AUGUST J. DINKLAGE, OF EAST ORANGE, NEW JERSEY.

Be it known that I, AUGUST J. DINK- LAGE, a citizen of the United States. and resident of East Orange, county of Essex, State of New. Jersey, have invented a certain new and usefullmprovement in Anti creeping Devices for following is a specification.

My invention relates to anti-creeping devices and more particularly to such devices as are used for preventing or arresting the creeping tendency of railroad rails. My improvement has for its object to increase the efficiency of such devices by so con'ib ning illustration the line 44 of Fig. 5 Fig.5 is a plan. view the coiiperating parts thereof with the rail as to prevent unintentional displacement thereof for instance by the road ballast, ice and snow in Winter or -from any other cause.

.Afurther object of my invention is to simplify the construction and arrangement of the individual elements without affecting the efiiciency of the device as a whole. .Qther objects will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims Referenceis tobe had to the accompanying drawings in which for the purposes of several examples of my improvement and in which Figure v1 is a sectional view on the line 11 of Fig. 2 of one form of my' improved device applied to a rail; Fig. 2 is a plan view thereof partly in section; Fig. 3 is a side elevation thereof; Fig. 3 isan end view of the wedge included in Fig. 4 ing another form of my invention taken on thereof partly in section; Fig. 6'is a side eleclined in the usual Way.

the illustration represents a railroad rail further includes the usual head 17 and may be otherwise constructed in any usual manner and include any other i atures which may be common to rails of the type in question. My improved device'as shown. in the figures referred to, comprises a clamp 18 having a rail engaging 19 which in practice extends around one edge of the base 16 and into contact with an upper inclined surface of said base, the illustration showing said jaw in contact withi- 'the surface 16. Preferably in rather cldse proximity to said jaw 19 the clamp is formed with a projection 20 which in active use engages the lower surface of saidfraii base 16 and togetherwith the jaw 19 forms a space or recess 21 for the accomnie'bdation of a portion of the rail base as showniin Fig. 1. The clamp 18 is further constructed with a member 22 which terminates in a jaw 23. the member 22. inclining downwardly from the projection 20 relatively to tile base 15 when the device is in use while t e jaw 23 extends around the opposite ed e ofsaid base and over the surface 16 thereof when the member 22 is spaced'from he edge of said rail base as shown in Fig! 1. In the form being described a wedge 24 is located between the surface. 16? of the rail base 16 and the jaw which in practice rests upon said surface 16 in frictional engagement therewith as illustrated in Fig.1, said wedge being forced up on-said surface 16 between the jaw 23 and the rail base 16 in a direction toward the web 15. This movement of the wedge will force the jaw 23 in a direction away from the surface 16 so that the member 22 will act in the nature of a lever with the projection 20 as a fulcrum whereby the jaw 19 and the projection 20 itself are forced into closer gripping engagement with the surface 16 and the lower surface of the rail respectively.

In the preferred arrangement some means is rovided for preventing the wedge 25 from as illus- 23 and is formed with proximity to and pre erably in actual contact with a tie 27, the arrangement being I such that the clamp 18 will be held by said appreciable movement in tie 27 against any the direction in which the rail tends to creep.

The force exerted by said rail as it tendstocreep from any cause will be communicated to the wedge 24 owing to the frictional engagement'between the surface 25 of said wedge 24 and the surface 16 of the rail base '16. This force tends to carry the wedge 24 along with the rail in the direction of creep or in other words tendsdto force said wed in this direction is 26 or their equivalents, said force, through the coiiperation of the latter with the jaw 23 operation to overcome a will be converted into a force whereby said Wedge 24 is caused to positively arrest the creeping tendency of said rail. v

The force above mentionedbeing exerted upon or near one end of the anti-creeping device will also tend to mov'e it in a horizontal plane or to skew it relatively to the base 16 and will thus add to the gripping effect of said device upon the rail base.

will be the resistance interposed to the creep of the rail. At the same time it will. be apparent that forces of lesser degree will similarly bring the parts of the device into coy creep in an efficient manner.

It will of course be understood that the parts are so proportionedand arranged that the movement of the wedge 24 toward the web 15 is never sufiicient to completely disengage said wedge from the jaw 23 in this direction. In combining this form of'iny improvement with the rail the wedge 24 may first be placed upon the surface 16" after which the jaw 23 of the clamp is placed over said surface and in loose connection with said wedge. .The clamp is then moved toward the left in Fig. 1 relatively as the wedge 24 and rail base 16 a sufficient disuntil the jaw 19 is in position in which the with the rail and that whereby the desired ge 24 from beneath the jaw 23. V I

f plished. may be followed.

