Specification or Letters Patent.

Patented Nov. 23, 1909.

Application filed April 28,: 1908. Serial No. 429,653.

To all whom it may concern:

rnn, a citizen of the United States, and a resident of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Traps, of

which the followingis a specification.

My invention relates to improvements in traps of the character illustrated in the drawing of my application, Ser. No. 370,511,

filed April 26, 1907, and the object of this invention is to produce a trap that can be made entirely of sheet metal and wire and at the same time possess great strength and rigidity for the weight of the metal used.

comprises a numb-er of sheet metal bars or stays which are connected to flanged rings at the entrance and at the discharge end of the trap, the said bars or stays supporting and holding in position the wire forming the main part of the trap. Another novel feature is the construction of the rings at the ends of the trap and also the door or closure, as well as other details which will be hereinafter referred to.

My invention therefore consists of the trap as shown in its preferable embodiment in the accompanying drawings and as will:

be more clearly described and claimed at the end hereof.

Figure 1 is a top plan of a trap constructed in accordance with my invention. Fig. 2 is a vertical central section. Fig. 8 is an end view' from the front of the trap. Fig. 4c is an end View from the back of the trap. Figs. .5, 6 and 7 are details tobe more fully described hereinafter.

Referring now to the construction by nu merals: 1 designates a series of bars or stays which are made as illustrated and described in my aforesaid application No. 370,511. As there disclosed this stay or bar comprises a substantially U-shaped piece of metal hav-;

- bar.

As illustrated in Fig. 3 my trap comprises two of these bars or stays 1 at opposite sides or ribi i of the bottom of the trap, a similar bar or Be 1t known that I, \VIL'LIAM W. VVononsstay 7 at the top of the trap and two bars or stays 10 and 12 between the top and bottom bar on each side of the trap, thus making seven bars or stays in all. It will be noticed that these bars or stays are straight for the major portion of their length and then each end of each bar or stay is curved so that the ends of the bars will all point toward a common center as clearly illustrated in the drawings. Instead of bringing the bars or stays to one common point, they stopa short distance from'what would be their meeting point and their ends are I connected to rings 15 and 17 at opposite My trap, in Its preferable embodiment,

.ends of the t'rap, one of the rings 15 fornr ing the entrance and the other ring 17 forming the exit at the opposite end of the trap. The ring 15 at the entrance of the trap is as clearly shown in the drawings, formed of sheet metal and has a rounded inwardly projecting member 18 which provides an entrance which is smooth and without any rough edges. The metal forming the ring is then formedwith an annular groove 20 the ring proper it is formed with a flange designated by the numeral 22. The groove is for the purpose of receiving a wire 24 under which is passed the end 26 of each stay orbar and aflords the means of connecting the seven stays or bars to'the ring. The ring 17 at the closure end of the trap is formed iiisubstantially the same way except thatIins'tead of having'the metal formed .80 and then after being bent backward from into the rounded inwardly, projecting portion 18', it is substantially flat so as to provide means'for permitting the door to close against and lwitliin the ring. But the seven bars or-stays are connected'to the rear ring or closurefexactly the same as at the front end or the entranceof the trap.

Therear-fend is provided with a door 27 preferably formedof sheet metal and hinged at the top of the ring'asf clearly seen in Fig. 2 T Thus the door may be lifted upwardly as clearly indicated in the drawing and in order to make this possible from the outside of the trap, I provide a handle QS which is pivoted to the lower end of the door and the other end of this handle is formed into a spring catch 29 which coacts with the central stay or bar and locks the doorclosed as clearly indicated in Fig. 1. The wire which forms the main portion of the trap-is formed of one single piece, is wrapped around all the stays or bars and is secured thereto by the flat strips or ribbons as hereinbefore described and the last coil of this wire is secured in position by having the ends of the flat strips or ribbons passed around it and then doubled upon itself as clearly seen in Fig. 5. To make the bottom of the trap more rigid and secure, I

pass a couple of

heavy wires

30 and 31 along the inside of the trap and connect them to each coil of the continuous wire by wrapping wires 33 as clearly seen in Fig. 2.

In order to make the trap so that it can not be easily rolled by the rats, I provide two extensions 34 which are preferably connected at the bottoms and comprise two frames substantially U-shaped, the stems of the U having two loops 36 which fit around two coils of the wire and permit the extensions to bepulled out or moved in, in a manner easily understood.

The partition between the two parts of the trap comprises two stays or bars 40 connected to the two bottom stays or bars of the trap at its ends and bent in the shape shown in the drawings, and to the U-shape part of this frame I connect three stays or bars 41, 42 and 43 which are connected to the trap proper as indicated in the drawings and around these stays or loops is wrapped a wire frame 46 which is secured in position in exactly the same way that the Wires are secured to the main stays or bars. There is however an opening left in this frame 46, at the U-shaped part of the stays or bars 40, through which the rat may enter and this opening is closed by a trap door 48 pivotally held in position and provided with a Wire weight 50 to hold it in the closed position and yet permit of the trap door being opened by the passing of a rat and automatically closed as the rat passes into the trap proper. It will be noticed that the wires which close the ends of this partition instead of being bent around the frame of the partition, under the trap door 48, are bent downwardly and left exposed as shown at 52 so that any attempt on the part of the rat to open this trap door after he is caught will be prevented by the objectionable points of these wires making it unpleasant to make any such attempt successful. I consider this an important feature.

From the foregoing and the accompanying drawing it will be seen that I have pro-- duced a trap which, though made of sheet metal, is exceedingly strong and yet it possesses all the features necessary in an ideal trap and at the same time can be made sufficiently cheap so as to come within the price at which it is necessary to make a successful trap.

It is obvious that changes and modifications may be made and I do not limit my invention to the exact form illustrated, but refer to my claims in order to determine the scope of my invention.
