ALBERT HIRSHHEIMER AND CHARLES M. MUELLER, OF LA GROSSE, WIS.
MACHINE FOR INSERTING- HARROW-TEETH.
SPECIFICATION forming part of Letters Patent No. 325,542, dated September 1, 1885.
Application filed June 16, 1885.
To all whom it may concern.-
Be it known that we, ALBERT HIRSHHEIMER and CHARLES M. MUELLER, citizens of the United States, residing at La Orosse, in the county of La Grosse and State of Wisconsin, have invented a new and useful Improvement in Machines for Putting Teeth in Harrows and Mortising out Holes in' Timbers for this or Similar Purposes, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which our invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a perspective of the front or face of our improved machine with a harrow-timher in position beneath the face of the presserdie which forces the teeth into place in the timber. Fig 2 is a crosssection on line a: m of Fig. 3, showing how the timber is clamped to prevent splitting, and also showing the co centric on the main shaft, which eccentric serves to throw the lever-arm of the compressor out, and thus cause the same to tightly clamp the timber, as will be hereinafter fully explained; and Fig. 3 is a top view. 7
The object of our invention is to provide a machine which shall serve as a means of securing teeth to the timbers of a harrow by machinery, thus saving time and labor.
Another object of our invention is to provide a means of securing the teeth to a timber which has been painted and varnished without injuring or scratching it; and it consists in the construction, combination, and arrangements of parts, as will be hereinafter fully explained, and specifically pointed out in the claims.
In the drawings, A designates the main shaft, which is mounted on a suitable frame, and it receives its motion from the pinion a, which is on the pulley-shaft b. B is an cecentric-cam on the shaft A, which serves to operate the lever-arm c-of the compressor C. D is a drivewheel, to the outer face of which is secured a crank, (1, near its periphery. Upon this crank (Z is mounted a pitman-rod,
. e, that operates the presscr-die E, and which reciprocates vertically in the guides f f.
To the lower end of the pitman-rod e is se- (No model.)
cured a secondary pitman-rod, g, which is also pivoted to an adjustable set-screw or bolt in a slot, 72, in the lever-arm i. The object of this adjustment is to adjust the hook to operate upon teeth set at different distances apart in the barrow-timber. This lever-arm i is secured at its upper end to the pin 7' on the bracket K, and at its lower end is pivoted to a third pitman-rod, Z, which is also pivoted at m to the plate a, that reeiprocates horizontally in the guide-trough 0. This plate and guidetrough may be correspondingly tongued and grooved or dovetailed to prevent accidental displacement. On the top of the plate a is also pivoted at mahook, p, which is provided at its free end with a notched catch, 9. On the outer edge of this hook is an elongated slot, r, which fits over a projection, s, on the plate a, and near the inner edge of the hook p is an eye, 25, through which passes a spring, a, said spring passing around the pivot m and bearing against the projection 8, thus tending to keep the hook p always snug up to the teeth on the harrowtimber, as will be clearly seen in Fig. 3. It will be observed, however, that when the hook is in its normal position the projection s is at the outer end of the slot 1", and when pressure is applied to the face of the hook said hook is free to be forced back the length of the slot 1, the purpose of which will be explained hereinafter.
By reference to Fig. 1 it will be observed that the table F supports a binding-guide, G, which is held in place on the table by bolts w, which are secured to the table through the slots at a, and held in place by suitable nuts and washer. By providing the slots a a it will be seen that the guide G is adjustable laterally toaccommodate timbers of different widths. b b are set-screws, mounted on the table F in the brackets c o.
By reference to Fig. 2 it will be observed that the compressor is secured to the lower extremity of the leverarm c, which is pivoted at d to the double bracket 0. upper free end of this lever-arm o, is a hole for the reception of a spring, g, which serves to throw the compressor away from the timher after the tooth has been forced into position in the timber. Just below this hole is a pin, it, which projects at right angles to the lever-arm 0. Upon this pin h is loosely journaled a friction-roller, 17, which revolves over the undulating face of the eccentric-cam B.