As the separation of the wedge 24 and j aw prevented by the flanges 'erably lies and a will be evident that",

' base be gripped by the improved anti-creeping device and the greater tends to-creep. The wedge 24 igsoaoaa tunes to permit the jaw 19 tobe raised and the recess 21 brought into registry with the ed e of said. rail base. The clamp is then in ividually moved back toward the right engagement with the after which the wedge 24 may be on the surface 16* to an initial parts are firmly and securely'clamped upon the rail base. It will of course be understood that the combination of the anti-creeping device with the rail takes'place at a suitable point to bring theclamp'18 into' close proximity and preferably into actual engagement with a tie 27 as hereinbeforementioned; It will further be apparent that the above is only an surface 16 driven u example of how the device may be combined any other proceeding results are accom- Figs. 4, 5, 6 and 7, the projection 20 is omitted in the clam'p 18 and the member .22 thereof, is substantially straight throughout and in practice prefsurface engagement with" the lower surface of the rail-base 16 as shown in Fig. 4; The clamp18 also. includes a rail-engaging j aw 19similar to the jaw 19 and which likewise engages thesurface 16 of said base 16', said jaw forming a continuation of the member 22 and forming therewith a recess 21 for the accommodation of the railbase as the Q e end the clamp 18". when in use extends a out the opposite edge of the rail-base 16 In the form shown in previous form. At its oppopreferably in spaced relation thereto and terminates in a jaw 23 which extends over the surface 16 of said base at a distance therefrom in substantially the same way as does the jaw 23 of the form first described. Thelower surface of the jaw 23 is inclined downwardly to form a wedging surface 28 and is cut away for a distance inwardly from its free end to form a wedging surface 29 also inclined downwardly, both surfaces 28 and 29 'being member 22 and transversely to the major axis of said clamp as shown in Fig. 6. This construction furt er provides a shoulder 30 located at a distance from the end of the jaw 23", which shoulder 30 is preferably in clined horizontally relat vely to the web 15 as shown in Fig. 5. When opcrativelv combined with the rail the clamp 18 as in the form previously described is also in close proximity to and preferably in actual engagemcnt with a'tie 27 the arrangement in this instance. being also such that the clamp 18 is held by said tie 27 against any material movement in the direction in which the rail is provided similar to the with an inclined surface 25 surface 25 and likewise resting upon the surfaceflti? of the rail-base 16 in frictional'em gagement therewith as illustrated in Fig.

inclined relatively to the joined by a verticalsurface V clined horizontally relatively tothe majoraaeaoaa In the form now bein described the wedge 24: is' further provided with horizontal sur-' faces 31 and 32 located in different horizontal planes I and inclined downwardly toward the one end of the wedge as shown in Fig.6, the'surface' 31 and 32 being 33 which is int shaped to make this arrangement possible.

In th e preferred arrangement the surfaces 28 and 29 are inclined at angles which correspond substantially to the inclination .of

the surfaces 31 and 32, while the angle of inclination ofthe shoulder corresponds approximately to that of the surface 33. If

' cases also serving desired the wedge 24* maybe provided, at

itsllarge end with ahead 34 or similar-de- 30F vice adaptedto receive the blows of a hammer or other implement which may be .used to drive the wedge. into its initial operative position, said head or the like in extreme to prevent the wedge-from being completely forced from beneath the jaw 23. v

In the operation of this form of my im provement the creeping tendency .of the rail by reason of the frictional engagement jaw surfaces 28 and 29 and 25 of' the wedge 24* "This will bring about a between the surfaces 16* of the rail base will tend to carry Idirection of creep. movement of said wedge relatively to and transversely to the jaw 23 and through the cotiperation of the the latter along in the faces 31 and 32 will exert a lifting force on said jaw '23 which is resisted through the cooperation of the clamp member 22 and lower surface of the rail base 16 as is clearly shown in Fig. 6. In consequence of this. action the wedge 2d will be more firmly jammed -1n between the jaw 23 and the grip of the surface 25 upon the surface 16 and the rail base,

increased, whereby a resistance to the-creeping tendency of the rail is setup.

