BARREL-HOOP-DRIVING MACHINE Specification of Letters Patent.

Application filed September 22, 1909.

To all whom it may concern.'

Be it known that we, WILLIAM C. STEVENS, of Akron, in the county of Summit and State of Ohio, and ALEXANDER MAcGnEGoR, of Pittsburgh, in the county of Allegheny and State of Pennsylvania, both citizens of the United States of America, have invented a certain new and useful Improvement in BarreLHoop-Driving Machines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

Our present invention relates to machines for driving or setting hoops on barrels, casks and the like.

The object of the invention is the provision of a driving head construction which is simple, reliable and powerful in operation, is not apt to get out of order, can be easily adjusted to barrels of different sizes, and has provisions for readily and positively moving the driving arms radially outward when necessary before and after driving one of the intermediate hoops onV the barrel so that the driving arms will clear the end hoop or hoops of the barrel, while at the same time each driving arm has freedom to aocommodate itself to any irregularity in the contour of the barrel during the hoop driv- Ving operation, but is held against jumping over the hoop being driven.

A further ob'ect of the invention is the provision in a riving head having driving `arms for setting the intermediate hoops of -a barrel, of a suitable resiliently supported presser plate for engaging the end hoop of the barrel and driving it in place either at the same time that the intermediate hoop is being set, or at a different time.

The various features of vnovelty which characterize our invention are pointed out with articularity in the claims annexed to and orming a part of this specification. For a better understanding ofthe invention, however, reference should be had to the accompanying drawings and descriptive matter lnwhich we have illustrated and described in detail one of the formsin which Athe invention may be embodied.

Of the drawings, Figure l is a perspective view showing an entire hoop setting machine exce t a portion of the driving mechanism of t e machine. Fig. 2 is a perspective view, on a Larger scale than Fig. 1,