H is a guard secured to the upper portion of the main frame to prevent the lever-arm c from being thrown out of engagement with the eccentric-cam B'while the machine is in operation.
Byreference to Fig. 1 it will be observed that the table F is provided with aslot,I,which extends from a point beneath the presser-die to that end of the table where the timbers are taken from the machine after the teeth have been put into them. This slot is to allow the timbers to be moved along on the table after the teeth have been forced into position, the latter extending below the timber and moving through the slot.
The operation of our machine is as follows: The timber is placed on the table at the end opposite that which contains the slot, and the points of the teeth are stuck into the holes in the timber. Then the timber is pushed under the presser-die just far enough to allow the hook p to slip over the first tooth. The machinery is then set in motion and the work begins. The presser-die is forced down upon the tooth and drives it home, the pitman-rod 9 operating the lever-arm 43, which in turn operates the pitman-rod Z, that also operates the plate a, to which is secured the hook p, which latter is moved toward the next tooth till it loops over the latter. Now, when the presserdie is in this position, the longest portion of the eccentric-cam B is directly in front of the frictionroller on the lever-arm c, and the latter is forced back at its upper end, while the lower flattened end, forming the compressor 0, is pressed tightly against the timber, as will be clearly seen in Fig. 2. As the motion of the machinery continues the presser-die is raised, the hook 1) moved for ward, carrying the harrow-timber with it by the tooth, the compressor 0 is thrown back away from the timber, and thus the work eontinues, and the operation is repeated as often as is desired.
It is obvious that by the employment of our machine much time, labor, and money are saved. The timbers can be all finished before the teeth are put into them, which renders it much easier than it would be to have to work them with the teeth in them.
By the novel arrangement of our compressor we firmly hold the timber in place, and also avoid the danger of splitting it while the tooth is being driven home.
It is obvious that this machine might be used to advantage in holding timbers in place and mortising them for this and similar purposes. It is also obvious that the machine might be elnploycdin securingjpins to various 7 devices besides barrows-such as ladders,
rakes, &e.
Having thus described our lnvention, what we claim as new, and desire to secure by Letters Patent, is p 1. The combination, with the main frame, the shaft mounted on its top, a drive wheel on the end of the shaft, and suitable gearing for operating said shaft, of the presser-die, apitman connecting the presser die with the drive-wheel, the slotted lever-arm pivoted to the frame, a pitman-rod connected to the press er-die and operating the lever-arm, and apitman, 1, adapted to engage a hook' and cause the latter to advance the barrow-beam a distance about equal to the space between the harrow teeth, substantially as herein described.
2. The main frame, the shaft journaled in its upper porti0n,the drive-wheel on the shait, the presser-die, and a pitman-rod, 0, connected to the drive-wheel and operating the presser die, in combination with the pit-man-rod Z, the connections 9 and 13,0perated by the presser-die, the hook 1), provided with a slot, r, a horizontally-sliding plate to which the hook is secured, and a spring connected to an eye on the sliding plate, and bearing against a pin, 8, whereby the beam is advanced and the hook automatically placed in position to advance the next succeeding tootlnsubstantially as herein described.
3. The frame, the main shaft mounted in its upper portion,and the driving mechanism, in combination with the cam B, mounted upon the shaft, a compressor pivoted to the frame and having on its upper end a friction-roller adapted to engage the face of the cam, and a spring bearing against the upper arm of the compressor to force the lower end of the same from the beam, a horizontally-arranged table, and an adjustable binding-guide mounted on the table, substantially as and for the purpose described.
4. The horizontallyarranged table provided with a slot in which the beams move, and anadjustable guide mounted on the table and adapted to have a transverse movement thereon, in combination with the presser-die,apitman connecting the presser-die with a drivewheel on the main shaft, the main shaft, the cam mounted thereon, and a compressor operated by the cam, whereby the teeth are driven, the compressor held against the beam, and the beam advanced a distance about equal to the space between the teeth,substantially as herein described.