;:;as'wil1- be clearly-apparent. At the same time; owing .tothe fact that the wedge 24* is ID. engagement with the web 15, the abo e' movement of thewedge will cause the vert1-' {al sur'fi ce 33 thereof to exert a wedging ion on 'the shoulder 30. In consequence this cooperation .of the surface 33 and shoulder. 30,- a force will be exerted upon tending tomove it toward the 118, a force tending to fact that the clamp 18 other. Way whereby desired. The jaw 23" with the wedge sur-- the surfaces 28" surfaces 31 and 32 33 being inclined horizontally 22 upon the lower surface of the rail base 16 to be increased as will be readily apparent. In addition, owing to the fact that the forces due to the creeping tendency of the rail are exerted at or near one end of the clamp skew the latter relbase will also be exerted atively to said my improvement. 'Even in this form of though this skewing tendency, owing to the is in engagement wlth a tie 27, may produce no perceptible actual movement of the clamp in the indi :cated manner relatively to the rail base, the

in resistin the creeping of the rail. Thelatter, in t is form, is theref oreralso lirmly and securely held against any material movement in the-direction of its length. The arrangement shown in Figs. 4, 5, 6 and 7 may be operatively combined with the rail in the same way as described with respect to the form shown in Figs. 1, 2 and 3, or'in any the results sought for may be accomplished.

In F ig. 8 I have illustrated a form of my mprovement which is substantially a combination of the two forms hereinbefore described. The jaw 23 of the clamp 18 which, corresponds to the jaw 23 may be construcn ed in substantially thesame way as is the jaw 23 excepting'that the surfaces 28 and 29' thereof which correspond to the surfaces 28 and 29 need not be inclined unless this is is also formed with a shoulder 30 .which is preferably inclined horizontally in a manner corresponding substantially to the inclination of the shoulder .30.? The wedge 24" has surfaces Ell -and 32 which correspond to the surfaces 31 and 32 and which may be similarly inclined or not according to whether or not the surfaces 28 and 29 of the jaw 23 are inclined or not, and 29 and31 and 32 being always so constructed as-toproperly cooperate. The wedge 24 with a vertical surface 33 connecting the and corresponding to wedge 2%, said surface to properly .cotiperate with the shoulder 30 of the jaw 23', this part of the arrangement being substantially the same as in Figs. 9, 5, 6 and 7. In addition to this, said wedge 24* is constructed with a surface 25 corresponding to the surface 25. and arranged to fit and rest upon the surface 16 of the rail base 16. In the form Shown in Fig. 8 the wedge 24 is similar to the wedge 24;of Fig. l in that it does not contact with the web 15 of the rail as does the wedge 24 in Fig. 4.

the surface 33 of the is further formed effects thereof will be present and will assist v the surface 16 the surfaces 28 and 29.

with the surface 16 In the form now being described the parts occupy positions corresponding to those of the'corresponding elements in Fig. 1, the

wedge 24 being located betweenjthe jaw 23" and the rail base 16 with the surface 25",of the wedge. in frictional engagement with latter tends to creep, the cooper'ation' of the wedge surface 33 and the jaw shoulder 30" will force the wedge 24* or cause. it to climb up on the surface 16" of therailbase l6 toward-the web 15 in the same way as is done in Fig. 1. As the wedge 2-l is moved in' this manner itbecomes firmly jammed between the jaw 23 and the rail base 16 to an increased degree'whereby the grip of, the Wedge surface 25* upon the .surface 16F of the rail base will as a result be increased and a resistance to the creeping tendency set up as will be readily apparent. At the same time the .described actuation of the wedge 21' will exert a lifting'force upon the jaw' also themember 22 23* so that in this form I will act in the nature of. a lever' with the projection 20 as a fulcrum. This will force the jaw 19 into closer gripping engagement the projection 20 into closer gagement with the lower sur ace of said rail base in the same way as in Fig. 1. If of. the jaw 23 and the surfaces 31" and 32 of the wedge 24" are inclined to correspond to the surfaces 28, 29, 31 and 32 of Fig. 4 the action of the wedge upon the-jaw in this respect will be the same as in the form shown in said figure and will provide an additional factor whereby the creeping tendency of the rail is re sisted;- Otherwise the operation of the form shown in Fig. 8 and its effects to resist the creepin tendency of the rail may be substantially the same as in the forms previously described. In the form now being described the parts are also so proportioned and arranged with respect to each other that I arrangement includes the movement of the wedge 24 toward the web 15 is never suflicient to completelydisenga e the wedge from the jaw 23 in this direction. The parts comprisingthe present arrangement mav be combined with the rail in the manner hereinbefore described or in any other'way which may be found suit. able or desirable.

