RECEPTACLE FOR CONTAINING AND DISCIIARGING SEMISOIJD AND PAS'IY SUBSTANCES.
Application filed October 14, 1910- Serial No. 587,084.
To all whom it may concern:
Be it known that I, JAMES F. CRAVEN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have in-' vented a new and useful Improvement in Receptacles for Containing and Discharging Semisolid and Pasty Substances, (Case 5,) of which thezfollowing is a specification. This invention relates to receptacles for containing, storing, transporting and discharging semi-solid and pasty substances.
The device is intended more particularly for putting up lubricants in the form of grease and discharging the same into grease cups of machines or the like, and for the purpose of enabling grease to be supplied to thebearings without liability of dirt or grit entering the bearing with the grease, and also to prevent smearing up orsoiling the machine or the hands of the user. The invention, however, is not limited to this particular use, but is adapted for putting up .desired material.
in a substantially sealed condition any semisolid or pasty substances and delivering the samefrom the container in any desired quantity or quantities.
The invention comprises the construction and arrangementof parts hereinafter described and claimed.
In the accompanying drawings Figure 1 is a vertical section through one form of the device; Fig. 2 is a similar view showing a modification; and Fig. 3 is a cross section on the line 4-4, Fig.2.
The container or receptacle may be of any desired size or shape and may be constructed or built up in any desired way or from any As shown, the body ,of the receptacle is formed as a substantially cylindrical tube 1 which may be of sheet metal or other thin substance, and is shown as formed from paste or paper board in Fig. 2, and from sheet metal in Figs. 1 and 3. One end of this receptacle is entirely open but the contents are protected by means of a piston or follower 2 which is longitudinally movable in the receptacle and serves to force the material out of the same, said piston preferably having a cup leather or like eX- pansible means to form a tight fit in the tube, said cup leather being yielding so as to maintain a tight fit in the tube in case the latter expands under the pressure of forcing out the substance contained therein. The discharge orifice is at the end of the 'tating the rod 14 in tube, opposite its open end, said discharge end being provided with a head or cap closing the same. As shown in Fig. 2, said end is closed by means of the head or cap 4 which is crimped onto the paper body-1.
The head or cap 4 is provided with a dischargeorifice 7 leading to a short discharge sleeve or tube 8 which is externally threaded to receive the threaded closing cap 9, and also for the purpose of having secured to the discharge orifice a spout or the like for delivering the material, such as grease, to a machine bearing or the like. 4
The piston 2 is shown as a metal cup provided with a central threaded sleeve 12 for receiving a threaded rod or screw 14 which I when rotated causes the piston to travel longitudinally in the tube. The means for ro- Fig. 2 comprises a transverse shaft or key 15 extending through the outlet sleeve 8 and provided at its end with a loop or thumb piece 16 by means of which it can be rotated. Said transverse shaft or key 15 is operatively connected with the threaded rod 14 by means of inter-meshing bevel pinions 17, which are held in mesh by means of the bracket 18 forming bearings for the transverse shaft 15 and also for the threaded rod 14. The operation of this device will be readily understood.
In Fig. 1 the piston 2 is likewise moved by means of a threaded rod 14 which at its outer end is connected to the head or cap I 19, which in this case is rotatable on the body 1 but lengthwise immovable with reference thereto, such as by turning its'edge 20 underneath an annular flange or shoulder 21 on the tube 1. The annular edge of the cap 19 is preferably knurled, as shown at 22, to afford a good grip when turnin the same. The projection 8 in this case is c osed at its outer end except for one or more dis-. charge orifices 7 a plurality of such orifices being preferable on account of the screw rod 14 being attached cent-rally to the end of projection 8.
\Vith the form of device shown in Fig. 1 the contents are discharged by holding the tube 1 in one hand and rotating the cap 4 with the other hand, while with the form shown in Fig. 2 the contents are dischargedby holding the tube in one hand and turn: ing the key 15 with the other hand. The piston in Fig. 1 is prevented from rotatin by means of the seam 24 on the sheet metal v at all times "is substantially sealed or at least tightly closed so that the contents are protected fromdirt and odors, and the contents can be discharged therefrom-without liability of soiling the hands, and in a small stream so that, in the case of lubricating grease, the grease can begotten into the machine cups without danger of carrying dirt or grit with the same. 1
The receptacles will be filled and closed at the factory, and since there are no pro nounced projecting parts they can be conveniently and safely packed, transported i and stored. The means for discharging the I contents does not provide any undue projections beyond the casing and this also facilitates packing-and storing. v
The receptacle is intendedto be used only once, being filled at the factory and thrown away when empty. Hence it mustbe of low cost, and is'necessarily made of cheap and comparatively weak material and with minimum labor operations. A paper or paste board tube is therefore preferred for the body of the receptacle, but if sheet metal is used itwill bejof the thinnest gage. On ac count of the cheap and light construction of the tube it is liable to expand slightly or assume a slight barrel shape under the pressure of forcing a stifi g'rease out of the same.
The cup leather 8 however is expansible and: forms in effect an 'expansible piston or follower and maintains a tight fit against the inner face of the tube and prevents the 4 ceptacle and thereby rotatable but endwisc.
immovable thereon and having thereon-a tubular extension provided with a discharge orifice, a piston in said receptacle and movable thereinto force the contents through the discharge orifice, and a threaded mcmber secured to said cap and operatively engaging said piston.
A device of the character described, comprising a Weak tube, a cap closing one end thereof and provided with a dischar e orifice, a piston in said tube and longitur inally movable therein to force the contents out of the discharge orifice and provided with a yielding portion cupped toward the discharge orifice, a threaded member engaging said piston and endwise immovable in said tube, and means on the end of the tube at which is the discharge orifice for rotating said threaded'member.
3. A. .device of the character described comprising a weak tube, acap having a my hand.
