Abstract
APPLICATING PISTON DEVICE
ABSTRACT OF THE DISCLOSURE
The applicating piston device is designed for the botanical and veterinary medical field. It is equipped for this pur-pose easily adjustable dosing means. The dosing means are comprising a dosing wheel, which is rotatable through a vertical axis with respect to the cylinder of the piston and is provided with recesses of varying depth in a radial direction. The dosing rate can be varied by engaging a stepped bar which is attached to the piston handle with one of the preselected recesses in the dosing wheel.

Description
7~
The invention relates to a pistol-type applicator for use in veterinary or bo~anical fields with a piston handle and Q cylinder handhold which are drawn towards each other during application. Such types of pistol applicators are of~en equipped with an adjustable dose-regulating device.
In the known pis~ol applicators the dose~regulating device consists of a setscTew which limits the piston stroke according to the dosage desired.
This has the disadvantage that when changing over to other dosage rates the setscrew has to be set in another position by means of a lengthy procedure.
It has been found that the adjustment of the dosage rate is in practice inconvenient and that the pis~ol applicator is difficult to handle.
The object of the present invention is to create a pistol applicator by means of which the dosage rate can be easily changed over from one setting to the other.
The invention provides in a pistol applicator for use in veterinary or botanical fields and the like and having a piston operator and a handhold which are drawn towards each other during application and a piston cylinder housing, wherein the i~provement comp~ises adjustable dose-regulating means including a dose-regulating wheel fixed to the cylinder housing and rotat-able about the longitudinal axis of the cylinder housing and means de~ining a plurality of notches in the wheel, each having a different ~adial extent and an outwardly tapering stepped crosspiece attached to the piston operator and insertable in one preselected notch at a time, wherein one step of the cross-piece is engageable with the ~eans defining a preselected one of the notches when the piston operator is drawn towards the handhold to limit the stroke of tke piston operator and thereby regulate the dose applied. The design is preferably such that the pistol applicator lends itself easily to production by means of injection moulding in order to allow cheap large scale manufacture.
The wheel is advantageously provided with cams which engage with co~responding grooves on the cylinder, thereby preventing twisting of the cylinder and effecting exact positioning o~ the regulating wheel.
.~ .
For the purpose of the innovation the dose-regulating whe~1 has engaging grooves which correspond with the no-tches of varyingdepths, In this way a quick and convenient se-tting of the desired dosage rate is made possible.
A further advantage of the innovation is that the pis-tol applicator lends itself easily to produc-tion by means of injection moulding. A set of dose-regulating wheels can be made available for the user, which are appropriately made for -the various indications. There is -thus no longer the need, as has so far been established, ~or dif~ering pistol applicators for differing types of usesO The main uses in the veterinary field are transcutaneous (spot-on), oral or ; rectal forms of administration of solutions or suspensions to domestic animals of all species.
In the following an example of an embodiment of the innovation is described in greater detail with the help of illustrations.

Figure 4 shows the dose-regulating wheel in detail The pistol applicator shown in Figure 1 is a modified version of a commercially available piston applicator with two ball valves. The device is set in operation by means of suction achieved with the aid of a piston handle 2 attached to the piston 10 By pulling the piston handle the liquid which is to be applied is sucked in via a suction feed pipe 3 ~rom a supply container (not shown) and is ejected through the mouthpiece 4. The pistol applicator can be fixed directly to the supply container by means of the screw cap 5. The ball 3o valve 6 prevents the liquid running back when the piston handle
- 2 -2 is pulled~ By means of the pressure spring 7 inside the piston chamber the piston 1 is pushed back into the starting position after application is completed, while the ball valve in the piston handle closes~
The dose~regulating wheel 9 is arranged at the front end of the cylinder casing 8. It is turned at right angles to the axis of the cylinder and has notches 10 (see Fig. 4) of varying heights arranged in a radial direction. The dose-regulating wheel 9 is provided with engaging cams, there being one engaging groove to correspond with each notch 10.
When the dose-regulating wheel turns one engaging groove comes into action when the corrèsponding notch 10 moves in a direction at right angles to the mouthpiece 4.
A stepped crosspiece 11 is attached to the piston handle 2 above and below (see Figs. 1~ 2, and 3). As the piston handle 2 is pulled the crosspiece 11 pushes itself into the preselected notch 10 until the corresponding step rests on the base of this notch. The notches 10 thus form in combination with the crosspiece 11 a variable arresting surface for limiting the piston stroke. The heîght of the notches 10 is determined by the piston stroke as is at -the same time the application amount. As can be seen from Figure 2 the individual positions are calibrated in ml according to the volume of the application.
The cover plate 12 and piston 1 are provided with a slot-cam-guide in order to prevent the piston 1 revolving around the axis of the cylinderO This ensures that the crosspiece 11 attached to the piston handle 2 always ali~ns with the pre-selected notch 10 in the dose-regulating wheel 9O
For the application of solutions and suspensions the pistol applicator is screwed on to the supply bottle by means of ~L~D7~
the screw cap 5. m en the desired application amount is set by turning the dose-regulating wheel 9. Application then takes place, as already described, by pulling the piston handle 2 (see Fig~ 2). The pistol applicator has such manageable dimensions that it can be operated wi-th one hand:
while the piston handle 2 is pulled the palm of the hand rests on the rear cylinder handhold 13
