BURNlSHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 892,944, dated November 13, 1888.

Application filed March 14,1888. Serial No. 267,148. (No model.)

To aZZ whom it may concern.-

Be it known that I, CALEB JOSHUA BLAKELY, of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Boot and Shoe Burnishing and Polishing Machines; and I do hereby declare the following to be 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.

My invention relates to an improvement in boot and shoe burnishing and polishing machines.

The nature and object of my present invention consists in the provision of two sets of burnishing apparatus mounted on one machine and driven by one shaft, so connected thereto that they will be independent in action with regard to each other, and be permitted to re ciprocate and describe arcs of different lengths to conduct different burnishing operations on opposite sides of the same machine.

A further object is to so construct a shoe and boot burnishing machine that it will be bal anced in movement and prevented from jar or objectionable vibration in its moving parts.

A further object is to provide a lamp-stand and lamps which may be used to heat the bur nishing-tools while they are in position for use.

A further object is to furnish the rotary shaft which drives the burnishing mechanism with brushes that may be employed to polish the burnished work and be in convenient position for such a purpose.

XVith these objects in view my invention consists in the construction of parts and their combination, in a manner that will be hereinafter described, and indicated in the claims.

Referring to the drawings making a part of this specification, Figure 1 is a front elevation of the machine in position for use. Fig. 2 is a rear elevation of the burnishing-machine complete. Fig. 3 is a plan view of the device. Fig. etis a cross-section in elevation ofthe machine taken on the line at m, Fig. 3,to show the means of reciprocating the burnishers. Figs.

5 and 6 represent enlarged detail views of one of the rock-arms which carry the reciprocating burnishers supporting-arms. Figs. 7, 8,

9, and 10 are enlarged detail views of one rockarm, eccentric, and pitman, which drive the burnisher-tool.

For convenience in use the operating mechanism of this burnishing and polishing machine is supported upon avertical hollow column, A, of proper height, which is provided with a wide base, A to afford stability, the upwardly-tapering column being cut away on opposite sides at A to lighten it, and also to permit a belt, which engages a driving bandwheel, a, to have contact with another pulley on the main shaft of the machine, which will be fully described in its proper connection with other parts of the mechanism.

Within the column A, opposite the openings A, the fast and loose pulleys a are supported on a horizontal drive-shaft, A*, which also supports and rotates the band-wheel a when the fast pulley a is speeded by a belt (notshown) which transmits motion and power from a proper source. The upper end of the column A is extended laterally on each side to produce a base-plate, A, on which the machinery is placed,which will now be described. Two vertical bracket-stands, b b, are erected on the base-plate A,which are of equal height and the same general form. These are pro vided with adjustable boxes 0 0 on their upper ends to revolubly support the spindle B horizontally. The spindle B, just mentioned. gives support to a pulley, of, which is secured thereon near its center of length or in the same vertical plane with the band-wheel a, and thus permits the belt 1 to travel properly on the faces of the wheel and pulley.

A balance-wheel, o, with a heavy rim is mounted upon the spindle B, near to the pul ley a It, by momentum afforded, gives a smooth movement to reciprocating devices, which will be explained, and prevents objectionable wearing motion or vibration of the whole machine when the burnishing-toois are in rapid mot-ion.

Upon the base-plate A, near its front edge,

there is an elongated cylindrical hub, B,formed 1 or secured to the plate. This hub is axially perforated for the reception of a round bar, I, which is made-to fit the bore of the hub, and is secured in place Within it by set-screws or 6,) which slots afford means for the adjustable attachment thereto of the pitmen G, one of which is shown in position in Fig. 1, and both as they are connected to the arms and the drivingeccentrics H in Fig. 3.

The eccentrics H are secured on the spindle B, near the outer ends of the same, so as to cause the looselyattached pitmen G to lie parallel to the sides of the rock-arms F, to

which they are fastened by means which will be hereinafter explained. The method of connecting these parts is shown in the enlarged detail views given in Figs. 9 and 10.

In Fig. 10, which is a top plan view of one of the rock-arms G and an attached pitman and eccentric, the end of the pitman G, which is connected to the rock-arm F by an adj ustable stud, m, is broken into sections, thus exposing the thimble g, which is made separate but firmly inserted in the perforated end '5 of the pitman to provide a good wearing-surface, the thimble being made of hard brass, bronze, hardened steel, or any other suitable metal that may be preferred. The other end of the stud m is secured to the rock-arm F by the insertion of its reduced and flattenedbody through the slot, to engage with the shoulder m, and be secured in this slot by a clamping-nut, or a setbolt, W, as may be preferred.

