BATTERY JUMPER Filed Nov 20, 1929 lnvenTor. Harry Se be by MkM Patented Apr. 19, 1932 UNITED STATES PATENT OFFICE nanny steam, or BOSTON, massacnusn'rrs, ASSIGNOR T MAX CORINBLATT, or Bos'roN; MASSACHUSETTS BATTERY JUMPER Application filed November 20, 1929. Serial No. 408,463.
This invention relates to devices known as battery jumpers. This term is used in the trade to indicate a connection for connecting the terminals of storage batteries while they are being charged. These socalled jumpers comprise a length of wire having at each end a terminal adapted to be connected to the battery terminal.
The wire terminal is usually in the form of a shar spike or point which can be driven into the attery terminal and the connectlng of the jumper to the battery involves driving the jumper terminals into the battery terminals.
There is a tendency for the jumper terminals to become corroded when in use and if the terminal is of the spike variety the corrosion will soon bring it into a condition when it is not suitable for use because of the difiiculty of getting a good clean contact with the battery terminal. Whenever any jumper terminal thus becomes corroded the entire jumper or connector is usually discarded and replaced by a new one.
It is one of the objects of my invention to provide an improved terminal for a battery jumper which has a removable contact member so that if the contact portion of the jumper becomes corroded it can be readily disconnected from the connector and replaced by a fresh contact member. The jumper or connector can thus be put back into its original state at a minimum expense thus avoiding the necessity of throwing away the entire connector just because one terminal has become somewhat corroded.
In order to give an understanding of the invention I have illustrated in the drawings some selected embodiments thereof which will now be described after which the novel features will be pointed out in the appended claims.
Fig. 1 is a perspective diagrammatic view illustrating some storage batteries connected as they would be while being charged and also illustrating how my inventlon is used;
Fig. 2 is an enlarged sectional view through one of the terminal members of the connector or jumper showing it applied to a battery post, the removable contact member being shown on substantially the section 2-2,
Fig 6;
ig. 3 is a sectional view of the terminal member removed from the post and illustrating the removable contact member on the section 33, Fig. 6;
Fig. 4 is a sectional view showing a differentembodiment of the invention;
Fig. 5 is a view of the cap member illustrated in Figs. 2 and 3;
Fig. 6 is a perspective view of the removable contact member shown in Figs. 2 and 3;
Fig. 7 is a perspective view of the cap member shown in Fig. 4.
As stated above the device relates to a con-- nector or so-calle'd jumper designed to con-- nect the terminals of two storage batteries 1 as shown in Fig. 1 while said batteries are being charged.
This jumper comprises a length of connecting wire 3 which has a suitable terminal at each end adapted to be connected to the posts 4 of the batteries 1. In my improvement each terminal member comprises a cap or body portion which is permanently connected to the wire 3 and a contact member removably sustained by the cap member and adapted to engage and make the necessary electrical contact with the battery post 4. In the device shown in Figs. 2 and 3 the cap member of each jumper terminal is indicated at 5 and it is preferably stamped into shape from sheet material. The wire 3 is permanently connected to the cap member 5 in some approved way.
The removable or replaceable contact member of the terminal is indicated at 6. This may also conveniently be made from sheet metal which is stamped into the desired shape and it has a general cap formation adapted to fit over the battery post 4. This member 6 is provided with a plurality of arms 7 arranged to engage the side walls of the post 4, each arm having struck up therefrom a spur 8 which is so constructed that when-the terminal member is placed over the battery post 4the-spurs 8 will have a cutting or scraping action on the posts providing a clean contact and a correspondingly good electrical connection.
As stated above the member 6 is removably held in the retaining ca so that it may be readily removed there rom. Hence if the portions of the contact member 6 which have contact with the posts 4 of the 'battery be! come corroded or otherwise unfit for use the contact member 6 can be readily removed from the cap 5 and replaced by a fresh contact member.
One simple way of making the ca 5 and the contact member 6 so that one can e readily separated from the other is to make the cap- 5 with the edge 9 bent inwardly slightly and to make the contact member 6 with the resilient retaining arms which are of such shape and length that when the contact member 6 is inserted into the cap the ends of the retaining arms 10.will spring outwardly behind "the inturned rim or edge 9 of the cap member 5 thus yieldingly holding the con tact member in place.
The contacting arms 7 of the contact member 6 are slightly curved with outwardly-directed or flared lower ends so that the contact member can be readily placed on a battery .post 4. There is sufiicient resiliency in the arms 'Z so that the pressure which the arms supply to the sides of the post cause the spurs 8 to have a scraping action on the posts thereby providing a clean and efiicient electrical contact.
The contact member 6 can be readily removed from the cap member 5 bysimply either applying suiiicient pulling strain to the legs? or by bending, by means of a suitable tool, one of the retaining arms 10 inwardly sufiiciently to disengage it from the rim 9 and then withdrawing the member 6.
In Figs. 4 and 7 Ihave shown a slightly differentembodiment'of the invention wherein the cap or body member 13 of the terminal and to which the wire 3 is secured is provided with the retaining groove 14 and has its side walls slit as shown at 15 to permit said walls to be expanded radially.
The contact member 16 is provided with the contactin arms 17 each of which has a spur 18 struc up therefrom and said contact member is also provided with a retaining rib 19 adapted to be engaged in the retaming groove 14.
The cap member or holder and the contact member are assembled by forcin the contact member into the cap member, t e resiliency of the side wall of the cap member or holder due to the slits 15 permitting it to expand sufiiciently to allow the rib 19 of the contact member to be carried into engagement with the groove 14. The resiliency of the side walls of thejcap member also permit the contact member to be readily removed when it becomes necessary to discard it and to replace it by a fresh contact member. 7
In both embodiments of the invention the connector or jumper is provided with terminals each of whichcomprises a holder member or cap member that forms a permanent part of the device and a contact member removably carried by the body or cap member and having means to engage and form an electrical contact with the battery .post 4.
A battery jumper or connector embodying, my invention can be used for a long time by simply replacing the contact members as oocasion requires and this may be done at a mmlmum expense.
I claim:
1. A connector for storage batteries comprising a connector wire having a terminal at each end, each terminal comprising a holder member permanently connected to the wire and a contact member removably carried by the holder member, the contact member having resilient contacting arms adapted to engage the side walls of the battery post, each arm having an upwardly and inwardly inclined spur struck up therefrom shaped to scrape the post when the contact member is applied thereto.
2. A connector for storage batteries c0mprising a connector Wire having a terminal at each end, each terminal comprising a cupshaped body portion. permanently connected to the wire and a contact member situated within the body member and adapted to fit over the battery post, said contact member having resilient contacting arms which project beyond the open end of the body member and have integral therewith upwardly and inwardly directed spurs.
In testimony whereof, I have signed my name to this specification.
HARRY SEBELL.
