Abstract

Detonating primer cords for explosives are usually stored and dispensed from a reel sometimes contained in a cardboard box or the like. The present dispenser or container receives the reel upon a spindle and is mounted for free rotation upon a base support. The cord feeds through an aperture in the front wall of the container so that when the cord is pulled to dispense same, the container pivots upon the base so that the cord can be pulled out readily and easily. The dispenser is made of non-ferrous material to prevent electrical sparking from occuring thus adding to the safety of the dispenser.

Claims

1. A dispenser for explosive primer cord and the like which is wound upon a reel having a transversely extending central bore;

comprising in combination a container and a base, means mounting said container upon said base for free rotation in a plane parallel to said base, detachable spindle means in said container to receive the associated reel and to mount same for free rotation upon said spindle and a cord dispensing aperture in one wall of said container, said container including a rear wall, a front wall, a base plate and a pair of side walls forming a substantially cubicle container and at least one selectively detachable spacer plate engaging within said enclosure between one side of the associated reel and one of said side walls of said container, said spacer plate having a substantially vertical slot extending upwardly from the lower edge of said spacer plate and terminating spaced from the upper edge of said spacer plate, said slot engaging said spacer plate over said detachable spindle means, said spacer plate having a configuration similar to one of said side walls but with the upper edge of said spacer plate extending above the upper edge of said side wall when said spacer plate is engaged within said container, said spacer plate being removed by grasping said extending upper edge.

2. The dispenser according to claim 1 in which said base includes a substantially cylindrical component and a flexible tire-like rim surrounding said component and engaging the surface upon which said base rests.

3. The dispenser according to claim 1 in which said means mounting said container upon said base includes a support secured to the underside of said container and extending downwardly therefrom, bearing means in said base, and bolt means detachably connecting said bearing means to said support.

4. The dispenser according to claim 2 in which said means mounting said container upon said base includes a support secured to the underside of said container and extending downwardly therefrom, bearing means in said base, and bolt means detachably connecting said bearing means to said support.

5. The dispenser according to claim 1 in which said side walls include means to detachably mount said spindle means across said enclosure, said means comprising a substantially vertical slot formed in each of said side walls with the upper ends of said slots opening into the upper edges of said side walls, the lower closed ends of said slots inclining forwardly and downwardly, said spindle engaging within the said lower closed ends.

6. The dispenser according to claim 2 in which said side walls include means to detachably mount said spindle means across said enclosure, said means comprising a substantially vertical slot formed in each of said side walls with the upper ends of said slots opening into the upper edges of said side walls, the lower closed ends of said slots inclining forwardly and downwardly, said spindle engaging within the said lower closed ends.

7. The dispenser according to claim 3 in which said side walls include means to detachably mount said spindle means across said enclosure, said means comprising a substantially vertical slot formed in each of said side walls with the upper ends of said slots opening into the upper edges of said side walls, the lower closed ends of said slots inclining forwardly and downwardly, said spindle engaging within the said lower closed ends.

8. The dispenser according to claim 4 in which said side walls include means to detachably mount said spindle means across said enclosure, said means comprising a substantially vertical slot formed in each of said side walls with the upper ends of said slots opening into the upper edges of said side walls, the lower closed ends of said slots inclining forwardly and downwardly, said spindle engaging within the said lower closed ends.
