while a suction effect simultaneously takes place.
The present invention has for its object to provide an injection apparatus which makes it possible to pull the needle out of the ground after the injection by exerting a comparatively weak traction force on the apparatus.
This apparatus comprises a handle of a conventional type terminating in a needle also of a conventional type, but instead of being rigidly secured to the handle in the heretofore commonly used manner, the needle is slidably mounted, and. a stop device of a kind which is known per se is provided and arranged so as to allow only a small amount of longitudinal relative sliding movement between the needle and the handle.
By virtue of this arrangement when the operator pulls on the handle of the apparatus in order to pull the needle out of the ground after the injection, the handle first rises without the needle following its movement since the sliding arrangement becomes operative at this moment; when the sliding movement of a few centimetres is achieved the stop enters into action and gives rise to a shock which considerably facilitates the pulling out of the needle, since the momentum stored in the movement of the handle reduces the strength which is necessary for the operation. When driving the needle into the ground it is also possible to facilitate the operation by striking against the needle with the body of the apparatus.
A form of execution of such an apparatus is shown by way of example in the appended drawing.
In this drawing:
Fig. 1 is a partial side view of such an apparatus showing the lower portion of the handle and thedevice for fastening the needle.
Fig. 2 is a front view of the same.
Fig. 3 is a bottom plan view showing the arrangement of the strap around the needle, and
Fig. 4 is an elevational view, some parts being, broken away, showing a modification of the fastening device.
Referring to the drawing, the apparatus shown comprises in a manner which is known per se, a
tubular handle .I whichmay carry the liquid-discharging members andwhich is provided towards its .lower .part with a transverse bar 2 adapted to'be engagedbyzthe foot when driving the needle into .the ground. The hollow needle 3 which is here shown as a conical needle is provided with an extensionsuch as the .rod 4, which -is slidably .mountedin-the lower part 5 of the handle. To the hollow part of the needle there is connected at .6 a flexible liquid supply conduit T and .below this conduit two shoulders 80, and 8b are arranged.
A strap 9 provided with two U-shaped rods l0, II is mounted by means of said rods on the bar 2 around which it rocks. This strap is provided with a notch 12 the width of which is larger than the diameter of the needle at its base but smaller than the diameter of the shoulders 8a and 8b and the thickness of the strap is smaller than the distance between said shoulders. The length of the rods l0 and H is such that when shoulder 8a is in contact with the strap 9 the rod 4 is still sufficiently engaged in the tube 5 of the handle to insure the rigidity of the Whole.
The device works as follows:
When the operator starts to drive the needle into the ground, the rod 4 moves deeper into the tube 5 and the part 6 of the needle strikes against the tube 5, while the shoulder so raises the strap with respect to thebar 2. When the operator pulls on the handle after the injection to draw the needle out of the ground, the rod 4 slides in the tube and the needle does not follow the movement; when the rod 4 has thus moved a few centimetres the strap 9 suddenly strikes against the shoulder 8a and the momentum stored in the handle is then suddenly transmitted to the needle which is thus drawn out of the ground.
To remove the needle, for instance for the purpose of replacing it by another, one only has to rock the strap 9, H], II into the position'shown in broken lines in Fig. 1.
As shown in Fig. 1, the rod 4 is screwed at 13 into the part 6 and is provided with a fiat I4; this arrangement makes it possible to unscrew the rod to separate it from the needle unit for cleaning and unstopping the latter; indeed, if such a dismounting were not possible, a cleaning of the bore of the needle would also not be possible since the supply of the liquid takes place on the side.
In the modification shown in Fig. 4 the liquid is no longer supplied on the side; the rod forming the extension of the needle is substituted by a tube [5 terminating in a nipple on which is secured the flexible tubing [6 connecting the needle with the liquid-discharging members; said tubing extends up into the handle of the apparatus to the upper part thereof. It is then the elasticity of the tube which renders possible the sliding movement of the needle; such an arrangement ofiers the advantage of ensuring the return of the needle when the operator efiects no traction upon the handle, besides eliminating the outer pipe I.
This arrangement can be adapted to any kind of injector stake provided with a needle of any design.
ments between the needle and the handle when said connecting member is in engagement with said needle.
2. An injection apparatus according to claim 1 in which said connecting member comprises a strap having a notch the width of said notch being greater than the diameter of said needle but'less than the diameter of said abutment,
, said strap being provided with two U-shaped It is obvious that the construction of the slidinjection needle having an extension bar slidable in said recess, spaced abutments on said needle adjacent the upper end thereof, and a connecting member pivotal1y fastenedto said handle so as to be selectively engageable and disengageable-with said needle in the region between said abutments, and adapted to cooperate with said abutments to limit the relative sliding moverods said rods passing around a transverse bar secured to said handle.
