Rohischung, Kalamazoo, Mich, assignor to Hammond Machinery Builders, Inc., Kalamazoo, Mich, a corporation of Michigan Filed Aug. 27, 1962, Ser. No. 219,397 4 Claims. (Cl. 51-135) This invention relates to abrasive belt metalworking machines and particularly to a type thereof utilizing a belt of the order of from four inches in width to as little as one-eighth of an inch in width and readily adaptable to a wide range of specific uses.
Although the use of abrasive belt metalworking machines is not new, these machines have, insofar as I am aware, usually been confined to somewhat specialized uses, or at least any given machine has been capable of only a relatively narrow range of possible uses. Hence, there has remained a need for an abrasive belt machine, especially one adaptable for polishing the contours of irregularly shaped articles, which is extremely versatile and capable of handling a Wide range of shapes and sizes of articles. However, the filling of this need creates certain problems in that the adapting of such a device to a wide variety of specific uses involves the provision of contact wheels of various diameters, widths, degrees of softness and other characteristics together with the provision of sufficient varying ways of mounting the contact wheel as to permit it to cooperate properly with workpieces of many different shapes.
Some initial attempts to meet these needs have been made in the machine illustrated in the United States patents to Bader No. 2,578,662 and No. 2,763,103, and these machines have achieved some commercial success. However, the constructions involved in these patents, and others of similar nature,.have not been wholly satisfactory, particularly at the point of providing good sensitivity of belt-tracking adjustment and at the point of providing, good versatility or adaptability to different types of work, and it is therefore desired to provide a machine which improves over the prior art at these and other points.
Accordingly, the objects of the invention include:
(1) To provide an abrasive belt machine having a high degree of versatility for handling irregular and contoured workpieces of a wide variety of shapes and sizes.
(2) To provide a machine, as aforesaid, which will effectively polish a number of different surfaces both concave and convex in articles of relatively small size and complex curvatures, such as golf club heads, cutlery, firearms, jet engine parts, plumbing goods, household and marine hardware, and the like.
(3) To provide a machine, as aforesaid, having a pinrality of contact wheels, or heads, and in which machine said heads can be quickly and easily changed from one to another as desired to accommodate various kinds of Workpieces.
, (4) To provide a machine, as aforesaid, wherein one contact wheel may be freely interchanged with a variety of other contact wheels of differing diameters, widths or materials.
(5) To provide a machine, as aforesaid, wherein the belt-tracking means is extremely sensitive so that the belt may be adjusted by the workman during operation of the machine for riding at any desired point on the contact wheel including extending slightly over one edge thereof.
(6) To provide a machine, as aforesaid, wherein the direction of rotation of the drive pulley may be reversed, even while the machine is running and without throwing off the belt, in order to reverse the direction of move- "ice ment of the belt as needed to accommodate it to various types, sizes and shapes of workpieces.
(7) To provide a machine, as aforesaid, wherein the tensioning means for the belt may be either mechanical or fluid pressure operated, as desired, and wherein such tensioning means can be easily interchanged.
(8) To provide a machine, as aforesaid, which will be inexpensive to manufacture and which can be maintained in good operating condition with a minimum of maintenance cost.
Other objects and purposes of the invention will be apparent to persons acquainted with apparatus of this general type upon reading the following disclosure and inspection of the accompanying drawings.

Detailed Description Referring now to the drawings and particularly to FIGURES l and 2, there is shown a base 1 supporting a pedestal 2, both thereof being of generally rectangular construction preferably fabricated from suitable welded sheet stock, reinforced at 2:: (FIGURE 8) if desired, and supporting a pan 3 at the upper end thereof. A horizontal beam 4, suitably channeled to minimize weight but ribbed to provide strength, is pivoted at 6 to the pedestal 2 and clamped at 7 by any convenient clamp means anchored in a clamp plate 2b and extending through an arcuate opening 8 by which said beam 4 may be arranged as desired to raise or lower the hereinaftenmentioned contact wheel portion thereof to a convenient working height.
At the rightward end of the horizontal beam 4, as appearing in FIGURE 2, there is supported a motor 11 which is hung in any convenient manner by suitable means, such as bolts 12 and 13, from the lower surface of the beam 4. The motor 11 carries a pulley 14 on its shaft which pulley preferably is uncrowned.
