BRICK-EDGING MACHINE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed March 25,1905- Sellal N0- 251,935.

Be it known that I, FRANK ELviN PIPER, a subject of the King of Great Britain, residing at Red Deer, district of Alberta, North-West Territories,Canada, haveinvented certain new and useful Improvements in Brick-Edging Machines; and I do hereby declare that the following' is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful machines adapted to be used in edging bricks; and it consists in certain features of novelty in the construction and operation thereof, all as hereinafter more fully described, and specifically pointed out in the claims.

The object of the invention is to provide a machine for the purpose stated which will bc practically automatic in its operation and which is so constructed that bricks may be deposited upon pallets in a swinging palletframe, said bricks being deposited upon their sides, and by means of the mechanism hereinafter describedsaid bricks are automatically deposited upon their edges upon a table provided for thatpurpose.

The machine comprises in its operative parts a movable pallet-frame pivotally mounted on a fixed-frame, so as to be capable of both lateral andvertical movement upon relatively.

. ism hereinafter'referred to.

fixed pivots, and includes in its construction adjusting means whereby the machine is placed in operation in such relation to the adjustable driving mechanism that greater or less speed of operation may result, according to the requirements.

The-machine also comprises other features of novelty relating to the construction and operation thereof, all as hereinafter more fully described. 'Y

Referring to the annexed drawings, in which similar numerals of reference indicate corresponding parts in all the views, Figure 1 is a plan view of the machine. Fig. 2 is a side elevational view thereof. Fig. 3 is a front elevational view. Fig. 4 is a fragmentary side elevational view looking toward the side opposite' that shown in Fig. 2. Fig. 5 is a sectional view illustrating the clutch mechan- Fig. 6 is a detail of'a portion of said clutch mechanism, `being approximately a sectional view on line 6 iof-Fig. 5. Fig. 7 is a longitudinal sectional view taken on line 7 7 of Fig. 1 look- Fig. 8 is a view showing a portion of the supporting-frame with the pallet-frame and its immediate connections shown in different positions for the purpose of better illustrating the operation of the machine. Fig. 9 is a sectional view taken on line 9 9 of Fig. 1 looking in the direction indicated by the arrow.

Referring to the parts, 1 is a relatively fixed frame hereinafter referred to as a supporting-frame, upon which the operative mechanism is carried. ing-frame 1 are vertically-disposed brackets 2, which are pivotally connected with said supporting-frame, and said brackets are provided with the cam-shaped slots 3, which are disposed approximately in the arc of a circle struck from the center of the transverselyextending shaft 4, upon which the pallet-frame hereinafter described is supported. The brackets 2 serve as supporting means for said shaft 4, and bearings 5 6 on said supportingframe 1 and connected with said fixed frame 1 and with said brackets 2 serve as means for pivotally mounting the pallet-frame on the shaft 7, the pallet-frame being so mounted as to permit it to be tilted laterally, as shown by the dotted lines in Fig. 3, for loading and also capable of swinging movement, as shown in Fig. 8, for the purpose hereinafter described. Said brackets 2 are formed as flanges rising vertically from the bed-plate 2, with which said bearing 6 is connected.

The pallet-frame 8 is slotted longitudinally, as shown, said slots 8 serving as bearings for the crank-pins 9, by means of which the position of the slidable pallets 10 are regulated, while the crank-pins 92L serve as means for rocking the relatively fixed pallet lO. Extending longitudinally of the pallet-frame is the link 11, which is connected, by means of the bell-cranks 12, with the longitudinallyslotted link 13, and the crank-pins 9 9, which serve as pintles for the said pallets 10 10, enter the slots 14L of said link 13 and are guided thereby. Connecting the link 11 with the bell-crank lever 14 is a link or rod 15, whereby movement of the links 11 and 13 are controlled by said bell-crank lever 14, which latter is pivoted at 15a inthe pallet-frame 8 Rising from the support- A IOO and is provided with the pin 16,.adapted to travel in said cam-shaped groove 3 in the bracket 2. Thus when said pallet-frame is IIO the bell-crank levers 12, pivotally connected to the link 13, the crank-pins 9 9u of the pallets 10 10L are rocked, so that, regardless of the elevation of the free end of the palletframe, said pallets are always held with their bottoms in a horizontal position until said pallet-frame reaches its maximum elevation, as shown by the central dotted portion of Fig. 8, after which the continued movement of said pallet-frame and the appui-tenant connections described turns said pallets to the position shown in dotted lines at the left of Fig. 8, wherein the bottom plates thereof are turned to a vertical position, thereby placing the bricks upon their edges, it being understood that the bricks are placed upon their flat sides in the first instance, and through the turning of the pallets the bricks are carried to a position where they will rest upon their longitudinal edges. Coperating with the pallet-frame and said pallets is a yoke 18, which is pivotally supported upon the shaft 19, so as to be rockable thereupon, and extending frorn said yoke 18 are three arms 20, 21, and 22, through which extend the pintles 9b of the slidable pallet-frames 10.

