'ALEX A. CLARKE, or DALLAS, TEXAS.
SURFACE-TREATING MACHINE.
' Application filed April 26,
To all whom it may concern:
Be it known that I, ALEX A. cm, a cltizen of the United States; residing .at
' Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements 1n Surface-Treatmg Machines, of which the following is a specification. a
This invention relates to new and useful improvements in surface treating machines. The purpose of the invention is to provide a machine in which the surface treating member is driven by intermediate means from a motor displaced from the member,
provided on the frame manipulating the same. A surface treating member is mounted in the frame and may assume the form of a sleeve fitting on a drum. A motor is mounted in the frame and a train of gears driven by the motor operates the member.
By adjusting the frame the member is raised and lowered andgsuch meansis employed.
The invention will be more'readily understood from'a reading of the following SPGCi'.
-fication and by reference to the accompany.-
'the1r sides and these receive plates 21 which.
are fastened thereton The ing drawings, in which an example of the inventionfis shown and wherein:
Figure 1 is a side elevation of a machine embodyingt e invention,
Fig. 2 is a artial plan view of the same, Fig. 3 is a detail of the runner and cross bar connection, v
Fig. 4 is a side elevation of .a modification,
Fig. 6, is a vertical sectional view line 6-6.0f Fig. 5, and p Fig. 7 is a partial plan view of the ma on the chine shown in Fig.5.
are fastened to the end members by screws 4:. 7 The end members having vertical columns 5 at each side in which posts 6 are mounted. Each post has its lower" end reduced and fastened in a cross bar 7 as is shown in Fig. 3. The cross bars project g Fig. 5 is a side elevation of still another "form,

beyond the posts and have reduced ends 8 fitting runners 9 and fastened therein by set screws 10. The runners extend longitudinally of the machine and have their proectmg ends turned up so as to avoid scratching the surface being worked on.
At the top of each=column a boss 11 is provided and a small sprocket wheel 12 screwthreaded on the post is mounted on each one. Keepers 13 fastened on the end members confine the sprocket wheels 12 and. support (the 'frame. The posts are not threaded in the columns and thus by rotating the wheels 12 the latter are elevated or lowered on the posts, thereby elevating of lowering the frame. An endless sprocket chain 14; extends around the machine'and' engages the wheels 12. This chain passes aroundan idler sprocket wheel 15 at one end and driven by a sprocket wheel'16 at the other end. The wheel 16 is fastened on a shaft 17 rotated by ahandle 18 which with a companion handlel8' at the other end ismounted between brackets 19. The wheels 15 and 16 are supported on the upper brackets. These brackets extend from and form parts of the end members 3. By rotating the handle 18 the chain is traversed and the wheels 12 I simultaneously rotatedthus evenly. adiusting'the frame and main taining its leve The columns 5 have ears20 set back from 21 have their lower edges some distance above the lower edges of the plates 2 and are arched above drums 22 and, 24. The.
drum 22 has trunnions 23 engaging in the side plates 2, while the drum 24;.also' has trunnions 25 engaging in said plates. 'By
removing the rear side plate 2 (Fig. 1) the drums may be removed. A sleeve 22 is. fitted on the drum 22 and a sleeve 24' is fitted on the drum 24. The sleeve 22' may be of coarse abradin material and the sleeve 24 of fine abra ing material so that when the machine is moved to the left (Fig. 1) the coarse abrading member will first attack the work followed by the fine abrading member. The sleeves may be of polishin or buffing materials if desired,
n the space between the plate 2 and 1 plate 21 at the front side (Fig. 1-) of the machine gears .are disposed. are fastened on the trunnions 23 and 25 Gears 26 and each meshes with a gear 27. The gears 27 are driven by a common driving pinion 28 fastened on a motor shaft 29. A motor 30 is mounted between the plates 21 on brackets 31. The sizes and relations of the gears may be changed if desired to obtain various speed ratios.
By supplying current to the motor the drums are revolved. The operator moves the machine over the work and the surface is removed, polished or treated according to the nature of the sleeves used. The drums are readily adjusted by turning the handle 18.
In Fig. 4L I have shown a modified form substantially the same as the machine just described except that only a single drum 40 is employed. This drum has a surface treating sleeve 40 and trunnions 41. A gear 42 is fastened on one of the trunnions and is driven by a gear 43 which meshes with the pinion 28 of the motor shaft 29. The motor 30 is mounted nearer one end of the frame and the machine is shortened. In Figs. 5 to 7 inclusive I have shown another form in which the invention may be employed. In this instance the runners 9 cross bars 7 posts 6 s rocket wheels 12, and keepers 13 are used. n end member 50 and a shorter end member 51 are used. The end member 50 has vertical columns 52 at each side receiving the. posts at one end of the frame. Ears 53 cast on the columns are set back from the outer sides of the same. Ears 54 are provided on the end member 51. Side plates 55 connect the end members and are fastened to the ears 53 and 54. Lugs 56 are provided on the side plates and receive the other pair ofposts.
The end members have outwardly extending brackets 57. A handle 58 is fixed between the brackets of the member 51; while a handle 58 is rotatable between the brackets of the member 50. The handle 58 has a shaft 59 extending above its top bracket with a sprocket wheel 60 fixed on said shaft. An endless sprocket chain 61 passes around the sprockets 12 and 60 and by turning the handle 58 the chain is traversed as in the other forms, thus adjusting the frame.
The end members have ears 63 spaced inwardly from the ears 53 and 54 and inner plates 62 extending between the endmembers are fastened to the ears 63. Below the inner plates at cross bar 64 fastened to the side plates braces the same. The side plates are cut back at their lower left-hand (Fig.
5) corners and provided with collars 65 receiving the shaft 66 of a drum 67 having a surface treating sleeve 67 The purpose of this arrangement is to dispose the drum at one end of the frame and to one side of the adjustable supports. It will be seen that if the handle 58 and its brackets 57 were omitted the drum would extend beyond the end of the frame. A gear 68 is fastened on the drum shaft 66 and is driven by a gear 69 mounted between the plates 55 and 62 thereabove. The gear 69 meshes with a pinion 70 mounted on a motor shaft 71 of a motor 72. The motor 72 is mounted on brackets 73. The operation is the same as in the other forms.
What I claim, is:
1 In a machine of the character described, a supporting frame, upstanding apertured members secured to the supporting frame, approximately vertical osts longitudinally movably mounted within the apertured members and having their upper portions screw-threaded, said posts extending below the supporting frame and adapted to support the same, sprocket wheels having screw-threaded engagement with the screw-threaded portions of the posts, means to prevent the sprocket wheels moving vertically with relation to the supporting frame, a sprocket chain connecting the sprocket wheels, a sprocket wheel engaging the sprocket chain, means to turn the last named sprocket wheel, a surface treating member connected with the supporting frame, a motor carried by the supporting frame, and gears connecting the motor and the surface treating member.
2. In a machine of the character described, an outer supporting frame embodying a removable side, an inner frame secured to the outer frame and having a side spaced from the removable side, a rotatable surface treating member detachably connected with the sides of the outer frame, a gear permanently secured to one end of the rotatable member and arranged-between the spaced sides of the inner and outer frames, a motor arranged within and secured to the inner frame, gearing connecting the motor and the first named gear and arranged between the spaced sides, a support connected with the outer frame, and means to vertically adjust the outer frame with relation to the support.
In testimony whereof I affix my swuature.
