G. W. HARPER TERMINAL AND CLAMP THEREFOR Filed Aug. 13, 1945 INVENTOR.
A TOR/YEYS.
Patented Jul 27, 1948 UNITED STATES PATENT OFFICE TERMINAL AND CLAMP THEREFOR Glen Wood Harper, Manhattan, Kans. Application August 13, 1945, Serial No. 610,620
3 Claims. 1
This invention relates to a terminal and clamp therefor, and more particularly to a clamp adapted for use as a battery terminal holder.
Heretofore it has been the custom to place the terminal on the battery post and clamp it in place by the use of a bolt and nut, the bolt being inserted through openings in the outer ends of the battery terminal. It is well known that with devices of this character the terminal bolt and nut will corrode, making it diiiicult to remove the terminal from the post.
The principal objects of the present invention are to provide a clamp which may be easily and quickly applied to a cable terminal to hold the terminal on the post of a battery; to provide a device requiring no tools for assembling it on the terminal; to provide a device which insures positive contact between the terminal and post; and to provide a. device which is simple, economical to manufacture, and efiicient in operation.
In accomplishing these and other objects of I the invention, I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:
Fig. 1 is a perspective view of my invention showing the clamp attached to a terminal engaging a post of a battery or the like.
Fig. 2 is a plan view of the device showing the clamp in locking position.
Fig, 3 is a View similar to Fig. 2 but showing the clamp at the beginning of the clamping operation.
Fig. 4 is a perspective view of my clamp shown in disassembled relation with a battery cable terminal.
Referring more in detail to the drawings:
l designates a storage battery or the like having a post 2 to which a terminal 3 of a cable 4 may be engaged as will presently appear.
The clampin device embodying the features of my invention consists of a body member 5 and a locking bar 6. The body and locking bar are preferably made of spring steel having considerable resiliency, but at the same time being strong enough to exert a clamping force as will later be shown.
The body 5 has an elongated portion 5' with one end curved to form a substantially semicylindrical portion 1 to provide spring to the clamping member. The opposite end of the body is rounded as at 8 to form an end 9 and is curved slightly inwardly as indicated at 10, thence slightly outwardly and then inwardly, the extreme outer end being turned slightly inwardly to form a recess of the end 9 as indicated at l5 (Fig. 2), when the locking bar is engaged with the body in locking position on a battery terminal. The opposite end of the locking bar is turned transversely forming a handle portion IE on the locking bar. It will be noted that the body [2 of the locking bar is recessed slightly as indicated at ll-(Fig. 2), for engaging with the battery terminal when the locking bar and body of the clamp are in locking relation to the terminal.
The battery cable terminal is attached to the cable in the usual manner and comprises a shank l8 and an enlarged end portion comprising a rounded head portion I9. The head is provided with an opening 20 adapted to receive the post 2 of the battery and the head is provided with a longitudinal slot 2| so that there will be a resiliency in the head so that the terminal may be easily placed over the post. It will be noted that the outer portion of the slot 2| is slightly larger than the inner portion as indicated at 22 (Fig, 3) The head has outwardly extending portions 23 and 24 provided with indentations or recessed portions 25 and 26 for a purpose later described.
Operation of a device constructed as described is as follows:
The head ill of the battery cable terminal is spread so that the bore opening 20 will fit over and engage the post 2 of the battery. The inner edge of the substantially semi-cylindrical end portion I of the body 5 of the clamp is engaged in the recess 25 of the terminal as indicated at 21 (Fig. 3). The extreme outer edge of the hook portion iii of the clamping bar [2 is engaged with the recess II in the end 9 of the body member with the rounded portion of the hook l3 engaged in the recessed portion 26 of the terminal as indicated at 28 (Fig. 3). Inward pressure is applied to the handle I6 which will exert pressure on the head of the battery terminal as indicated at 21 and 28 (Fig, 3), and continued inward pressure will cause the locking bar to assume the position shown in Fig. 2, drawing the head together so that the terminal will be held firmly on the battery post. The recessed portion I! of the locking bar will engage the rounded portion of the head and the hook portion of the bar will have its slightly rounded outer portion engaging in the recess l l of the body of the clamp, thus rigidly retaining the locking bar and body in clamping relation on the terminal.
The inwardly turned portion of the extreme outer end of the end 9 of the body member will provide the recess ll so that the extreme outer end of the hook portion I 3 will engage therein and the spring-like tension of the body member will prevent the locking bar from being disengaged. However, regardless of any corrosion of the terminal, the parts may be disengaged by outward pressure on the handle I6 and the head sprung apart for disengaging from the post for disassembling the terminal from the post.
It will be obvious from the foregoing that I have provided an improved terminal and clamp therefor which may be quickly and easily asseme bled and disassembled from a battery post as above set forth.
What I claim and desire to secure by Letters Patent is:
1. In a device of the character described comprising, a cable terminal, said terminal having a head provided with an opening adapted to engage a post of a battery, said head having a longitudinal slot located centrally of said head terminating at said opening and providing outwardly extending arms having recessed portions on the outer surface of said head, a clamp for anchoring said terminal to the battery post, said clamp including a body of spring metal having a substantially semi-cylindrical portion adapted to engage in the recess on one side of said head and its opposite end turned transversely inwardly and having a. recessed portion on its inner face, and an arm having a hook on one end engaging in said recess on said transversely turned portion and the recess in said terminal for exerting inward pressure on said terminal.
2. In a device of the character described comprising, a cable terminal, said terminal having a head provided with an opening adapted to engage a post of a battery, said head having a longitudinal slot located centrally of said head and extending inwardly to a point beyond said opening and providing outwardly extending arms having recessed portions on the outer surface of said head, a clamp for anchoring said terminal to the battery post, said clamp including a body of spring metal having a substantially semi-cylindrical portion adapted to engage in the recess on one side of said head and its opposite end turned transversely inwardly and having a recessed portion on its inner face, and. an arm having a hook on one end engaging in said transversely turned portion and the recess in said terminal for exerting inward pressure on said terminal.
3. In a device of the character described comprising, a cable terminal, said terminal having a head provided with an opening adapted to engage a post of a battery, said head having a longitudinal slot located centrally of said head and providing outwardly extending arms having recessed portions on the outer surface of said head, a clamp for anchoring said terminal to the battery post, said clamp including a body of spring metal having a substantially semi-cylindrical portion adapted to ngage in the recesson one side of said head and its opposite end turned transversely inwardly and having a recessed portion on its inner face, and an arm having a hook on one end engaging in said recess on said transversely turned portion and the recess in said terminal for exerting inward pressure on said terminal, said arm having a recess adjacent the hook to conform to the head of said terminal.