In Fig. 7, counting from the bracket 2, it will be noted that the second pallet-frame 10 is carried on a pintle 9c and said pallet, though rockable on said pintle, is not slidable in the pallet-frame.

By reason of the eccentric relation of the pintle connection of the arms 20, 21, and 22 to the shaft 19 it will be observed that as the vpallet-frame is carried upwardly said arms will act as follows: The arm 2O will carry the pallet connected therewith in a direction toward the free end of the pallet-frame, while the arms 21 and 22 will carry the pallet located near the free end of said pallet-frame toward the pallet 10, held centrally thereof, thereby bringing said pallets nearer together and causing the bricks to be deposited more closely together than would otherwise result.

Cooperating' with the pallet-frame described is a table 24, which is carried by the frame 25 and is removably mounted upon said frame,

the frame having the laterally-extending arms 26 for supporting the table. The'frame 25 is mounted upon the rockable shaft 27, held in the bearing 28, extending from the frame 1. Integral with the frame 25 is an extension 29, extending beyond said shaft 27, and pivotally connected withsaid extension 29 is a link 30, which link is pivotally connected at its opposite end with the link 31, which in turn is rigidly connected to and mounted upon the transverselyextending stub-shaft 32, held in suitable bearings on the frame 1. Rigidly connected with said stubshaft 32 and extendingdownwardly therefrom is a second link 33, which is provided at its lower end with a pin or roller 34, adapted to travel in the cam groove or channel 35 in the cam-wheel 36, so that at the proper time the links 31 33 and stub-shaft 32, through the medium of said cam 36 and the connectinglink 30, will rock the frame 25 for the purpose hereinafter referred to. Mounted on said shaft 27 is a segment 37, which is rigidly connected therewith, and meshing with the segment 37 is a segment 38, carried by the segment-frame 39, which segment-frame is mounted upon the stub-shaft 40, as best shown in Fig. 2. Connecting the cam 36 with the segment-frame 39 is a pitman 41.

Rigidly connected with the shaft 27 is a crank-arm 42, having the laterally-extending cranked portion 43 and inner longitudinallyextending portion 44, as best shown in the plan View, Fig. 1. A bearing 45 is provided, as best shown in Fig. 7, for the crank-arm 42 44, said bearing being connected with the downwardly extending portion 46 of the pallet-frame 8, and it will be evident that when the shaft 27 is rocked in the proper direction said pallet-frame will be raised by means of the crank-arm 42 44.

The cam 36 before referred to is carried upon the shaft 48, which shaft has mounted thereupon the driving mechanism hereinafter described, and the shaft 48 through said driving mechanism is driven from the power-` shaft 49.

In a machine of this character it is desirable that its operation shall be as nearly as possible automatic, and to that end there is provided an adjustable time-regulator which may be adjusted so that the driving mechanism will become effective toraise the pallet-frame and its appurtenant connections' either very quickly after the bricks have been deposited upon the pallets or after the lapse of a short period of time, as may be desired, and to that end means are provided as follows: Referring to Figs. 5 and 6,it will be noted thatthere ismounted upon the cam-shaft 48 a gear-wheel 50, having external and internal teeth 51 yand 52, said wheel 50 being loosely mounted upon said shaft 48. In convenient juxtaposition to the wheel 50 is a band-*wheel 53, having any desired number of spokes, though shown in Fig. 6 as provided with three spokes 54, the said wheel 53 being held by means of the key 55 rigid to the shaft 48, so as to be rotatable therewith. Next beyond the wheel 53 is a sleeve 56, which is also loosely mounted upon the shaft 48. Slidable longitudinally of the sleeve 56 is a collar 57, having a circumferential groove or channel 58 therein, in which is mounted the yoke 59. (Shown in Figs. 3 and Extending from the sleeve 56 and rotatable therewith is a ratchetframe 60, having the ratchet-teeth 61 formed in the cam-shaped rack or segment 62 thereof. Mounted in the member is a radiallyslidable pin 63, which is connected with the pawl-arm 64, which pawl -arm or pawl is adapted to engage with the inner teeth 52 of the wheel 50, as hereinafter described. Connecting the .collar 57 vwith the pawl-arm. 64 is IOO IIC

