SPECIFICATION forming part of Letters Patent No. 584,142, dated J une 8, 1897.
Application tiled December 28, 1896. Serial No. 617,166A (No model.)
To @ZZ whom, it iii/ay concern: A
Be it known that we, PHILErUs W. GATES and CHARLES L. Cani-IAN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stone-Crushers, of which the following is a specilication.
Our invention relates to that class of stonecrushers and rock and ore breakers known in the art as reciprocating-jaw breakers, and is intended to be an improvement upon the invention described and claimed in Letters Patent No. 530,037, granted to us December i, 1894.
The object of our present invention is to provide a simple, economical, and eliieient stone-Crusher of the reciprocating-jaw type 3 and the invention consists in the features, combinations, and details of construction hereinafter described and claimed.
In the accompanying drawings, Figure lis a perspective view of a stone-Crusher constructed in accordance with our improvements,showin g a portion of the hopper broken away; Fig. 2, a central longitudinal sectional elevation thereof, and Fig. 3 an end view thereof.
In the Letters Patent above referred to the construction of the Crusher therein described is such that the motion of the reciprocating jaw can be changed from the greatest motion at the top and smallest motion at the bottom to the greatest motion at the bottom and smallest motion at the top. We have discovered that in order to obtain the best results for the crushing of all kinds of material it is necessary to design, construct, and arrange the mechanism so that any amount of motion desired can be imparted independently to the top and bottom of the jaw, according to the character of the material to be operated on.
In the art generally it is well known that the amount of motion given to either end of the jaw governs the amount ot' motion for the entire jaw, and while it has been possible by the use of wedge-blocks and other mechanism to change the amount of motion at one end of the jaw the motion at the dierent points along the entire jaw is governed arbitrarily bythe amount of motion given to the jaw at the point where poweris applied. Our present invention is designed, primarily, to obviate the objections found in these mechanisms and to provide a simple, economical, and eiticient stone-crusher of the class described in which the reciprocating jaw may have a maximum amount of motion at the top and a minimum amount of motion at the bottom or a maximum amount of motion at the bottom and a minimum amount of motion at the top, or the jaw can have a substantially parallel motion or any motion iutermediate the three motions above alluded to. In other words, the motion at either the top 0r bottom of the jaw can be provided for independently of the other.
In constructing a stone-erusher in accordance with our improvements we provide a main frame A of the desired size, shape, and strength and adapted to contain and support the operative mechanism in position. This frame is provided with a stationary jaw B, which may be secured therein in any desired manner. Upon this frame portion we mount a reciprocating jaw C on a reciprocating rollingpivot D. To impart motion to this reciprocating jaw, We provide a lever, E with its fulcrum or pivotal point preferably on the upper portion of the frame at e. This swinging lever, or operating-lever, as we prefer to term it, is provided with a series of bearing-grooves e', e2, e3, ci, e5, e, el, and e8. An eccentric shaft Gr is provided mounted in suitable bearings transversely of the main frame and is provided with the usual driving and balance pulleys g and g'. Mounted upon suitable bearings upon the eccentric portion of this shaft is a pitman H, which engages with a groove E in the lower portion of the operating-lever.
The reciprocating jaw is provided with grooves c at its upper end and c at its lower end, and tension-bars I and K are provided having cross-heads 't' e" and 7c 7d, the crossheads and k being arranged in the upper and lower grooves of the reciprocating jaw, respectively, while the cross-heads t" and 7e are arranged in the bearing-grooves c and eS on the rear surface of the operating-lever. A tension-spring M, 'formed of rubber or any ICO other desired material, is attached to the reciprocating jaw at the front portion thereof and to a solid portion of the frame, so as to gire or impart to such jaw a backward motion and at the same time keep the crosslieads of the tension-bars in operative engagement with the jaws and operatinglever, respectively.
The foregoing arrangement of parts is such that as the eccentric shaft is revolved the pitman imparts a motion to the operatinglever. It will also be seen from an inspection of the drawings that the greatest motion of the operating-lever is at its lowest end, and that such motion decreases gradually until it dies out when it reaches the fulcrumpoint of such operating-lever. The tensionbars as arranged in the drawings impart the greatest motion to the reciprocating jaw at the lower end and the minimum motion to the upper end thereof. It will be readily seen, however, that since the amount of motion of the operating-lever variesin its motion from the bottom to the top the amount of motion given to the reciprocating crushingjaw will coincide exactly with the position that the tension-bars assume in their en gagement with the rear portion of the operatinglever. For instance, to increase the amount of motion at the top of the reciprocating crushing-jaw all that is necessary to do is to insert the crosshead 7a in one of the lower bearing-grooves.
It will thus be seen that while the amount of motion given to the upperend of the reciprocatin g crushing-jaw has been increased the amount of motion given to the lower end of such jaw has not been altered in any manner whatever. If desired to give the reci procating crushing-jaw a substantially parallel motion, the crosshead i of the lower tensionbar may be placed in the operating-'groove e4 and the cross-head 71; of the upper tension-bar may be placed in the groove e5.
Ve have preferably constructed the crossheads of different relative widths, so that one set of tension-bars may operate outside the other when such tension-bars are arranged in cross relation to each other. (See Fig. 3.) This arrangement is provided so that the maximum amount of motion may be imparted to the upper end of the reciprocating jaw by placing the cross -heads 7o in the bearinggroove es, and the minimum amount of motion maybe given to the lower end of the reciprocatin g crushing-jaw by placing the crossheads il in the bearing-groove c. It will thus be seen from an inspection of the drawings and from the foregoing description that any desired amount of motion may be given to either end of the jaw independent of the motion given to the other end.
The advantages derived `from the use of a machine constructed in accordance with the foregoing description are such that different materials of different densities and degrees of hardness can be operated on successfully by one mechanism. For instance, it is well known in the art of breaking stone that the great object to be desired is to be able to proportion the amount of motion to the jaw so that the material as it is operated on will be just fractured or broken and not crushed beyond this point. Otherwise an unnecessary amount of power would be used. There the stone is hard and friable, a much smaller amount of motion is required than where the stone is soft and capable of being pinched or compressed before fracturetakes place, as instanced by hint-rock and damp sandstone, respectively. With our' arrangement of mechanism the amount of motion given to the top of the jaw may be adjusted to suit the large pieces of any kind of material which can be broken, and the motion of the lower end of the jaw can also be adjusted independently to furnish the amount of motion necessary to continue the fracture of the pieces as they are gradually reduced in their passage from the top to the bottoni of the jaw. The amount of motion, therefore7 is always adjustable to the character of the work being done, and at no time is there more motion at any part of the jaw than is consistent with the work. The product is thus not only much more uniform in character, but no power is wasted in compressing or crushing the material beyond the point which is absolutely necessary to produce the fracture.
While we have described our invention with more or less minuten'ess as regards details and as being embodied in certain precise forms, we do not desire to be limited thereto unduly any more than is pointed out in the claims. On the contrary, we contemplate all proper changes in form, construction, and arrangement, the omission of immaterial elements and the substitution of equivalents, as circumstances may suggest or necessity render expedient.
We claim- 1.
