Appl'latml. filed September 2., 1903. Serial No. 171,593.
." /LZZ tchou/t it Tita/y. concern: Be it known that I. ELIAS GUNNELL, a 'citizen of tv .e United States', residing'at C .icago,
inthe State of Illinois, have invented certain provide a hollow cylindrical adjusting mem-l ber 7 a wi .ich is closed at its inner end an proyided with a piston-like head 7 provided with. proper packing and designed to move new and useful Improvements in Holders-On i longitudinally' in t e cylinder 4 under the l pressure admitted throughL the cock 6.
for Riveters, of which the following is a speciy cat'ion.
My invention relates to riveting apparatus screw guide ring is inserted in the forward. j end of tite cylinder .wi .ich also prevents the and particularly to the means for supporting l removal of the member 7 a.
the rivet in place w- ,ile it is being operated upon by the riveting'tool. The objects of theinve'ntion are, to provide a pneumatically-operated support wlichr is easily adjust-- able to place and provides for receiving the impact upon the rivet; to provide a pneumatically supported rivet set with means for moving it to adjust into osition and resilientmeans for-taking up the recoil of the impact, and to generally improve the structure and operation of holders-.on for riveting and the like. These objects, together with other l advantages which will hereinafter appear, I
attain by means of the construction illustrated j Figui-el Y forms in the accompanying drawings, wherein is a central vertic al section through my preferred form of the holder-on. Figure 2 is a central longitudinal section of a modifi d form, in which is supplied an elastic fluidv support for the adjusting member, and a spring for supporting and actuating The impact member in this instance surrounds and is free to slide uponthe adjusting member.
Figure 3 is a similar view of a still further modified formy of the device wherein the im-- in preferred kpact'member ,reciprocates within the adjustme member, es in Figure l, vand is supported and actuated by a spring as in Figure 2.
recoil by the hammer upon the rivet. bine these y two motions conveniently and For. the proper operation of such tools it is necessary to have a considerable motion longitudinally to adjust the rivet set in proper place Lover the rivet, and also to havev a limited motion for the immediate impact part Yto I comcompactly and operate them bothbymeans of steam or air or other fluid pressure by i means of the structure illustrated. Referring first to Figure 1, the cylinder 4 is provided at its rear end with a head-5 which has Vay laterally extending sleeve receiving a pipe at in Said figure.
which may be provided with any convenient form of cock for introducing and allowing escape of the iluid therein, such as illustrate Within the cylinder 4 I entire holding position abutting against the rivet which is. i f supposed to be receiving hammer blows .upon
its opposite end, it being observed that the device rests upon the floor or some support by 11 screwed into the bottom of the cylinder head 5. The inner end of the impact member 8 may' be provided conveniently with a Split Spring ring and prevents the member 8 from being pus ,l
ventirely through and out of the member 7 t, .as will be evident.
The' cylinder is provided with a convenient form of handle such as 10 yvhich is held by rings embracing the cylini er 4.
It will be observed that' the head 7 of the adjusting member presents to the actuating fluid a larger surface than the impact member 8 so that in placing the apparatus in position for operation the rivet set`9 will be pushed up i-nto place by the combined motion of the member 7 a and member 8, and that in operation when a blow is struck` upon a rivet and the imp act takes effect upon the rivet set 9 this impact may be taken up by the 12 which sets in a groove hed means of the center point wei ht of the impact member 8 andwill imme iately be followed by a return or reflexed blow by the member 8 acting under the fluid pressure; this will insure keeping the rivet tight against the sheet metal into which it is being placed and also assist in the settling and properly forming the head of the same by. means of the recess Vin the head of the` rivet Set 9.
In the other figures I have illustrated the use of a spring to perform one of the two functions necessar cylinder 4 is provi ed with ahead 5 and inlet as before and` he adjusting member 18a is "Ihus in Figure 2 the- IOO IOS

mounted as the stem of the piston head 18 eXit of the impact member 16, and the tube subjected to the pressure, and within this and this alone is exposed to the fluid pressure. Surrounding this adjusting member 18a is a tubular impact member 19 which is also provided with a guiding flange at its in. ner end to engage the cylinder and is supported directly against the rivet set by means of coil spring 15, which rests against the piston head 13. In this case the immediate impact uponthecrivet set may be receivedl upon the impact member 19 and the return stroke and constant contact of the same is provided for by the spring 15.
In the form shown in Figure 3 the position of the parts is reversed, that is the pistonalso engage the rivet set head 20 of the adjusting member 13 is alone member 13 is disposed a coil spring 15 which at the top supports the impact member 16 against which the shank of the rivet set 9 rests directly. The end of the tube 13 is closed by a block 17 in order to prevent the 13 is attached to the piston head 20 by pins 14, as will be understood. In this form of the device the longitudinal motion for adjusting the rivet set to proper height and position is supplied by the long movement of the member 13 and its head 20 within the cylinder 4, while the immediate impact upon the rivet set 9 is taken by the impact member 16 which is held against the spring and which may provide for the return' stroke When the hammering action takes place. Either of these forms may be provided with any desired means for introducing and exhausting the iuid pressure therein, and I desire it to be understood of course that I may use hydraulic pressure as well as gas or steam pressure, as may be more convenient.
In this apparatus it will be observed that I attain an extended range of movement in order to adjust the rivet set to its place and any desired pressure may be exerted thereon; at the same time the proportion of pressure eX- erted upon the impact member is proportionally the same whatever may be the pressure upon the adjusting member.
The operation, and the many advantages of the device, will be readily apparent from the drawings to those familiar with the art.
Having thus described my invention and illustrated its use, what I claim as new, and desire to secure by Letters Patent, is the ollowing:
1. A holder on for riveters, comprising an 'adjusting member engaging the rivet set and an impact member carried thereby but movable independently thereof` and adapted to to receive shocks, together with resilient means for holding both members against the rivet set.
2. A holder on for riveters, comprising a iluid pressure cylinder, an adjusting member therein adapted to engage the rivet set and having a long range of movement, an impact member carried by said adjusting member and resiliently supported but movable independent oi the adjusting member for a comparatively short distance and adapted to take the direct impact of the rivet set.
3. A holder on for riveters, comprising a cylinder and a fluid pressure actuated adjusting member therein having a shank to engage the rivet set, aV movable impact member adapted to move with said adjusting member and capable of being moved relatively thereto to engage the rivet set, together with a resilient support by which the impact mem ber is supported in part by the adjusting member.
4. A holder on for riveters comprising in combination a cylinder and a fluid pressure supply and controlling means, an adjusting member in the cylinder having a shank to engage the rivet set, and an impact member resiliently supported and guided by the adjusting member and also adapted to engage the rivet set. j y v -5. A holder on lior riveters comprising in combination a cylinder and means for introducing Huid pressure therein, an adjusting member inthe cylinder, said member being provided with a shank and having a long range of movement for adjusting the rivet set, and an impact member carried on said shank and spring supported thereon for slight movement along the shank, and adapted lor engagement with the shoulder of the rivet set. 6. In a holder on for riveters the combination of a cylinder and cylinder head .having means to introduce and exhaust vfluid pressure, an adjusting member movable in, the cylinder and having a part engaging the rivet set, together with an impact member movable in the cylinder independent of the adjusting member to a slight extent, and also adapted to engage the rivet set to take the impactI thereof.
In testimony whereof I have hereunder signed my name in the presence of the two subscribed witnesses.
