MACHENE FOR SIZING TILES.

Application filed January 5, 1605.

To ZZ ywho/m t may concern .Be it known that I, GEORGE A. STANBERY, a citizen ogt' the `United States, residing at Zanesville, in the county or" Muskingum and State of Ohio, have invented certain new and useful Improvements in Machines tor Sizing Tiles, of which the following is a specification.

My invention relates to machines for ascertaining the sizes of tiles, in order that they may be assorted accurately and quickly according to their sizes.

In the manufacture of tiles of any size, say of six inches in length, it is found that they vary in length after leaving the kiln, some ot them being a fraction of an inch shorter, while others are larger in fractions oi an inch, than the standard gage. It is customary to assort tiles which vary a l thirty-second of an inch, more or less from,

the standard gage into different groups or piles; and said tiles are distinguished in the trade by appropriate characters or designations, according to their variations from the standard gage.

'.lhe machine 0f the present invention may be operated easily and quickly for the purpose of accurately ascertainingr the grade according to size, or the length, of the tiles, and to enable the attendant to assort all the tiles or the different graduations of sizes of tiles into separate groups or piles.

lily machine. also, makes provision 'for the measurement of tiles oie ditferentlengths, sav from one or more inches up 'to eight, ten or more inches, each of the standard lengths or tiles, and the graduated tiles of such standard lengths, being measured and assorted accurately according to the classes thereof. Y

The machine is constructed to compensate for wear in it-s several working parts, thus insuring accuracy in the performance of its work.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope ot they invention will be defined by the anneXed claims.

Reference is to be had to the accompanying drawings, forming a part of this speciication, wherein like characters of reference are used to indicate corresponding parts in all the iigures.

chine for sizing tiles, constructed in accordance with my invention. F ig. 2 is a view in side elevation, illustrating the employment of means for accurately positioning an adjustable but normally stationary member, the latter being adapted to copera-te with a movable member in determining the length of a tile. Fig. 3 is a plan view, omitting the casing or housing and showing several working parts of the machine. Fig. et is a detail view inend elevation, partly broken away and in section, showing the application of the adjusting device to the bed plate. Fig. 5 is a` View partly in section, and partlv in side elevation, looking toward the indicator device and the movable member, that is adapted to cooperate with the relatively fixed member. Fig. 6 is a longitudinal sectional elevation taken in the plane indicated by the dotted line 6 6 of Fig. 3, and Fig. 7 is a vertical transverse section on the line 7 7 of Fig. 3.

The base A of the machine is shown by the drawings as being` substantially l.- shaped, but it will be understood that the shape is immaterial and may be modiiied or changed at pleasure. One arm of the base is provided with a longitudinal guideway a, which may be either dovetailed or T-shaped in cross section, as shown by Fig. 4, and on the opposite sides of this guideway are provided the wear plates Z9, the latter being fastened removably to the base by any suitable means, such for example as the` screwsfb.

My machine includes in its construction two cooperating members B, C, between which the tile is adapted to be placed in the operation of gaging the same, the member B being a relatively stationary part, although it is capable of adjustment on the base, while the member C is a movable part which is shifted at will away from the member B.

As herein shown, the member B is in the form of a head having a dovetailed or T- shaped shank, arranged to lit snugly in the able screws b4. It is evident that the screws may be removed and the Wear plate b3 reversed in position on the head, or this Wear plate may be replaced by another plate when it is Worn. In alike manner the plates Z) may be removed from the base A and yreversed in position thereon, or said plates may be throvvn aside and others substituted therefor, thus making provision for taking up the Wear in some of the parts of the machine.