The extreme rightward end of said beam 4 carries a vertically arranged split sleeve 16 which supports an upstanding tubular pulley support member 17. Clamp ing means, such as the bolt indicated at 18, is provided for holding said tubular member 17 rigidly in position. The upper idler pulley 19 is supported for free rotation on and with respect to a sleeve 21 which encircles the tubular member 17 and is vertically slidable with respect thereto. A vertically elongated slot 22 (FIGURES 4 and 5) is provided in said tubular member 17 at a suitable location thereon. A pulley tension adjusting screw 23 is coaxially arranged within said tubular member 17. Its lower end is threadedly received into a guide 24 which is vertically slidable within the tubular member 17. A rotation-preventing block 26 rides in the slot 22 and is fastened by a screw 27 to said guide 24 and prevents v3 rotation thereof. A collar 2% has an unthreaded opening 29 therein encircling the screw 23 and said collar is held fixed with respect to the sleeve 21 by a positioning block 31 which is received into a boss 32 on the sleeve 21 and which is fixedly secured thereto by a set screw 33. A screw 34 fastens the block 31 rigidly to the collar 28. A spring 36 extends between the collar 23 and the guide 24.
The upper end of the screw 23 extends through a bearing block 37 which is fixed to the upper end of the tubular member 17 in any convenient manner, such as by screws 38. An adjusting hand crank 39 is fixed to the upper end of the screw 23 and is provided with any convenient means for manual rotation, such as the knob 41. Thus, rotation of the hand crank 39 will raise or lower the guide 24 which acts through the spring 36 to control the vertical position of the sleeve 21 and thereby control the vertical position of the upper idler 19.
The upper idler 19 is crowned for belt-tracking purposes in a conventional manner.
Turning now to the means for mounting the contact wheel, a number of different devices are provided according to the size and type of contact wheel to be mounted. Referring first to the contact wheel shown in FIGURES l, 2 and 3, there is provided a yoke 51 having a smoothly machined lower surface 52 (FIG- URE 6 which is mounted on a correspondingly smoothly machined surface 53 (FIGURE 2) on the upper side of the leftward end of the beam 4, the same being held thereon by any convenient means such as screws of which one appears at 54. The yoke 51 is provided with upper and lower arms 56 and 57 between which is pivotally mounted a bearing housing 58. The bearing housing 58 has vertically extending pivot pins 60 and 6th: which are pivotally supported in the arms 56 and 57, respectively, for pivotal movement about a vertical axis A. The bearing housing 58 contains conventional bearing units, of which one is partially indicated at '9 (FIG- URE 7), and within which is mounted a shaft 61. The shaft 61 is threaded at its leftward end for the reception of nuts 62 and 63 between which is mounted in a known manner the con-tact roller or wheel 64. As shown in FIGURE 7, the wheel consists of a pair of metal plates 66 and 67 between which are retained layers of soft bufiing material generally indicated at 68.
The belt-tracking adjustment means comprises a flange 71 which extends laterally from the bearing housing 58 and through which extends a shaft 72. The shaft 72 has a shoulder 73 which abuts against the flange 71, an operating knob 74 at one end thereof and a threaded end 76 at the other end thereof. Said threaded end 76 is threadedly received into the opening 77 in the yoke 51. A spring 73 encircles the shaft 72 between the yoke 51 and the flange 711 for urging said flange against the shoulder 73. Thus, rotation of the knob 74 in one direction will effect a clockwise (as seen in FIGURE 7) rotation of the housing 58 around the pivot pins 60 and 60a while the rotation of the knob in the opposite di rection will permit the spring 78 to effect a counterclockwise rotation of said housing about said pivot pins.
Inasmuch as the location of the axis A about which the housing 58 pivots is as close as possible to the vertical diameter through the wheel 64, it will require only a very slight pivotal movement of the housing 58 to effect whatever tracking control is required. Thus, the tracking of the belt can be made extremely precise and, with the knob 74 within convenient reach of an operator seated in front of the wheel 54, the desired control over tracking is rendered convenient and effective.
Thus, there is provided and extremely versatile abrasive belt machine which is especially adapted to the finishing of a wide variety of different kinds and sizes of irregular and contoured workpieces. Particularly, the versatility of this machine is enhanced by providing the machine with the ability to receive contact wheels of many different sizes, types, styles and means for supporting same all of which can be readily interchanged with respect to each other and wherein such interchanging either (a) will not upset previously established belt-tracking adjustments, or (b) if a new belt-tracking adjustment is required it may be readily and simply carried out by the workman without his leaving his normal position of use of the machine.