It should be u ndcrstood that the throw of each eccentric is preferably made the same, although this is'not imperative, as, if it is desired, they may be varied in this respect without detriment to the operation of the machine.

The two rock arms F and pitmen G are alike in construction, generally speaking, the only changes made being such as are necessary to adapt them to be located on the right and left sides of the machine. Upon the upper ends of the rock-arms F rounded bosses F are formed, which have squared projections p made on them to receive thereon the mating perforated ends of, the curved burnisher carrying-arms O, which are held in place by bolts which are inserted through holes 19 made in the squared projections 19, above mentioned.

The burnisher-arms O, which are removably secured to the-bosses of the rock-arms, as has been described, are preferably curved ontwardly on each side of the machine, with their. free ends projecting horizontally a proper height above the floor of the room in which the machine is located, so that they will present the burnisherswhich are affixed tothese ends in convenient position for use by workmen who operate on the machine.

The metallic polishing-tools d d are made adjustable to the outer ends. of the arms 0, which carry them, and are affixed securely by bolt-connection or other approved means, so that different forms of tools to finish the edges, shank, top,'and heel of a shoe or boot may be attached quickly and exchanged when another shape is needed. sets of burnishing apparatus, one on each side of the machine, are distinct from each other, their only connection being the common support afforded by the base-plate A, and alsoin having one source of motion and power to drive them.

The irons d, so called, are actually made of steel hardened and highly polished, they being shaped to suit the work they are to perform, and as it is necessary that they be heated before use gas may be conducted to thesetools by flexible hose in an obvious manner, which when ignited to burn from a proper burner will by contact of its flame heat the irons at when this is necessary.

In some cases it may be preferred to employ a lamp instead of gas to heat the tools (I d. With this end in view I provide lamps, one for each side of the machine, which will direct by their extended wick-tubes a suitable flame upon the irons when needed. These lamps are supported upon bracket-plates K, that are provided with perforated bosses t, which are placed over and upon the outer extremities of the extended ends of the rock-arm-supporting studs I.

The bracket-plates K may be made as shown on the right-hand side of the machinein Fig. 1, or with a deep retaining-flange, K around its edge, as shown on the left side in the same figure.

The perforated bosses I on the bracketplates K answer two purposes. The first has already been indicated. The other consists in their use as a retaining-abutment for the rock-arms F, the hubs F of which are in contact with the adjacent ends of these bosses t. The other ends of the elongated hubs F of rock-arms F are secured to rock easily, but without objectionable end-play, by the adj ustingnuts e e, that have threaded engagement with the studs I, as shown in Fig. 1.

Upon one or both projecting ends of the spindle B, as well as the peripheral surface of the spindleat one or both its ends, brushes D are affixed, as shown, so that these brushes will be available for use by a workman who is burnishing work on the irons d,these brushes, from their construction, being convenient to polish any portion of the burnished work, or the entire shoe, if necessary.

In the drawings, Fig. 3, Ihave shown asingle brush attached to one end of shaft'B; but it is evident that a similar brush can be attached to the opposite exposed end of said shaft.

It is evident that the two IIO It will be understood from the foregoing description that the changing of adjustment of the ends of the pitmen G will cause the rockarms F to have a greater sweep if these pitman ends are secured in the elongated slots of the rock-arms near to the hubs F of the same, and a change of adjustment of the pitmen toward the upper ends of the slots f will shorten the are of vibration given to the burnishingtools (I, so that any desired reciprocatory motion may be transmitted to the burnishingirons d d in the manner stated. It will also be apparent that the movement of one burnishing-iron may be adjusted so that it will travel through a longer are than the other and with increased speed per inch of surface travel, although both eccentrics are of equal throw and actuated by the same spindle. This feature of my machine is of great advantage, as two workmen may be employed at one machine, and as one operator finishes the edge or heel with a short stroke the other party may opererate with a long quick stroke on the shank of a boot or shoe, and they may exchangepieces, so that the work is expedited with less handling than usual in such operations.

It should be stated that the burnishing of top pieces at the toe and edge setting may be effectually performed on this machine by a proper form of irons.

In operating the machine from the position and height given to the burnishing-irons the workman will be enabled to hold the work against his breast to steady it and also apply Many slight changes might be made in the details of construction of this device without a departure from the spirit or scope of my invenvention; hence I do not wish to confine myself to the exact forms herein shown; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
