combined with low cost of manufacture and low cost of operation.

With the above and other objects in View the invention consists in certain novel detailsV of construction and combinations orV par-ts herein-after fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from they spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming' part of this specification, Y

Figure 1 is a longitudinal sectional view through the Crusher' taken on the line 1-1 60 Figure 3,

Figure 2 is a plan view of the crnsher' with the hopper removed,

Figure 3 is a cross-sectional view of the Crusher taken on the line' 3 3 Figure 1, and 65 Figure 4 is a `fragmentary sectional View taken on the line 4 4: Figure 1, showing the lining plates of the cruslier head.

Referring now to the drawings' in which like characters of reference designate similar parts in the various views, the Crusher isv shownl to comprise a casing preferably formed in three sections, the upper section compri-sing a'A hopper 10, the central section compris-ing. side walls 11, and a base section 12. All of these sections are preferably detachable from' each other and are secured to' get-her by bolts 13 passed through suitable flanges 14 carried by the sections at their meeting edges. y

A pair oieanvils 15 are pivoted to the side' walls 11` of the casing below the hopper, each anvil being provided with spaced ears 16 on the outer face which receive a pivot shaft 17, the ends of. which are journaled in suitablev bearings 18 formed in the side walls' 11. It. will be noted that there are a plurality of these bearings 18v so that the pivot shaft may be removed from one set of bearings and inserted in another setin order to va-ry the` width of the spaces between both. anvilsk and. the Crusher head as will` be hereinafter described in detail.

-VThe anvi-ls 15 slope downwardly and outwardly below'the hopper 10 anddivergefrom their pivoted upper ends towards; the base; section. 1Q as best showin in Figure: 1*. The" anvils are furthermore yieldably secured at the' lowerl ends to the. side walls 11A of the ings 30 formed in the side walls 11.

casing by mechanisms which will now be described.

Each anvil is provided with a pair of spaced cross bars 18 and 19, the cross bar 18 being preferably bolted to the anvil as shown at 20. A pair of bolts 21 are secured in lugs 22 carried by the l-ower section 12 and pass through openings formed inboth cross bars 18 and 19. Strong helical springs 23 are disn posed on the bolts between the cross bars 18 and 19. The bolts thus secure the anvils to the casing and also perform the function of guides upon which the lower cross bar 18 may move outwardly against the pressure of the springs 23 to permit the escape of non-crushable material without injury to the crusher.

Supplemental guides '24 as best shown in Figure 2 are secured to the lower cross bar 18 of each anvil and are slidably received in a openings formed in the upper cross bar, there 1 1 liner of corres ondino' thickness ma be substituted for the purpose of varying the width of the space between each anvil and the crusher head.

The crusher head 27 is preferably formed of a casting of triangular contour, the sides of whichare rather steeply pitched and diverge downwardly and outwardly from the hopper towards the base section 12 of the casing. The bottom face of the head is curved upwardly as shown at 28 for a purpose which will presently appear. The head is pivoted near the upper end to the side walls 11 of the casing by means of a pivot shaft 29 passing through the head and through suitable bearrlhe crusher head is oscillated back and forth on the pivot shaft 29 and coacts with the anvils 15 in crushing material gravitating into the spaces between the anvils and crusher head from the hopper 10.

For oscillating the crusher head a shaft 31 is journaled in suitable bearings 32 in the base section 12 and passes therethrough, the shaft being equipped at one end with a belt 1 pulley and at the opposite end with a fly wheel 34. Disposed centrally on the Shaft is a cam sleeve The cam sleeve is rigidly secured to the shaft 31 in any preferred manner.

A block 36 is provided with an eccentric opening 37 to receive the cam 35. The block is connected to the opposite sides of the crusher head by means of links 38, these links being arranged on opposite sides of the i shaft 31 and one being arranged above the shaft and the other being arranged below the shaft. By this arrangement of the links when the block 36 is oscillated by the cam 35, the links will exert an alternate pull upon the crusher head to oscillate the saine.

The links 38 preferably are passed in between hinge ears 39 on the eccentric block and also between hinge ears 40 formed on the crusher head. Pivot pins 41 and 42 are passed through the hinge ears on the eccentric block and onthe crusher head respectively to pivotally secure the links to these parts.

Lubricating cups 43 are arranged to lubricate the pivot pins of the links and the shaft 31 and are fed through flexible tubes 44 passed through the sides of the sections 11 and 12 of the casing. The pivot pins are also preferably provided with bushings 45. Furthermore, it is intended in practice to protect the pivots of the links 38 with leather boots which may be o-f any desired type.

It will be here noted that the upwardly curved lower wall 28 of the crusher head houses the cam shaft 31 and eccentric block 36 so that these parts are protected from injury.

By referring now to Figure 1 it will be seen that a plurality of plates are arranged in staggered relationship in the hopper 10, there being a central plate 46 disposed above the crusher head 27, and also there being side plates 47 disposed below the plate 46 and extending above the anvils 15. Material dumped into the hopper will be delivered onto the central plate 46 and from thence rolls off onto the side plates 47 and from thence gravitates into the spaces between the anvils 15 and working faces of the crusher head 27. Thustwo equal streams of material will gravitate between the crusher head and the anvils and will be crushed at the same time.

Obviously, by moving one or both of the anvils 15 outwardly by adjusting the pivot shafts 17 thereof in selected bearings 18 the spaces between the crusher head and the anvils will be widened to crush material to other sizes than ordinarily. The proper width liner 26 must be used when any adjustment of the pivot shaft 17 is made in order that the working faces of the anvil and confronting working face of the crusher head will remain nearly parallel. However, for a slight adjustment, liner 26 may be changed independent of the pivot shafts 17.

It will be here noted that by adjusting one of the anvils to maintain a narrow space between it and the confronting face of the crusher head while the opposite anvil is disposed to produce a wide space between it and the confronting face of the crusher head, two different sizes of crushed material may be simultaneously delivered.

Arranged below the base section 12 of the crusher there are two chutes 48 which re- 5 loe ceive the gravitating crushed material from the anvils.

In order to promote long life of the parts' both anvils are preferably faced with plates i9 of manganese steel or other wear-resisting material backed with Zinc, and likewise the working faces of the crusher head are faced with similar plates 50. Furthermore, the top of the crusher head is faced with a plate 51 of similar wear-resisting material. The inner faces of the casing sides l1 are also faced with similar plates 52. All of the wear relfisting plates are preferably removably se- ;ured in position by screws 53. Furthermore, the facing plates of the crusher head, anvils, and casing sides are turned over the end faces of the respective parts to provide flanges 54 which are secured in place by screws 55. lt will now be apparent that should tramp iron or other non-crushable material fall into the crusher between the crusher head and anvils the springs 23 and 25 will yield under impact of the non-crushable material and permit the same to pass from between the crusher head and anvils without danger of injury to any of these parts. From the above description it will be seen by virtue of the steep pitch of the working faces of the crusher head that when the cam shift- 31 is driven at comparatively high speed a great quantity of material may be crushed in minimum time. This great capacity of the crusher is produced without danger of breakage to the parts due to the novel construction and arrangement thereof as above described. It will be further noted that the crusher is formed of a few simple, rugged and durable parts which are not expensive to manufacture and will not easily get out of order.

It is thought that from the above description the construction and operation of my invention will be easily understood.
