking pin I5 connected to the free end of a leaf spring I6 secured at its other end to the lug 4. Thus by withdrawing the inner end of the locking pin I5 clear of the recess I4, for which purpose the pin may be provided with a knurled head H, the chassis of say a roller skate may be removed and an ice blade 13 fitted in place thereof or vice-versa. This modification provides a quick release means which does not involve the need for unscrewing the nuts H previously referred to. The upper end of each pin I is in this case preferably formed with a tapered part Illa to press the locking pins 15 outwardly automatically when a roller skate chassis or an ice blade I3 i being fitted to the skate plate I to avoid moving the pin 15 manually, the latter snapping back into a locking position when the recess I4 is brought into registration with the inner end of the pin [5.

The front and rear steering pins 6 at the ends of the chassis are preferably inclined to a suitable extent in a forward and rearward direction respectively and are gripped in'split extensions 8a of the squared portions 8 and locked therein by locking screws 81). On each steering pin 6 is mounted a bogie comprising a wheel carrying axle housing l8 and axle 19 for a pair of Wheels 1' and damping means 23 for controlling the steering of the bogie. The housing 18 is provided with a bearing to fit on the upwardly extending steering pin 6 and is secured in position by a washer 29 and a pin 2| passed transversely through the upper projecting end of the steering pin 6. The axle housing is slotted transversely at 22 in a plane approximately at right angles to the axis of the steering pin 6 and in this slot is located a steering damper plate 23. The damper plate 23 is slotted at 26 to fit round the steering pin 6 and a transverse recess 25 is formed in the steering pin in line with the damper plate 23 so that they may interlock and the centre portion of the damper plate will engage against the flat base of the recess 25 in the steering pin 6. The damper plate 23 is pressed resiliently into engagement with the recess 25 in the steerin pin 6 by means of a pair of adjusting screws 26 fitted into the axle housing 18 and are adjustable to press suitable springs 21 against the two ends of the damper plate 23. The springs may engage over spigots 26a formed in the adjusting screws 26. By adjusting these screws 26 the front and rear pairs of wheels I may be adjusted for alignment and the freedom or otherwise of the bogies to turn on the steering pins 6 may be regulated. The inclination of the steering pin 6 will tend to bring the steering into each bogie comprising an axle housing which may swivel about an inclined steering pin, a transverse axle mounted in the housing and supporting a pair of ground engaging wheels on suitable bearings, a steering damper plate fitted in a transverse slot in the housing and having a recess to fit around and against a flat on the steering pin, sprin means mounted in the housing and engaging the damper plate to press the recess therein against the flat on the steering pin and means to adjust the spring pressure on the damper plate.

2. A skate according to claim 1 in which the chassis with its ground engaging wheels is detachably secured to the skate plate and means is provided for readily, releasing it and for securing in its place a chassis having an ice blade.

3. A skate comprising a skate plate with means for attaching it to the users footwear, a longitudinally disposed chassis with means for detachably securing it beneath the skate plate and road engaging wheel bogies at each end of the chassis, an inclined steering pin on which each bogie is mounted for dirigible movement and a steering damper comprising a damper plate engaging in a slot in the bogie housing and slotted to engage a fiat on the steering pin, spring means to engage the outer ends of the damper plate and means to adjust the resilient pressure on the damper plate.

4. A skate according to claim 3 in which the chassis extends longitudinally beneath the skate plate, forked lugs on the underside of the skate plate, squared parts on the chassis which. engage between the forks of these lugs, upwardly projecting pins on the chassis which pass through the skate plate, resilient buiiers interposed between the chassis and the skate plate and clamping nuts on the pins to secure the chassis to the skate plate.
