IMPROVEMENT IN IRON FENCES.

MMM-

The Schedule ref-erred to in these Letters Patent and makingv part of the same -*#.v-v--n I, SoMMEns GnownLL, of the city of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Cast-iron Railings, ci" which the following is a specilcation.

llhe nature of my invention consists in a novel inode ot connecting the pales of a cast-iron fence' with the longitudinal rails or rods of the saine, whereby bolts or rivets are dispensed with, the pales and rails being held together by means of cross-grooves in the rear side ot' the former, which receive the latter, and clasps connected with the saine, which hold the railsin place, as hereinafter described.

To enable others to apply my invention to practice, l will now give a full description thereof.

In the accompanying drawings which malte a part of this specification- Figure l is a front elevation of one ofthe pales A, clasps B B at its upper end, and a portion ot' rail 1) in connection.

Figure 2 is a perspective view ot' a piece ot' one of the rails D and clasp B.

Figure 3 is a side view of one of the clasps B.

Like letters in all the figures indicate the same parts.

A represents one of' the pales of the fence, which has semicircular grooves c in the rear side of the projections l), for the reception ot' the rails or rods 1).

'Une or more clasps B, are passed through slots c, seen in the lower projection l). These clasps are provided with flanges d, which are brought against the front side of the projections l), and when in position, the eyes c, are in range with the semicircular grooves ,so that, when the rails or rods D are pushed through the eyes e into position, as represented in fig. 2, they are held securely in the grooves a, the outer portions ofthe eyes opposite the grooves binding on the rear side of the rails or rods sufciently tight-to hold them securely in the grooves. One of the clasps B is represented in detail in iig. 3.

It will readily be seen that the pales and clasps may he cast snicientlyaccurate to admit of the felice b eing put together as they come from the founder without any finishing; and that, there being no screws or rivets necessary in confining all the parts of a panel together, the felice may be cheaply made, and at .the same time have a neat tinish. rI he rails or rods, being covered in front bythe projections I1, are not seen in front of the fence. It' desired, the clasps B maybe so constructed as to have an even finish with thel'aee of the pales, by dispensing with the flanges d and eountersinkiug the heads. The heads of the clasps B may have a carved or other iinish, with the projections b, to lool; like a part of the same.

The drawings representround rails; yet the improvement, it will be seen, is adapted to anyform of rails by having the grooves a ofthe pales, and the eyes e of the clasps, of corresponding form.

What I claim as niy invention, and desire to secure by Letters Patent, is-

The clasps B,i`ormed as described, with ring portion e, in combination with the pales A, having the slots e .and horizontal groove or depression a. adapted to the form of the Vrail or rod 1) which passes through the ring c, all constructed substantially as described.
