` FACTORY TRUCK Filed June 6. 1927 Patented Sept. 17, 1929 UNITEDV STATES JOSEPH H. STALEY, OF COLUMBUS, INDIANA.
FACTORY TRUCK Application filed June c, 192,7. serial No. 196,658.
This invention relates to factory trucks,
and particularly to a truck that may be positioned to remain immovable until auxiliary means are employed to permit its being rolled about from one position to another.
The object and advantages of the invention will readily be apparent by the following description with reference being made to the accompanying drawing, in which,
Fig. 1, is a perspective view of the truck ready for being moved about;
Fig. 2, an enlarged fragmentary detail ele vation of the forward end of the truck;
Fig. 3, an enlarged fragmentary detail ele:
vation of the forward end of the truck, similar to Fig. 2, but with the truck in a lowered position;
Fig. 4, an enlarged front elevation of the truck dolly; and
Fig. 5, a vertical elevation through the dolly on the line 5-5 in Fig. 4.
v,Like characters of reference indicate like parts throughout the several views of the drawing. v
The truck proper is formed of the frame or base 10, on which may be carried any style of door orbox-bed (not shown) as may be desired to meet the particular use to which the truck may be put. The frame 10 is supported on a transverse shaft 11 carried by the brackets 12 and 13 back of the center of the frame 10, which shaft 11 carries the wheels 14 and 15.
The forward end of the truck carries the 5 legs 16 and 17 which normally rest on the floor and maintain the frame 10 horizontally in cooperation with the wheels 14 and 15.
Since the legs 16 and 17 bear on the floor,
the truck is held from rolling .or shifting about while being loaded or unloaded.
Secured' to the front cross member 18 of the frame 10 is a casting 19 projecting forwardly which has a conical opening therein from its under side. A pilot pin 20, also conical in shape adapted to it Within the opentongue body 25.
The lower ends of the arms 23 and 24 are extended downwardly to receivetransversely therethrough the axle 26 on the outer ends of which are carried the wheels 27 and 28. Between the two lower ends of the arms 23 and 24 1s a pawl 29 pivotally swung on the axle 26 therebetween. A tongue 30 is secured in the body 25 and by raising and lowering the tongue 30 to rock the body 25 about the axle 26, the arms 23 and 24 are correspondingly rocked, which action causes the post 21 to be raised or lowered, as t-he case may be. The major portion of the post 21 is depended below the supporting shaft 22 so that the post 2 1 .normally tends to remain in a vertical p0- s1t1on as it is raised and lowered.
The lower end of the post 21 has its face 31 upwardly inclined from that lower edge farthest removed from the axle 26, and the length of the post 21 is so made, that, upon lowering the tongue 30 to swing the arms 23 and 24 toward the upper vertical position, the axle 26 will approach the lower end of the post 21, as in going from the position in Fig. 3, to that in Fig. 2, whereupon, the hooked end of the pawl 29 will strike the inclined face 31 of the post 21, slide thereunder, and engage the sharpened edge, as in Fig. 2.
The pawl 29 has an arm 32 projecting therefrom through which is loosely passed a stud 8o 33 having a head on its outer end to limit the Y swing of the arm 32 and hence of the pawl 29, and having its other end secured in the body 25. A spring 34 is carried on the stud 33 to compressively engage between the arm 85 32 andthe body 25 whereby the arm 32.is normally pressed away from the body 25 to throw the pawl 29 to the upper limit of travel as determined by the head on the stud 33. It is to be noted that the back face of the post 21 is undercut at a (Figs. 2 and 3) just above the sharpened edge of the post to permit positive engagement of the pawl 29 with the post 21 so as to prevent any sudden jar to cause the pawlto be disengaged.
A wire 35 is secured to near the outer end of the pawl arm 32 and passed up through an opening 36 into the tongue 30 which is tubular, and the wire 35 is carried on up through the tongue to a handle 37 extended outward- 100 the floor, and it is desired to move the truck,
the tongue 30 audits associated elements comprising what is commonly termed a dolly is brought up to the front end and the tongue 30 is raised with the pawl 29 disengaged from the post 21, and the post 21`is positioned under 4the casting 19 so that, upon lowering the tongue 30 slightly, the pilot pin 2O is entered into the passage or seat in the @casting 19. A collar 39 is formed at the base of the pin 2() on the post 21 to contact the under side of the lcasting 19 to limit the entrance of the pin 2O therein so that the pin 20 may be free to revolve within the seat.
The tongue 30 is then lowered as in Fig. 2, to raise the post 21, fulcruming over the axle 26, to in turn raise the truck frame to carry the legs 16 andx 17 away from and above the floor. The pawl 29 will then engage over the end of the post 21 and prevent the tongue 30 from rising. The truck frame is then entirely supported by the two rear wheels 14 and 15 and the two front wheels'27 and 28, and is easily moved about by pulling the tongue 30. As the post 21 is pivotally entered by the pin 20 in the casting 19, the truck may be guided about by turning the tongue 30 to swing the front wheels 27 and 28 as desired.
I claim:
1. Ina truck having a leg support, a coupling member on the truck, a pair of auxiliary wheels, a pair of arms fulcrumed on the axis of the wheels, a post transversely pivoted to and hanging downwardly between the arms, the upper end of said post being formed to engage in said coupling member whereby the post is maintained in a vertical position, means for rocking said arms about said axis to cause the axis to travel toward the post, and means to engage the lower end of the post.
2. In a dolly and truck, a coupling member on the truck, a post detachably engaging in the coupling member whereby the post is pivotally maintained in a vertical position, a wheel, an armlfulcrumed 0n the axis of the wheel, said arm being pivoted by its outer end to near the upper end of the post, a tongue adapted to rock the arm about the axis of the wheel to cause the wheel axis to travel toward the post, and `means cooperating between said tongue and said post to secure the arm in -a fixed relation to the post.
3. In a truck having wheels at one end and a leg support at the other end, a coupling member at the leg end, a pair of auxiliary wheels, an axle for said wheels, an arm fulcrumed on the axis of the wheels, a post pivotally hanging from the arm, a bearing formed on the upper end of the post to be pilot pin, of a truck frame, wheels at the rear of the frame, legs 4at the front of the frame and a coupling at the front of the frame comprising a forwardly projecting member having an underside tapering socket receiving' the tanering pilot pin.
5. The combination with a dolly and a post supported by the dolly on a transverse pivot above its middle, said post having a conical pilot pin and a collar forming an extended base for the pilot pin, of a truck frame, wheels at the rear of the frame, legs at the front of the frame and a coupling at the front of the frame comprising a forwardly projecting member having an underside taperin socket receiving the tapering pilot pin and caring upon the collar ofthe pin.
In testimony whereof I aflix my signature.
JOSEPH H. STALEY.
