Referring now more particularly to Figure 1, the ref-' erence numeral .10 indicates ingencral the housing forming the main'body portion of the artificial insemination gun and which housing is of gun-shaped configuration including thehand-grip portion 11 and the upper frame vided with a trigger element 13 which, upon actuation, injects a predetermined quantity of inseminating fluid from the nozzle portion 14 located at the forward upper end of the gun, as shown. Preferably, the housing assembly is formed of commercial plastics or'other easily moldable material, for ease and economy of manufacside portions "17 and 18, see particularly Figure 4, which Another object of this invention is to provide an improved artificial insemination gun in accordance with the precedin'gparagraph wherein the complemental half-sections are also provided with a rectangular recess and, intersecting therewith, a further recess, the latter of which houses a ratchet wheel and pinion assembly and the former of, which guidably and slidably receives a trigger ture, and the upper forward portion of the gun is. provided with a dust cover or shield indicated generally by the reference character 15 and which includes the cover or cap portion 16 disposed above the gun and the opposite have associated therewith screw elements 19 and 20 so as to pivotally attach the shield to the gun body so as to be swung from the normal-full line position as shown in Figure 1' to an out of the way position such as is illustrated in dotted lines in Figure 1. The rearward end of the cover portion '16 is provided with a tongue element 21 extending rearwardly therefromand which normally rests upon the upper surface of the housingdfl and pivotally attached to the housing is a U-shapedwire- Patented Junev 28, 1960v taken substantially along of Figure 2 and along the sections 23 and 24 which are similarly formed, and provided as hereinafter set forth, with certain registered, recesses, openings and the like forming certain pockets and bores within the housing to receive the component parts of the mechanismforming this-invention. These complemental half-sections are joined together with a plurality of screw fastening devices 25 and each ispro-- vided with a fiat inner face which define the parting surface between the half sections when joined together.
Figure 3 illustrates the manner in whicheacht of the complemental half sections is. formed, and in this figure, it is to be noted that each of such sections is provided with a recess 26 which extends and opens at the forward,
end of the gun at 27 and extends rearwardly therefrom opening into a transverse slot or opening. 23 in each section. The transverse opening 28 extends between the opposite end walls 29 and 30 thereof and, see-particularly Figure 4, the recess 26 in each half section is provided with an arcuated bottomportion 31 and with tangentially vertical side wall portion 32 extending upwardly to the upper wall surface 33 thereof and when. the two halfsections are joined, the recesses 26 form the bore as illustratecl in Figure 4 and the openings 28 provide a transverse slot extending from side-to-side of the housing in the upper central region thereof.
Within each of the recesses 26, is formed a notch 34 for receiving the flange portion 35 of a syringe cartridge 36. The syringe cartridge extends forwardly through the bore provided by the two recesses 26 to the forward end of the gun as is shown in Figure 3 and terminates in a nipple portion 37 which is joined to the previously mentioned nozzle 14 by means of a flexible sleeve 38, the purpose of which is to permit flexing of the nozzle 14 relative to the gun to avoid injury to the poultry on which the gun is being used.
The top edge lip 39 (Fig. 4) provided in each com-' plemental half-section by the associated recess 26 is utilized as a supporting base for a pair of battery elements 40 and 41 by means of which a heating element 42 is powered. The heating element includes an outer casing 43 and, disposed therewithin, a resistance unit 4-14 which is connected at its opposite ends through the flexible conductors 45 and 46 to the batteries 40 and 41 so as to generate heat fromthe energy supplied by the batteries to maintain the inseminating' fluid within, the cartridge36 at the proper, temperature. In this. respect, it is to be noted that the heating element is, disposed in physical contact with the cartridge 36, see Particularly Figure 4, and isv disposed within the bore provided between the recesses 26.
For the purpose of, mounting the batteries 40 and il,
the housing is provided with the upstanding posts 47 and:
48 which carry contact members 49 and 50 to which the conductors. 45 and 46 are connected. The batteries 40 and 41 are disposed between these posts 47 and 48 and are connected in series aswill be readily'appreciated.
The previously mentioned cover portion 16 of; the
shield completely encloses the batteries 40 and.v 41, and.
provides a housing therefor at the upper portion of' the gun and the side portions 17 and 18 of. the shieldextend downwardly on opposite sides of, the, gun; and: normally" Thus, the shield acts asa dust protector to prevent the. entrance of. foreign material into the working. parts of the gun and. at. the same; time provides at readymeans by.-whichv the syringe mechanism, or atleast; thepiunger 51 thereof may be viewed. Also, the plunger, which projects into the cartridge 36 in a well known manner, may be manipulated by the operator through the transverse opening in the housing as provided for by the transverse openings 28.
