Be it known that I, CLIFFORD A. OwENs, a citizen of the United States of America, re-

siding at'Owens, in the vcounty of Marion positive and particularly simple means for insuring normal and continuous operation of the Bissel pin structure with substantially no wear of such structure and its connected parts. It also results in important safety measures in that the locomotive frame is relieved from all damaging shocks or jars tov which it might be subject from the front truck structure.

The Bissel pin of a'locomotive is the com-A mon name used for the vertically reciprocable plug which is connected with the front truck structure of a locomotivew The fronttruck of a locomotive is mainly for guiding purposes and it is, therefore, free to move up and down as it carries none of the weight of the locomotive proper. The Bissel pin is connected to and controlled by the .front t'ruck structure and as the truck move up land down, due to irre ularities in the track and other means, the issel pin is likewise designed to freely move up and'down within a bearing which is usually formed by, and integral with, the front frame of the locomotlve. This Bissel pin andfront truck structure is a very important and vital part of the balancing and equaling system of a locomotive, and if for any reason the Bissel pin sticks in its bearing all of the vibrations and shocks of the front truck will be d1- rectly absorbed by the locomotive frame instead of being absorbed by the standard spring structure. y

In the past, it has been the usual practlce to provide a plain vertical bearing in the front deck casting of a locomotive for the reception ofthe Bissel-pin and to` depend entirely upon th'e play between the pin and its bearing to give the necessa freedom of movement to such pin. As a direct result of the use of saidstructure and the lack of proper protection for the Bissel pin, all locomotives have been sub] ect to an unneces- 1923. serial No. 637,254.

sary amount of repair and loss of running time. The front trucks of a locomotive are subject to an innumerable number of shocks or bumps during a single run and it is obvious that the trucks may easily belsubjected to hundreds of severe jolts in passing over a single mile of track. It `will be obvious, therefore, that unless some protective means 1 is placed between the Bissel pin andits bearing the excessive friction between the reciprocating Bissel pin and its bearing will soon cause uneven wearing and subsequent galling or sticking of the Bissel pin in its bearing.

Furthermore, the space' between the Bissel pin and the bearing has always been constantly filled with cinders and dirt, either from the smoke stack or the clean. out which is located directly above the Bissel pin, which also has caused excessive grinding and wearing of the parts. This sticking and excessive wearingof the Bissel pin and its bearing not only. necessitates frequent replacement but it directly affects the general maintenance of the entire locomotive and necessitates frequent repairing of the frame itself.

My invention primarily contemplates the provision of means which will positively insure freedom of movement of the Bissel pin structure at all times withv .substantially no wear on the bearing surfaces, and which means is of such construction that it may be quickly and easily applied to any locomotive provided with a Bissel pin with no change in the structure thereof. This is accomplished by means of a very simple and compact structure which comprises a specially designed casing for protecting the Bissel pin and its bearing from alldust and dirt and lubricating means carried by such casing for insuring continuous lubrication -of the Bissel pin.

' More specifically, I have found that although the. most damaging and Vdangerous wear and shock to locomotive parts' is that upon the frame, equalizer and spring structure, yet the normal and smooth operation of suc'h structure is directly dependent upon the'smooth and free operation of the Bissel pin. Therefore, I have provided a protect- `ive outer casing for the Bissel pin, which may be secured to any locomotive bearing casting, and a cover for such casing to completely protect the pin from dust' and d irt or will be brought out by the claims appended hereto. rlhe various objects of my invention are attained by the structure illustrated in the drawings wherein similar characters of reference designate corresponding parts and wherein- Figure 1 is a diagrammatic illustration of 4a locomotive and Bissel .pin structure with my device applied thereto and showing the manner of connecting this Bissel pin structure with the equalizer' structure ofthe locomotive.

Figure 2 is an enlarged, vertical, sectional fragmentary view of the Bissel pin structure and-its connected partsand showing in detail the manner of protecting and lubricat- `ing the Bissel pin and its supporting bearing.

Figure 3 .is a diagrammatic fragmentary View of a locomotive front truck structure, a Bissel pin provided with my lubricating and protecting device, and an equalizer structure connecting with said Bisselpin.

lln the drawings, and with particular reterence to Figure 1, the locomotive frame 1s shown as at 1 and the front truck structure which serves principally as a guide for this frame is shown as at 2. lt will be obvious Athat both the locomotive frame structure and the front truck structure can only be shown conventionally as they may take any form consistent with the diterent standard types of locomotives.

The front truck structure 2 usually consists of standard small truck wheels and their connecting axle 3. Disposed between the truck wheels and designed to support the Bissel pin 4 is the truck support 5. This truck support 5 is preferably provided with a recess 6 for the reception 'of the lower end of the Bissel pin, and it is also provided' with an aperture 7 which is designed to receive a centering pin 8. The centering pin 8 is designed to ass through an aperture in the base of the Blsseln p in. llt will be obvious that this centering pin will permit of vertical reciprocatio'n'of the truck support 5 and Bissel pin 4 and at the same time keep these parts in vertical alignment.

