Nov. 22, 1949 H. c. LIMA LOADER FOR REvoLvERs Filed Feb. 24, 1948 lll Patented Nov. 22, 1949 UNITED STATES PATENT OFFICE Application February 24, 1948, Seral'No. 10,244 In Cuba March 25, 1947 1 Claim.

This invention relates to loaders for revolvers, and it has for its object to provide certain improvements in the loader for revolvers which were the subject-matter of my prior United States Patents No. 2,406,231 and No. 2,406,232, dated August 20, 1946.

Another object oi the invention is to provide an improved loader whereby the reloading and cooling of a revolvers chambers must not necessarily be effected at the same time, but both operations can be performed independently or simultaneously at the users will.

A further object of the invention is to provide an improved loader structure that will increase the degree of efliciency of the loaders operation, and wherein the cartridge receiving cylinders have their walls incomplete and the central cylinder is of a diameter slightly smaller than the diameter of the cartridge receiving cylinders and its wall is slightly thicker than as heretofore provided, whereby a greater sliding area and a safer positioning of the cartridge holding pins are attained.

For a better comprehension of the invention, reference will be had to the figures of the accompanying drawings, in which:

Fig. 1 is an outer elevational view of the improved loader of my invention.

Fig. 2 is a partly broken away top plan view of same.

Fig. 3 is a longitudinal vertical section view on line 3 3 of Fig. 2, showing the position in which the cartridges are held but no lubricating oil is discharged.

Fig. 4 is a similar section view of same, in the cartridge release position.

Fig. 5 is a similar section view to Fig. 3, showing the position in which the lubricating oil is discharged.

Fig. 6 shows two perspective views of one of the cartridge receiving cylinders.

Fig. '7 is a view showing the arrangement and outlines of the stems for actuating the cartridge holding and lubricating oil discharge mechanism.

Fig. 8 illustrates a modiiied form of the loader, unprovided with the lubricator-cooler mechanism.

Fig. 9 is a bottom plan view of the loader.

In the drawings, the numeral I indicates the central hollow cylinder of the loader, the top end of which has its edge provided with equidistant slots 2 having a bevelled bottom, said edge being partly bent inward to form flanges 3l adapted to serve as stops for a disc 3 having a central perforation 4 through which passes a hollow stem 5 having its top end secured to a disc 5 above said cylinder I, the latter having a thickened bottom portion 'I provided with an inner recess 8 and an axial perforation 9.

To the central cylinder I are secured a plurality of hollow incomplete cartridge receiving outer cylinders I0 all parallel to the central cylinder I, which can be made separately and then joined to the central cylinder I by means of outer vertical joint lines of soldering, or the same can be formed in a single piece from a suitable plastic material, in the latter case the outer vertical joint lines of soldering being omitted.

The length of all incomplete cylinders I0 is smaller than that of the cartridges and slightly greater than that of the central cylinder I, and said cylinders I0 are of the same diameter which may be smaller than or equal to the dliameter of the central cylinder I but larger than the diameter of the cartridges so as to be apt to receive the latter loosely therein.

Each cartridge receiving cylinder I0, whether made separately or forming an integral part of a whole, is open below and its side wall is partly broken away about three quarters of its height from its bottom end, comprising one half of its contour approximately. In other words, start ing from their bottom end, three quarters of each cylinder length forms a semi-cylinder, as indicated by I2 in Fig. 6, the remaining one-fourth portion I3 forming a complete cylinder.

The top portion I4 of each cylinder I0 is closed and provided with a central perforation II to permit the examination of the percussion cap of each cartridge '24, said perforation extending to form a slot II ending near the edge of the wall of the cylindrical portion.

The cartridge receiving cylinders I0 joined to the central cylinder I are so positioned that their slots II are in registration with the slots 2 of the central cylinder.

Within the central cylinder I is mounted a hollow cylinder I5 closed above and open below which smoothly fits into said central cylinder I. Said hollow cylinder I5 is secured to a stem I6 passing therethrough and having its top portion I6 and bottom portion IE of smaller diameter than its central portion.

The central portion of smaller diameter of said stem I6 ends inferiorly in an enlargement I`I adapted to act as a valve to seat on the recess B formed in the bottom I of said central cylinder I, while the lower portion I6" of smaller diameter of stem I6 passes across perforation 9 of said bottom I and terminates in an enlarged end I8 provided with a lower recess i9 adapted to rest on a projection usually provided at the top center of the magazine oi revolvers.

