.Ze it known that I, BENJAMIN E. DAKIN, a citizen of the United Statesn'csiding at Washington, in the District of Columbia, have invented certain new and useful Improvements in Attachments for Motor-Vehicles; and Ido declare the following to be a full,clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specificaiion.

This invention relates to attachments for motor-vehicles; and its primary object is to provide mechanism adapted to be attached to the operating-lever of a motor-vehicle for locking and releasing said lever.

A further object of the invention is to pro vide means whereby the extent of movement of the operaiingdever, and consequently the travel of the vehicle, may be regulated with reference to predetermined rates of speed.

it. further object of the invention is to provide regulating or cont-rolling mechanism adapted to be set to permit the vehicle to travel at a predetermined limit of speed and to lock the operating-lever against further movement when such limitof speed is reached.

A further object to provide the operatinglever with an audible signal which maybe conveniently operated by the same hand that moves the lever, whereby the signal may be sounded either simultaneously with the movement of the'lever or while the lever is at rest.

The characteristic features of the invention and its details of construction will be fully described hereinafter in connection with the accompanying drawings, which form a part of this specification, and particularly pointed out in the appended claims.

in the drawings, Figure 1 is a side elevation of the upper portion of the operatingrlever of a motor-vehicle provided with my regulating attachment. Fig. 2 is a longitudinal section of the same. Fig. 3 is a longitudinal section of the handle of the lever, taken on a plane at right angles to that of Fig. 2. Fig. K is a horizontal section of the device for locking the indicator of the attachment. Fig. 5

is a view in perspective of the mechanism arranged with the handle of the lever for locking and releasing the lever, and Fig. 6 is a perspective view of the key for unlocking the indicating device of the attachment.

The reference-n um eral l designates a plate, preferably of approximately triangular-shape, adapted to be secured to the frame or body of the vehicle and having secured to its upper edge a segmental rack 2. On one side of the plate 1 is formed or secured a projecting block 3, having a segmental dovetail groove 4 formed on one side thereof, adapted to receive a curved or segmental slide 5, the outer face of which bears numerals or other characters constituting an indicator for the de vice. The opposite side of the block 3 is provided with a housing or casing 6, within which is arranged a bolt7, beveled at one end, as shown at S, and having a lug or pin .9 projecting therefrom, adapted to enter perforations in the inner side of the slide 5 to lock the latter against movement. Between the ends of the bolt 8 and the wall of the housing 6 coil-springs 10 are interposed, said springs serving to normally hold the pin 9 in engagement with the slide 5.

A special form of key (shown in Fig. 6) is required to release the bolt and unlock the slide. This key is adapted to enterthe open end 11 of the housing and is formed with beveled shoulders 12 and 13 to adapt it to the beveled bolt. The end 14. of the key is forked or bifurcated to adapt it to straddle the pin 9.

15 designates the operatingdever of the vehicle, suitably fulcru med to move in the circular plane described by the segmental rack 2 and carrying an arm 16, curved 0n the arc of a circle described by the segmental slide 5. This arm is adapted to contact with a push-rod 17, projecting from an alarm-bell 18, secured to the end of the slide 5, and to serve as a stop to limit the movement of the lever 15, as will be referred to again hereinafter.

19 designates a signal-bell secured upon the lever 15 above the arm 16 and provided with a push-bu tton 20, adapted to be operated by a push-rod 21, which extends through an opening 22, formed in the handle 23 of the lever. This rod 21 is depressed by means of a [ingerpiece 24: comprising a bent strip of spring metal secured at its upper end to the upper end of the rod 21 and having a pin projecting from its lower end into a beveled recess formed in the side of the push-rod.

Pressure upon the finger-piece 24 imparts a sufficient downward movement to the rod 21 through the pin 25 to depress the pushbutton 20 and ring the bell. The rod 21 is caused to retract by the slight upward movement of the pin which projects through the bell 19 or by other suitable means when the pressure on the finger-piece is relieved.

The handle 23 is hollow and slotted at one side for the accommodation of the fingerpiece 24. Within the hollowlower end of the handle 23 is arranged means for locking the operating-lever to the segmental rack, comprising a disk 26, Fig. 5, and a dog 27. The disk 26 is formed with a semicircular recess 28 to permit of the passage therethrough of the push-rod 21 and is slotted on both its upper and under sides, as shown at 29 and 30, to receive the dog 27. This dog is in the form of a bell-crank leverfulcrumed upon a crosspin 31, and its upper arm 32 is formed with diverging arms 33 and 34 and a shoulder 35. A coil-spring 36 is seated in the disk 26 below the arm 33, said spring serving to normally hold the catch 37 of the dog in engagement with the teeth of the rack 2.

The peculiar form of the upper end of the bell-crank lever or dog is to prevent the disengagement of the dog except by a device specially designed for the purpose and here shown as a removable pin 38, formed at its lower end with a cup-shaped depression 39 and at its upper end with a head or cap 40. This pin 38 is adapted to be inserted into the hollow handle 23 and forced downward to tilt the bell-crank lever, and this disengages the catch 37 thereof from the rack, the spring 36 thereof acting as the retracting means. Obviously the dog 27 might be weighted instead of provided with the retracting-spring.

Projecting from the lever 15 below the bandle thereof is a spring-arm 41, provided with an indentation 42, adapted to engage a corresponding projection 43 on the rack 2 for the purpose hereinafter explained.

As is well known, the limit of speed of antomobiles, locomobiles, or other motor-vehicles is regulated in cities and towns by municipal laws, anditis therefore desirablein order to comply with such laws that the vehicles be so controlled that the prescribed limit of speed cannot be exceeded. Again, it is desirable on the part of owners of this class of vehicles to place some restriction as to speed upon persons hiring or using the vehicles. A further important desideratum in connection with motor-vehicles is that they should be protected from being tampered with, when left standing, by children or other irresponsible or unauthorized persons. All of these purposes are accomplished by my invention, as will be clear from the following explanation of its operation.

By moving the segmental slide 5 the pushrod 17 of the alarm-bell 18 is arranged with relation to the speed desired or allowed, and when the operating-leveris turned sufficiently to propel the vehicle at the predetermined speed the arm 16 will strike the rod 17, preventing further movement of the lever and ringing the alarm-bell, thus notifying the operator that the li mit of speed has been reached. By means of the locking device shown in Fig. 4 the slide 5 can be locked at any predetermined adjustment, and if the key is not in the possession of the occupant of the vehicle it will be impossible for him to force the vehicle to a higher speed than is permitted by the location of the slide. The spring-arm 41 and its engaging projection 43 are provided as a supplemental. stop device for the lever in case a less speed is permissible at certain points (as at street-crossings) than at others. The engagement of the arm 41 with the projection 43 will restrict the speed to the lesser limit at such points. When the occupant of the vehicle desires to alight and leave it unattended, he withdraws the pin 38 from the handle, thus locking the lever against movement and effectively preventing the operation of the vehicle by unauthorized persons.

The location of the signal-operating fingerpiece on the handle of the lever is an important feature of the invention, as it permits the signal to be sounded by pressure of a finger at the same time that the pin 38 is pressed down by the thumb, thus enabling the lever and signal to be operated at the same time by one hand.

While the construction herein shown and described is practical and operative, it is obvious that many changes and modifications in the details of the mechanism employed might be resorted to without departing from the spirit of the invention, and I would therefore have it understood that I reserve the right to make all such changes, variations, and modifications as may properly fall within the terms and scope of the following claims.
