o'rrs mrnnsnnnz. or. nnoonnr, m You 'ABTIOLE HANDLING IAQHJI'Ev Application nletbgeptember I1, 1928. Serial No. 805,885.

This invention relates to improvements in article or material handling devices-and 'machines and may include practically all of the novel mechanism shown, described and, claimed in my co-pendinga plication filed March 26, 1927', Serial No. 18 ,690, the pres ent invention including improvements thereover, more particularly intended for adapting the machine for handling brick in a brick 13 yard or elsewhere, although the invention is not restricted to that pur ose. In my said previous application the is applied to a tractor, for example, as the well known McCormick Deering or Fordson tractors and the present invention may be likewise adapted to facilitate transporting of moving brick to or from the kiln, to trucks, cars, etc.

One of the objects of the present invention is to provide a rugged lifting arm or finger which is preferably pivoted to and forms part of an elevator or lifting mechanism, the said arm preferably being so proportioned as to be readil engageable with a brick or other carrier, or supporting and elevatin thesame in horizontal position.

Another object is to provide a special carrier or pallet for brick which may be either P engaged by a lifting arm for raising or lowering, or may be raised from the arm and lowered by suitable hoisting apparatus which may be embodied in a crane, for example,

preferably a full-circle swinging crane, such, for example, as disclosed in my aforesaid application.

Another object of the invention is to rovide a lifting arm for supporting a bric or other carrier, which arm is tiltable to one side or the other so as to dump the material to either side of the arm.

Other objects of the invention are to provide a brick handling machine preferably comprising a motor truck or tractor, and which truck is provided with a. lifting arm whichmay be moved down close to the ground or below its level so that the truck when backed up will quickly and properly engage with a carrier or brick, for the purpose of lifting the same to the desired height, and

then if desired to tilt some of the brick in one.

'sclosed invention direction and some in an opposite direction, e1ther by the arm or a separate hoist, into brick carrying trucks, for example; thereby providmg a power machine wh1ch will tend to facilit and economy. of operation, particularly 1n a brick yard.

These being among the objects of the present invention, the same will now be described with reference to the accom anying drawings showing preferred embodiments of the invention, wherein I Figure 1 is a side elevation of the im roved machine provided with a full-circle swinging crane;

vator or liftin means, havin wheels 16 running on rails 1 of the uprig ts 14. i The u rig ts 14 are also firmly fixedto and y form a part of the superstructure or main fraine13.

. As distinguished from the invention of my prior application above mentioned, the carriage 15 supports a rugged arm 18 which in usm position-extends fromthe lowerend of t ecarriage rearwardly of the machine. This arm 18 is of strong construction and of suitable length, being specially designed and adapted to engage with a brick or other carrier, close to t e ound or somewhat into it, and lift the carr1er;with facilit maybe compared with the bla e' of a semaphore signal in that it is sleeved onto pivot 19 ournaled in brackets 20, which are rigid with the lower end of the carriage, the pivot being at ri ht angles to the arm, so that the arm may swung down to project rearwardly from the machine in a substantially horizontal direction as shown in Figs. land 5, and be swung up to the position shown in Fig. 4 when not in use.

The rearwardly projecting arm 18 is provided with a heel 21 which extends below the carriage and inwardly of the pivot 19 when the arm is in using osition, the carriage being provided with a rigid, horizontal, crossbar 22 which supports a roller 23 guided by a fixed upri ht rail 24 which is located intermediately o? the rails 17 and is parallel therewith. Adjustable in the cross-bar 22 is a vertical screw-spindle 25 provided at its upper end with a crank handle 26 for turnin it and adjusting it so as to set the lower en of the screw spindle 25 in such position relatively to the arm 18 that it will form a stop or abutment, inwardly of the pivot 19, for the heel 21 of the arm when the arm is in substantially horizontal position. Or, the arm may thereby be set to a somewhat inclined posltion, as occasion may require. When the arm is in use the thrust of the weight carried by it will be taken by theimpingement of the heel 21 on the stop furnished by the lower end of the screw 25, and these 'arts should therefore be of strong and dura 1e construction.