The top portion iii of the stem i5 has its end inserted in the stem 5, which can be introduced further upon the stem I6 being forced upward by pressing the enlarged end I8.

A coil spring 2t surrounds the portion i5 of the stem i6 and the lower portion of stem 5, the lower end of which rests on the inner cylinder i5, and its upper end may be secured exteriorly to the stem 5, or it may rest against the radial arm 2l provided at said stem.

The disc 6 to which the stem 5 is secured by its top end, is positioned within an enlarged eXtension in the shape of a cup 212 formed at the central cylinder l. Normally, said disc is maintained raised by the action of spring 2t which also forces the inner cylinder I5 downward, causing the enlargement I'I of stem i5 to seat on the recess t and thereby obturate the perforation 2.

The radial arms 2! of stem 5 have welded thereto a small ring 33 to which are pivotally connected the pins 23 in a number corresponding to the number of cartridgereceiving outer cylinders id. Said pins pass through the registering slots 2 and ii' of central cylinder i and cartridge receiving cylinders Eil respectively, to protrude in a position into the latter when the disc 5 and consequently the stem 5 are raised by the action of spring 25, as shown in Fig. 3.

In this position, the cartridges 24 inserted in the receiving cylinders i@ with their points downwards, are held in the loader by means of the pins 23 remaining beneath the flange 2t of the tcp end of cartridges 2d.

Upon pressing the disc 6 to the position shown in Fig. 4, thereby causing the stem 5 to descend against the elastic tension of spring- 2% resting on the inner cylinder i5, the pins 23 carried by the ring secured to the radial arms 2i of said stem will be retracted, thereby releasing the cartrides 2d which will fall. In this second position, the ends of the pins 23 will remain within the slots 2 of the central cylinder l, to which end the latters wall is thickened, so as to prevent the pins to fall Vinto the central cylinder, depending from the ring carrying them.

As the pressing of disc 6 is discontinued, the spring 2li will force same to its initial position,

Vthe pins 23 thereby returning to their normal or non-retracted position.

To replace the cartridges 24, the loader is taken upside down and the cartridges are inserted in the receiving cylinders li), with their percussion caps facing the top end of said cylinders lil, and by pressing the disc E so that until the pins 23 are caused to slide downward, the cartridges will penetrate completely, that is, until same rest on the closed end of cylinders Iii, whereafter the pressing of the disc 5 is discontinued, the pins 23 thereby returning to the position in which their ends protrude into said cylinders and hold the cartridges 24% by their flanges.

In said ascending and descending movements of the stern 5, the stem I5 has remained inoperative, by reason of the fact that as the stem E5 is of tubular shape and it encloses the reduced portion iii' of stein it. movement not transmitted from one stem to the other.

The inner cylinder l5 is adapted to contain the oil 2l to be used for lubricating and cooling the revolver chambers. Said oil is enclosed in the chamber formed by the-inner cylinder l5 and the bottom 'i of central cylinder I, and normally said 4 oil cannot flow out through opening 9 as the latter remains obturated by the enlargement or valve Il of stem I6.

The wall of cylinder I5 is provided with an orice 28 in vertical alignment with another orifice 29 formed in the wall of central cylinder i, and both orices are not in horizontal registration whilst the inner cylinder i5 is forced down.- ward by the action of the `spr-ing 23, as shown Figs, 3 and 4.

To lubricate and cool a revolver chambers, the loader is placed in such a position that the projection usually carried by the magazine of a revolver rests in the lower recess I9 of the enlargement i8 of the portion I6 of stem it, and the loader is pressed against the-top center of the revolver magazine, so that the valve il of stem I6 will be raised, thereby opening the perforation 9 of bottom l of the central cylinder i, as shown in Fig. 5. In this position, the orifices 25 and 29 of vinner cylinder 'I5 and central cylinder I will register one another thereby allowing cuter to enter, whereupon the lubricating oil 2i will ow through the perforation 9 and it will spread over the revolver chambers.

