DELBERT E. BARTON, OF RACINE, WISCONSIN.
SNAP-HOOK.
Specification of Letters Patent.
Patented April 16, 1907.
Application filed March 16,1906. Serial No. 306,365.
To all whom it may concern.-
Be it known that I, DELBERT E. BARTON, residing in Racine, in the county of Racine and State of Wisconsin, have invented new and useful Improvements in Snap-Hooks, of which the following is a description, referenoe being had to the accompanying drawings, which are a part of this specification.
This invention relates to new and useful improvements in snap-hooks, and has for its object to provide a snap-hook of novel construction whereby the compression-spring may be placed in position after the other parts are properly connected together and have been finished, so that the spring is not subjected to injurious influences consequent to the finishing of the other parts.
Another object of this invention is to so construct the parts that a broken or exhausted spring may be readily removed and replaced by a fresh one.
Another object of this invention is to provide for keeping the parts free from dirt and moisture.
Another object of this invention is to generally improve upon the details of construction.
With the above and other objects in view the invention consists in the snap-hook, its.
parts and combinations of parts, as herein claimed, and all equivalents.
Referring to the accompanying drawings, in which like characters of reference indicate the same parts in the several views, Figure 1 is a plan view of a snap-hook constructed in accordance with this invention. Fig. 2 is a side elevation thereof with parts sectioned. Fig. 3 is a transverse sectional view taken on Fig. 4 is a plan view of a fragment of the hook member before the tongue is placed in position thereon. Fig. 5 is a side elevation thereof with the loop in section. Fig. 6 is an inverted plan view of the tongue member before it is connected with the hook member; and Fig. 7 is a transverse sectional view of the snap hook, showing the position of the compression-spring while it is being forced into the throat formed between the hook and tongue members.
In the drawings, 10 represents a hook member which is broadened at its upper end or head where it joins with a loop or connecting means 11, which may be of any desired shape or construction. At the broadened upper end of the hook member there is a pair socket 16, with an opening 17 at its bottom passing entirely through the head of the hook member. Near one side of the chan nel formed between the guide-walls 15'is a gradual incline which ends abruptly at the edge of the socket 16, so as to form a cam or stop lug 18 with the shape in cross-section as shown in Fig. 3.
The tongue vmember 14 is similarly provided with approximately parallel side walls 19, forming a channel between them which ends in a rounded spring-seat 20. In this instance the spring-seat is not depressed below the bottom of the channel and is bounded in front only by the cam or stop lug 21. which is formed similar to stop-lug 18 of the hook member. The spring-seat also contains an opening 22, which stands directly opposite the opening 17, as clearly shown in Fig. 2. The cam-lug 21 on the tongue member is so located that when this member is placed in position in the trunnionbearings the cam-lug will be on the opposite side to cam-lug 18 of the hook member, as shown in Figs. 3 and 7, and their inclined side surfaces 00 will be approximately parallel. The channels of the hook and tongue members form a throat between them with guide-flanges' on either side, down which throat a coil-spring 23 may be forced when compressed to its full extent, so that its convolutions are in engagement with each other. The cam- lugs 18 and 21 serve to tilt the compressed spring to one side during its passage and afford just sufficient space between them for the spring to pass, as shown in Fig. 7. When the spring is forced beyond the rear ends of the cam-lugs and into the spring-space formed between socket 16 and the spring-seat 20, it expands to a natural condition only slightly under compression and assumes avertical position, as shown in Fig. 3.
The coil-spring 23 when in position behind the cam- lugs 18 and 21 is incapable of being accidentally displaced, as the abrupt ends of these stop-lugs effectively bar its passage outwardly. This is true even when the spring has become weak and shortened by long use, though by means of a pointed tool inserted through the throat between the hook and tongue members such defective springs and springs which have become broken may be removed and new springs may be inserted, just as with the original spring.
Snap-hooks as previously constructed have not been designed to receive their coil compression-springs after the assemblement of the other parts, and consequently these springs have to be inserted while the parts are being assembled and are therefore subjected to the tinning or other finishing process along with the remainder of the snap-hook. The temperature influences which the springs undergo during the tinning process imp air their temper and render them short-lived and of inferior quality, and the tinning process frequently serves to solder them to adjacent parts, so as to have the effect of shortening them by depriving them of action throughout their full length. The snap-hook constructed in accordance with the present invention does not receive its spring until after the tinning or japanning process is completed, and
, consequently such defects are avoided.
Theopenings 1.7 and 22 allow of all dirt and mud being forced out of the spring-space when they happen to gather there and, furthermore, prevent the collection of water in said space to freeze and impair the efficiency of the device.
hat I claim as my invention is 1.
