7 Claims.

This invention relates to blames and more particularly to hames of the type constructed partly of wood or other non-metallic material, and partly of metal.

The objects of this invention are to produce a hame of this type of greater strength and lighter Weight than similar hames heretofore constructed; also to provide a hame of this kind which can be more readily constructed and which l is more durable than similar hames heretofore made; also to provide a hame having a nonmetallic body portion which is mortisedtc receive a portion of the metal reinforcing strip to provide a better cooperation between the parts; also to provide a hame in Which the body portion is reinforced by means of a metal strip of channel-shaped cross section; also to provide a llame of this kind in which the channel shaped reinforcing strip and the body portion of the 2O haine are provided with cooperating portions for holding these parts in their correct operative positions relatively to each other; also to improve the construction of hames in other respects hereinafter specied. In the accompanying drawing:

Fig. 1 is a front View of `a hame embodying this invention.

Fig. 2 is a side view thereof. Fig. 3 is a fragmentary enlarged front View 3@ of the lower end of the haine.

Fig. 4 is a similar fragmentary view of the upper end of the hame.

Figs. 5 and 6 are sections thereof taken on lines 5-5 and 6--E, Fig. 4. ,5 Fig. 7 is a section thereof, on line 1-1, Fig. 1. A represents the body portion of the hame which is usually made of Wood, but which may be made of any other material. In hames of this kind a flat metal strip or backiron is usually employed for reinforcing the outer edge of the haine, and is secured thereto at intervals by rivets or bolts. In accordance with this invention, I provide the hame With a reinforcing strip of such cross sectional shape that a portion of the i5 strip may enter into a mortise in the body. The mortise in the body portion and the part of the reinforcing strip extending into the same preferably extend throughout the greater portion of the length of the haine, so that a uniform re- 50 inforcement of the hame substantially throughout its length Will result, instead of having the strip reinforce the hame body against certain stresses only at the rivets or bolts connecting the body and strip. The reinforcing strip may be of any desired cross sectional shape capable of cooperating` with aflongitudinal gIOOVe 0r mortise in the body. AIn the construction illustrated, a reinforcing/strip B of channel-shaped cross section is employed and is arranged With the flanges bof the channel extending tovvard and engaging with the body portion A- of the hame.

In orderto provide for the desired cooperation between the body of the hame and the reinforcing strip, the hame body is provided at the two opposite edge portions thereof with mortises 9 ,putin the wooden or non-metallic `body portion andwiv'which the flanges b of the channel may enter. Preferably a snug t is provided between the legs of the channel member B and the mortised portion of the body A, so that lateral movement of the reinforcing strip B with reference tothe body of the hame is prevented, and so that any iiexing or bending of the hame body, due to the strains to which it may be subjected, Will be transmitted to the reinforcingstrip B. By means of this arrangement, an excessive increase in the Width of the hame because of the depth of the channel-shaped reinforcing strip B is also prevented.

Since a reinforcing strip of channel or other structural shape has materially greater strength than a ilat or curved strip of the same cross sectional area, it is possible to make my improved reinforcing strip of relatively thin metal and yet produce a hame of greater strength than those heretofore made in which reinforcing strips of rectangular cross section Were used. It is also possible to dispense with some of the rivets Which were heretofore necessary to hold a flat reinforcing strip in placeon the hame body, and consequently, I employ ordinary nails I0 at intervals for holding the reinforcing strip on the body portion of the hame. Such nails do not weaken the body portion to the same extent as rivets, for the reason that the nails do not extend entirely through the body portion and may be of smaller diameter than rivets heretofore used. This results in a further increase in the strength of the haine.

In certain types of hames, it is desirable to have the reinforcing strip overlap the ends of the hame. I can accomplish this result by means of my improved reinforcing strip by either removing from the ends of the strip any legs or flanges, so that the ends of the strip will be substantially flat, or by flattening these ends by folding such legs or flanges against the Web of the reinforcing strip. For example, when a channel-shaped reinforcing strip is employed, I

can bend or fold the flanges b toward each other and against the Web of the channel. These folded legs or flanges Il consequently substantially double the thickness of the flat portion of the reinforcing strip and produce additional strength at the ends of the hame. These ilattened portions of the reinforcing strip can be bent over the opposite ends of the hame, as indicated at I4 and l5, and may be secured in their correct'positions by means of rivets lli and Il passing through the bent-over portions Ill and l5, the body of the hame, and the channelshaped portion of the reinforcing strip B, as clearly shown in Figs. l, 3, 4 and 5. To the lower bent-over portion l5 of the hame, the usual hame loop I8 may be applied. These bent over portions enable the reinforcing member to be securely held against movement lengthwise of the hame body. When this construction is used, it is also possible to eliminate the nails l0 entirely, since the reinforcingr strip will be securely held against endwiseas well as lateral movement relatively to the body. When the legs or flanges are bent inwardly at the ends of the reinforcing strip B,

they also act as Wear strips or members for the hame loop I8.

20 represents the usuall harne` ring which may be passed through the eye of an eye bolt 2i extending through the hame and riveted over at its end on the opposite edge of the hame. Z2 represents the usual trace connection which may Y also be of any suitable orusual construction,and

nected at different elevations. The trace connector may ,also provide for the securing of a breast'strap Vring 24 to the hame.

An end of the body portion of the hame, for example, the upper end, as shown at le, is preferably formed flat and extends at nearly a right angle to the opposite sides of the hame, and the adjacent end portion of the reinforcing strip is bent over this flat end of the body portion, so that a very much stronger structure results than when the upper end of the body portion is rounded. When the hame is formed inr this manner and subjected* to severe strains, the flattened end of the body portion bears against a flat face of the reinforcing strip which prevents relative displacement of the strip and body portion, and also provides two flat surfaces of fairly extensive area which bear one against the other and thus resist to a greater extent 'any relative displacement of the reinforcing strip and body.

Haines of the kind herein described are lighter and have greater strength than haines vof this type heretofore made, and this is, of course, of material advantage, since it relieves the draft animal of a corresponding amount of weight without sacrificing the strength of hame.

I claim as my invention: 1. A hame having a non-metallic body provided V-With a mortise extending lengthwise thereof, a Vreinforcing strip secured to a side of the hame body and having a flange extending intoI said mortise, and a web extending parallel to said side, said flange being folded flatly against said web at an end of said hame and the end portion of said strip with said folded flange being bent across the end of said body portion.

2. A hame having a non-metallic body provided with a mortise extending lengthwise thereof, a reinforcing strip secured to a side of the hame body and having a flange extending into said mortise, and a web extending substantially parallel to. said side, said flange being folded flatly against said web at the ends of said strip, said ends of the strip being bent .across the ends of `I said hame body to hold-said strip against movement lengthwise of said hame body.

3. A hame having a non-metallic body portion, and a reinforcing strip of metal secured to the outer edge thereof and of channel-shaped cross section, and having the flanges of the channel atan end thereof folded inwardly, said endV being bent over and secured to the end of the body portion.
