SAFETY DEVICE FOR AUTOIVIOIBILES.

Specification of Reissued Letters Patent. Reissued D131. 30, 1920.

Original No. 1,222,828, dated April 17, 1917, Serial No. 100,801, filed May 31, 1916. Application for reissue filed January 18, 1918.

ning over a person or any other large ob- 'ect. 3 Another object in view is to provide an improved guard which will prevent a person struck by an automobile from falling beneath the Wheels.

A still further object in view is to provide a guard for automobiles which will cushion the blow when the automobile runs against an object and will also, at the same time, apply a special set of brakesto the wheels of the automobile.

A further object of the invention is to provide not only a guard for preventing ob jects from falling beneath the wheels of the automobile, but to present means which will act as emergency wheels in case the tire of the automobile gets out oforder and is unusable, and to provide means for raising and lowering said wheels, and for holding them in adjusted positions.

A further object of the invention is to provide a bumper-bar supported from the knuckle-joint members of the vehicle that will be carried in front of, and be dirigible With the front wheels; also'to pivotally connect said bumper-bar to the'braking mechanism of the two front wheels, in such man nor that the brakes will be applied to both of said wheels whenever the bumper-bar strikes a foreign body with sutlicient force.

Referring to the accompanying drawings by numerals, 1 indicates an automobile of any desired kind which is provided with wheels 2 of any suitable kind having pneumatic tires 3. It is evident that any kind of vehicle could be substituted for the automobile 1 without departing from the spirit of the invention and also any kind of wheel and tire, as these members do not form any part of the invention. Connected to or partially surrounding each wheel is a guard 4:, tliefront guards being provided with curved extensions 5 for preventing the wheel from running over any person or anything of any appreciable size. The front guards at are connected by a bumper-bar 6 and also,

Fig. 4 apshield 7, as shown in Fig. lVhen the shield 7 is used the same is connected to the two frontguards 4 in any suitable manner and extended from one guard to the other, the connection being preferably by hinges 8 and 9, as shown in 2, so as not to interfere with the steering of the automo- The shield 7 is preferably divided section 10 hinged at 11 to the upper section. This is desirable when the device is used in winter and there is snow on the ground as otherwise the guard will gather upthe snow. When the device is used and there is an appreciable layer-of snow on the ground the section 10 is hinged upwardly and secured in any suitable way in a raised position.

automobile should strike against a person or any other vehicle or article. The bar 6 is hinged at12 and 13 to the arc-shaped shields '14 and 15, respectively. These shields are of identical structure so that a description of one will apply to both.

The bar 6 is intended to act as a. bumper-bar, orbufhng member, in case the .if desired, by a wire mesh or chain mesh As shown in Figs. 5 and 6 our brakin mechanism comprises the shield 14 whic has a bar or inwardly extending member 16 which projects through a suitable opening or slot 17 in the guard 4 and has secured to the end thereof a brake shoe 18, which brake shoe will press against the tire 3 in case the pressure on bar 6 is considerable. This will prevent further rotation of the front wheels.

and thus produce astopping action in addition to the fact that the automobile is being resisted by the article struck. In'this way the automobile will be brought to a stop quickly, especially when assisted 'by the driver, and without injuring to any considerable extent either the automobile or the person struck. In case a person is struck and is knocked down he cannot be run over, as the members 5 on the guards 4 will push him along in front of the automobile, but if that the resistance of the object struck will help stop the automobile and in addition will cause the brake shoe 18 to be applied to the front wheels, thus further assisting in the quick stopping of the automobile.

, The guard 4 may be variously constructed but is preferably arranged with a front and back member and two side members so as to almost encircle the wheel, the lower e'dge.ex-. v

tending near to the ground while the upper edge is preferably above the hub so as to insure against any person coming in contact with the wheel.

As shown in Fig. 4, the outer side member of the guard is supported upon the wheelhub, while the inner side member thereof is attached to the knuckle-joints by ring members 10, with threaded portions extending into part of the guard. The guards, therefore, with the elements supported thereby, including the braking mechanism, theemergency wheels and the bumper-bar, are dirigible with the front wheels of the vehicle.

The entire construction of the guard 4 is preferably comparatively strong so as to act properly as a guard and in addition to act as emergency or temporary supporting means in case the tire 3 should become unusable, as for instance, by .a puncture or blowout. When acting in this capacity the arrangement shown more particularly in Figs. 4 and 5 is used on each of the guards. This arrangement comprises a runway 20 in which a sliding member 21 is fitted, the arrangement being preferably somewhat on the order of a dovetail so that member 21 cannot accidentally become disengaged. A stub shaft 22 is mounted on the lower end of the slide 21, said stub shaft carrying a wheel 23 preferably formed with one or more ridges 24: whereby the wheel will prevent skidding when the wheel is in normal position as well as when the wheel is being used in an emergency case. The slide 21 is provided with an extension or shoulder 25 against which spring 26 presses, said spring also pressing against the block 27 which is rigidly secured to the guard 1 by a bolt 28. The sliding member 21 slides up and down past the block under some circumstances. On one edge of the sliding member 21 are arranged teeth 29, which teeth are positioned an appreciable distance apart so there will be a considerable loose motion between the same and the gear wheel 30 whereby when the parts are in the position shown in Fig. 5 the wheel an appreciable distance without operating wheel 30. This is to allow the wheel 23 to act as an anti-skidding device without interfering with the resiliency of the tire 3.

When the tire 3 has become unusable and is deflated the weight of the automobile will force the guard 4 and the gear wheel 30 downwardly until the same rests on one of .the teeth of the rack 21 and thereby become supportedon wheel 23.

If the downward movement of the axle of the automobile is too great wheel 23 may be operated for causing the guard 1 and associated parts to be elevated, said operation being by a wrench 31 fitting the squared shaft 32. The wrench 31 is provided with a rotating ratchet wheel 33 held against reverse movement by a pawl 34, the hole 35 in the wheel extending entirely therethrough so that when it is desired to rotate the shaft 32 in one direction the wrench is placed in position with one face toward the wheel 30,

and when it'is desired to rotate the wheel in the opposite direction the opposite face of the wrench is placed next to the wheel 30. A double acting ratchet wheel 36 is rigidly secured to the gear wheel 30 and coacts with the pawls 37 and 38, which pawls are pivotally mounted on the guard 4: and are connected by a link 39. Whenthe pawls are in the position shown in Fig. 5 the same will limit the upward movement of the slide 31 but will not limit the downward movement thereof, thus allowing the wheel 23 to always remain in contact with the ground. Also, when the pawls are in this position, the sliding member 21 may be moved downwardly by turning the wheel 36 by means of the wrench 31, so that these'parts, together with the emergency wheel, may be used to jack up the driving wheel in order to replace a tire, or for other purposes. In

23 may move upwardly the same will cause said case it should be desired to elevate the wheel 23 the position of the pawls will be reversed and then the shaft 32 rotated for rotating gear wheel 30 to any What we claim is:
