"RIVM-HOLDER.

v Application ined December 24, 1910. seriai No. 599,092.

financien, a citizen of the United`States, re-

.the saine is to produce an iinin-oved rivet siding at (irrants Pass, in the. county of.

Josephine and' State of Oregon, have inventeda nw and useful Rivet-I-Iolder,'of which the follou-'ing is a specification.

'lhis linvention 4relatesto riveting niaehines, andinore espccially'to that. type thereofl adaptedtor use in tubular articles sueh as pipesI or boilers;-and the object: 0f

holder or anvil for insertion into/the pipe or boiler to hold the head of the rivetwhile the workniai'i on the exterioris pounding on the shank thereof.

The invention consists in a rivet holder constructed so as to yieldingly support its anvil, and with provision whereby the exitire device may beredueed in length for insertion into or removal from the boiler,

rall' as. herein more fully-described and claimed and as shown in the drawings f tion through the in'iplei'i'ient itself.

wherein-- Figure l is a section of a boiler and an elevation with my improved implement Fig. 2 is a vertical central sec- Fig. 3 is a horizontal section on the line 3 3 of ["igjz.V

This rivet. holder comprises primarily an therein.

a.ii\'il, a, base aiul yielding` support for the anvil,'and a lever n'iechanism whereby the' support. eau be compressed so that the length ot' the entire implement may be reduced.

l/he anvil itsell' comprises a solid member l having' a socket 2 in its upper end for the reception ot the head of the rivet 3 winch f is here shown as passing through theshell ol irhoiler ll, and this member telescopes into a tubular member .'i and is adjustable therein by means of a pin or bolt (l passing through the tubular member and through lone of a series of holes 7 in the solid meniber. ly this or equivalent means-of adjustmentol" the length, the implement may be adapted to work ol dilferent size. The

tubular member has at about its nud-length an aniiularrigid collar and through this member, preferably just; above the collar, ex-

tends a 'pin or'pivot bolt 9.4`

'.llie base comprises a loot l1 from which risesqa solid steinl l2 lit.ting telescopieallyV and slidalil-y u'itliiii the lower end olftlie tubular member 5, and around these parts is 'coiled 1n-.expansive "spring 13 resting ,at Iits lower endupon the foot and pressin upward at; its upper end berieaththe col ar 8; It follows that with .theuse of such yieldingsi'ipport, the anvil would be held about specification @fietsers iatnp May 9', 1911 as seen in Fig. 2 and the weight -ofanyblowsl upon thel rivet-will be communicated through the spring 13 to the base and resisted by` the foot of the latter which presses upon the lower side'of the work 4, and therefore the spring must be ot sutilcient force to resist the impact'l of the strongest blowswhich will be necessary to upset the. rivet. In order to insert this iinpleii'ientvinto thework 4, it is ob vious'tlia,t the rather powerful spring` 13 must-be coin'- ressed manuali andvin order todothisv I make use ofthe following device.

y'l`hehgver n'ieehanisiii comprises :i lever 2l forked at itsforward"endif as atflso as to pass astride the tubular member 5 and having the arn'is ofthe fork li'i'iounted"pivotally on the'bolt 9, and .their loiward-extreinitics l Y 'arcpivoted as at 23 to the upper ends of links whose lower ends are pivotedat 25 to the baseat: any suitable point but'l prefer# sof ably to the opposite sides of'itstoot; 1l. las Y shown. Itis obvious the depression of thel outer end of the lever will cause .the bolt'y El to descend andthe. collar S to compressthe spring '122. and as this shortens the entire length of tlui'iiiipleineiil 'l'lie latterrniay then be inserted into the boiler in order. to llit'I invention,

teleseopically surrounding the solid mein-jl l ber and havii'ig :in annula'il eollar, ainlineaiis `for adjustalily connecting these nieni'bersto each other; a liase consisting olla foot; and a Ystein fitting l'eleseopieallly und 'lmisely within saidptiibular member. and u spring surrounding' tliese parts betweeiiftlie vlootf 9er-errv Ai a lever hevinga-vforkedfront end stra'tldling.
