' 3 Claims.
The present invention relates to new and useful improvements in motor driven skates and has for its primary object to provide control means for the motor in which said control means embodies levers attached to a belt secured to the waist of a person andproviding flexible cables leading from the levers to the several mechanisms of the motor, such: as the switch, timer, clutch and gear shift, for controllingthe operation of the motor.
A further object is to provide an attachment of this character of simple and practical construction, which is efficient and reliable in performance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the' details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which Figure 1 is a front elevational view showing the belt and control levers attached thereto,
Figure 2 is a rear elevational view showing the cables leading along the legs of a person to the motors at the rear ends of the skates,
Figure 3 is a vertical sectional view through the housing of the control lever of the timer and clutch devices, 7
Figure 4 is a front elevational view of the housing for the gear shift control lever,
Figure 5 is a vertical sectional view through the housing for the switch control lever,
Figure 6 is a transverse sectional view taken substantially on a line 6-6 of Figure 5, and
Figure '7 is a vertical sectional view through the housingof the control lever of the gear shift mechanism.
Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred form of the invention, the numeral 5 designates a motor driven ice skate, of which one is adapted for attaching to each foot of a wearer and supported on the rear end of each skate is a motor 6, preferably in the form of an internal combustion engine.
Secured around the waist of the wearer is a belt 1 to the front side of which are secured a plurality of vertical tubes designated at 8, 9, l0 and II, each of the tubes or housings having ears l2 projecting from opposite sides thereof for securing to the belt.
The housing 8 is provided adjacent its upper end with a vertical slot l3 through which a handle or lever l4 projects forwardly of the housing, 7
the inner end of the leverbeing attached to a head 15 slidably mounted in the housing and to the lower end of which is attached a pair of flexible wires l6 and I1, leading to the switches (not shown) of the respective motors 6.
The housings 9- and I0 are'of identical construction and contain the control mechanism shown in detail in Figure 3 of the drawings. Each mechanism includesagear l8 journalled on a pin l9 extending transversely at an intermediate portion of the housing and at diametrically opposite sides of the gear I8 are racks 20 and 2|, the rack 20 being positioned at the front of the housing immediately behind the vertically extending slot 22 formed adjacent the upper end thereof, while the rack 2| is positioned at the rear of the housing, both of the racks being operatively engaged with the gear as shown in Figure 3 of the drawings.
A lever 23 projects from the upper end of the rack 20 outwardly through the slot 22 and a dog 24 is pivoted as at 25 to the upper portion of the rack 20 for engaging the vertically spaced notches 26 formed in the outer surface of the housing adjacent'the slot 22. A coil spring 21 positioned under the lever 23 engages the dog 24 for yieldably urging the same in engagement with the notches. To the lower end of the rack 20 is attached a pair of flexible cables 28 and to the lower end of the rack 2i is attached a similar pair of cables 29.
The cables 28 and 29 of the housing 9 extend to the timing mechanism (not shown) of the respective engines 6 whereas the cables of the housing I0 extend to the clutch mechanism (not shown) also forming part of the control mechanism of the engine. It will be apparent that upon the movement of the rack 20 in one direction that the rack 2| will be'moved in an opposite direction to thus control the opposite movement of the timer and clutch mechanisms in a manner as will be apparent. I
The housing II is provided with a vertically extending slot 30 adjacent its upper end through which projects the lever 3| which is formed on a.
head 32 slidably mounted in the housing. Also projecting outwardly through the slot 30 is a dog 33 which is pivoted as at 34 to the head, the dog being adapted for engaging the vertically spaced notches 35 formed on the outer surface of the housing adjacent the notch. A coil spring 36 is positioned between the lever 3| and the dog 33 to yieldably urge the dog into engaged position.
A pair of flexible cables 31 are attached to the lower end of the head 32 and extend downwardly through the lower end of the housing for connection with the gear shift mechanism, (not shown) of each of the engines 6.
It will be understood that the switch, timing mechanism, clutch and gear shift mechanisms of the engine 6 are of conventional construction and adapted to be, controlled by the flexible cables leading from the respective levers for opening and closing the switch, advancing or retarding the timer, for moving the clutch into and out of engagement and also for shifting the gears into high or low speed. In view of the fact that such mechanisms are well known in the art it is not deemed necessary to include a detailed dis closure of the same in the present application.
The several sets of cables leading from the' levers of the control devices may be slidably mounted through guides 38 attached to the pants legs 39 of the wearer at the inner side thereof,
end of the housing for attaching to a part of the motor, and a manually actuated device attached to the member and projecting from the slot in the housing, said slot and manually operated device retaining the member against removal from the housing.
2. A control attachment for motor driven skates comprising a belt adapted for attaching to a person, a tubular housing attached to the belt, a member slidably mounted in the housing, cables attached to the member and extending from the housing for attaching to a part of the motor, said housing having a slot therein, a
manually actuated device attached to the member and projecting outwardly through the slot l and means carried by the manually actuated device and engageable with the housing to secure themernber in a predetermined position, said slot and manually actuated device retaining the member against removal from the housing.
,3. A- control attachment for motor driven skates, comprising a belt adapted for attaching to a person, a housing attached to the belt, a gear journalled in the housing, a pair of racks at diametrically opposite sides of the gear and engaged therewith for opposite movement ofthe racks, cables attached to each rack and extending vfrom the housing for attaching to apart of e the motor and a manipulating lever attached to one of the racks for oppositely actuating the cables. 7
