Letters Patent No'. 109,762 dated November 29, 1870.
IMPROVEMENT IN.l INSECT-POWDER EJECTRS.
The Schedule referred to in the-seLetters Patent and making part of the same.
Nature and Objects of Invention.
Our invention consists in certain improvements in the construct-ion of an apparatus for ejecting and'V directing vermiu-exterminating powder, for which Letters Patent were issued to Moritz Koppe, September 7, 1867, and these improvements lie in the provision of a detachable bottom for the powder-can,andthe arrangement of the elastic diaphragm, which-is retained in place by a clamping-ring, so that the several parts of the device may be easily. separated forcleaning them, or for repairs.
Description of the Accompanying Drawing.
Figure l is a vert-ical central section of a powder-v ejector, embodying our invention.
Figure 2 is a perspective view of the same.
. Gcncrcl Description.
A is the body of the machine, or exterior case, andV B, a detachable bottom.
'lhe case is of tapering form on the sides, and hemispherioal on top. It can he struck up by dies, or spun, and any preferred lmaterial can be used.
The lower part of the case is screw-threaded. outside, and connects with the female screw provided in bottom B.
A pipe, O, is soldered, or otherwise secured to the ease, for giving direction to the powder blown out.
A stopper, D, is fitted to the hole b, through which the case is supplied with-powder. v
A diaphragm, of leather, canvas, or other iiexi-ble material, E,'is secured to the case A by means ofthe solid ring F, which, owing to the tapering form of the case A, rlnly secures t-he diaphragm by crowding the edges of the same tightly between the case and ring F, when the latter is forced into place.
The diaphragm is designed to havea reciprocating motion, for the purpose ot'ycompressing the air in the case A suiiciently to force out the powder. This luotion is accomplished by the thumb-knob Gr and stem H in 'one direction. and by the coiled spring I in the other.
The stem H passes through an aperture in the upper part of the case A, and connects to the diaphragm by means of plates, h h, and nut h".
The spring I is soldered, or otherwise fastened to the plate 71.'.
' Operation.
The powder is placed in the case A through the opening b, and the stopper Dtitted in, to close the same. 4
A slight pressure of the hand upon the knob Gr against the action ofv the spring I, serves to so compress the air contained in the case A as to expel a portion of the powder from the case A through pipe C, the latter serving to direct the powder into cracks, joints, and crevices, with considerable force. Upon t-hewithdrawal of the pressure from the knob Gr, the spring retract-s and elevates the diaphragm E, the chamber being supplied with air through the pipe O at the same time. It'.the apparatus should at any time need repair, the whole can be'easily separated by the unscrewing oi' bottom B and knob G,
Claim.
The improvement in insect-powder ejectors, herein described, consisting of a detachable bottom, B, for the case A. andthe arrangement ot' the elastic diaphragm E, so 4as to be retained in place by a clamping-ring, F, whereby the parts constituting the device can be easily separated for repairs.
In testimony ot' which invention we hereunto set our hands.
SALOMON ROSE.
