SWITCH CLIP.
APPLICATION FILED AUG. 20, 1907.

SWITCH-CLIP.
/ Specification 0! Letters Patent.
Patented March 31, 1908.
- Application filed August 20, 1907. Serial No'. 388,404.
To all whom it may concern:
, Be it known that I, JOHN CLAY, a citizen of the United States, residin in the city of New York, county of New YorE, and 'State of New York, have invented certain new and useful Improvements in Switch-Clips, of which the following is a specification.
My invention in switch clips relates to an attachmentto the blade or arm of an electrical switch, having the form of a clip and is adapted when the blade is thrown in to the switch clip, to engage the jaws thereof, and the object of my invention is to insure increased conductivity between the switch blade and (lllliiOf switches embraced in that class known as nife switches.
It is also the object of my invention to provide 'a more effective means of securing a good electrical contact between the switch lade and cli in the usual type of knife blade switch'than y any of the means hitherto in vogue and previous to my inventionin so far as am at present aware. Other objects of my invention will appear in the drawings hereto'attached when taken in connection with: thedescriptive matter relative thereto, which together form part of this specification, and the distinctive features of novelty are more particularly pointed out inthe claims;
. With reference' to the drawings, Figure 1, is a side elevational view of my mvention as.
' attached to a switch arm. Fig. 2, is a verti- ,cal sectional view thereof takemon the line 22 of Fig. 1. Fig. 3, is a perspective view of my improved clip somewhat enlarged.
In the different figures, similar characters of reference are em loyed to designate like parts throughout, w erein,
A illustrates the usu 1 type of switch blade or arm as employed in the majority of sinale and double pole electrical switches and the usual type of spring switch clip.
In racticeI have found that'during con-- tinua use, the en agement and disen agement of the blade "with and from the c ip B has the tendency of s reading the jaws a, b, so that the de ree oi contact between the said jaws and t e bladeA diminishes, owing to the wear of the co-acting parts and also tov the lossof resiliency of the aws a, b, result- I arm A which is constructed in the manner of a clamp which forces the jaws a, b on to the blade A when the latter is: engagedin its clip/I13.
y improved switch clip as illustrated in connection with the .switch arm A in its simplest form, consists of preferably a blank of sheet metal, folded in a manner so as to rovide two erforated lugs C, D through w ich the switcii arm A is passed, and two lateral clip lugs or jaws E and F adapted to straddle the blade A and the jaws a, b of the. switchcli B. The'lugs E and D are adaptedto. fit tightly on the switch arm A by providing the perforations 'c, and d in said lugs of su'flicient dimensions to enga e said arm by its edges and sides, and in a dition to the securing of may improved clip to the arm A, I provide an a ditio'nal erforation e to engage the head of a screw 8, which is employed as the customary fastening between the blades and handles of switches of this character.
It will be observed by'the foregoing descri tion when taken together with the illustrations that when the switch blade A is thrown into the clip B, the jaws E and F of my improved switch clip or clamp oval? and engage the jaws a, b of the switch cli and thus prevent the latter from spree ingthereby o viating the depreciation of congaot bgtween the switch blade A and the clip an I Having fully described my invention, I claim as new and desire to secure by Letters Patent of the U. S.
1. In an electrical switch, a clamp carried by the switch arm and secured thereto, consisting of a pair of perforated lugs and a pair of contact clips integrally formed with said clamp and the said clips, bein adapted to engage a switch clip upon the c osing of the I switch.
2. An attachment for electrical switches comprising a supplemental clip provided with jawsconnected b intermediately disposed integrally forme erforated lugs, said clip beingcarried by and secured to a switch blade of the said switch and adapted to engage the co-acting switch clip and force the same into contact with the said blade upon the closing of the switch.
3. In an electrical switch an attachment for the switch blade, consisting of a clip provided with lateral jaws and erforated securin lugs integrally formed t erewith, said latera lugs adapted upon the closing of the switch, to thrust the switch blade of said switch.
4. In an electrical switch, a clamp carried by the switch blade, consisting of a blank formed about the switch blade and provided with a pair of securing lugs and a air of lateral clips, said clamp bein attac ed to the said blade by the securing ugs and a perforation in one of the said securmg lugs adapted to receive the neck of a screw, said switch clamp being adapted 'to engage the switch clip u on the closing of the switch.
5. Iii an electrical switch, provided with a switch arm and a switch clip co-acting thereclip against the with, the combination with the said arm and said switch clip, of a clamp provided with a perforated securing lug secured to the said switch blade and lateral contact lugs ada ted to contact with the switch clip upon t e closing of the switch.
6. An attachment for electrical switches, consisting of a clamp, formed of a blank of thereto, consisting of a pair of perforated lugs, and a air of contact lugs substantially at ri ht angles thereto and a common fastening or the switch blade handle of the said switch and clam said clamp adapted to engage the switch 0 amp upon the closing of the swltch, substantially as described.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses. A
