lVlACHlNE FOR POINTING AND LAPPlNG HOOPS.

SPECIFICATION forming part of Letters Patent No. 305,868, dated September 30, 1884.

q, Application filed .Tuly i4, 1883. (No model.)

To all whom it may concern: i

Be it known thatl, ALEXANDER F. Wann, of Detroit, in the county of Wayne and State of Michigan, have invented neuT and useful Improvements in Machines for Pointing and Lapping Hoops; and I do hereby declare that the following is a full, clear, and crac-tdescription thereof, reference being had to the accompanying drawings, which forni a part or" this specification. y

This invention relates to certain new and useful improvements in the construction of machines designed for pointing and lapping hoops. n

The invention consists, first, in the peculiar construction and operation or" the means and devices employed for pointing one end ofthe hoop; second, in the peculiar construction and4 arrangement of circular. saws for lapping; third, in the peculiar devices, and their operation, employed for automatically feeding the hoopstothe machine from the table;- and, fourth, in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.

Figure -l is a perspective of my improved machine. Fig. 2 is an end elevation. Fig. 3 is a Vertical longitudinal section on thelineY Y in Fig. l. Fig. L.Lis a'perspective view of the point-ing devices. Fig. 5 is a vertical crosssection on the line Z Z in Fig. 2. Fig. 6 is a vertical sectional ele-ration on the lineXX in Fig. l. i

In the accompanying drawings, which forni a part of this specication, A. represents a suitable frame, longitudinally across which, and at therear side thereof, is journaled the shaft B in suitable boxes. This shaft B has properly keyed upon it the two pulleys c c', drive-pulley b, and pulley c, the latter being upon the end of the shaft outside the frame. Motion from this shaft is communicated' by means of the belt C to the pulley D, Whichis mounted upon the short counter-shaft E, one

end of such shaft being j ournaled in aswinging box, F. Upon this `shaft E is secured a friction-pulley, VGr, which,` when the Vmachine is in use, is brought in Contact with the face of the large pulleyH, keyed upon the counter-shaft l by means of the treadle-lever J,

which is connected to one arm of such swingingbox, as shown. The pulley H is connected by. means of a connectingbar, L, to the outer end of a rock-shaft, K, which is properly jourualed in the upper ends of vibrating arms M, vthe lower ends of such arms being pivotally secured at N to the frame..

O represents a rocker-arm, Whichis secured i upon the outer end of the shaft K, and at or near its lower end is provided with a pin, d, which rests upon the upper edge of the pitman L.

l? represents feed -arms,the rear ends ofwhich are rigidly secured to the shaft K, While their 'forward ends are hooked upon their under side, as shown, and these arms are for the purpose of feeding the hoop to the machine upon the guides Q, which are secured upon the table R at the front of the machine.

In advance of the shaft K is secured a rod, S. in standards c, and upon this rod are sleeved the rear ends of the presserarms T, the forward ends of which have pivotally secured to them the presser-feet U, for the purpose here inafter described. A

V represents an iron bracket, rigidly secured to the frame, in the arms of which is journaled a vertical shaft or sawarbor, W, upon the upper end of which is secured the horizontally ruiming saw X, this saw and its arbor being driven by means of abeltrunning from the pulley Ybackl to one of the pulleys c upon a shaft, B.

. Z is an inclined table or bed, rigidly secured to the frame, and such bed extends beneath the sauT X.

is another bracket, which is adjustably secured upon the frame and held to its adjusted position by means of the screw and nut B', Fig. 6, or in any other convenient manner that will admit of the adiustabilit-y of such bracket longitudinally with the frame. This bracket also carries a saw-arbor, G', and a saw, D', motion to such saw and arbor being communicated through the medium of abelt, E, from the pulley ci', which is likewise secured upon the shaft with a rearwardlyprojecting arm, F,in which is pivotally secured the swinging guide-table G', which is inclined, as shown,

and upon one IOO side of this swinging table G there is formed the curved flange H. A spring, g, serves with a constant force to hold the swinging table G in its normal position. p A

I is a bracket rigidly secured to the frame, and to this bracket are secured the guidecheeks J, in which the cutter-head Kihas a vertical reciprocating motion, such motion being communicated through the medium of a pitman, Ii, the lower end of which embraces the eccentric N upon the shaft I. This cutter-head vis provided with a Vfshaped knife, M, the lower corners of which are provided with the-downwardly-projecting spurs o.

