VILLIAM FRANK CRAWFORD, OF COLORADO. TEXAS,
V ERMIN-EXTERMINATOR FOR POUIVTRY'.
Specica tion of Letters Patent.
Patented llanZ-"l, 19M.
Application filed.Jux1e 2021910. Serial No. 567.828.
Be it known that I, tiranni l". tutu' FORD', n' citizen of the vUnited States. and a resident of Colorado'. in the county ot Mitchell and State of Tenes, have. ii'nentcd. an '-Improi-'ed Vermin Extcrniinator tor Poultry, owhich t-he 4follcnyingis -a specifcatin:
' My invention is an apparatus adapted for location in, or adjacent to, the doorway' of a poultry-house' or yard, and forapplying to fov'ls, afsy they pass in or ont, a liquid dcstructiveto the vermin with which they may be infected. 4
The apparatus' includes. as chief elements, a. cup-,j-orcan-like holder for the oil or other liquid used as the insecticide. a perforated --oonyje'yer into and from which the liquidis delivered: and a fibrous dlstrlbute'r WithI which the ,fowls' come in contact as they7 pass in or ont. The 'liquid'holder is vprovided Witha Valve for regulating 'discharge into the conifeyer, and the distributer is preferabljr formed of cotton strands that are hungr Vfrom "a piyotedrocking-device in which they are clamped. v
Thedetails of construction, arrangement, and Voperation of theapparat'us are as hereinafter described, and illustrated in the accompanying drawing. in which Flgure l is a perspective View showingr my invention las Suspended and arranged in actual practice. Fig. 2 is a vertical cross section.` Fig. 3 is a detail perspective View of a portion of the apparatus.
A indicates a holder for the oil or other liquid used as an insecticide.,V The saine is supported upon brackets which are rigidly 'attached to"the..f i,t'to of the triangular conveyer B into which tlie liquid is delivered fromV the 'holder A, thebottom of thelatter bein proifided with a Conicel'valve a which is a justed, that istosay opened-orolosed, by means -ofa slidble rod a. lThe elongated conveyer fB has'a. funnel-shaped opening at the top and a' series of perforations o at .the bQt-tom .'as indicated in Fig.' 3. The oilorother liquidtfhus delivered into the yconveyor B run-s -ailonglthebottom and 1s de livered' to -the distributer. C. 'The latter 'is r formed of fibrous niaterialfpreferably 'of cotton or other twisted strands which are suspended fr orn the conveyer B, being -for this -purpose looped over a bar B"that extends beneath and parallel .to the bottom of degree by the derneath said material.
thc conveyor B. ,l`he;,disl*rihntor this tur#` [her secured .between the jaws o-tfa'rlfocltnsr altarjlnncntt." -which is pirotally attach'crl'ti) am! .suspeiulcd frein-the. convey-mfrall.: ll`he part C" is: constructed of two jairswhich are pivotcd together at their 'ends` thus giving the same a trough-like `fori-n.` ot' considerably larger width and depth' than 4theeconnoyer.i3 winch practically arranged Within'it'.- tis shown ,in Figs. 1 and Q. The 'endportions of thc. rodl B on which the strands "of the distributer C are hung' are bent `upwardand secured to the ends of the-oonye-yer. B'and.'
`The operation of the. apparatus will now he understood. In practiee. it is suspended n-or adjacent* to a` doorway or passage through which fowls are accustomed to pass in and out of a house or yard. For con- .reni'encel the suspension may be effected byv means of rigid arms (r2 attached to the inlseeticide holder. asshown in Fin'. l. nails or screws being inserted .through eyes in the ends of the arms.; It is to bc understood.- hoiyerer, that aniy other conrenient means of suspension may be adopted. "The strands of fibrousl material C constituting the distributer thus hang' free in the doorway.' and as the fouls attemptv to pass under it. they 'come in contactarith the strands and thus' a Aportion of the liquid is smeared over them. Thisfoperation is facilitated to a considerable ivotal arrangementot the holder C. since '1t-is adapted -torock or swing siden'ise, ln other Words. bit-the pivotal' arrangement referred to. the fibrous material is practically lengthened, since it swings from a higher point than it'would if theclalnp were fixed and incapable of movingr laterally, and hence also swings more easily lso,thatthc fo'wls meet less resistance while passingr un-V thus applied automatically and effectively' and requires no attention on the part of the. owner. sare to replenish -tho holder n'hcn required'.
The insecticide is:
WhatI claim iszv 1. In an apparatus forthepurpose-jspecified, a' conveyer for liquid insecticide consisting of a box-like Ireceptacle .having con'- vering'sides and a series of perforations' in t e narrow bottom, a rodattached to said; conveyer and extending beneath the same parallel to its bottom, and fibrous material hung upon said rod and thus receivingthe d'ri from the conveyer, substantially'as descri d. .2. In an apparatus for the purpose speci# lfied, the combination with a`conveyer consis'ting of a boxlike'receptaclehaving a 'per'- forated bottom. of fibrous material 'and a suspending ,medium therefor, the -saxnebe ing pivoted on and suspended below the con! neger and thus adapted 'torock laterally,` su stant-ially as described.
3. In'an a-"pa'ratiis for the purpose speci l lied, the com mation with the conveyerfor .insecticide comprising a boxdike' receptacle having a perforatedbottom a rod extending parallelto the bottom, fibrous material loopedl over 'saidbrodand thus, held in p osition to receive the drip from 'the conveyer,
and a clampingdevice supported on the con.
veyei and comprising jaws andv screw-bolts passing through the saine, and ser-ving to clampithe jaws Viipoii the vfibrous material, i
substantially as described. l 4; In fan apparatus for-the purpose speci-` ied, the coni ination-'with 4a. conveyer for 'liquid insecticide, of a trough-like -device suspended therefrom 'and having lower rl tions serving as jaws;,-filuoiis material eld between .the jaws,1and'- c'lariipiiig devices ap-L plied thereto for fibrous material, substantially asdi:,Scifibelli;
