2 I SPECIFICATION forming part of Letters Patent No..534,211, dated' February 12, 1895. V

' Application filed April 20, 1892- Serial 110.42%),868. (No model-l T all whom it may concern.- i Be it known that I, CHARLES H. ENGLISH, a ,iOilJi ZGII of the United States, residing at VVashyington, in the District of Columbia, have infvented certain new and useful Improvements jin Finger-Protectors and I do declare the fol- -jlowing to be a full, clear, and exact description f the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates tofinger protectors iand it is an-improvement on a similar invenition shown in an application filed by me February 18, 1892, Serial No. 422,828, patented April 10, 1894, No. 518,027.

The object of my invention, is as in my other application to so construct a finger tip :that the impact of the blow incident to strik- :ing the key of a typewriter, 850., will not be i received on the end of the finger of the operator but will be received directly on the wall of the tip or guard while the finger end rests lightly upon a perforated lender in the end of the tip. I also providethis improved tip with the alternately broken corrugations and the perforations between such corrugations all of which together with their advantages are fully set out in my former application. It will of course be understood, that I may use continu- 1 ous corrugations without departing from the J spirit of myinvention and if found desirable {I may entirely dispense with such corrugations but I prefer to use them.

In the drawings: Figure 1 isalongitudinal 3 vertical section through my improved tip. Fig. 2 is a bottom view of the same. A represents the tip composed of any suit- I able material, but preferably of soft rubber. This tip is made in difierent sizes on the order of gloves so that a person wearing a No. 5 1 glove can be supplied with a tip of the exact 1 size as well a person wearing a larger one. a are the corrugations illustrated as broken and j lbreaking joints with each other, so to speak, ,although they are entirely independent of Reach other. The finger'is only compressed .lwherever the corrugations touch it and even then such compression is very slight as it has been found that the adhesion between'the rubber and the flesh is sufiicient to hold a Qcomparatively loose tip or guard on the fin- Qger end.

The lower end of the tip or guard is. concaved on the under side as at 1) thereby forming a buffer for the end of the finger. This bufier is perforated as at 6 through which air enters and circulates between the corruga- 6o tions and 'around the finger. b indicates solid rubber between the sides of this buffer and, the walls ofthe tip or guard thereby strengthening the buffer. In practice the fingerend will rest lightly upon the louder be- 6 tween the perforations b The bufier consists substantially of one half of a hollow ball inserted and cemented or otherwise secured between the walls of the tip or guard; or the buffer may consist of a hollow cone shaped body. Around this bufier on the bottom is a rim Z forming the extreme end of thetip It will be supposed that the tip has been put on the finger end and a blow struck. The 7 5 impact of the blow will be received on the rim Z and conveyed to the walls of the tip or guard and it will be found that the finger end is still resting lightly on the top of the buffer. In the event of an extremely hard blow so it will be found that the top of the bufier will be depressed to a certain degree by the end of the finger thereby obviating any damage or blunting of the finger. .7 p

In the manufacture of this device I may 8 mold the tip or guard and the buffer separately and cement the buffer in the lower end of the guard in a well known manner or I may if preferred mold the entire device integrally,

either way being practical as every one versed in the manufacture of rubber goods knows.

What I claim, and desire to secure by Let ters Patent, is-

1. A tip having a butter on its lower end and provided with a rim to receive the impact of the blow.

2. A tip provided with a concaved perforated buffer for the purpose described.

3. A tip provided with a perforated buffer and a rim, said rim forming the extreme end of said tip and adapted to receive the impact of a blow for the purpose described. 7

In testimony whereof I affix my signature in presence of two witnesses.

EDWIN S. OLARKsoN' M. DORIAN.