O is an arm which is rigidly secured to the bracket I', and this arm carries a il-shaped cutter, P', somewhat smaller than the knife M,"and which is labout ilush with the face of the inclined table Z.

"R is an overhanging bracket, projecting upward from the bracket I', and is provided with the arm 7c Iat its freeend, such anni beingsomewhat pointed, as shown. A jSis a'table rigidly secured to the frame in fron ofl the pointing device last described, and thistable isprovided with a hinged pressen` plate, T.

Having described the construction and arrangement of the various parts of my improved herein described.

, pointer and lapper, I will now proceed to describe its operation. The hoops are laid by 4the operator upon the guide-bars Q on the table It, the inner ends of such guide-bars being inclined. Motion being imparted tQ the device, thc operator depresses the treadle J, which communicates motion from the shaft B to the various parts through the connections The ends of the hoops are placed soy that they rest upon the table S and beneath the presser-plate rI, the gravity of which keeps the ends down upon such table. In the rotation of the pulleyH and the movement of the connections named the rock-shaft 'K is partially rotated, which causes the arms P to rise, while at the same time such rock-shaft advances toward the front of the machine, this movement occurring while the wrist of the I wheel His making the half upward movement.

In the further rotation of the pulley H the. feed-arms I drop over the hoop and draw it back, so that one end rests upon the cutter P. The cutter Mis now,i11 the further operation of the machine, brought down upon the top of the end of the hoop, which points that end, the knife receding, while the arm 7c of the overhanging bracket R prevents the hoop from following the cutter up, the weight of the presser-feet U also tending to keep the hoop upon the guides Q. The feed-arms now again advance and engage with another hoop, when it is drawn back `into the machine and pointed in the same manner as the iirst hoop has been pointed, while the second hook upon the feed`arm has engaged with the first hoop which was fed into the machine and draws it upon the tables Z and G', the gravity of the presser-feet depressing the hoop, as shown in Fig. 3, so that vas the ends of the hoop come in contact with the saws X D the upper por tion of their ends is sawed off at the same operation upon an incline, thus forming the lap. The hoop, being advanced constantly against the saws by the action of therfeed-armsiinally falls off the table onto the floor or into any proper conveyer which may be arranged for carrying it off, but which forms no part of my invention.

It will be seen that should a hoop of greater length than those for which the machine is set get upon the table, were the table G stationary, 'it would necessarily cause abuckling or upward bend of the hoop and make a very abrupt cut, but that in its being adjustable it gives way beforethe end of the hoop, so that the lap is formed the same uponall the hoops.

The adjustability of the bracket A and pulleys a With their connections is so that the device may be employed for pointingvarious grades of hoops from the longer to the shorter.

What I claim as my invention is- 1. In a machine for pointing and lapping hoops, two horizontally running circular saws, each adjustable vertically, and one adjustable on the longitudinal plane of the Inachine toward or from the other saw, to accommodate different lengthsl of hoops, said 'saws being adapted to cut the lap on opposite ends'of the hoop simultaneously, and meclr anilsm for operating the saws, as herein speci* ec.

2. In a machine for pointing and lapping hoops, a rock-shaft, K, provided with hooked feed-arms, and mechanism, "substantially as described, eonnected with the driving-power for raising said arn1s,and carrying the hooked end thereof over and beyond the hoops, and then dropping the points of the hooked en d beyond said hoops to feed the same, as set forth. I

3. In a machine for pointing and lapping hoops, the combination of the vertically-,adjustable saw X, mounted in stationary bearings, and the vertically-adjustable saw D',

mounted in bearings having 'adjustment to or from the other saw to accommodate hoops of varying lengths, and the main shaft B, provided with means for driving two bands,l each of which passesdirectly to a different pulley on the s aw-arbors, so as to be readily adjust! able, as set forth.

4. In a hoop lapping and pointing machine, and .in combination with aI rock-shaft and feed arms, substantially as described, the shaft S, having arms T, and presser-feet Il, pivoted to the'endsof said arms, whereby the feet will securely hold two hoops of varying thicknesses, substantially as set forth.

. 5. In a hoop-lappingmachine, and in combination with the horizontal circular sawX and inclined table Z, the adjustable saw D. and its swinging table G, the guides Q, havnear the other saw, Io

G', and the substantially one saw, swinging bed G spring booting upon the bed guide-bars Q between the saws,

ing inoned surfaces adjacent to the saws, all for the purpose of presenting the ends of the hoops at; an angle tothe horizontal run of the saws, substantlialy as specified. as set forth.
