DEVICE FOR APPLYING INSECTICIDES.

SPECIFICATION forming part of Letters Patent No. 507,615, datedOctober 31, 1893.

Application filed Aprill5, 1893. Serial No- 470,523- (No model.)

To all whom it may concern:

Be it known that I, MARY A. HAWLEY, a citizen of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Devices for Applying Insecticides; and I do declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention has reference to improvements in devices for applying vermin destroying powder to fowls, and consists of means by which the fowls, in passing in and out of the hen-house, sprinkle such powder upon themselves.

The-present application comprises improvements upon the construction for which I obtained United States Letters Patent No. 472,456, on April 5, 1892, by which the mechanism involved is simplified, and made more effective and durable.

I accomplish the above purposes by the construction shown in the accompanying drawings, in which- Figure 1 is a perspective of my invention. Fig. 2 is a detail of the concussive lever and some of its adjacent parts.

Similar letters refer to similar parts in each View.

AA are'standards, seated a certain distance apart on the base S, and drawn partially toward each other at their upper ends, one of said standards having the vertical portion B, and the other of said standards the vertical portion 0 and the diagonally outward projected end D. Between the vertical portions B and O, aforesaid, of the standards A, there is suitably seated, vertically, the insect powder containing vessel E, having its bottom provided with perforations F, suitably distributed over such bottom.

G is a treadle board, either wooden or metallic, pivoted laterally at H to the base S between the standards A, and adapted to oscillate on such pivotal points in the line of the opening between said standards.

R is a double bell-crank lever, pivoted atJ 0n the upper extremity of the part D of one of said standards A. Said lever consists of one long horizontal arm K, extended over the upper end of can E, and provided at its extremity with the concussing head L, the downwardly projecting arIn M, provided at its extremity with the head N, hanging in its normal position about parallel with the adjacent side of the can E, and provided with the short arm 0, substantially in prolongation of the arm K. v

P is a wire, or cord, attached at its lower end to the corner of the treadle G, and extended vertically, and attached at its upper end to the extremity of the arm 0 of lever B.

The operation of my invention is as follows:The' device is placed directly within the opening of the hen-house, in such relation to said opening as that the fowls, in passing in and out of the latter, are compelled to step upon and walk over thetreadle G. The arms K and M are of such weight as to hold the side of the treadle G, to which the wire P is attached, normally elevated a suitable distance above the earth, or floor, of the hen-house. The passage of the fowls over the treadle G has the effect of forcing such wire attached end downward, and thereby, through the medium of said wire, depress the arm 0 of the lever B, and cause the end N of the arm M to strike the part 0 of the standard A, and as said part 0 is in contact with the can E, the concussion of such blow jars said can and causes a portion of the powder contained therein to be sprinkled upon the fowl or fowls beneathsaid can being suspended, as aforesaid, about centrally above the treadle G. The action last described has the effect of raising the arm K above said can,and as the I fowl steps from, and thereby releases the treadle G, the arms M and K conjointly incidentally raise said treadle, which causes the arm K to strike the top of the part B of one of the standards A, and thereby impart asec- 0nd concussion to said can, which will discharge another portion of said powder upon the fowl beneath, before the latter has passed beyond the reach of said falling particles. If preferred, the headsL and N may be arranged to strike the side and top of the can E, respectively; but, to prevent possible damage to said can, I prefer to receive the blow on the standards A, as shown.

The advantage of my present invention is that each Whole movement of the treadle G results in imparting two concussions to the can E, producing two successive discharges from thelatter, and thereby not only increases the quantity of discharge, but distributes the same over different portions of the body of the fowl beneath.

The parts may be made of wood, or metal, or partly of each, as may be deemed most desirable; but, in either event, should be Well coated, or painted, for the purposes of preservation.

That I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. The combination of the vertical standard A, the powder containing can E supported in the upper end thereof, the lever R pivoted at J to upper end of standard A provided with concussive arms K and M diverging from said pivotal point, and an actuating arm 0, the treadle G pivotally seated at the lower portion of said standard, and the rod, or wire,P connecting said treadle with said operating arm 0; substantially as shown, and for the purpose described.

2. The combination of a suitable vertical frame and treadle, seated in the lower portion thereof, and an insect powder containing can seated in the upper end thereof, the lever B fulcrumed in the upper end of said frame, and provided with the concussive arms K and M adapted, in the oscillations of said lever, to. alternately jar said can, and with the actuating arm 0, and means, substantially as shown, for connecting said last named arm and said treadle, whereby the vertical oscillations of the latter are communicated to said lever for the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.

MARY A. HAWLEY.
