UNITED STATES CHARLES C. WARNE, OF YONKERS, NEW YORK.

MULTIPLE TIIE PLUG.

Application filed March 10, 1926. Serial No. 93,554.

This invention relates to wooden plugs which are adapted in railway track practice to be driven into holes left in wooden ties after the withdrawal of spikes therefrom, and more particularly to a unitary construction and arrangement of a group or plurality of said plugs for the easier and safer handling or shipping of the same.

This invention constitutes an improvement over my Patent No. 1,518,470, issued to me on the 9th day of December, 1924, and provides for further simplification of the manufacture of a unitary construction of railway tie plugs, and particularly to increase the strength of said construction and the safety wherewith it can be handled or transported, while at the same time rendering the plugs severable or detachable into individual units or plugs with the maximum ease and facility.

lVith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a perspective view showing a blank with its upper and lower surfaces modified according to the cross section of the desired plugs.

Fig. 2 shows the blank formed by kerfs into a unitary assemblage of railway tie plugs.

Fig. 3 shows a pair of plugs detached from a group unit preparatory to using.

Fig. 4: is a perspective view of one plug of a pair detached from the other and ready for use.

Fig. 5 is a view of a modification of the invention and shows a pair of plugs detached from a group unit.

The blank 10 is rectangular and of any suitable or convenient width depending on the available lumber or stock and preferably twice the length of the finished plug. The shaping or molding of the blank is per formed cross-wise of the grain of the wood so that the finished plugs will extend lengthwise of the grain and be sufliciently stiff to be driven into the holes left in the railway tie after the usual spikes are withdrawn.

The surfaces 11 and 12 are. moulded or formed by any suitable means such as a planing machine to have the central V- shaped grooves 13 and 1 1 transverse of the grain midway between the ends of the blank, the vertices of the grooves being adjacent to each other, to form the points or ends of the plugs. The surface 11 is likewise offset inwardly to form the rldges 15 extending in substantial parallelism to the grooves at the ranged as to provide connecting webs 19 or' the like between adjacent pairs of plugs. The kerfs are formed by means of a gang or other suitable tool, the blank or gang saw moving at fixed perpendicular distances from each other thus providing a series of webs 19 of substantially equal size at each of the ridges 15. The depth of the cuts is such as to wholly separate the shanks of adjacent pairs of plugs from each other. Likewise the adjacent heads 16 are separated from each other except at the portions of the heads which are offset laterally from the shanks.

When a plug is to be used, a pair is first detached from the group as by splitting at the webs 19, and then the pair is forcibly broken or separated into individual plugs at the points of the plugs.

The manufacture of this invention is particularly simple since a blank can be quickly run through a gang saw with a single-movement. Transporation and handling of the device is rendered safe to a maximum degree, because inasmuch as the pairs of plugs are secured together at their remote ends possibility of accidental separation of the pairs of plugs or other breakage of the group is eliminated. Moreover a pairof plugs can for use he more easily separated from the group than had heretofore been possible, since a web 19 can be broken individually, and then its opposite or co-operating web to finally separate a pair of plugs.

In Fig. 5 I show a modification of my invention 'wherein webs 19 are provided formed by a saw 20 shown in dotted lines,

the relative movement between the blank and the saw being axial withrespect to the center of the saw. The base of the kerfs at the heads of the plugs lies therefore along the circumference of a circle. In other respects, this construction is the same as described hereinbefore.

I claim:

1. A unitary assemblage of railway tie plugs comprising a plurality of plugs formed in pairs of integral construction at the points of the plugs, said pairs of plugs being of integral construction side by side atthe heads of the plugs and being separated from each other between said heads to facilitate splitting of one pair from an adjacent pair at said heads.

2. A unitary assemblage ofrailway tie plugs comprising a plurality of plugs formed in pairs of integral construction and lyingend to end, said pairs of plugs being of integral construction side by side at the outer ends of said plugs and being separated from each other between the outer ends to facilitate the splitting of one pair from integral construction at the said portions, the pairs of plugs being separated from each other by a straight out between the shanks .of the plugs of adjacent pairs, the cut passing likewise between the heads of the plugs except between the portions aforesaid.

44-. A unitary assemblage of railway tie plugs comprising a plurality of plugs formed in pairs of integral construction and lying end to end, the heads of the plugs in cluding portions offset laterally from the shanks of the plugs, said pairs of plugs lying side by side and being of integral con struction at said portions, the pairs of plugs being separated from each other by a straight out between the shanks of the plugs of adjacentpairs, the cut passing likewise between the heads of the plugs except between the portions aforesaid.

'5. The method of making a unitary assemblage of railway tie plugs comprising forming a ridge upon a face of a blank, and then applying a tool at the opposite face of the blank to form a series of kerfs at an angle to the direction of said ridge and extending through the blank except through said ridge.

6. A unitary assemblage of railway tie plugs comprising a plurality of plugs formed in pairs of integral construction at the points of the plugs, said pairs being separated from each other, and webs remote from the points and integral with the plugs to connecttogether adjacent pairs of plugs. In testimony whereof I affix my-signature.

CHARLES C. VVARNE.