the like, (not shown), o i which a hoop or hoops is to be driven, is p aced. 0n the base A are supported a pair of pedestals or columns A which are unit ad at the top by a cross piece A2. The driving head, indicated as a Whole by the symbol D, is provided with guides D sliding on ver' ical guide ways or ribs D6 carried by the columns A. The driving head is raised o1 lowered by means of a screw shaft B3 secui ed at its lower end to the driving head, and l Jngitudinally movable through, but held zgainst rotation in, the cross piece A2. An internally threaded gear B2 is journaled in` but held against axial movement in, the :ross piece A2 and serves when rotated to raise and lower the threaded shaft B3. The gear B2 is provided with beveled gear teeth meshing with beveled gear B carried by t ie driving shaft B. It will be understood that suitable provi' sions are made for rotatf ng the shaft B in one direction or the othe r accordingly as it is desired to raise or low 1r the driving head D. We have not thought it necessary to illustrate in detail the co istruction whereby the shaft B is given the desired rotation in one direction or the other, as clutch mechanism for this purpose is well known in this art. It will be sulii cient, therefore, to call attention to the fact that clutch mechanism may be operated lo stop the shaft B or rotate it in one dire ation or theother through the hand lever X rod X, bell crank X2 and rod X, and that L rod X4, connected to the bell crank X2 and provided with co1- lars Xls and X, and an arm Dx carried by the' head D and adapted to en age the collars X5 and X6, are prow ided or automati-` cally shifting the clutch :nechanism to limit the extreme up and dowr movements of the head D. Weights Y, ve ftically movable in the columns A are provi( Led for counter balancing the weight of th head D to which they are connected by corl ls or cables Y running over the pulleys Y2 The driving head D cc mprises a disk like body portion D2 having a central hub or axially extending portior D. In` the upper end of the latter portici the lower end of the screw shaft 1121s is secured. The body portion D2 is formed with a plurality of radial channels or guide Ways D" at its outer portion, and at the inner end of each guide way D3 is provided with a pocket D5 open at the upper side to receive a spring E2, and the projecting end of a rod E', b means of which a pivot or thrust block i, slidingly received in the corresponding guide way Da is normally held at the inner end of the guide way as shown in Fig. 3. Each block E is slotted to receive a corresponding driving arm F, which is pivoted to the block 4by a pivot pin E2. The walls of each guide way D3 are slotted at top and bottom to permit the passage of the corresponding arm F. Each driving arm carries at its lower end a driving shoe F', preferably swiveled on the arm. The upper end of each arm F is pivotally connected by a fulcrum pin G to the outer end of a corresponding link G. The inner ends of the links G are pivotally connected by pins G2 to ears formed on a collar or ring like member H which is slidingly mounted on the hub portion D2. To accommodate barrels of different sizes the links may be so formed as to permit of an adjustment of their effective lengths. As shown, this is accomplished by forming two sets'of holes in the outer ends of the links in which the pins G may be placed as desired. The member H is provided with hand trunnion pins H', to which are pivotally connected the bifurcations I of lever I. The latter is fulcrumed on the disk D2 by means of a link J pivotally connected at its upper end to the lever I, and pivotally connected at its lower end to a block or bracket J secured to the upper side of the disk D2. By turning the hand lever I on its fulcrum, the member H may be moved from the position shown in full lines in Fi 3, to the position shown in dotted lines 1n that figure, and in full lines in Fig. l. When the member H is moved into the dotted line position of Fig. 3, the pivot ins G2 are lowered, and the fulcrum pins G for the driving arms F are moved outward, thus throwing the driving-shoes radially inward. Attention is directed to the fact that the movement of the lever I is preferably such that the pivot pins G2 are thrown slightly below the pivot pins G when the member H is moved into the dotted line position of Fig. 3, so that the thrust on the pivot pins G', when the driving shoes F are moved ra. diall outward, does not tend to move the mem er H upward. When driving a quarter or bilge hoop, that is an intermediate hoop, on a barrel or cask, the driving arms are thrown out, as shown in Figs. 2 and 3, until the driving shoes F are moved below the upper end of the barrel and the end hoop thereof, if the latter is in place, as is usual, although it may not yet have been driven home. After the driving shoes pass-below the top of the barrel, the hand lever I is operated to move the member H down and force the fulcrums G for the driving arms F radially outward. This brings the driving shoes into contact with the barrel, and the parts should be so proportioned that the driving shoes will engage the periphery of the barrel before the fulcrum pins G are given their full outward movement so that when this outward movement of the fulcrum pins is completed the thrust blocks E will be moved radially outward from the inner ends of the guide Ways D2, thus putting the springs E2 under tension. The result of this is, of course, that the driving shoes bear resiliently against the periphery of the barrel and tend to draw it into the desired circular form. On the continued downward movement of the driving head, the driving shoes engage the quarter or bilge hoop, and force the latter into place. The resilient manner in which each driving shoe engages the barrel hoop revents any liability of individual driving s oes jumping over the hoop being driven. The construction thus permits practically any style of hoop being driven, and We may remark that the machine shown can be used without change in driving many different styles of hoops, but is particularly designed for driving the well known spiral wire hoops.- When the hoop engaged by the driving shoes has been driven far enough the handle I is operated to slide the member H upward on the hub D4, thus drawing the fulcrum pins G inward and permitting the driving shoes to separate from the hoop be ing driven, and the periphery of the barrel sufficiently to clear the end hoop of the barrel when the head is thereafter raised'. It will be observed that while the tension. of the springs E may be such that the driving shoes are urged radially inward against the barrel with any desired degree of force, when the member H is down, the latter can be shifted through the lever .I by a comparatively small force. The reason for this is two-fold. The mechanism by which the member H and fulcrum pin G is adjusted does not take the driving thrust of the driving arms. On the contrary, that is taken directly b the disk like body D2 through the thrust blocks E. Moreover the fulcrum links G are so arranged that the leverage is a very powerful one when the fulcrum pins G are in or near their outer positions.

In order to drive home the end hoop of the barrel either on the same downward stroke of the driving head in which the quarter or bilge hoop is driven into fplace, or on an independent stroke, we pre erably provide the resiliently supported presser plate L as shown. This presser plate is provided with a centrally located spherical seat on its under side for a washer K having its upper side spherical. The washer K surrounds a bolt K provided at its lower end with adjustable locking nuts K2. The bolt K passes up throu h the pressure plate L into the lower end o? the hub portion D* where a cavity is provided receiving the enlarged head K3 of the bolt K. The bolt K thus serves to limit the movement of the pressure plate L away from the main driving head member, while at the same time the plate has capacity for adjusting its plane relative to the lane of the disk body D2. Between the disk body D2 and the presser .plate L are Aarranged a plurality of presser springs L2 which have f their upper and lower ends receivedv in correspondingA bosses formed on the underside of the disk D2 and the upper side of the presser plate L.

While in accordance with the provisions of the statutes we have herein described and illustrated the best forms of our invention now known to us, it will be apparent to those skilled in the art that many changes .may be made in the form of the apparatus disclosed without departing from the spirit of our invention and that certain features may sometimes be advantageously employed without a corresponding use of other features.
