Description
UNITED STATES PATENT OFFICE.
HERBERT G. LA SOB, OF LOS ANGELES, CALIFORNIA.
INKING-ROLL TRUCK.
Application filed July 21,
To all whom it may concern.
Be it known that I, HERBERT G. LA Son, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented a new and useful Inking-Roll Truck, of which the following is a specification.
My invention relates to adjustable inking roll trucks for printing. presses and more particularly to that type known to the trade as expansion roller trucks in which various forms of expansion devices are utilized for varying the diameter of the truck roller to compensate for variations in the diameter of the inking roll and for regulating the degree of contact pressure of the inking roll against the type form.
The object of my invention is to provlde a truck roller having an expansible peripheral tire laterally confined upon a split ring and a pair of opposed cone members cooperating to expand the split ring and peripheral tire.
Another object is to provide a split r ng type of truck roller in which the split ring functions to frictionally lock the parts in adjusted position.
A further object is to provide a simple and durable structure which can be cheaply manufactured.
The various features of construction and arrangement of parts employed in the fulfilment of these objects will be more fully understood from the following description and accompanying drawings illustrating a preferred embodiment of the invention, corresponding reference characters representing corresponding parts throughout the several views, of which Figure 1 is a side elevation of one end of an inking roll showing the truck roller applied thereto.
Fig. 2 is a similar elevation showing the truck roller in section.
Fig. 3 is a detail perspective view of the stationary cone member.
Fig. 4 is a detail perspective view of the split ring tire supporting member.
Fig. 5 is a detail perspective view of the spiral tire, and
Fig. 6 is a detail perspective View of the adjustable cone member.
The drawings show only one end of the inking roll and one truck roller, it being Specification of Letters Patent.
Patented May 31, 1921.
1919. Serial No. 312,317.
obvious that a duplicate truck roller may be provided for the opposite end of the roll.
As shown, the truck comprises a cone member 1, keyed or otherwise secured on the shaft 2 of the inking roll 3 and provided with an elongated screw threaded hub 4:. An opposing adjustable cone member 5 is carried upon the hub 4L and has a screwthreaded engagement therewith, both cone members being provided with suitable re cesses 6 to accommodate an adjusting wrench or tool of any preferred form.
Intermediate the two cone members and supported upon the conical surfaces thereof, is a split ring 7 having marginal flanges 8-8. Between the flanges 88 is positioned a coiled expansible tire or tread 9 which is made of spring metal and has a normal tendency to contract.
In use, by turning the cone member 5, the conical surfaces of both cone members will cooperate to expand the split ring and coiled tire or allow them to contract, depending upon the direction the cone member 5 is turned, thereby varying the diameter of the truck roller.
It has been found that in a split ring structure, as herein employed, where, during the expanding of the ring it is not positively confined to an absolute concentric form, it will first flex at the side opposite the split and that adjacent the split it will more nearly retain its normal shape. This, in effect, provides a three point contact of the split ring against the conical surfaces of the two cone members causing the sharp edges adjacent the split to impinge against said surfaces to frictionally lock the parts in adjusted position.
This structure is well adapted to fulfil all the requirements of an efficient truck and at the same time is strong and durable and consisting of only four parts it is cheap to manufacture.
i Vhile well adapted to fulfil the objects primarily stated, the particular construction here shown and described is of course susceptible of modifications and the invention is not necessarily to be considered as limited in this regard.
I claim:
1. A truck for inking rolls comprising a cone member having a screw-threaded hub, an opposing cone member screw-threaded for adjustment upon said hub, a split inherently contractile ring supported upon the peripheral cone surfaces of the cone members, and an expansible tire embracing the split ring.
2. A truck for inking rolls comprising a pair of cone members having opposed conical surfaces, one of said members being adjustably supported upon the other, a split inherently contractile ring intermediate the cone members engaged and supported by said conical surfaces and an eXpansible tire embracing the split ring.
3. A truck for inking rolls comprising a pair of opposed cone members, one having a screw-threaded hub and the other having a cooperating screw-threaded bore provid-v ing a relative lateral adjustment, a split inherently contractile ring supported by and engaged upon opposite sides by the respective opposed cone members, and an expansible tire embracing the split ring.
4. A truck for inking rolls comprising a split inherently contractile ring, an expansible tire embracing said ring and a pair of interengaging, relatively adjustable opposed expansion members engaging opposite edges of the split ring.
5. A truck for inking rolls comprising a split inherently contractile ring having outwardly flanged peripheral edges, an expansible tire embracing the ring intermediate its flanged edges, and a pair of interengaging, relatively opposed expansion members engaging opposite edges of the split ring.
6. A truck for inking rolls comprising a pair of relatively adjustable opposed cone members, a split inherently contractile ring engaged upon opposite sides by the cone members and an expansible tire embracing the split ring, said tire being formed of flat spring metal closely Woimd in spiral formation to provide a continuous tire surface.
7 A truck for inking rolls comprising a split inherently contractile ring, an expansible tire embracing said ring and a pair of relatively adjustable opposed expansion members engaging opposite edges of the split ring.
Signed at Los Angeles, California, this 15th day of July, 1919.
