INVENTOR ROGER W. MARTYN BYMm/w fldz f/ mToRNEYs Patented Oct. 28, 1952 UNETE MACEHNE FOR CHARGING DETGNATDR CARRYING PLATES Application February 10, 1949, Serial No. 7,427 In Great Britain March 19, 1947 The present invention relates to machines for charging a. detonator carrying plate with empty detonator tubes.

The object of the present invention is to provide a machine which permits a detonator carrying plate to be charged with empty detonator tubes in a simpler and more convenient manner than heretofore.

According to the present invention, the machine for charging a detonator carrying plate with empty detonator tubes comprises, in combination means for holding a removable detonator carrying plate in position, a slidable feed plate adapted to rest on the detonator carrying plate held in said position and having holes which taper towards the bottom face thereof and correspond in position to those in the carrying plate, a row of detonator tube guide-tubes positioned above the feed plate and adapted to be inclined at a variable angle to the vertical, e. g. 10 to the vertical, and means permitting the slidable feed plate and carrying plate when their respective holes are out of alignment to move together below the row of guide-tubes, in which machine the slidable feed plate is adapted to slide laterally across the carrying plate between two limits so that in one extreme position the holes of the plates coincide and in the other position they do not coincide and in which the row of guide-tubes when inclined at a suitable angle to the vertical is at such a distance from the slidable feed plate as to permit the detonator tubes projecting from below them to slide over those that have fallen into the holes of the feed plate onto the top of the carrying plate.

The machine according to the invention and the manner in which it is to be used will now be described by way of example with reference to the drawings accompanying the specification in which:

Figure 1 is a cross-sectional view through a vertical plane along the length of the machine showing the holes of the slidable feed plate and detonator carrying plate out of alignment;

Figure 2 is a vertical sectional view at right angles to Figure 1 showing only one of a series of feed tubes in a row for simplicity of illustration;

Figure 3 is an enlarged fragmental view of Figure 1 at a later stage of operation;

Figure 4 is a cross-sectional view similar to that of Figure 2 at a later stage of operation of the machine than shown in Figure 3; and,

Figure 5 is a plan view of the machine of this invention.

2 Ciaims. (Cl. 8648) Referring to'the drawings, l is one of a row of guide-tubes inclined, for example at an angle of 10, to the vertical in the direction shown, down which are fed, in known manner, the empty detonator tubes Ll so that there is formed in each guide-tube a continuous column of detonator tubes with their closed ends facing downwards. Ihe guide tubes l are free to rotate about ahorizontal axis through their lower pivotal support 9 and may be held at the desired angle to the vertical by a clamp H3 which locks the upper support H in position. The slidable feed plate 2 rests upon the detonator carrying plate 3 so that the tapered holes 5 in the slidable feed plate 2 and the non-tapered holes 6 of the carrying plate 3 are out of alignment. The tapered holes 5 correspond in number and in arrangement to the non-tapered holes 6. The combined plates 2 and 3 rest on a table or bench E2 on which are guides l3 arranged to align the holes 5 in the upper plates 2 relative to the guide tubes I. The tapered holes 5 are wider at the top face than the bottom face of the slidable feed plate, the width at the bottom being a shade greater than the width of the holes 6 of the detonator carrying plate. The row of guidetubes l'is parallel to the rows of holes 5 in the guide plate 2. When-the machine is brought into action, the lowest detonator tubes l of the column of detonator tubes in the guide-tubes l rest on the top of the slidable feed plate 2 but as the slidable feed plate 2 and the detonator carrying plate 3 are fed under and across the row of guide-tubes l by the action of the ram or thruster i i in due course the lowest detonator tubes 4 come above the corresponding tapered holes 5 in the slidable feed plate 2 and drop into these holes onto the top of the carrying plate so that the whole column of detonator tubes drop down in each guide-tube l until the base of each emerging second lowest detonator tube is stopped by the top of each lowest detonator tube from reaching the feed plate.

011 further movement of the combined slidable feed plate 2 and detonator carrying plate 3 owing to the fact that the guide-tubes l are inclined, the lip l of each detonator tube t already in the slidable feed plate 2 bears on the rounded base of the detonator tube above it and raises the latter so that the combined plates 2 and 3 are not prevented from moving onward. Should the guide-tubes i be vertical or insufficiently canted, the lip l of the lowest detonator tube will bear on the vertical wall of the detonator tube above it and jam the machine.

On further movement of the combined plates 2 and 3 the base 8 of the second lowest detonator tube slides over the lip l of the lowest detonator tube and falls until it comes to rest on the top surface of the slidable feed plate 2, ready to fall into the next tapered hole 5 to be presented to I the guide-tube.

When all the tapered holes 5 in the slidable feed plate 2 have been filled, a friction bar which is not shown in the drawings since it forms no part of this invention holds the lowest of the detonator tubes 4 still in the guide-tubes l, and the plates 2 and 3 move on.

The slidable feed plate 2 is now pushed laterally across the detonator carrying plate 3 by means of a second ram or pusher [5 until the two sets of holes 5 and 6 correspond so that the detonator tubes 4 drop into the holes 6 of the detonator carrying plate 3. The slidable feed plate 2 is now removed and detonator tubes 4 in the holes 6 of the detonator carrying plate3 are ready to receive their explosive charges.

I claim:

1. A machine for charging a detonator carrying plate with empty detonator tubes comprising incombinationmeans for holding a removable detonator carrying plate in position, a slidable feed plate adapted to rest on the detonator carrying plate held in said position and having holes which taper towards the bottom face thereof and correspond in position to those in the carrying plate, a row of detonator tube guide-tubes positioned above the feed plate and adapted to be .4 inclined at a variable angle to the vertical, and means permitting the slidable feed plate and carrying plate when their respective holes are out of alignment to move together below the row of guide-tubes, in which machine the slidable feed plate is adapted to slide laterally across the carrying plate between two limits so that in one extreme position the holes of the plates coincide and in the other position they do not coincide and in which the row of guide-tubes when inclined at a suitable angle to the vertical is at such a distance from the slidable feed plate as to permit thedetonator tubes projecting from below them to slide over those that have fallen into the holes of the feed plate on the carrying plate.

2. A machine for charging a detonator carrying plate with empty detonator tubes as set forth in claim 1 wherein the preferred variable angle of a roW of detonatorTtube guide-tubes is 10 to the vertical.