In the form shown in Figs. 9 and 10 the similar to the clamp generall speaking. is

with the rail-base 16 18 and is combined in substantially-the same way as shown in' said clamp l8 is formed at Fig. 4. The one end with a rail engaging. jaw .19 which forms a continuation of a member 22* and forms therewith a recess 21? for the acco'm modation of an edge portion of the rail base 16 in the same way as in Fig. 4, the member of saidrail base. As the wedge 24* is carried along by the rail as the .and the wedge surface 33 of the rail base 16 and; ripping enclamp 18 is forced toward the that the jaw 19"- is forced I surface 16 and of the member 22* a clamp 18 which lower-surface of said rail base." At its other end the member 22 ,is continued to form a jaw 28 corresponding to the aw 23 and arranged in substantially the same manner with respect to the rail basezas illustrated inFig. 4. The jaw 23 is out 1n- 22preferablylying'in'engagement with the wardly from its free end as indicated at 35 and that'portion thereof which lies below the cut is bent outwardly to form a member 30 which extends transversely to the major axis of the clamp and corresponds in location an'd function to the shoulders 30 and 30 herembefore referred to. In the form now being described the wedge 24: is formed with a vertical wedging surface 33" corref forms prev ously deand said rail base with further arranged and constructed so as to extend beneath sa1d member 30 as shown in Figs. 9 and 10.

When operatively combined with the elements comprising the form of my invention shown in Figs. 9 and 10' said elements occupy substantially the same positions as the parts shown in Fig. 4 exceptcorresponding illustrated example the wedge ingthat'iii the 24" does not engage the rail web 15. As the wedge 24 is carried along by the rail in its tendency to creep the cooperation ,of the wedge surface 33* with thejaw member 30' which in addition to its other functions acts as a guide for the wedge, will force the up on the surface 16" of the rail base 16 and toward the web 15. This action of the wedge in thefirst place produces a pressure upon the. member 30" whereby the right in Fig.

wedge 24 9 with the result upon the surface 16 and the rail'base lfi is forced fartherinto the recess 21"thus' upon the upon the lower surface of the rail base 16 so that a resistance to the creeping tendency of the rail immediately takes place. -Atthe same time the surface 25 of the wedge 24 will be caused toincrease its grip upon the surface 16*- of the rail base so that'an addiincreasing the grip of the jaw 19 tional resistance for overcoming the creeping tendency of the" railis exerted through the coiiperation of the surfaces 25 and '16".

Owing to its construction the clamp 18 may be readily stamped from suitable material if this-should be desired thus reducing the cost 'of'p'roduction' and making it possible to produce the.- 'cl'amp in a minimum of time possesses all'of the v s the example shownds substantially the same as the clamps 18 and 18 responds't'o-thejjaws23 and 23 has its lower '-surface; tapcring downwardly or formed and 38will cause thej'aw 23 with inclines 36; and 37 which converge downwardly and meetat a pointpreferably on the verticalcenter line of upper surface of the wedge 24 form is surfaces in the present .constmlcted with inwardly inclined 38 and '39 converging for instance toward the longitudinal center line of said wedge the inclination of the surfaces 38 and 39 corresponding substantially to that of the jaw surfaces 36 and 37 as shown in Fig. 12.;

In practice the clamp 18 occupies a-position on the rail corresponding to that occupied by the clamp 18, the wedge 24 being located. between the jaw 23 and the rail base and in frictional engagement with the surface 16" thereof and with the jaw surfaces 36 and 37 in operative engagement with the wedge surfaces 38 and 39 as. shown in Fig. 12. As the wedge 24 is carried along by the rail as the latter tends'ito' creep for instance in the direction of the arrow in Fig. 12 the coiiperatio'n of thesurfaces 36 to. climb yup 38 whereby as it were on the wedge surface the member' any creeping tendency which may occur.

It will be secninallof the forms .of-mv improvement herein illustrated and-Tide scribed: that the creeping tendency offthe' which are exerted on the rail" at bothiflfside's resist and overcome any-creeping movement of the rail.

My improvementin all of its forms is extremely simple in construction'and easy to assemble and combine with the rail thus reducing theicost of production to a minimum and avoiding the necessity, for skilled constructed and arranged in such a manner that the'horizontal surfaces of the clamp jaw and of the wedge wliich engage each other are fiat. With such arrangement the danger of dislocation of the wedge in a reis reduced to a minimum.

In all of the forms the wedge may be d i enfto an initial operative position by means of a hammer or other suitable imple ment it being understood that the may occupy positions on the rail-and. relativcly to the tie reversed from the positions shown this "depending upon the direction in which the rail has a tendency to creep. v