The movable member C is represented in the form of a plunger adapted normally for slidable movement toward and from the member B. Said plunger C is shown as of cylindrical form, but it will be understood that a square or polygonal plunger may be used, hence I do not desire to coniine myself to said cylindrical form lof plunger. Said member C is supported in a boxing Vor housing D, Which is secured in a suitable Way to the bed A. The boxing is provided with a longitudinal chamber in Which the plunger C is snugly fitted, and said boxing is provided in o-ne side With a notch or recess d, the purpose of which Will presently appear. The plunger is provided at its respective ends vvith collars c, c, adapted to limit the endwise movement of the plunger in the boxing, and at its Working end said plunger has a gage pin o2, Which is clamped removably to the plunger by a set screw c3. rlhe plunger is drawn or impelled normally in one direction by a spring E, Fig. 5, which is arranged Within a chamber e, in the under side of the bed A, one end of said spring being anchored in place in a suitable Way. The other end of the spring is attached to an arm e', which is made in one piece with the collar c', thus connecting the spring with the rear end of the plunger, said arm e being arranged to Work in a slot e2, which is provided in the bed A, see Fig. 3.

The plunger is adapted to be dravvnback or retracted at Will by the employment of a suitable operating device, Which is herein shown as a lever F, the latter being arranged in the chamber e, and projecting at its respective ends through slots in the chambered part of the bed plate, one of said slots being indicated at 7, in Figs. l and 2. One end of the lever is fulcrumed on a short post that depends from a bracket plate f, secured to a side portion of the bed, While the free end of the lever extends beyond that side of the machine on which the operator is stationed, thus placing the lever Within convenient reach of the operator. The arm e of the plunger is arranged in the path of the lever F vvhen it is moved in one direction, but this lever may be moved freely in an opposite direction Without engaging with said arm e', whereby the lever When moved to the right Will Withdraw the plunger C away from the member .B, but the movement of the lever F toward the left Will not affect said plunger, thus permitting the spring E to act on said plunger in moving it toward the head B. It Will be understood, therefore, that the spring E and the lever F operate independently on the plunger to control the same, the spring E moving the plunger in one direction, While the lever F operates to move the plunger in an opposite direction. This construction and arrangement of parts not only provides for holding the plunger normally in position and for the convenient Withdrawal of the plunger Whenever desired, but it prevents an attendant from pressing on the plunger so as to :torce it up into engagement with a tile, it being understood that the lever cannot so act on the plunger as to move it toward the Work placed between the head B and the pin c2 of the plunger.

The plunger C is provided with a plurality of teeth g, which form a rack, the latter being exposed through the open side, d, of the boxing D. When a plungerI of cylindrical form is used, thel teeth g are circular and extend entirely around the plunger or rack C, but it is evident that a polygonal sided plunger may be used, in Which case the rack teeth may be formed on one face of the plunger'. I prefer,fhovvever, to employ the cylindrical. plunger having the-circular rack teeth, because the plunger 'can be turned axially by hand, to present other surfaces of the rack teeth in position for engagement by a toothed segment H,

thus enabling the parts to be adjusted in a Way to compensate for Wear.

It should be understood that, in the use of the machine, the plunger or rack C has a sliding movement normally in the boxing or housing; such sliding movement being imparted thereto in one direction by the lspring E, and the lever F being used to move the plunger at will in the other direction. Under this mode of using Ythe machine, the indicator mechanism, except the Vpointer and thedial, are concealedr by a casing, L, but this casing mayberemoved from the bed A,'so that an attendant can gain access to the plunger C, for the purpose of adjusting' it, as by turning it axially by hand, to bring fresh surfaces of the rack teeth g into engagement vvith the toothed segment H.