a link 65, which is pivotally connected to said collar and said pawl and is so arranged that when the collar 57 is carried in a direction away from the wheel 5() the pawl 64 will be carried away from the teeth 52 of said wheel 50 and disengage therefrom; but when it is desired to start the machine in operation the collar 57 is carried in a direction toward the wheel 50, whereupon the pawl 64 will engage the inner teeth 52, thereby causing the sleeve 56 -to rotate with the wheel 50 until the pawl 64 comes into contact with one of the spokes 54 of the band-wheel 53, whereupon the shaft 48, carrying the cam 36, will be rotated, and for leach complete rotation of said cam 36 the pallet-frame will be lifted from the position shown in Fig. 2 to the position shown in dotted lines at the left of Fig. l8, thereby turning the bricks which may have been placed upon the pallets from their flat sides to their edges. It will be understood that the driving-shaft 49 carries the driving-pulley l7() and the pinion 71, which meshes with the teeth 51 of the gear-wheel 50, and the gear-wheel 50 is in constant rotation .while themachine is in service, depending upon the clutch mechanism disclosed in Figs. 5 and 6 to operate the cam-shaft 48, which then becomes the actuating-shaft of the machine. The cam-shaped segmental rack 62 is loosely mounted upon the sleeve 56 and, as will be noted in Fig. 4, cooperates with the pawl 7 2, Vwhich pawl serves to normally sustainV said rack in any desired position. The pawl 72 is provided with the counterbalancedextension 73, beyond the pivot 74 thereof, and said counterbalance is adapted to rest upon theeX- tension 75 of the arm 76. Perforations are provided in the segment 77, and by means of a pin 78 the arm 75 76 may be swung upon its pivot in the bracket 79, so that the portion 75 may raise and lower the counterbalance portion of the pawl 72, and as the segmental rack 62 is eccentrically journaled upon the shaft 48 it is evident that the'normal position of said segmental rack is determined by said pawl 7 2. Thus if it is desired tostart the operation of the machinequickly upon turning the pallet-frame from the. dotted position shown in Fig. 3' to the full position then the rack 72 is placed so that the pawl 64 will be near to one of the spokes 54; but if a longer period of time is required the pawl 72 and said rack 61 are so adjusted that the pawl 64 will rest normally at a position farther away from said spoke 54, and a longer time will be required for said pawl 64 to contact with the contiguous spoke 54 of the wheel 53.

Mounted upon the wheel 53 is a pawl 80, influenced by the spring 81 to engage the pawl 64, so that when the parts are engaged, as just described, the segmental rack 62 cannot become accidentally disengaged and fall back by gravity after the teeth thereof have passed beyond range of the pawl 7 2.

Cooperating with the clutch mechanism just described isa lever 83, which is mounted upon and rigidly connected with the shaft 84,y to which is rigidly connected the yoke 59 before referred to. Held within the bifurcated end 85 of the lever 83 is a pin 86, projecting laterally from the rockable member 87, which is carried upon the shaft 7,so that as the pallet-frame. is rocked laterally upon said shaft 7 the members 59,83, and 87 will be thrown as follows: Vhen said pallet-frame is thrown laterally to the positionindicated by the dotted lines in Fig. 3,the yoke 59 will carry the collar 57 away from the wheel 53, thereby disengaging the pawl 64 from the teeth 52 of the gear-wheel 50; but when the pallet-frame is thrown to the position shown in full lines in said Fig. 3 and as shown in Fig. 1 in the plan view the members 59, 83, and 87 will be thrown to the position indicated in full lines in Fig. 3, thereby shifting the collar 57 nearer to the gearwheel 50, thereby causing the pawl 64 to engage with the inner teeth thereof, with the result heretofore described.

In addition to the clutch mechanism hereinbefore described the driving-pulley is provided with a clutch 70, controlled by means of the rod 70h and lever 70, so that, if desired, said pulley 70 may rotate idly upon its shaft.

Instead of the band-wheel 53 a single spoke, as 54, may extend from a hub keyed on the shaft 48 with the same result in operation.

In a machine which has been built the sleeve 56 and collar 57 are formed of a single casting, which slides longitudinally of the'shaft 48, carrying a pawl corresponding to the pawl 64 into engagement with teeth on the sideof the wheel 50, and it will be evident that such construction may be substituted for that shown in Fig. 5 in some cases with beneficial results.

A weighted arm (not shown) may be used to balance the parts 24, 25, and 26, if desired, and it is evident that weights may be substituted for the spring 30Cl with good results.

It is to be noted that when the pallet-frame is tilted to the position shown in dotted lines in Fig. 3 the bricks may be emptied from the mold onto the pallets 10 and 10 on their fiat sides in the first instance, thus giving the operator ample time to deposit the bricks before the pallet-frame is righted and lifted as described.

On the arms 26 are Xed clips 26*L and rockable clips 26h, the latter of which are provided with the springs 26C, adapted to normally hold them in engagement with the table`24; but when the pallet-frame occupies the position shown in dotted lines at the left of Fig. 8 the rockable clips strike the arm 25a, thereby releasing the table 24, so that it may be removed.

It will be evident from the foregoing that bricks may be deposited on the pallets from the molds, the bricks resting upon their Hat faces, after which the pallet-frame may be rocked to the position shown in Fig. l, where- IOO IIO

upon if power is applied to the shaft 49 the machine will automatically turn said bricks and deposit them on their longitudinal edges upon the removable table 24, which may be then removed from the frame 25 26 and carried to the yard or kilns for drying.

Extending from the bearing 28 to the crankarm comprising` the members 31, 32, and 33 is a tension-spring 30, which tends to hold the pin or roller 34 in the cam-groove 35.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
