JOHN FIELDING, OF PROVIDENCE, RHODE ISLAND. ASS IGNOR OF ONE-HALF TO JOSEPH P. WHITAKER, OF APPONAUGH, RHODE ISLAND.
SAFETY-CATCH.
Application filed September 30, 1920. Serial No. 413,835.
To all whom it may concern: 7
Be it known that I, JOHN Frnnomo, a citizen of the United States, residing at Providence, in the county of Providence and Eltate of Rhode Island, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.
This invention relates to safety catches for pins, brooches, and the like, and is an improvement on my prior application, Serial Number 375,361, filed April 20, 1920; and the object of my present invention is to provide an improved construction of keeper which comprises a pair of spaced-apart side ears having a guard member rotatably mounted between them, said ears being pro vided with means for preventing their free edges from spreading, whichconstruction is of great advantage particularly where the device is made of thin stock such as is the case when the same is constructed of pre cious metals such as gold, silver, or platinum.
A further object of this invention is to also provide means for preventing the ring shaped guard member, which is rotatably mounted between the keeper ears, from spreading due to the effect of excessive strains upon it.
The nature and advantage of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.
In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a side elevation of my im proved safety catch mounted to receive the pointed end of an ordinary pin-stem.
Fig. 2 shows the keeper member in e); tended position as cut from sheet stock.
Fig. 3 is sectional edge view showing the ears of the keeper as slightly spread apart and the guard member as mounted upon the trunnion between them.
Fig. 4 is a front elevation ShOWIIIg the free edges of the keeper ears as locked together against spreading, by cross bars.
Fig. 5 is a top edge view of the catch member. a
Fig. 6 is a side elevation with one of the side earsremoved showing the guard member in open position.
Fig. 7 is the same as Fig. 6 but showing the guard member in closed position.
Fig. 8 is a perspective view showing a detail of the ring-shaped guard member with an entering marginal slot.
Fig. 9 is a top edge view illustrating a modified construction of the catch in which a separate and independent locking bar is provided, means also being provided on each side ear for embracing and locking the op posite ends of this bar. A
Fig.10 is a perspective view illustrating the independent locking bar removed.
With reference to the drawings, 10 designates theusual pin-stem as being mounted in a joint member 11 attached to the body portion 12 of the pin, and also showing my improved safety-catch member 13 as connected to the opposite end of the pin body to re ceive the pointed end of the pin'stem.
This catch comprises a keeper member which is preferably first blanked out of sheet stock into the sha V e best illustrated in Fig. 2, having a pair 0 side cars 14 and 15 connected together by a base portion 16.. Each of these cars is provided with a nai ginal slot 17 which extends inwardly from the edge to the center portion thereof and the Gfi-1 1t is shown as being provided with a trunnion 18 which extends laterally from i the inner face thereof. i The inner surface of the opposite car 15 is provided with a counter-borefor recess 19 into which the free end of the trunnion sets when the ears are in operative position. The car 14 is also shown as being provided with a plurality of integral bars or arms 20,
. each having an enlargement or head 21 on their free ends, and theopposite car 15 shown asbeing provided with correspondingly bendable lugs 22 for embracing the head portion of each of these arms 20, to
Specification of Letters Patent. Patented Mar, 29, 1921,
6 24, while the other side of the slot 24 is suplook the ears against spreading when bent up into operative position.
In order to close the marginal slots 17 in these ears to securely lock the pointed end'of the pin-stem when inserted therein, 1 have provided a guard member 23 which is preferably made in substantially ring shape having a marginal slot or opening 24 through it into its center 25, which slot or opening is adapted to register with the slots 17 in the side ears of the keeper, as illus: trated in Fig. 6, when it is desired to admit the pin-stem therein. This guard member is provided with an operating handle'26 and is mounted-to rotate upon the trunnion 18 3 between the side ears.
In some instances, particularly where the keeper is made of any of the'precious metals, such as gold, silver or platinum, it is found very desirable to be able to form both the keeper and the guard member very small and of thin stock and when so con stru'cted it is essential that the whole should be made in such a way that it will still be strong and durable to. resist the heavy strains to which it issometimes subjected, without distortion.
In order to accomplish this result in a simple and effective way I first provide means whereby the side ears when positioned with the guard member between them, willbe prevented from spreading; and one means of accomplishing this is to provide one or more locking bars 20 which will be adapted to extend from the mar in of one ear to the margin of the opposite ear-and be connected to both of these ears to prevent them from spreading under heavy strains Which are often brought upon them. To accomplish this, these arms or bars 20 may be integral at one end with one of the ears,
and its free end may be engaged bye pair of bendable lugs 22 to 'lock this free end securely in position, or in some other cases the bar27, such as illustrated in Fig. 10.
"may be formed separate and independent of theside ears and have both its opposite ends connected to the two opposite ears, as best illustrated in Fig. 9, but I do not wish to berestricted to any particular means of connecting the side ears, as any suitable means may be employed for preventing these ears from spreading.
It is also found in practice necessary in some'instances, to provide means for preventing the guard member 23 from spreading and this I have accomplishedby providing a shoulder 28 in one of the side ears of the keeper against which the outer face ofthe guard rests, on one side of its slot portedby-either one or both of the front cross bars 20, see Figs. 6 and 7. v
The device is extremely simple and practical in construction and by the use of my improved means for preventing the parts from spreading they may be made very thin and light and still be strong and durable.
The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
I claim:
1. A safety catch comprising a keeper, having a pair of spaced-apart side ears connected together at their base portions and adapted to be secured in position against rotation, a guard member rotatably mounted between said ears, and means for preventing the free edges of said fixed ears from spreading.
2. A safety catch comprising a keeper having a pair of spaced-apart side ears connected together at their base portions and adapted to be secured in position against rotation, and a cross-bar connecting the free edges of said fixed ears to prevent them from spreading.
nected together at their base portions. and
a cross-bar connecting the free edges of said ears to prevent them from spreading, and means for locking said bar to said ears.
4:, A safety catch comprising a keeper having a pair of spaced-apart side ears connected together at their base portions, a cross-bar. connecting the free edges of said ears to prevent them from spreading, and bendable lugs on the ears engaging the free end of said bar to lock it in position.
5. A safety catch comprising a keeper having a pair of spaced-apart side ears connected together at their base portions, and a bendable cross-bar integral at one end with one of said ears and secured at its opposite end to the opposite ears to prevent them from spreading.
6. A safety catch comprising a keeper having a pair of spaced-apart side ears connected together at their base and provided with marginal slots, a ring-shaped guard .member rotatably mounted between said ears and also provided with a marginal slot.
carried by one of said ears providing a peripheral support for said guard on opposite sides of its center to prevent said guard from spreading.
8. A safety catch comprisin a keeper havin a pair of spaced-apart si e ears connecte at their base and providedwith marginal slots, a ring-shaped guard member rotatably mounted between said ears and also provided with a marginal slot, and a shoull0 der formed on the inner face of one of said ears to provide a peripheral support for said guard member.