r1`he segment H is mounted loosely on a iixed post I, and around this post is vcoiled a torsion spring, I', one end of Which is anchored on the post, While the other end oi said spring is connected with the segment, for the purpose of normally turning it toward the right or holding one tooth of the segment normally in engagement With one face of a tooth g on the rack. This construction and arrangement takes up the slack between the teeth of the segment and able characters designating the sizes of the tiles, as for example, the spaces on the left of the standard gage line S, have the characters A, L, XL, while the spaceson the right of said gage line are inscribed with the characters B, C, D, S and XS. The iirst mentioned group of three spaces indicate the tiles that are larger in specified degrees or graduations, than the standard size, while the last mentioned group 0f live spaces indicate speciied graduations of under sized tiles. The dial herein shown is graduated to indicate variations of a thirty second of an inch in tiles, the lengths of which may slightly exceed, or be less than, the true size; yet the particular graduation of the dial, and the scale of measurement secured by said dial and the machine as an entirety may be modified and changed within` wide limits. It should be understood, therefore, that the dial may be marked to indicate as many oras few graduations of any and all sizes of tiles which it is desirable to measure; that the characters or designations employed on the dial may be changed' at pleasure, and that the dial may be graduated to measure variations in sixteenths of an inch, or sixty-fourths of an inch, or in fact any fractional part of standard measurement. The dial is shown as secured to the bed A, but it is evident that a dial graduated according to one scale may be replaced by other dials graduated to different scales.

rlhe several Working parts comprising the indicator mechanism, and certain parts `of the plunger are inclosed within a casing L, the same being secured removably on the bed plate, said casing having an observation slot mi, through which the dial K is exposed.

For the purpose of accurately adjusting the head or member B, I have provided an auxiliary adjusting contrivance which is adapted to be fitted removably to the bed A, in a position to coperate with the head B. This device is shown by Figs. 2 and 4 of the drawings, and it consists of a post N, having a foot piece, arranged to work in the guide-way of the base. On the post is itted a slidable member N, and said post has a threaded stem a, on which is screwed a clamping nut a, the latter being adapted to press the member N', upon thebed for the purpose of clamping the adjusting devices detachably in place. The post N carries an adjusting screw O, which is adapted to engage with the head B, for the purpose of giving a minute accurate adjustment to the latter.

The operation of my invention may be described as follows: A gage Z of the standard size of any tile is employed preliminarily for adjusting the cooperating members B, C, accurately to their working positions. The head B is moved on the bed to its approximate position, and the gage Z is placed on the bed between said head and the pin c2 of the member C, see F ig. l. The auxiliary adjusting device is now placed in position and tightened by the nut n', after which the screw O is adjusted for the purpose of moving the head B, the gage Z, the plunger C, and the pointer, until the latter moves to B on the dial in order to secure an exact working position of the parts. After this operation, the head B is clamped tightly in place by the screw b2, the auxiliary adjusting device is detached, and the gage block Z is removed, thus placing the machine in condition for use. The operator may now move the lever F to the right, so as to withdraw the plunger and increase the space between the pin 02 and the head B. A tile may now be dropped in place on the bed between said head and the pin, and by releasing the lever the spring E moves the plunger until the pin c2 engages with the tile, whereby the adjustment of the plunger gages the pointer so as to indicate on the dial the size of the tile. rihe lever is now operated and the tile removed and placed in a group or pile of the de termined size. These operations are repeated with eachtile and the different sizes of tiles may be quickly and rapidly assorted. To change the gage of the machine for use on tiles of another size, the screw 722 is released, and the head B adjusted lengthwise on the base A, the auxiliary adjusting device and the gage block Z of the required size being employed to accurately determine the position of the head B. lt is evident that tiles of any size within the capacity of the machine may be quickly and accurately gaged by proper adjustment of the member B with relation to the member C, and tiles of any length may be assorted according to their grade by the use of the machine in the manner heretofore described.

From the foregoing description it will be seen that I have produced a simple, efiicient and accurate machine which may be used in ascertaining` the variations or graduations in length of tiles belonging to a given size; and that the machine, by the simple adjustment of the head or member B, can be adapted for use in connection with any llO other different size of tile to ascertain vthe variations or graduations of tiles forming sub-divisions of the main group or class.

Although I have shown and described my machine as being especially adapted for the measurement and graduation of tiles, it should be understood that the machine can be used to advantage in the Work of measuring other articles and grading them according to their sizes.

Changes in the form, size, proportion, and minor details inconstruction may be made Without departing from the spirit of the invention or sacrificing any of the advantages thereof, and I, therefore, reserve the right to make such alterations and modifications as fairly fall Within the scope `of my invention as defined yby the annexed claims,
