WOOD BINDER.

a log or timber, will result in cracking 01" checking. This is particularly true of railroad ties, which, in a very short time after being cut and pre ared for use, will check or split at the end, such a split eventually extending into the tie to such an extent as to make it unsafe and often useless long before the tie' is rotted or decayed in the usual manner. Various devices have been tried with the idea of drawing the ends of ties, as well as other timbers, together either before or after a crack has occurred. Nearly al1 of these have a tendency to augment the crack or split, either in the manner of application or in their construction. Such a device, to be successful must be simple in construction as well as in application, must be comparativel inexpensive to make and should be app icable without danger of splitting the wood.

In the accompanying drawings, I have shown several embodiments of the invention. In this showing:

Figure 1 is a perspective view of a railroad tie showing theeinvention applied2 Figure 2 is a central vertical longitudinal 40 sectional view,

Figure 3 is a front elevation of the binder removed,

Figure 4 is a detail sectional view on line 4-4 of Figure 3,

Figure 5 is a. front elevation of another form of the invention, and,

Figure 6 is a detail sectional view on line 6-6 of Figure 5. Referring to the drawings, the reference numeral 1 designates a railroad tie or similar timber. The binder forming the subject matter of the present invention consists of a bar 2 of steel or iron, which is substantially wedge shaped in transverse cross-section, as shown in Figure 2 of the serted. Each of the split members will have a cross-section of a half wedge, as shown in Figure 4 of the drawings.

In the form of the invention shown in Figures 5 and 6of the drawings, a bar 4 is employed of suitable shapeto provide end members 5 of wedge shaped cross-section, as shown in Figure 6.

The binder is log, with the wedge point next to the surface, 'and driven in until the point of the wedge has penetrated the wood and the top or back of the binder is llush with the surface thereof. This may be accomplished with a sledge or hammer, requiring no skill and no apparatus, and when the binder is so applied it will rmly hold the bre of the 10g or tie together so that fit will not split in the usual manner, and the life of the timber, log or tie will be greatly extended. The exposure to moisture in the wood or from the outside has a tendency to oxidize the steel or iron, thus holding it more firmly in place.

I do not limit my invention to any particular size'or relative dimensions, so long as the general shape is preserved of a bar having a wedge' shaped cross section with two rearwardly curved members on each end, nor do I` limit its use to the preservation of wood from cracking, but it may be used to hold together two on more logs or timbers in structural work.

What I claim as my invention is:

. 1. A wood binder comprising a bar having a substantially wedge shaped cross, section, having two rearwardly curved and structurally integral members Aon each end, each of said members having a substantially wedge shaped cross section.

2. A wood binder comprising a long and relatively narrow body having a substantially wedge shaped cross section; two structurally integral members on each end of said laid on the end of a tie orI i@ Lamme body, each of said members also having a tion, the end of said bar being provided vwedge shaped cross section of substantially with two rearwardly curved and structuthe same nature as the cross section of said rally integral members, each of said mem- 10 body, and each of said members being curved bers having a substantially wedge-shaped 5 outwardly and rearwardly from said bar. cross section.

3. A wood binder comprising a bar having a substantially wedge shaped cross sec- AMSEY P. LLOYD.