' In Figs. 3 and 5 spaces are left between the sleeves of the arm and the brackets v20,

which permit of the arm being shifted and adjusted laterally, more or less. At the top of the carriage is-a roller 27 This arm which also travels on the rail 24, and there is i also at-the front of the carriage a suitable preferably as disclosed in my said previous ap lication, the crane havin a boom 32 and being provided with a hoistmg cable 33 carrying a block 34 provided with a hook 35, the cable being operated in any suitable man-' ner as from a hoisting drum on the crane. The lifting arm 18 or the book 35 of block 34 are adapted 'to connect with a suitable article or material carrier 36, as for bricks, for example, this carrier being designed Ereferably to support as many as a thousand ricks. The carrier comprises a platform 37 and a top portion or saddle 38, the arm 18 being adapted to engage within the saddle, and the hook 35 to engage a chain 39 which is passed through suitable-holes in the saddle 38. The boom 32 supports a sustaining line or carrier leveling cable 40, which keeps the articles from being dumped, except when desired, that is when the article carrier is operated from the crane 31.

Shouldit be desired to dump the brick which are at the oflside of the carrier, away from the cable 40, the block 34 is lowered, and this effects an inclination of the vcarrier from the point of support provided by cable 40, and the dumping of those brick, the

other brick between the saddle and the said the hook, so as to dischargeall of the brick on' the carrier at one time.

Referring to Fig. 6, there is shown a modification of the machine, which omits the crane. In this modification a hoisting drum 41 is mounted on the truck, and is for the operation of a cable 42 and is trained over a sheave 43' of the lifting means, such as shown in Figs. 3, 4 and 5. This cable 42 is also trained over

sheaves

44, 45 so that by the use of the hoisting drum 41 the lifting means may be operated. Connected with the cable 42 is a yielding connection 46 so that the cable may be run more smoothly. In Fig. 6 the bracket 47 of the carriage is shown together with the lifting arm '48, which is mounted on the bracket 47 by means of a pivot 49. The article carrier 50 is shown supported on the arm 48 carrying a load of brick.

Referring to Figs. 7, 8 and 9, there is shown a modified construction of lifting arm 51 and heel portion 52 thereof. The heel portion 52 naeaeae 'of'the arm has a hole 53' for ,the pivot. support for the arm, which arm may beitilte sidewise with respect to the heel portion. In both forms of lifting arm, thatis the arm 18 of Fig. 1 and the arm 51, the same is formed in the nature of. an elongated heavy blade, set edge uppermost, that is to say the arm tapers transverse] its thickerportion being at the bottom and its thinner or edge portion at the top. The outer portion of the arm has its lower edge 54 inclined, so that the end of the arm is formedmore or less as a taper ng toe, to more readily engage with the article carrier, especially if the arm has to dig somewhat into the V ound. In Fig. 1 the arm 1s somewhat simi arly formed, although the inclination is less abrupt.

A rigid shaft or core 55 extends from the heel portion 52 of the arm, as clearly shown in Fig. 7, and the arm 51 is provided with a longitudinal bore which receives the rigid shaft 55, so that by suitable means the arm 51 may be transversely tilted in one direction or the other with respect to heel portion 52 as indicated by dotted lines in Fig. 8. The outer end of the shaft 55 extends into a recess 56 formed in the outer end of the arm51. said reces forming a housing for a toothed ear 57 which is fixed rigidly on the shaft 55.