Said operation can be effected simultaneously with the reloading of the revolver; in fact, as the points 25 of the cartridges 24 are placed within the revolver magazines chambers, the enlargement i8 will engage the rear face of the revolvers magazine, and by simply pressing the loader against the magazine and actuating the disc '6, the cartridges will be released. Upon withdrawing the loader, the enlargement or valve i? will automatically descend to obturate the perforation 9, in which position the oriiices 28 and 25 will not register one another, and at the same time the disc 6 will be raised to a position as limited by the abutment of arms 2i aga-inst the disc 3.

To fill the loader with lubricating oil, the enlargement IB of portion IB of stem l5 is slightly pressed, so that the valve I'I will open the perforation S through which the 'oil is then injected.

In order to prevent stem i5 and inner cylinder i5 from rotating, thereby bringing the orifices 23 and 29 out of vertical alignment, the upper portion i6 of smaller diameter of the stem I6 has one or two vperipherial plane faces 35. Corresponding plane faces are formed at the inner face of stem 5, so that as said portion Hi is inserted in stem 5, rotation of the stem l5 and inner cylinder i5 is prevented. The described arrangement is illustrated in Fig. 7.

To prevent slipping of the loader from the users hand, the former provided with grooved outer portions, :as vshown in Fig, 1, adjacently to the rsides of ribs I0.

In Fig. 8 is illustrated a modiiied :form of the loader unprov-ided 'with the lubricator-cooler mechanism. In this modified form, all the parts are arranged similarly as in the vloader previously described, except for the lubricating mechanism, and therefore the inner cylinder I5 and the stern i5 are omitted therein. In this form, the `central cylinder I' has a bottom 7 slightly higher than its lower end, so that the extension of said cylinder beneath the bottom 'i' provides a chamber 32 adapted to lodge the central portion of the rear face of the revolvers magazine to facilitate the insertion of the cartridges therein. The stem 5 for actuating the pins, which is not hollow, extends lengthwise the central cylinder I' and lpasses across vthe axial lperforation of bottom 'I'.

A spring 20 surrounds the stem 5' and has its lower end resting on the bottom 1' and its upper end resting against the radial arms 2l to which is secured the ring having the pins pivotally connected thereto, said spring 20 tending to raise the disc 6' to which the top end of stem 5' is secured.

The downward movement of stem 5' is limited by the striking of disc 6 against portions of the upper ends of the cartridge receiving outer cylinders.

It is obvious that changes may be made in the size, oil capacity and number of the outer cylinders, as well as in the construction details of the loader, without Vthereby altering the essential character of the invention, which is such as claimed hereinafter.

What I claim is:

Improvements in revolver loaders of a type adapted for simultaneously reloading and cooling or lubricating the revolvers chambers comprising, a central cylinder, a centrally apertured disc secured to the upper edge of the said central cylinder, a centrally apertured disc secured within the lower end of said cylinder, a recess surrounding the aperture on the inner side of the lower disc, outer semi-cylinders joined to said central cylinder and each cylinder constructed for normally holding a cartridge, upwardly inclined slots extending through the joint of said central cylinder and said outer semi-cylinders, a closed top inner cylinder positioned within said central cylinder thereby forming a chamber and said inner cylinder having a centrally positioned downwardly projecting supporting stem extending through the aperture of said lower disc, an intermediate radial ared portion on said supporting stem adapted to seat in the recess of said lower disc thereby closing the aperture, a centrally positioned stem projecting upwardly from said inner cylinder, a slotted stern positioned above and telescoping over said upwardly positioned stem and extending through the aperture of said upper disc and said slotted stem having a cup shaped head at its upper end and the lower slotted portion slidingly cooperating with the upwardly extending stem of said inner cylinder, arms secured to the lower portion of said slotted stem below said upper disc and extending radially therefrom and positioned to cooperate with said slots extending through the joints of said central cylinder and the outer semi-cylinders, a ring secured to the end of each radial arm, a pin pivotally connected to each ring, and of such length so as to be adapted to support a cartridge in the outer semi-cylinders, a compression spring between the closed top of said inner cylinder and said radial arms biasing them in opposite directions and a cooling or lubricating fluid in said chamber, all constructed and arranged whereby the depressing of said slotted stem head will release cartridges supported by said pins and the depression of inner cylinder supporting stem inwardly will release said fluid to cool or lubricate a cylinder of a revolver.