'llhe upper end of the Bissel pin 4 is de signed to pass through and be supported by a bearing 9 which is preferably integra ly formedin the front truck casting 10 of the locomotive. 'lfhua as the truck structure 5E moves up and down or isvibrated by ii regularities in the track9 this up and down movement of the truck structure will be transmitted to the Bissel pin l which in :7

turn will reciprocate within the supporting bearing 9... This up and down movement of the truck and Bissell pin structure is prelierably absorbed by means of the spring and equalizing structure oi the locomotive. The equalizing structure comprises a bar 1l, one end 12 of which is designed to be connected to the Bissel pin by means of a'suitable-slot 139 as best shown in Figure 2. As shown, this end 19. of the equalizing bar may be directly supported by the top of the centering pin 8. rllhe equalizer bar is ulcrumed as at lllby means of a suitable center pin and center pin bearing.` As shown at Figure 1 it is customary to make this center pin bearing adjustable to take Careof any desired adjustment in the equalizing or balancing system of the locomotive.

yllhe spring structure 15, which comprises a series of springs and connecting links ar- .ranged on eaeh side or" the locomotive, forms a part of the balancin D system of the' locomotive and is connectel to the rear end 16 of the equalizer bar l1 by a suitable connecting bar or link 17. lt will be obvious that this equalizing bar and spring structure not only serves as a means for absorbing the shocks or up and down movement of the truck and Bissel pin structure but that the Bissel pin structure in turn forms an important part of this balancing structure in that itis absolutely necessary that the Bissel pin should be free to move upand down in order to preserve the proper balancing of the locomotive.

lin order to insure positive up and down movement of the truck and Bissel pin structure Il have provided the bearing 9 with a circular casing 18. This casing is preferably designed to be welded on to the bearing casting 9 and is of such a size and shape as to provide a space 19 between the surface of the protruding Bissel pin and the casing. rllhe space 19 is ot such a size that it will permit of the packing of a suitable quantity of waste or other lubricant absorbing material around the Bissel pin. The

top of the casing 18 is provided with a cover 20 which is also 'provided with a suitable handle-21.1201' the easy removal ol this cover. ll have also provided the cover 29 with a suitable oil hole 22 to permit oiling ot the waste andBissel pin without remov ing the cover. llt will thus be seen that, as

the Bissel pin is moved up and down by any vibration ot the truck structure, the sides of the Bissel pin will be continuously lubricated by the oil soaked waste contained in the casing 18. As the casing 18 and cover 2 0 also preclude the entrance oit any cinders lits bearing.' .f

In they normal operation of the front i truck and fBissel pin structure, the truck will bemoved upward by any irregularity in the track and this upward movement Will be transmitted to the Bissel pin 4. If this Bissel pin 4 is free to move Within its bearing 9 thel locomotive frame Will be relieved of substantiallyg'all jar or vibration and instead this vibration will be transmitted through the equalizer bar l1 and will be absorbed by the standard spring structure 15 ofthe locomotive. If for any reason the Bissel pin 4 would stick 'in its bearing-9, duel tothe lack of lubrication or the entrance of cinders or other foreign material, all the v vibration and shocks of the truck structure 2 would be directly transmitted to thevlocopreferred shape shown it will be seen that motive frame instead of being absorbed by the spring structure. Bissel pin would not only seriously damage the locomotive frame but it Would also tend to render less effective the important balancing structure 0f the locomotive.

It will be understood that the lubricating land protecting casing 18 and cover 20 may be of any suitable shape and size butin the This sticking of the dom of move'nri'entA and substantially Ano Wear.

It will be apparent that I have provided l an extremely simple but positive lubricating and protecting device for the Bissel pin that may be easily secured to the frameor bearing casting of the locomotive and Which will be effective to lubricate and protect the Bissel pin under all conditions of operation. It will also be obvious that by lubricating and protecting this Bissel pin and' its supporting bearing I am able to .obtain practically continuous service from a structure that has hitherto been frequently subject bo repair and replacement. Furthermore, by 'the use of my invention, I have been-able to materially reduce the Wear on the front deck casting of the locomotive, on the center pin and center pin bearing, of the equalizer, on the hanger bearing at the back end of the equalizer, on the engine t-ruck cradle at the point Where the Bisselpin comes in contact with the bearing on the cradle,ron the spring rig all lthe Way through and on all parts of the locomotive in general.

I-Iaving thus described my invention, what I claim is:

1. In combination with a locomotive truck structure, of a Bissel pin, abearing, means carried by the locomotive for protecting the Bissel pin and bearing from cinders or any other foreign material and means for lubricating said pin.

2. Locomotive Bissel pin structure comprising means enclosing'the top of the Bissel pin for lubricating and protecting the same. In testimony whereof I hereby affix my signature.

CLIFFORD A. OWENS.
