ANTISPREADING ATTACHMENT FOR RAILS.

Specification of Letters Patent.

Patented May a, 1915.

Application filed November 6, 1914. Serial No. 870,681.

To all whom it may concern:

Be it known that I, MARY E. SIMPSON, a citizen of the United States, residing at Yates, in the county of Kimble and State of Texas, have invented certain new and useful Improvements in Antispreading Attachments for Rails, of which the following is a specification.

My invention relates to anti-spreading devices for railroad rails.

The invention aims to provide a structure of this nature especially comprising a span tie located between the rails and adapted to connect with dogs, one dog being connected with each of the rails.

A second object is to provide a novel means whereby the dogs may be fastened to the rails.

A third object of the invention is to provide a novel means whereby the span ties may be connected to the dogs, and specifi cally to provide the span tie having dove' tails at opposite ends thereof having their side walls inclined and the dove tails adapted to be engaged in suitably shaped recesses in the dogs, and adapted to receive above the dogs, suitable fastening means.

Another object of the invention is to provide the means mentioned above of such nature that the same .may be applied to existing types of rails and while the rails are in place fastened to the usual ties.

A fifth object of the invention'is to provide a meansto secure the span tie against movement longitudinally of the rails when in place, specifically very effective means for this purpose. 4. v

With a view to attai ing the foregoing objects as well as additi nal objects, as will become apparent from the description hereinafter following taken in connection with accompanying drawings illustrating the preferred embodiment, the invention resides in certain novel features of construction, combination and arrangement of parts.

In said drawings: Figure 1 isv a top or plan view showing a portion of a track hav-' ing my improved means applied thereto; Fig. 2 is a transverse sectionalview' on the line 22 of Fig. 1; Fig. 3 is anenlarged transverse sectional view on the line 33 of Fig. 1; Fig. 4 is a perspective view of one of the dogs employed; Fig. 5 is a perspective viewof one of the span ties; Fig. 6 is a perspective view of one of the lock member retainers used to connect certain. of the parts; Fig. 7 is a perspective view of the lock memberemployed in connection with the retainer of Fig. 6; Fig. 8 is an enlarged cross sectional view on the line 88 of Fig. 1, and Fig. 9 is a. detail fragmentary perspective view of one end of one tie connector bar.

Referring specifically to the drawings, wherein like reference characters designate like or similar parts, the usual railway rails, and ties to which they are fastened, are shown at 1 and2 respectively. The rails 1 are shown in Fig. 1 as curved but it is to be understood that the invention may be practised in connection with straight rails equally as well.

Taking up the description of my improvement, numerals3 designate dogs each com prising a flat plate 4 to engage the under surface of the rails and from which plates 4 extend riser flanges 5 from whichextend inwardly, flanges 6 to engage the upper surface of the base flange of the rails adjacent their outer edges. In effect by the'provision of the flanges 5 and 6, a groove is formed which receives the outer portion of the base flange. This base flange in the drawings is designated 17. Fastening elements 8 and 9 are provided by means of which the dogs 3 are completely secured to the rails.

The fastening element 8 consists of a re-' tainer having a tang plate 10 below which and through the plate 3, bolts or equivalents 11 pass for the purpose of fastening the retainer to the dog. These retainers have riser walls or lugs 12- extending at right angles to the plate and being provided with apertures 13 adapted to aline in a plane transversely of the rails. The fastening element 9 is in the nature of a bar having an angle lug 14 at the driving end thereof. In use, to complete the fastening of the dogs to the rails, after the retainers have been secured to the dogs and the flange 6 brought.

into engagement with the tread flanges 7 bar 9 is passed through the apertures 13 until it engages the upper surface of the tread flange of the rail whereupon it is driven toward the rail by a hammer or the equivalent. As the upper surfaces of these tread flanges are inclined upwardly, bar 9 is bent by such driving action so that the corners of the flanges at the top of the apertures13 will bite into the bar and the parts therefore be in tight relation. Beyond the inner edge of the rails, vertically exa all.

tending dove tail recesses 15 are provided,

the side walls of which are converged up wardlyat 16. Ties 17 extend thespace between opposite dogs and are fastened there to. These ties at each end have projections 18 which are dove tail in shape and the sides of which converge upwardly at 19. It is to be noted that the dogs and ties '17 are rails and then moved upwardly with the dove tails 18 passing into the dove tail recesses 15. Due to the convergence of the walls 16 and 19, the ties 17 are limited in their upward movement to position Where the top face of plates 3 and top faces of tie 17 will be in the same plane. After the tie is thus connected, suitable fastening means is used to secure the same against downward displacement. To this end retainers 20 exactly similar in sha e to the retainers 8 are secured to the has 17 by means of bolts 21 passing through the ties and through a base plate 22 of the retainer or fastening member. Through alining apertures 23 in riser lugs 24 extending from the plate 22, is passed a fastening member in the form of a bar 25 having a head 26 to prevent displacement in one direction. It

will be noted from Fig. 3 that the bar 25.

projects beyond the outer faces of the lugs 24 so as to rest on the upper surface of the plates 3.

In addition to being capable of ready attachment to rails when laid, the anti-spreading \device of my invention may be readily detached and removed from the rails when desired upon the removal of fastening members 9 and 23, the detachment of ties 17 from the dogs 3 and the removal of the dogs.

I prefer to employ means to prevent movement of the ties 17 longitudinally of the rails. To this end connectin bars 28 are provided which fit into mortises 29 of the ties 2 and are fastened therein as by spike 30 passing through the bars 28 and ties 2. At each end, the bars 28 'areprovided with projections in the form of dove tails 31 having upwardly converging side walls 32. The ties 17 midway of their ends and on each side edge have recesses 33 of dove tail form, the side walls of which converge upwardly at 34. The dove tails 31 extend into the recesses 33 and thereby connect the ties 17. -Only a single fastening member 30 is used to connect the bars and which fastening member is not even essential since the bars rest on the ties 2 and the dove tails 31 extend into the recesses 33. Due to the particular shape of the dove tails and recesses, the bars cannot move upwardly and owing to the fact that they rest on the ties 2, they cannot move downwardly.

It is to be understood that inasmuch as I have shown only the preferred embodiment of my invention, that changes in the details of construction, arrangement and combination of the parts may be resorted to without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim is 1., In combination with track rails, dogs, means to removably fasten said dogs to the rails, said dogs being provided with vertically-extending recesses, said recesses extending throughout the depth of said dogs, and means engageable with said recesses for connecting said dogs.
