Be it known that i, Hanauer O. Carreau', citizen of the United States, residing at Sanford, in the county of Orange and State of tv Florida, have invented certain new and useful Improvements in Toot-hed Spikes, of which the following is a specication.

This invention comprehends certain new and useful improvements in spikes designed particularly for use in securing railway rails .fte ties, and the invention has for its ri mary object, a sim le, durable and eiiicient vnyconstruction of rai way spike, the parts of which are so arranged that the s ike maybe e'ectually l prevented hom becoming loosened acciden- A tally, while at the same time permitting it to be retracted whenever desired With this and other objects iii view as will fully appear as the description proceeds, the invention consists essentially in a spike embodying a body portion with a ri penetrating toe or point and head, and a ocking member pivotally connected to the spike and so arranged 'l' ber will be engaged with the base ange of j ythe rail and thereby impart a tilting move- 3 mentY to the locking member so as to force I the toothed portion thereof outwardly into rm engagement with the tie, the teeth of such portion of the locking member being tuallv upwardly beveled as shown so as to eii'ec prevent the retraction of the spike p without first tilting the locking` member to a sition where its toothed edge or edges lie flush with the side edges of the body portion of the spike. And the inven- 74 tion also consists in certain constructions, arrangements and combinations ofthe parts Y that shall hereinafter fully describe and claim. For a full understanding of the invention, refereixce is to behad to the following description and accompanying drawings in which: Figure 1 is a side elevation of a spike constructed in accordance with my invention, 5 the same being shown partly driven into the tie; Fig. 2 is a similar view with the spike locked in the tie; F ig. 3 is a perspective view i ofthe spike; Fig. 4 is a side elevation, partly broken away or' a. modied form of spike; 55. and, F ig. 5 is a transverse sectional view of y suchmodisedfem.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The body portion l of the spike is formed with the usual head 2 and with a penetrating toe or point 3. The main body portion 1 of the spike is recessed in its side edges as indicated at 1i, roin a oint near the toe 3 65 to a oint near the hea 2, for the rece tion of si e bars 5 of al O' member, sai side bars embracing the bo y portion of the spike and being pivotally connected thereto intermediate ot their ends by a rivet 6 or 70 similar fastening device. The side bars 5 of the lo 0' member are of a width equal to or less than the width of the body ortion 1 so that the sideedges of said si e bars will not project beyond the margin of the body portion when the locking member is arranged with its side bars in longitudinal alinement with the body portion of the spike. The side bars 5 of the locking niember are filned gypte tte ppt il amid2 on 80 correspon ge switivy rge upwardly facing and preferably beveled teeth 7 and may also be provided below the i pvot 6 and on correspondingly opposite e teetiis 8, both sets of teeth being designed to embed themselves into the wood of the tie when the locking member is tilted relative to the bod tportion 1.l 1n the inoperative position o e ends of the side bars 5 preferably lie close to the lower end walls o the recess 4, ush with the shoulders formed by the upper end of the toe 3. t

The locking member includes addition to the side bars 5, a part or portion which is preferably formed integral therewith and which in the invention now being described is in the form of abail or loop 9 which is designed to artially encircle the head 2 of 100 the spike w `ch is normally oiiset therefrom as clearly illustrated in the drawing. When the side bars 5 lie flush with the side edges or margins of the body portion 1, the bail or loop 9, which is angularly disposed to the side bars 5 preferably lies in a plane ust slightly below the plane of the hea 2 whereupon when the spike is driven nearly home, the bail will engage the adgacent base flange of the rail and will consequently rock the lockina member in a osition to project the toothed edges thereo the teeth ,A

with relatively small corresponding 85 locking member, the lower 90. Y

. of the spike. y ,A f Y In that form of the invention illustrated 5 in Fig. d 1* designates the body portion of the spike, the saine being formed with a longitndinal slot l?. extending therethrough trom ont to rear, and the locking member Y embodies a single bar 5* pivotally mounted 10 intermediate its ends as indicated at 6* in said slot. The opposite edges of the bar 5* are toothed or notched as indicated at 7 vand 8* respectively and the upper end `of the bar 5 is formed with a proiecting portion in the form of a tongue 9* designed to exltend underneath the head 2*, and thereby ada ted to rock the locking member.

rom the foregoing description of the y construction and o ration'o that form of i Y20 the invention which was rst above de scribed, together with the accom anying i4 drawing, the operation or practi use of the isst described form will be apparent. f While I have shown or described two y 25 forms or embodiments of the device, it is obvious that my invention is not limited thereto, but that various changes or modifil cations may be made in the construction, arj' Arangement and proportion of the parts with- 30 ont departing from the spirit of the invention as dened in the appended claims. y l v As the locking member in each instance, is, l in the preferred construction of parts, pivotally connected intermediate of its ends to the body portion of the spike it will act in the manner of a lever, so that when its up- 'p'er end is tilted in one direction, its lower Cend will'be tilted in thewposite direction Q and the toothed edges be rmlg em- -40 bedded in the tie on the op osito si es of l the main or bodydportion of e spike, there- T, by serving to ho the spike securely in lace 1 -imuch more eectually than if the loc g member were to lie in its operative osition 4,5 entirely to one side of the spike. t is oi course, immaterial just where the pivot int be relative to the locking memr. It might be located at the approximate point illustrated in the accompanying draw- '50 ing, or at any other desired point. Manifestly the rivet may be of any desired size, so as to eii'ectuall brace the locking member :Liand strengthen e arts and prevent them from becoming acci entally separated.

lm that form of the invention illustrated is .fin Figs. 1, 2, and 3, it is to be particularly w noted that the recesses in the side saggi--the body portion form upwardly racing l shoulders at the tapered int or toe to pro '60 duce a barbed point.

l feetfi'aliy prevent the accidental withdrawal .ence not only does d.. firmly embedded the tie and Kef-i es of the rivet ivlii;Z pivotally connects the lockscarso ing member with the body portion of the spine tend to prevent the spike from being withdrawn by breaking the connection between the two parts, but the barbed point also assists in securely holding the spike in the tie, even should the connection between the locking member and body portion of the spike be broken.

Having thus described the invention, what is claimed as new is:

l. A spike, comprising a body portion, a locking member pivotally connected thereto and formed with a tooth, and means carried by said locking member adapted to engage a base iiaiige o? member may be rocked to an inclined position relative to the body portion.

2. A spike comprising a body portion and a locking member ivotaliy connected thereto intermediate o its ends, said locking member being toothed on its edges and embodying means at its upper end designed to engage the base flange .o a rail for the pur` pose specified.

3. A spike, comprising a body portion, a locking member pivotally connected thereto and provided at its u per end below the head of' the spike wit means adapted to engage the base tlang'e of a rail for the pur ose ecied, the ocking member being orme with oppositel facing toothed edges adapted to be projecto beyond the body portion of the spike by and upon the engage-V mentif sich means with thediiange. d-

4. ecom rising" aboy oronan a locking; meinberpnivotally connidctedv theretmiaed to 'e iiush with the margin thereof mffomed with a toothed edge and also at one end with a portion adapted to eiiect the rocking of the locking member, said part exten 0 underneath the head of the spike, as and or the purpose set forth.

5. A spike, comprising a body portion, a locking member pivotally connected thereto and provided at its upper end belowthe head of the spike with a forwardly 1dpro ecting portion adapted to engage e use ange of a rail, the lockinfr member d' formed with a tooth adapted to projecto beyond the body portion of the spike by and upon the engagement with said flange, the locking member being formed at its u p r end opposite the projecting portion w1 a luv', for the purpose set forth.

n testimony whereof I aiiix my in presence o two witnesses.
