To all.. whfimitpmg/y coin-cenni.- Be it knownl that We, WILLIAM H. RAY yand EDWARD'CBAIG, citizens of the United States,

residing' at St.. Joseph, countyj of Berrien,

State of Michigan, have inventeda certain new andi-useful Improvement inA Staplin Machines, l'of which the followin isa speciigication, reference being had to tl e accompan ving drawings, forming part thereof.

Our invention relates to stapling-machines in general, but particularly to machinesi for ation of staplingfruit. boxes or.b askets; to

sta ling fruitboxes and baskets, and es e-' vcia ly to machines capable of driving a p u? rality of staples.`

f Objects ofour invention areto provide a '.simple, an easily-0 erated, and a'highly-eflicient stapling-mac ine.;` to simplify the .opere provide Aimproved means'ffor forming and driving the' staples;` to provide improvedl means for feeding the ,-wire; to insure 'accui racyand certaintyin `the formingand drivi' ing of the staples; to' improve the arrangement and action*r of 'the loop-bars", to providel .2'5

an improved rotary formfo'r holding the box or basket; to provide means for automatic- .allylockingthe form against rotation, and to provide certain details and lfeatures ,of im'- provement tending to render a machine 'of this character serviceable and thoroughly re- To the attainment 'of the foregoing'and other useful ends our'invention consists in mattershereinafter. set forth. and claimed.

lAsillustrated, -it will be seen that the two pawls c3 and 'c4 are carried or pivotally mounted on. the vtwo parallel upper-reciprocatin 'portions Z of the reciprocating head C. he pawl c3 is pivotally mounted at -e, while the pawl c4 is pivotally mounted at z. With this arrangement the lower ends of the two pawls, together with the feed-rolls, are conveniently embraced between the stationlary parallel portions Z Z', it being observed that the upper of said feed-rolls is f eerably mounted u on a removable bolt 2. Inthis i way only t e upper' feed-'roll F is positively actuated, thejtwo lower and' independentlymounted feed-rolls Gbein merely idler-rolls. Such Vlosing the case the owen rolls are advanta eously and 'eifectiveiy adjusted orfv move toward andawa'y from they upperroll through the medium of theec'centric-pins H,

as previously explained, It will be readily,

- understood-that itis ofcourse desirablefto 'thus adjust thel rolls relatively to eachother iirorder that the necessary degree ogripon.

the wire may be insured--that is to say, the degree of grip necessary for feeding the wire.' As the two sets of devicesfor driving the two staples are arranged at'opposite sides of the axis of the form, it is evident that, one set f balances thepressure of the other and 'that each counteracts the tendency of the other to rotate the'formthat is to say, the two lines of thrust exerted by the staple-drivers pass at opposite sides oi thefaxiscf relative rotation.y

The different sides of the form are preferably gravity outoi the vstaple-driver and so that the staple formers I equidistant from its axis.l

The springs. h are of `course adapted to be flexed. laterally, so as to disengage their held ends, and thereby relieve the eccentric-pins from-sprin tension and permit' the rolls to separate,- t e arrangement also permitting ready removal of the different parts.
