STATES FATENT OFFlCiE.
OSCAR- STYLES PENN, OF LONDUN, ENGLAND, ASSIG-NOR T0 ROADLESS TRACTION LIMITED, OF HOUNSLOXV, ENGLAND.
ENDLESS TRACE. FOR VEHICLES.
application filed March 6,
Be it known that 1, Oscar: S'rrLns PENN, a subject oi the King oi? Great Britain, residing at 59 il est Side, li andsworth Common, London, England, have invented new and useful linproven'ients in Endless T racks for Vehicles, of which the following is a specification.
"lhis inven'ion relates to endless tracks for whole or 1 t ack vehicles and the preferred type or tr k to which the invention is applied CODES-{S oi track shoes which are connected to ier by links having male and teinaie coupled to her by a pin and in \vhich limited universal movement is allowed between adjactent links and also in which the links are so formed that spaces are provided for the reception of lubricant and in this preferred form the teeth by which the track is driven may be centrally arranged at the top of the links.
According to this invention the paths upon which the weight carrying rollers run are arranged on each side of the teeth and above the joint pins. The joint pins are extended on each side oi: the joint and pass through holes in lugs carried near the edges of. one link and also preferably extend beyond these lugs into holes in lugs on the adjacent link, the diameters oi' the first mentioned holes being greater than the diametcrs o'l' the parts of the pin passing through them to allow oi movement. between adjacent linl's.
According to this invention. also the track shoes may be carried by the joint pins, the shoes being secured to or made in one piece with the frame having two bearings through which the pin passes. The angle through which a shoe can turn relatively to its pin is limited by the formation of the underside oi? the link and the shoes may carry cushions which engage with the underside of the links. In this case the paths ilior the weight carrying rollers are carried by the links and form bridges between the rocking shoes.
The accompanying drawings illustrate endless tracks made in accordance with this invention. Figure l is a plan partly in section of three links assembled together. Figure 2 is a longitudinal section and Figure 5 is a transverse section of a link. ure 4 is atransve so section of a link joint as in Figure l in which the track shoe is lees. Serial No. 13,611.
carried by the joint pin and Figure 5 is a similar view in Figure 2 showing the track shoe as in Figure l.
(a are the links having paths 5 arranged on each side oi the teeth 0 above the joint pins 5. On each joint pin (Z is a bush 6 having a spherical portion housed in a spherical seating f, in the male end 9 of the link. it are housing rings provided to prevent the entrance of dirt. The joint pins (5 pass through holes in lugs j on the same end oi? the link carrying the male end 5 and also into holes in lugs ll; on the adjacent link, the diinneters oi? the holes in the lugs being greater than the diameters of the parts of the pins passing through them to allow or movement between adjacent links.
In some cases the lugs 70 may be dispensed with, the pins cl being made shorter than shown in the drawings. The links a are hollow to form a reservoir for lubricant which passes to the pins (Z through holes Z.
Referring especially to Figures eland. 5, the track shoes m are secured to frames at having two bearings 0 through which the pin (Z passes. The angle through which the shoe can turn is limited by cushions p which engage with the underside of the links; the cushions may be carried on the track shoes m, as shown or upon the links. The'paths Z) for the weight carrying rollers "form in this case bridges between. the rocking track shoes m.
What I claim is 1. A link joint comprising a pin connectlink having a central lug on one end, av
spherical seating in the lug, a spherical member supported by the pin and adapted to turn in the seating, two other lugs on the same end, two lugs on the other end intermediate the lugs on the first mentioned end, and holes adapted to receive the pin in all the lugs, the diameters oi the holes in the iirst mentioned. two lugs being greater than the diameters of the parts oi? the pin passing through them.
2. A link joint comprising a pin connecting together the adjacent link ends, each link having a central lug on one end, a spherical seating in the lug, a spherical member supported by the pin and adapted to turn in the seating, two other lugs on intermediate the lugs on the first mentioned end, and holes adapted to receive the pin in all the lugs, the diameters of the holes in the first mentioned two lugs being greater than the diameters of the parts of the pin passing through them.
3. A link joint comprising a pin connecting together the adjacent link ends, each link having a central log on one end, a spherical seating in the log, a spherical member supported by the pin and adapted to turn in the seating, two other lugs on the same end, two lugs on the other end intermediate the lugs on the first mentioned end, holes adapted to receive the pin in all the lugs, the diameters of the holes in the first mentioned two lugs being greater than the diameters of the parts of the pin passing through them, a tooth on the upper partof the link and paths for the weight carrying rollers on each side of the tooth and above the pin.
4. A link joint comprising a pin connect ing together the adjacent link ends, each link having a central log on one end, a spherical seating in the lug, a spherical member supported by the pin and adapted to turn in the seating, two other lugs on the same end, ttonr lugs on the other end intermediate the lugs on the first mentioned end, holes adapted to receive the pin in all the logs, the dizn'nelers of the holes in the two lugs being greater than the drain eters of the parts ot the pin passing through them, a tooth on the upper part oi the link and paths for the weight carrying rollers on each side of the tooth and above the pin.
A link joint comprising a pin connectether the adjacent link ends, each link a central log on one end, a spherical seating in the lug, a spherical member supported by the pin and adapted to turn in the seating, two other lugs on the same end, two logs on the other end intermediate the logs on the first mentioned end, holes adapted to receive the pin in all the logs, the diameters of the holes in the first men tioned two legs being greater than the diameters of the parts of the pin passing through them, and track shoes carried by the pins.
6. A link joint comprising a pin connecting together the adjacent link ends, each link having a central log on one end, a spherical seating in the lug, a spherical member supported by the pin and adapted toturn in the seating, two other lugs on the same end, tour lugs on the other end intermediate the logs on the first mentioned end, holes adapted to receive the pin in all the logs, the diameters of the holes in the two legs being greater than the diameters of the parts ot the pin passing through them, and track shoes carried by the pins.
7. A link joint comprising a pin connecting together the adjacent link ends, each link having a central log on one end, a spherical seating in the log, a bush with a spherical portion adapted to turn in the seating, two other lugs on the same end, two logs on the other end intermediate the lugs on the first mentioned end, and holes in the bush and logs through which the pin passes, the diameters of the holes in the logs of the first mentioned end being greater than the diameters or? the parts oi the pin passing through them.
In testimony that I claim the foregoing as my invention I have signed my name this 12 day of February 1925.