Each of the complemental half sections is provided, in the trigger region of the housing, with a generally rectangular recess 52 which has a corner thereof opening exteriorly of the, housing and these recesses form a rectangular pocket within a housing to accept the previously mentioned trigger element 13 as will be clearly seen in Figure 3. This'trigger element is of generally rectangular configuration to correspond in height to the dimensions of the pocket defined by the recesses 52 but is of less width than such pocket so that the rear edge 53 of the trigger is normally spaced from the opposing surface of the pocket as will be clearly seen. Each of the sections is also providedv with a trough 54 which extends horizontally from the forward portion of the gun rearwardly and has an extension 55 on the opposite side of the recesses 52 so as to provide a bore to receive the guide rod 56 which projects through the trigger element 13v and normally retains the same in guided relationship within the housing. The guide rod 56- is preferably pinned as at 57 to the housing half-sections.
The guide rod also serves as a means for locating a compression. spring 58 which serves to locate the trigger element 13 in, the normal position shown in Figure 3.
The trigger, at the upper end thereof, carries a pawl 59 which extends rearwardly therefrom toward the upper rear corner of the recesses 52 and into a further recess 60 which intersects the recesses 52 in the upper corner portion thereof as is shown. The recesses 60 provide, in the housing, an inner pocket housing the ratchet wheel andpinion, assembly indicated generally by the reference character 61.
The assembly 61 includes a ratchet wheel 62 which is engaged by the pawl 59 and which is rotated in step-bystep fashion in response to actuation of the trigger 13. In addition, the assembly 61 includes a pinion 63 (Fig.
together and rotatably received on an axle element 64 which-extends through the two complemental half-sections as shown. Since the ratchet wheel 62 is located substantially wholly within the confines of the half-section 24, such half-section carries a stop pawl. 65 which normally serves to prevent retrograde rotation of the ratchet wheel 62 as will be readily appreciated.
Each of the half sections is also provided with a further groove 66. which extends into intersecting relationship with the inner recess 60 and has a continuation 67 thereof at the forward side of such recess and which extension intersects with the transverse openings "28 and within the bore, provided by these complemental grooves, is a rack element 68, having the downwardly facing teeth 69 which are engaged with the teeth of the pinion 63' and which rackcarries atv its outer end a head element 70 engaged against the rearward end of. the plunger 51 of the syringe mechanism. In this manner, it will be readily apparent that actuation of the trigger mechanism 13 rotates the. ratchet wheel, and pinion assembly to urge the rack forwardly step-by-step whereby to progressively operate the plunger 51.
Inorder to control the motion imparted to the plunger 51', and consequently to provide a control of the amount ofinseminating fluid 71 dispensed from the-cartridge. 36, a setscrew 72 is providedbetween the half- sections 23 and 24, the same being provided with-complemental threaded grooves 73 so that the inner end 74 of the setscrew may be located in proper proximity to the rear edge 53 of the trigger element 13 so as to limit its extent of. travel.
From the foregoing, it will be readily apparent that the complemental half-sections provide a convenient; and economical means of presenting suitable pockets, bores nd-the i e ithin the housing assembly 10 so as to re-- ceive the various component operating portions of the inseminating gun. As previously discussed, it is possible by swinging the shield 15 out-of-the way to reach through the opposite sides of the housing and manipulate the plunger 51, as desired. In this way, the syringe mechanism may be refilled with inseminating fluid and the operator has at all times means by which he may visually gauge the amount of inseminating fluid left in the syringe mechanism.
Inorder to change the syringe assembly in the gun, all that is necessary is to remove the shield and then to remove the fastening elements 25 securing the two complemental half-sections together, after which the syringe mechanism is fully exposed and will be permitted of withdrawal from the assembly.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur' to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown 1 and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed. a
What is claimed as new is as-follows:
1. An artificial insemination guncomprising a pistolshaped housing composed of a pair of complemental sections removably secured together, each of said sections having a transverse opening therethrough and a first recess intersecting such opening and extending therefrom to and opening upon the forward end of the housing so that the housing is provided with a bore extending inwardly from the forward end thereof and a transverse slot intersecting said bore, .each section also having a second recess therein of rectangular configuration having an open corner portion thereof disposed in the trigger region of the housing and each section further having a third recess therein intersecting the second recess diametrically of the open corner of the second recess so that the housing is provided with inner and outer pockets communicating exteriorly thereof in the trigger region of the housing, a
7 generally rectangular trigger slidably disposed in said outer pocket, a ratchet wheel and pinion assembly journalled in said inner pocket, a pawl carried by said trigger engaged with said ratchet wheel forrotating the same, each of said sections having a groove extending through said second recess and intersecting said transverse opening providing a secondary bore in said housing, a rack slidably received in said secondary bore in engagement with said pinion and projecting into said transverse slot, a syringe disposed between said sections including a cartridge received in said first mentioned bore and a plunger reciprocable in said cartridge and extending therefrom into the transverse slot and into contact with said rack,
whereby actuation of said trigger will operate said' plunger.
2. The assembly defined in and by claim 1 including a second groove in each of said sections and intersecting the upper portion of said second recess and having a continuation thereof on the opposite side of such recess, and a guide rod received in such grooves and extending through said trigger to guide the same.