here is a pinion 58, the teeth of which ar'e in constant mesh with those of the gear 57, and which is fixed'on a small shaft 59 supported in a suitable bearing and that may be turned by means of a removable hand crank 60. A lug 61, Fig.9, projects from the arm, into the recess 56, in the region of the pinion 58, so that it may be caused to be engaged by the teeth of the pinion, when the pinion is shifted by an expansionlspring 62, the tendency of which is to urge the pinion 58 outwardly and to cause the teeth thereof to engage with and belocked by the lug 61. The pinion 58 cannot be rotated while it is locked by the lug 61, and hence the arm 51 is locked against a tilting movement upon the shaft 55. However, when it is desired to tilt the arm the crank 60' is engaged'with the shaft 59 and the pinion pushed inwardly soas to depress the spring 62 until the pinion'disengages from the lug 61, whereupon the pinion may be turned by the hand crank,-.its teeth meshing with the'teeth of the gear 57, causing a travel of the pinion in an are around the gear 57, thus causing the arm 51 to'tilt laterally. It is obvious that such lateral tilting of the arm with respect to its heel portion 52 will result in a tilting of the article carrier engaged by the arm, so that the material supported by the carrier may be dumped to either side of the arm.

The article carrier has been briefly referred to, but not described in detail. In Figs. 10, 11 and 12 the preferred construction of article carrier is illustrated. It comprises spaced metal slats or bars 63 which with side bars (11 the artic peer to the taper of the liftin 64of angle meta form the platform 3710f I e carrier. The vertical-flanges of] the angle bars 64 are provided with .holes 65 with which the ends of the slats 63 are engaged, the horizontal flanges of the angle bars being1 in engagement with the lower edges of t e slats 63. These parts may be rigidly connected in any suitable manner as is obvlous. The saddle or top portion 38 of the article carrier is preferably constructed of metallic side plates 66 which diverge 'toward their lower edges in the form of an inverted V, and through holes 67 in these plates 66 there pass the slats 63, so that a firm and rigid connection of the saddle with the slats is provided, especially when bottom flanges 68 of the saddleare engaged with the under edges of the slats 63 and welded or other-v wise secured thereto. The saddle plates 66 converge and their upper portions form webs 69 between which there is received a metal filler strip 70, which may be firml attached to the saddle plates as by rivets 71 passing through the filler strip 7 O and the web portions 69. Holes 72 are formed in the upper portion of the saddle so as to provide for the reception of chains or'the like, whereby the article carrier may be lifted from the top thereof, as by means of the

block

34, 35 of Fig. 1.

The saddle 38 is'hollow and provides a recess 73 in'the middle of the carrier, and which transversely is complementary'in taarm, which when in proper position may e moved longgtudinally into the lower part of the recess the arm 18 will first be raised to snugly and firmly-engage with" theup er portion of the saddle, and then to lift t e brick or other material which may be supported upon the platform 37 0f the carrier. 7

Figs. 13 and 14 illustrate a modification of the article carrier, in which. the metallic side plates 74 of the saddle are provided with bottom flanges75 beneath which is a bottom plate 76, which with the bottom flanges 75 are, by means of bolts 77, rigidly,

held to the opposite edges of metallic slats 78 which pass between the flanges 75 and plates 76. These slats 78 run parallel and are-separated 'by means of strips 79 of corrugated metal, to form a grating and for strengthening the construction, the ends of the slats and strips being rigidly secured to angle sidebars 80 which form opposite side ed es of the platform of the carrier.

still further modification of the article carrier is illustrated in Figs. 15 and 16, wherein the bottom flanges 81 of the saddle are welded or otherwise rigidly secured to adjacent inner portions of

metallicplatform plates

82, 83, one of which extends away from one side of the saddleand the other of which extends away from the other side and then as'the lifting means is operated of the saddle. The

platform plates

82, 83 are formed with integral upturned flanges 84. which are welded or otherwise secured tothe inner faces of the saddle side lates. To re- 5 inforce and strengthen the

p atform plates

82, 83 metal angle bars 85 are welded or otherwise secured transversely to the under sides thereof, extending from the extreme edge of one platform plate to the extreme 19 edge of the other platform plate. Furthermore the outer edges of the-platform plates may be turned up as at 86 in order to more reliably hold the articles to be placed upon the platform.

It is obvious that under the present invention, a number of lifting arms instead: of one arm may be employed, and that when more than one is used, not only may bIlCk be raised or lowered'bodily, 'but stone, etc.,

and without requiring the use of a special.

carrier.
