N4 PETERS. PHOTO-UTHOGMPHER, WASNINGTD D C THOMAS SHAW, OF PHILADELPHIA, PENNSYLVANIA, ASS
TO HIMSELF AND PHILIP S. JUSTICE.
Lette/rs Patent No. 90,6913), dated June 1, 1869.
IMPROVEMENT IN RIVETIG-MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom 'it may concern: Beit known that I, THoMAs SHAW, of thc city ant countyof Philadelphia, Pennsylvania, have invented new and useful Improvements in Riveting-Machines; and I hereby declare the following to be a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention consists in the combination of devices as fully expressed in claims.
In order to enable others to use and practice my invention, I will proceed to describe its construction and operation.
On reference to the accompanying drawing, which forms a part of the specification- Figure 1 represents a top yiew of the' machine,
` and Figure 2 represents a side view of the same. Similar letters refer to similar parts, of whicha is a wood base, to which is secured cast-iron frame I b, on thetop of which is secured, by screws c, cast-iron guide-frame d. Said frame d is provided with journal-boxes, e e, into which shaft f plays.
Said shaft f is provided with crank-disk g, beltwheel h, and fly-wheel i, all for the purpose as hereafter described. ,Y
k and l is an adjustable pitman-rod, 'secured to crank-pin or disk g, and united at the other' end to spring m.
Said spring mis attached to hammer n, by means of links o and belt p, all for the purpose as hereafter described.
Said links areprovided with spool-like bearings, for the prevention of wear, as hereafter described.
Said hammer n is propelled in a horizontal direction in a. V-shap'ed guide in frame d, the back of said guide being constructed of a wedge, fr, which causes hammer to move tightly or loose in said guide when said wedge is moved by means of screw s, tig. 1.
-Said screw s is tapered into said wedge r, but is held longitudinally stationary by a projecting post, t, upon which post said screw s revolves, and is prevented from moving in the long direction by means of collars, allfor the purpose as hereafter described.
uis an iron post secured to the base of frameb, and projects up a sufficient height to support die 1:, opposite a corresponding die, w, in hammer a, for the purpose as hereafter described.
:t is a leather belt, secured at one end to pin y, which is secured to frame d.
lhe other end of said belt is to be secured to the belt-tightener, for the purpose as hereafter described, by mechanism not claimed in this application, and, therefore, not shown in the drawings.
The machine is operated in the following manner:
The shaft fis placed parallel with and immediately under a revolving shaft, which is provided with a pnl ley of sufficient diameter to run pulley h about four hundred revolutions per minute,.when said pulley h. is connected with said driving-pulley by means of belt. v
Said belt-tightener is ofthe ordinary construction,
hinged atthe top of the frame, and'provided with a pulley at the bottom.
Said pulley is caused to press against the belt which propels the machine, by pushing said frame by hand or foot in the desired direction.
Belt as, which surrounds crank-disk g, is to have its loose end connected with said tightener, so that when 'the tightener is moved to'release the driving-belt of pulley h, it will pull upon and tighten belt z, upon the crank-disk, and cause the machine to stop.
The rotation of crank-disk is in a direction that will wind the belt-brake :t upon itself, and thus cause a great friction by a slight pull on loose end of beltbrace.
By the operation of belt-tightener alone, the machine is started and stopped suddenly.
The rotation of said crank-disk gives a vibratory motion to connecting-rod k, equal to throw of crankpm.
by reason of the intervention of spring m, and belt p, and links o, which forms a exible connection, and causes the hammer to vibrate with crank-pin syn# chronously, travelling at double the speed of connecting-rod, and strikes heavy blows in consequence.
The sheets to be riveted are suspended between hammer and post u.
The rivet inserted when the hammer is caused to vibrate, by pressing belt-tightener, as afore described.
After rivet has received sucient number of blows, the machine is arrested, as afore mentioned.
It is necessary that the hammer have no lateral motion; hence the provision of wedge 0', which takes up any wear or looseness of hammer in guides.
The links vo, in combination with the journal-spools in same, are.l of utility in shortening belt `@and in allowing a free and easy motionof this necessary flexible connection.
Rod k enters hollow tube l of connecting-rod, and is held by set-screw, for the purpose of lengthening or shortening said connecting-rod.
The combination ofthe hammer, exible strap, links, spring, eonnecting-rod, and crank-shaft hereinbefore described, I do not here claim, as the same has already been secured to me by Letters Patent; but
' What I do claim, and desire to secure by Letters Pat-ent, is' f 1. Arranging said combination of devices in the manner described, in frame b a, and combining therewith the anvil-post or block fu, and the screw and icNyoR'* The hammersl hasa stroke of double this amount,
, wedge s and c', for preventing lateral play of the harntighten the friction-belt, substantially as and for the mer, substantially as described'. purpose set forth. 2. In combination with the combinations rst men- ITHOMAS SHAW. [SEALL] 4tioned in the foregoing clause the disk g, or am equiv- 'filent pulley, the fricti0n-belt x, and mechanism which \Vitnesses:
