Be it'knownthat` citizen of the United States, 'residing l, THoMAs J., Rowan,

at New.,

Castle,"in the countylot Lawrencewand State ot Pennsylvania, have' invented certain new and useful Improvements in 'Protectors for Percussion'Tools,-ot lwhich the following .is

a specification.-

rllhis invention relates to protectors *gto'rv which is meant appli`` percussion" tools, by

ances such as riveting hammers operated either by tri city.

touches or almost touches the surface to be riveted.

Constructed in the tapering two` holders close toy next to the surface to be riveted, the

upper holder contains a plate or isin forward end otk the sleeve, on opposite sides thereof, are, the endk ot the sleeve holders The other transparent material, removably secured in the holder bymcans of a movable fastening, and the lower 4holde'rcarriesa reflecting plate, the purpose of the o and plates being to yafford means tor penings i observe ingboth the upper and lower ,'port'ionsot y and gloves by the operator,

that thel use of thisinvention will the necessity tor the ,wearing ot lt is believed obviate an inconvenient and troublesome essential in present practice, and that it is particularly `use applicable to overhead work.

By the accompanying struction and arrangement ot the parts of this the `drawings invention are' illustrated-` Fig. lrepresents a side view drawings the convarious i ot a rivetinghammerhaving this invention applied thereto. Fig. 2 is a front view of,

Considering vthe drawings, the riveting' hammer A has an enlargementor cylindrical head a, apoint B, and a. tool-b projecting from the point and subjected kto repeated blows, by customarymechanism within the hammer. .Thel tool acts upon the rivet C. The body orjsleeve D of this invention, may bemade of No. 2O galvanized iron, and it has .a re-entorcing band'd at the open end which` is slipped over `and engages the head c oit the hammer A. y Atthe other end ot the 'sleeve is formed a tapering portion E, the moutho'which is re-enforcedby a band e, The tapering end E has two sight the pivoted clip or fastening y'. Theplate iseasily removed and replaced or renewed. The lower sightopening also has side walls Kand and as shown in Fig. 2l guide lugs L and Z are formed to receive the plate kli/l. `This is reflecting' plate, and is held removably in the guides' by the pivoted clamp'm shown.

In explaining the operation ot this invention it will be understood that it is' not confined to the' use of vthe particular tool illus' trated in Fig. 3, and introduced only tor the `purposes ot this description. The rivet C is expanded by the repeated blows in the usual manner, and is freely observable through the transparent plate J, while flying particles struck otfudu'ringthe hammering,- are caught jin the sleeve D, from which they may be readily emptied by tiilrning the hammer downwardly at intervals.A rlhe reflecting' kplate M enables the operator to scrutinize the lower part of the rivet head, and by. suitably inanipulatin,9,l the whole the riveting may be accomplished without danger from the dying particles. In slanting thetool up ,or down to roundv a rivet head, the sleeve l) slips `back `on the hammer, but is easily moved 'forward again, 'The sleeve D lexplained the mode of its operation, what I claim is l. A protector for percussion tools, coiny prising a sleeve body constructed to engage the end of a tool holdei, the said body having its forward end provided with a sight opening having a transparent. closure through which the end of a tool in the tool holder inay be observed.'

y 2. A protector for percussion'tools, coniprising a sleeve body constructed to engage the en'dfof atool holder, the said vbody having'at itsforward end Oppositely disposed 1sight openings, i one of the said openings having` a transparent closure through which the end yofa tool inthe said holder may be observed, and, the .other opening having a reflecting closure whereby the lower portion the end of a tool' holder, the said body having` a tapering, forwardly-extending portion provided with a sight opening having a transparent closure through which the end of a tool inthe toolholder may be observed.

4. A protector for percussion tools, cornprising a sleevefbody constructed to engage the end of a tool holder, the said body hav- ,ing a tapering, forwardly-extending portion provided with opposite'ly disposed sight openings, one of the said openings having a transparent closure through which the end of a tool in the said holder may be observed, and the other opening having a reflecting closure whereby the lower portionoitv the head or a rivet operated upon inay be eX- ainined.

In testimony whereof I aiX my signature.
