Specification of Letters Patent.

Application filed December 31, 1912. Serial No. 739,503. 8

To all whom it may concern:

Be it known that I, WVILLIAM C. I'IAZLE- TON, a citizen of the United States, residing at Delaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Cement-Block- Tamping Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to plastic block tamping machines and has for its object the production of an efficient machine for packing the cement within the mold so as to cause the plastic material to mold in a solid body without having any porous portions formed therein.

Another object of this invention is the production of an efficient machine which consists of a minimum number of parts and is efficient in operation.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings :F igure 1 is a side elevation of the machine. Fig. 2 is a front view thereof. Fig. 3 is a central vertical section of the machine. Fig. 4is a section taken on line 4-4 of Fig. 1. Fig. 5 is a section taken on line 55 of Fig. 1.. Fig. .6 is a section taken on line 6-6 of Fig. 2. Fig. 7 is a vertical section through the swinging feet, showing the connections therefor. Fig. 8 is a top plan view of the swinging feet, as indicated in Fig. 7.

By referring to the drawings by numerals it will be seen that the device is hung from supporting beams 1 and comprises a frame constituting a pair of depending side members 2. These depending side members 2 are braced by means of diagonally extending braces 3 and upon these side members 2 is journaled an operating or driving shaft 4:. This driving shaft 4 carries a drive pulley 5 which is driven by means of a belt 6 or any suitable driving means, and aclutch jaw 7 is fixedly secured to this shaft 4. A segmental gear 8 is slidablv mounted upon the shaft 4. and is provided with a collar 9 which collar is adapted to be engaged by the clutch finger 10 supported upon the transversely extending base bar 11 of the supporting frame. This clutch finger 10 is engaged by means of a shifting rod 12 which rod passes through a journal 13. The outer end of the rod 12 is provided with an angularly extending portion ld for facilitating the sliding of the rod 12 within the journal 13. A coil spring 15 is employed and secured at its respective ends to the finger 10 and theframe 2 so as to normally hold the gear 8 out of mesh with the rack 16 hereinafter described. It will be seen that as the rod 12 is forced inwardly, the gear 8 will be forced in engagement with the rack 16 thereby allowing the gear to operate or raise the plunger frame supporting the rack 16.

A transversely extending bracing'bar 17 is interposed between the depending members 2 of the frame, as illustrated in Fig. 2, and through this bar or member 17 and the member 11 is slidably mounted the plunger frame 18 which plunger frame comprises a pair of vertically extending rods 19 which rods are connected by means ,of a transversely extending member 20 at their upper ends. A rack supporting bar 21 is secured centrally of the transversely" extending member 20 and is held in parallel relation relative to the connecting bars 22 by means of a roller 23 which roller 23 is supported by means of a shaft 24. This shaft 24 has its respective ends journaled in the blocks 25 supported by these members 22. A rack bar 16, as previously described, is carried bythe rack supporting bar 21 and fits in a cut-out portion 26 formed upon the inner face thereof. It will, therefore, be seen that the rack bar supporting member 21 will be held in place between the segmental gear Sand the roller 23. The rack supporting member or bar 21 is provided at its lower end with a transversely extending bar 27 to which bar 27 is clamped one of thetamping feet 28 by meansofjthe clamp 29. These tamping feet are supported by means of the T-shaped connectors 30 which T-shaped connectors 30 are engaged by the connecting clips 31 havingtheir threaded ends 32 threaded in the T-shaped connectors 30 as indicated in Fig. 3. The flattened portions 33 of the clips 31 are secured to the upper faces of the tamping foot 28 by means of the bolts 34.

The rods. 19 of the frame 18 carry T- shaped joints 35 which joints support the rods 36 upon which rods are journaled the sleeves of the T-shaped supporting joints 37 of the swinging tamping feet. The T- shaped supporting joint 38 of the foot 28 is supported upon this rod 36. The lower ends of the rods 19 engage T-shaped conwith the usual clips 31 as described with nectors 39 which connectors are provided reference to the foot 28' forconnecting the feet 40 to the lower ends of the rods 19.

The swinging feet 41 are connected to the bars 42 similar to the manner in which the feet 40 are connected to the rods 19, and the T-shaped members 37 are so mountedupon the supporting rod 86 as to be swung out of position. A handle 43 is connected to the swinging feet 41 so as to allow the swinging feet to be swung up out of position from between the stationary feet 40 and the central foot 28. These swinging feetmay be thrown to the position as shown in dotted lines in Fig. 1 when it is not desired or necessary to use them. Strap members 44 span the swinging 'feetas illustrated in Fig. 6 and are adapted to limit theswinging of the feet inone direction. The transversely extending bar 27 is held in engagement with the rods 19 by means of the securing clips 45 as illustrated in Fig. 6. g

A hand lifting lever 46 is pivotally secured to a vertical beam 47 as illustrated in Fig. 1' and to this hand lifting lever 46 is connected the cable'48 which is connected to the vertical sliding frame 13 after passing'over a block 49. It will, therefore, be seen that the feet 28, 40 and 41 may be lifted out; of place by hand when it is not desired tooperate the shaft 4 by means of the pulley 7 wheel 5.

From the foregoing description it will be seen that a very eflicient and easy operated device has been producedwhereby the slidin'g frame may beeasily controlled in order to allow the plastic material within the V mold to be thoroughly compressed by means of the hammering of the feet 28, 40 and 41 upon the plastic material within the mold.

'As will be seen in Fig. 3, the segmental gear 8 is provided with a blank portion 8 which will cause the sliding frame to drop after each half revolution of the segmental gear 8. This will cause a reciprocating mo,- tion of the frame 18 thereby'constit'uting an efficient packing means. Of course, when it Copies of this patent may be obtainedfgr Coil springs 50 are connected at their lowed ends to the transversely extending member 11 of the frame and have their upper ends engaging the upper end of the bar '21 so as to normally exert a downward face of the rack supporting member or bar' 21 so as to constitute a track for the roller 23 as illustrated in Fig. 3.

Having thus described the invention, what is claimed as new, is

l. A device of the. class described comprising a main frame, a reciprocating frame comprising a pair of side bars, a T-shaped joint connected near the lower end of-said side members, stub shafts engaging said T-shaped joints', a T-shaped joint connecting the adjacent ends of said stub shafts, a pipe section depending fromsaid last mentioned T-shaped joint, a stationary-foot supported or suspended from the lower-end of said pipe section, pipe sections extending from the lower ends of said sidemembers, stationary feet secured to the lower end of saidlast mentioned pipe sections, and swinging feet journaled upon said transversely extending stub shafts and adapted tobe swung out of engagement with said stationary feet. A

2. A device of the class described comprising a reciprocating frame, stationary feet carried by said frame, a transversely extending supporting shaft carried by said frame, swinging feet supported upon said shaft, each foot comprising a body, clips secured to said body, joints connecting said clips, means for connecting said feet to said transversely extending bar, a lifting handle connecting said swinging feet together, and transversely extending braces secured to said stationary feet and adapted to overhang said swinging feet for limiting the swinging movement of said swinging feet in one direction.
